Role of computers in Human resoruce management

In a recent study it has been found that 60% of HR costs are devoted to administrative activites

like record keeping and paper shuffling, 3o% of costs and efforts are devoted in the area ofrecuritment, training, counseling performance management etc., and 10% of costs are devoted to

strategic planning ie., compensation, development, manpower planning etc., From the above it siclear that our efforts go into those tasks that return the least value.

Information technology leveraged HR systems can be used to save the costs and to increase theemployee satisfaction.

Advantages of information technology in HR are the following

1. Training and Development

With the help of IT the classroom training has come to actual work place. For older older

industries like textiles, training is a prime requirement even for it IT implementation. Hencetraining programs are planned for practical sessions after theory session. Training and

development programs are made more effective and interactive eith the use of multimedia. Using

television, videos, CD-ROM and internet, quantum improvement in effectiveness and reductionin cost can be achieved and training inputs can be given to sizeable number of people.

2. Recruitment

IT has brought revolutionary change in recruitment with the help of internet. Company can

develop their own web-sites so that as and when the requirements comes the profile require is put

on the own web-site or thorugh commerical web recruitment sites. The organisation can have

rich databank of candidates and can choose the candidate whose profile is best suitable to theirneed.

3. Performance Appraisal

The performance appraisal system has also improved with the help of IT. Appraisal forms onpaper is replaced by electronic forms on corporate Internet. Each employee can access their won

appraisal forms. The appraiser can consult other related persons during performance

management procedure.

4. Communication

Today with the helpof Internet, one can reach to any corner of the world within a second.Usingcommunication related softwares paperwork can be eliminated and can spend more time for

development and creativity. It makes human resource management process more prompt,

confidential and responisble.

5. Call monitoring system


2/20

IT records all the calls made outside with time duration, units and cost of all. This system

helps in monitoring communication cost.

6. Spy guard system

Spy guard is a vigilance system to keep a close watch on the movement of security guards.System consists of clock units, key stations, reader units, computer and printers. This gives

accurate and constant record of guards movements, date, time and key station number.

7. Attendance recording system

This system not only helps to enforce a sense of punctuality and sincerity in the employeesbut also helps the management through various reports, which are generated for

Not reported status

Immdediate strength report

Late arrivals, over stay, early departure Absenteeism

Attendance register

8. Salary and Wage Administration

Salary and wage administration in any textile unit is the most complex compared to other

manufacturing units. Here employees get wages depending on the importance of work, on the

complexity of a particular machine, on shift, on the production efficiency and on seniority of

employees.

9. Leave Accounting system

This system helps in monitoring,

Attendance of employees

Continuous absenteeism

Section/ department wise absenteeism

Month wise absenteeism

Leave without pay

10. HR Database Management

Maintenance of employee record and ability to generate information as and when required is

now a measure of the effectiveness in handling peoples issue. It is very important that the

right data is made available for use at right time.

Management information system

A management information system (MIS) is a subset of the overallinternal controls of a

business covering the application of people, documents, technologies, and procedures bymanagement accountants to solve business problems such as costing a product, service or a

business-wide strategy. Management information systems are distinct from regular information

systems in that they are used to analyze other information systems applied in operationalactivities in the organization.[1] Academically, the term is commonly used to refer to the group of

information management methods tied to the automation or support of human decision making,

e.g.Decision Support Systems, Expert systems, andExecutive information systems.[1]

It has been described as, "MIS 'lives' in the space that intersects technology and business. MIScombines tech with business to get people the information they need to do their jobs

better/faster/smarter. Information is the lifeblood of all organizations - now more than ever. MIS

professionals work as systems analysts,project managers, systems administrators, etc.,communicating directly with staff and management across the organization." [2]

[edit] Overview

At the start, in businesses and other organizations, internal reporting was made manually and

only periodically, as a by-product of the accounting system and with some additional statistic(s),and gave limited and delayed information on management performance. Previously, data had to

be separated individually by the people as per the requirement and necessity of the organization.

Later, data was distinguished from information, and instead of the collection of mass of data,important, and to the point data that is needed by the organization was stored.

