Industrial Engineering (IE)

Industrial engineering is a branch of engineering which deals with the optimization of complex processes, systems or organizations. Indusial engineers work to eliminate waste of time, money, materials, manpower, machine, energy and other resources that do not generate value.

6

Activities of Industrial Engineering

Selection of processes and assembling methods. Selection and design of tools and equipment. Design of facilities including plant location, layout of building, machine and

equipment. Design and installation of value engineering and analysis system. Operation Performance evaluation. Supplier selection and evaluation.

7

Work study

Work study is a systematic technique of method analysis work measurement and setting of time standard that can be ensure the highest productivity by the optimum use of man power, equipment and material.

 

8

To analyses the present method of doing a job. To measure the work content of a job by measuring the time

required to do the job for a qualified. To increase the productivity by ensuring the best possible use of

human, machine and material resources. To improve operational efficiency.

Objects of Work Study

9

Benefits of work study

Increased productivity and operational efficiency Reduced manufacturing costs Improved work place layout Better manpower planning and capacity planning Fair wages to employees Better working conditions to employees Improved work flow Reduced material handling costs

10

Motion study

Motion study is the study of the body motions used in performing an operation, toimprove the operation by eliminating unnecessary motions, simplifying necessarymotions, and then establishing the most favorable motion sequence for maximumefficiency.

11

Time Study

Time study is a work measurement technique for recording the time of performing a certain specific job or its element carried out under specific condition and for

analyzing the data so as to obtain the time necessary for an operator to carry out at a defined rate of performance.

Time study is a method of direct observation. A trained observer watches the job and records data as the job is being performed over a number of cycles.

12

Objectives of time study

To identify the efficiency and productivity of the company To set the standard time for each job. To set daily, monthly production target. To identify the efficiency of the worker. To evaluate a process cycle. To identify the qualified worker for the advanced process. To set basic time at a standard performance.

13

Time Study Tools  To do time study you need to arrange following tools A stop watch Time study format One pen or pencil Time Study board

14

The importance and uses of stop watch time study

Determining schedules and planning work Determining standard costs and as an aid in preparing budgets Estimating the costs of a product before manufacturing it. Determining time standards to be used as a basis for labor cost control. Helps to know the Labor productivity, Labor efficiency, Labor Performance Helps to improve the process of operation.

15

Operation breakdown the job in to elements

Elements should be easily identified, with definite beginnings and endings so that, once established. They can be repeatedly recognized. The point at which one element ends and another begins is called break point. Breakpoints must be decided by the work study officer when he divides the work cycle into elements.

All breakpoints can be recognized by a sound or by a change of direction of a hand or arm.

Elements should be as short as can be conveniently timed by a trained observer, but should not be less than 0.10 minutes and more than 0.50 minutes.

Manual elements should be separated from machine elements for future use as synthetic data.

Short elements should be next to long elements.

16

Basic Time

The basic time for the operation is found by applying concept of rating to relate theobserved to that of a standard place of working.

Types of allowances

Relaxation Allowances Personal needs Basic fatigue

Various other types of allowance are Policy allowance Special allowance

Results & Discussion

26

Conclusion Industrial engineering is an important and essential part of any Garments

Industry. One of the aims of any production system is to make total production time as minimum as possible. This automatically reduces inventory cost to a minimum. Sub-assembly system provides many opportunities to economies on temporary storage and transportation space and time. No definite answer can be given as to which is the best, as it depends on garment style, specifications, machinery and manpower and manufacturing policies.