In their infancy, business computers were used for the practical business of computing the

payroll and keeping track of accounts payable and accounts receivable. As applications were

developed that provided managers with information about sales, inventories, and other data thatwould help in managing the enterprise, the term "MIS" arose to describe these kinds of

applications. Today, the term is used broadly in a number of contexts and includes (but is not

limited to): decision support systems, resource and people management applications, ERP, SCM,CRM, project management and database retrieval application.

An 'MIS' is a planned system of the collecting, processing, storing and disseminating data in the

form of information needed to carry out the functions of management. In a way it is a

documented report of the activities that were planned and executed. According toPhilip Kotler"A marketing information system consists of people, equipment, and procedures to gather, sort,

analyze, evaluate, and distribute needed, timely, and accurate information to marketing decision

makers."[3]

The terms MIS and information system are often confused. Information systems include systemsthat are not intended for decision making. The area of study called MIS is sometimes referred to,

in a restrictive sense, asinformation technology management. That area of study should not be

confused with computer science.IT service management is a practitioner-focused discipline.

MIS has also some differences withEnterprise Resource Planning(ERP) as ERP incorporates

elements that are not necessarily focused on decision support.

ProfessorAllen S. Lee states that "...research in the information systems field examines more

than the technological system, or just the social system, or even the two side by side; in addition,it investigates the phenomena that emerge when the two interact." [4].

MANAGEMENT INFORMATION SYSTEM is defined as :-1)Provides information support for decision making in the organization

2)MIS is an integrated system of man and machine for providing the information to support the

operation .

3)MIS is defined as a computer based information system.

What are Management Information Systems?

Definition: Management Information Systems (MIS) is the term given to the discipline focusedon the integration of computer systems with the aims and objectives on an organisation.

The development and management of information technology tools assists executives and the

general workforce in performing any tasks related to the processing of information. MIS andbusiness systems are especially useful in the collation of business data and the production of

reports to be used as tools for decision making. Applications of MIS With computers being as

ubiquitous as they are today, there's hardly any large business that does not rely extensively ontheir IT systems.

However, there are several specific fields in which MIS has become invaluable.

Strategy Support

While computers cannot create business strategies by themselves they can assist management in

understanding the effects of their strategies, and help enable effective decision-making.

MIS systems can be used to transform data into information useful for decision making.

Computers can provide financial statements and performance reports to assist in the planning,

monitoring and implementation of strategy.

MIS systems provide a valuable function in that they can collate into coherent reports

unmanageable volumes of data that would otherwise be broadly useless to decision makers. Bystudying these reports decision-makers can identify patterns and trends that would have remained

unseen if the raw data were consulted manually.

MIS systems can also use these raw data to run simulations hypothetical scenarios that answera range of what if questions regarding alterations in strategy. For instance, MIS systems can

provide predictions about the effect on sales that an alteration in price would have on a product.

5/20

These Decision Support Systems (DSS) enable more informed decision making within an

enterprise than would be possible without MIS systems.

Data Processing

Not only do MIS systems allow for the collation of vast amounts of business data, but they alsoprovide a valuable time saving benefit to the workforce. Where in the past business information

had to be manually processed for filing and analysis it can now be entered quickly and easily

onto a computer by a data processor, allowing for faster decision making and quicker reflexes forthe enterprise as a whole.

Management by Objectives

While MIS systems are extremely useful in generating statistical reports and data analysis they

can also be of use as a Management by Objectives (MBO) tool.

MBO is a management process by which managers and subordinates agree upon a series ofobjectives for the subordinate to attempt to achieve within a set time frame. Objectives are set

using the SMART ratio: that is, objectives should be Specific, Measurable, Agreed, Realistic and

Time-Specific.

The aim of these objectives is to provide a set of key performance indicators by which anenterprise can judge the performance of an employee or project. The success of any MBO

objective depends upon the continuous tracking of progress.

In tracking this performance it can be extremely useful to make use of an MIS system. Since all

SMART objectives are by definition measurable they can be tracked through the generation of

management reports to be analysed by decision-makers.

Benefits of MIS

The field of MIS can deliver a great many benefits to enterprises in every industry. Expert

organisations such as the Institute of MIS along with peer reviewed journals such as MISQuarterly continue to find and report new ways to use MIS to achieve business objectives.

Core Competencies

Every market leading enterprise will have at least one core competency that is, a function they

perform better than their competition. By building an exceptional management informationsystem into the enterprise it is possible to push out ahead of the competition. MIS systemsprovide the tools necessary to gain a better understanding of the market as well as a better

understanding of the enterprise itself.

Enhance Supply Chain Management


6/20

Improved reporting of business processes leads inevitably to a more streamlined production

process. With better information on the production process comes the ability to improve the

management of the supply chain, including everything from the sourcing of materials to themanufacturing and distribution of the finished product.

ERP Enterprise Resource Planning

ERP system is integrated with a RDBMS system. ERP is a software infrastructure that helps to

manage the different parts of a company or business. The aim is to improve the cooperation andinteraction between all the department such as the products planning, purchasing, manufacturing,

sales and customers service department. It is the planning of the 4Ms Man, Money, Machine

and Materials. ERP is a strategic tool, which equips the enterprise with the necessary capabilities

to integrate and synchronise the isolated functions into streamlines business processes in order togain a competitive edge in the dynamic business enviroment.

The texpert software is developed using MS Visual studio and can be operated with any RDMS.

This software can operate smoothly even in a multi unit environment where the centralizeddatabase serves comparing different unit performance.

Robot and its role in Textile Industries

Robot has been defined by the Robot Institute of America as follows

An industrial robot is a reprogrammable, multifunction manipulation.

It is designed to move material, parts, tools or specialised devices, through variable programmedmotions, to accomplish a variety of tasks. The terms reprogrammable, multifunctional,

variable programmed and variety of tasks are key words that differentiate robots from special

purpose or fixed automation. As flexible automation, a robot must have the ability to adapt tomany different kinds of jobs. It must perform these jobs with some degree of dexterity and

flexibility in its motions.

Components of robot

Many industrial robot manufacturers are producing a variety of robot configuration with various

capacities and capabilities. Robots have three common basic components.

Manipulator

The skeleton, muscles and nerves comprising the mechanical unit that does the actual work.

Manipulators consist of mechanical linkages and joints, actuators, control values and feed back

devices.

Controller

The robots brain that directs movement of the manipulator

Power supply

The heart that provides the regulation energy for the manipulators activation.

The device essential to peform a specific task in the textile plant is attached to the robot arm or

tool mounting plate, called as end effecter or end-of-arm tooling, can be custom designed tomeet the needs. IT can be simple gripper that can hold a tool, a device that can insert into a cone

for moving or whatever is necessary to perform the task.

Mechanical arm

The motion to the mechanical aem may be linear aem motion or rotational motion. The

combination of motions included in the arm will determine the type of arm geometry which ispresent. The basic geometries include rectangular, cylindrical, spherical and jointed spherical.

With a comibination of these motions the arm can move to any required position within the workarea.

External power source

The power source required to operate a robot system includes the electricity to power theelectronic controller and a hydraulic or pneumatic source to operate the arm motion and end-of

arm tooling.

Robot controller

The controller is a special purpose computer which has all the elements found in computers. Thiscontroller has a network, each having a different responsibilty within the controller has the

primary responsibility for controlling the robot arm and work cell operating.

Basic Robot System

Teach stations

They accomplish three objectives

1. Powering up the robot and preparing it to be programmed.2. Writing and teaching programs that result in the solution of macufacturing problem

3. Executing proagram in the product cell.

There are many classification techiques avaiblable, out of which robot arm geometry

classification divides robots into categories based on the shape of the work area produced by the

robot arm. According to this technique robots can be rectangular, cylindrical, or spherical withsibgroups within the spherical classification. Another technique divides robots into low, medium

and high technology machines.

Robots can be classified as

1. Dedicated robot2. Machine attending robot

3. Transport robot

Robot Spinning Mills

Bale selection and feeling

The role of robot in the modern yarn manufacturing plant,where a bale of cotton selected forprocessing, is in removing is in removing it from the warehouse on a first-in, first-out basis.

It will transported to an opening area where ties and bagging will be removed automatically.

The blending feederes will be running at a uniform high speed enabling the robots to have

more materials.

Blow room

In the opening and cleaning section, waste at all points will be individually collected in

container under the respective vaccuum tanks. As the level of waste in each container

reachers top, the container will be picked up by a robot and transported to a press, where the

waste will be compressed and again the robot will return the container to its original locationunder the vaccuum tank to receive more waste.

Carding

The cards will be doffed automically and at random, with specific lengths of sliver. Therobots will be programmed to pick up cans from each card, place them onto a sliver truck,

For instance, eight cans from eight different cards can be placed on each truck and

transported to staging area for drawing for conventional operation. This will provide for

excellent cross blending and it will be a simple matter for an operator to creel the cans fromthe truck into the drawing frame.

Drawing

The drawing frames will run continuously and doff automaically. The robots will be used to

transport the doffed cans to the next processes.

Automatic sliver can replacement in OE


11/20

The automated link system feeds the cards which fill rectangular sliver cans and these are

doffed automically and then collected by a Swedish robot which services the OE machine

where it will remove empty cans, replace therse with filled cans of ready-to-spin sliver andthen complete the cycle by connecting the new sliver to the old so that spinning need not stop

for a can change.

A similar approach is being developed by Schlafhorst with its can cart which also takes full

cans of sliver from a buffer stock and delivers them where needed on the OE machine andremoves the empty cans. This also inserts the new end of sliver into the condenser of the

spinbox. The system is activated by a monitor which signals the supply system when sliver

has run out and a spindle is stopped.

Roving

With the aid of robot, it will be possible to doff roving frames automically straight into

spinning creel sections. Spinning creels will be electronically summoned immediately prior

to the time they are needed and transported to the spinning frame sections designated forcreel piecing. The length of each spinning frame will be determined not only by ring size and

gauge, but also mutiples of the number of spindles on roving frames.

Spinning

Spinning frames will run continuously, with each spindle being doffed and peiced

automatically and randomly. This will be accomplished by an automatic piecer-doffer whichis being mounted on and will patrol each side of each spinning frame. Each bobbin will run

until it becomes full, at which time it will be stopped, doffed and te end pieced up

robotically. This will allow for efficiencies approaching very close to 100%.

The spinning frames will be designed with more narrow gauge and ring sizes, considered lessthan two inches for medium count yarns as this will permit much higher front roll speeds

thoe normally being run today. The doffing and piecing robot will deposit bobbins at the end

of the frame into doff boxes which, when either full or as needed, will be picked up bytransporting robots and taken to the winding area where the yarn will be staged. The

description of each spinning doff will be loaded into a data bank.

Winding

In the winding section, all cones will be doffed automically and transported to an area where

they will be packed by robots, with all cases being strapped, weighed and labeledautomically.

All cases will be stored randomly in warehouse areas, with the description of yarn in each

carton being loaded into a data bank prior to shipping. When shipping instructions arreceived, computers will select cartons of each yarn description to be shipped on a first-in,

first-out basis. Through the use of robots, they will be transported to a loading area.


12/20

Limitations of robot

1. Cheap labour does not warrant robotisation

2. Robot is costly as it has to be imported3. The quality enhancement is not expected to be of such high value

4. Next to agriculture, textile industry is a major layout dependent employmentgenerator, and robotisation would lead to employment crisis.

After many years of professional development in process automation and quality control forcompanies of different markets, Sierra was born in 1988 with the goal to pay special attention to

the embroidery industry.

The productive process orientation (instead of task orientation)

has given us a clearer vision of whole activity of each type of

company. In particular, for the embroidery industry it is prettyobvious that the different tasks should be strongly coordinated

(task orders, design creation, embroidery production, etc.) to getthe needed quality. Any task that was not well done or any

trouble in productive process can lead to important lost.

We believe that the market opportunities of each company are

in direct relation with the managers commercial vision and thecompetitive level of their production. In this last point is where

Sierra want to help you through technological solutions,

allowing better production conditions, tasks simplification and

control improvement.

First Generation

The first Sierra development for the embroidery industry was a complete automation of very old

embroidery machine, from the first generation. These machine works thanks to a device called

jacquard that read the designs mechanically from a 68mm cardboard tape (wide). Then thejacquard transforms that reading into frame movements, again mechanically. Those machines

cannot read disks, and have only one engine to both needle and frame movement and jacquard

reading. Logically that device is the most sensible part of the machine and has frequent and

expensive maintenance requirements. It is not possible to edit designs in the tape, just fewcorrections that are extremely difficult. The production speed of these machines rarely surpass

350 stitches per minute, because mechanical limitations.

When Sierra automates the embroidery machine (BordoCDM System), the designs can be read from disk in

standard code, browse designs from a directory (in the

original version was show in text, but in later version


13/20

was in graphical format), you can edit and modified designs in a easy way, a new electronic

pantograph with 2 engines improves substantially the embroidery quality, the production speed

can reach 450/750 stitches per minute and the maintenance requirements are minimal. Theautomation was develop in a way of a flexible kit, easily adaptable both to standard and

bridge type. Still today there are a lot of automatic Sierra machines working in many countries,

with almost no maintenance. Most of the features that perform that system are common in lastgeneration machines.

Tape Reader: Sierra develops a 68mm tape reader (Bordo WT) that allow convert design from

the tape to a standard code in a computer or directly to the Sierra automation installed in an

embroidery machine. The huge amount of designs that an embroiderer store in big anuncomfortable warehouse can be transform to computer files, stored in a computer or just few

diskettes (minimum space required) and converted to a different codes to be use in a Sierra

automation system or a brand new machines.

Tape Puncher: Sierra develops a tape puncher (Bordo WP) that allows file conversion to tape to

be used in first generation mechanical machines. Which is the goal of that puncher? For somemechanical machines (generally the smaller) the automation was not viable because was not

cost-effective. In order to supply with designs at lower cost, that were created at a computerprogram and then converted to tape.

Second Generation

The second generation of embroidery machines includes the electronic type models, where thedesigns came in a telex type tape (8 channels) and are read electronically. Those machines are

functionally more complete than the mechanical machines, but yet very limited in compared with

present models and also compared with Sierra automation system. As an example, some models

dont have design memory and some have just very little memory. These machine works athigher speed than the originally mechanical machines; bit has their weakness in the low

flexibility of tape designs.

For those machines Sierra develop a system (Bordo CD)that allow the machines works directly from disk, seek

designs from a graphical catalog or standard diskette,


14/20

show the design on the screen, see color sequence, edit and modified it, and up to code

conversion. Once the machines was modified by Sierra, they can be connected between them

allowing the computer where the designs are read and edit send them to many embroiderymachines, still from different models. This was the born of a connectivity concept.

Third Generation

The models from this generation are those offered by the manufactured presently in the market.

Most of those machines are at the present technology boundary so they dont have anycompetitive or productivity problem (could be improved, but with extremely high cost). Then,

which is the problem with these machines? Unfortunately the manufacturers doesnt agree about

disk codes, or memory boards or kind of communication between machine and computer. Theworst part is that the users suffer from this because it is not possible to work with two machines

from different brand equally; and in some cases, it is not possibleto work in the same way with two machines of different modelfrom the same brand!

When is possible (that is not ever) connectivity products from

Sierra allow to send designs to machine avoiding diskettes, in the

same way for machines from different manufacturers and differentmodels; still with embroidery machines from different generation.

The connection type can be direct (the chipper ones) or in a

network (Bordo Net) that more expensive but include very easy design administration.

Software

With the idea to bring a more extensive and complete products line applied to the embroideryindustry, after an study about the needs of the companies and the market existence offer, Sierra

starts a new project called Bordo CAD that allow embroidery design creation from a computer.

The original goals of this project lead us to build an innovative and unique system, as for theirvery friendly interface (rarely found on system from that time) as for the organization,

productivity and embroidery quality achieve. This system was the predecessor of EO Design,

included in the Embroidery Office line of products.

When the yarn in the cone is in the exhaust stage the sensor senses the cone diameter and it

passes signal to the control unit. Then the control unit will pass the signal to the lamp to indicate

In case of needle breakage, a bulge is formed on the yarn because of continuous feeding of yarn.

Now the needle detector is displaced by means of bulge in the fabric. Due to the bulge formation,

the needle detector gives the signal to the LVDT, then the machine will be stopped.

Winding length:

To measure the correct amount of delivery wound on the take up roller, an elector magnetic

device is used. The magnetic coil is fixed on the rigid beam and the revolving take up roller also

has the magnetic devices. By each revolution of the take up roller the magnetic flux is created.

This magnetic flux signal is passed on to the controlling devices. This counts the number of

revolution and when the length is reached the machine is automatically stopped.

In the oil level control, the oil tank containing the two electrodes one is for upper level oil

control and othr one is the lower level oil control. When the oil level reaches the minimum level

the signal will pass to the controlling unit and the oil is filled by oil distributor to the tank. When

the oil reaches the maximum level the upper electrode will give signal to the controller and it

will control the distribution of oil.

Individual needle selection

The control system with piezoelectric bending transducer modules for individual needle selection

is tailored for use in jacquard circular knitting machines. This unit combines the following

functions in a highly compact design. Various pattern repeats, which are stored permanently on

the controller, are available immediately after a pattern change, with no time-consuming loading

from diskette.

Functions for continued knitting to pattern after a power failure increase the productivity of

machines, and prevent production rejects. The piezoelectric ending transducer modules permitlow-loss operation on the knitting machine resulting in low heat generation and a long life.

Knitting machine-needle detector

The needle sensor monitors the needle hooks o single, fine rib, jacquard and interlock circular

knitting machines without contact. It stops the machines immediately if a needle hook or butt

breaks. Depending on the type of knitting machine, the needle sensor consists of up to four

optical heads and a control unit. The optical head projects a narrow spot of light onto the needle

hooks running past, which reflect part of the light. These light pulses are fed to the control unit

via fibre-optic cable. The control unit automatically adapts to the needle sequence corresponding

to the machine speed and gauge of the needles.

If a pulse is not received due to the needle breakage, the machine control is commanded to stop.

Simultaneously with the stop signal, a needle counter begins to work. It indicates the number of

needles running past until the actual machine shutdown. This makes the localisation and

replacement of defective needles much easier. Needles missing to produces separating rows or to

create patterns are masked out. As additional security against false stops, the number of fault

repetitions before stoppage of the machine is adjustable. The piezolectric bending transducers are

at the very heart of the piezo modules and are responsible for controlling the anchors and thus

also the needles. The piezo modules are specially designed for use with the control system.

Knit Master system

The knit master control unit, which becomes a permanent portion of the knitting machine, serves

three major functions:

1. It counts all machine revolutions and will stop the knitting machine after a

predetermined number of machine revolutions.


20/20

2. It serves as a power source and control for the knit master Electronic Yarn Meter.

3. It serves as a power source for the knit master Compu-Tach, the fast and highly

accurate electronic RPM meter.

The control unit can serve as a feed source for Data Collection Systems of various types. TheKnit master Electronic Yarn Meter measures and gives an instant digital read-out of the number

of inches of yarn consumed per machine revolution, in contrast to most other meters which are

merely speedometers. As the knit master Electronic Yarn Meter is plugged into the knit master

Control Unit of a running knitting machine and the yarn is engaged in the wheel slot of the meter

head, it will immediately start to accumulate a reading. This first reading may be inaccurate, due

to the point of entry; the second reading will be absolutely accurate. It will alternately and

automatically display a reading and accumulate a new reading every other revolution of the

machine, without resetting the yarn meter.

The functions of the knit master are the following

It is used to even-up all feeds of a machine and to set each feed of a machine to a specified

reading.

It serves as a continuous Yield Control Checking System for all yarns used and for all fabrics

made; in contrast to the normally used laboratory or spot check methods; therefore, affords total

control.

It is used to determine yarns percentage in any fabric without stopping the machine and without

having to unravel and weigh yarns or having to weigh cones prior to and after sample roll

knitting. The time saving is enormous. Different amounts of different colour, size or type ofyarns in fabrics can be simply calculated by the use of our Fabric Weight Formulations.

It is used to calculate settings for machines of different sizes to produce the same identical fabric

in a different width.

It is used to calculate production capacity per fabric style, per machine for industrial engineering

and production planning purposes.
