What is Advanced Manufacturing

Systems ? Advanced manufacturing involves the useof technology to improve products and/or processes, with

the relevant technology being described as advanced,

innovative, or cuttingedge.

The rate of technology adoption and the ability to use that

technology to remain competitive and add value define the

advanced manufacturing sector

Different Types Of Advanced

Manufacturing System

Just-In-Time Manufacturing (JIT)

Computer-Integrated Manufacturing (CIM)

Flexible Manufacturing Systems (FMS)

World Class Business Manufacturing Systems(WCBM)


4/25

Just-In-Time Manufacturing:

A Definition a corporate system designed to produce

output within the minimum lead time and at the

lowest total cost by continuously identifying andeliminating all forms of corporate waste andvariance.

a corporate strategy

a philosophy


5/25

Objective of JIT

Produce only the products the customer wants. Produce products only at the rate that the customer

wants them.

Produce with perfect quality

Produce with minimum lead time.

Produce products with only those features thecustomer wants.

Produce with no waste of labor, material orequipment -- every movement must have a purposeso that there is zero idle inventory.

Produce with methods that allow for the

development of people

Just-In-Time Techniques

Inventory Reduction as a Tool forImprovement

Supplier Relationships

Inventory Pull Uniform Plant Loading

Reduced Setup Times

Shop-Floor Layout and Production Cells Total Quality Assurance

7/25

Theoretical Benefits of JIT

Unpleasant surpriseseliminated

Less computerization visual control

Improved quality

WIP reduced

Bettercommunications

Less pressure onreceiving docks and

incoming inspectionareas

Lower costs

Change in attitude

Defects are treasures


8/25

Requirements for JIT

Respond to CustomerRequirements

Integrate all Processes in theManufacturing System

Employee Participation inMeeting Commitments

Use a pull ProductionSystem

Design products forManufacturing

Develop ControllableProduction Processes

Company wideCommitment to education

Eliminate redundancy

Reduce all Inventory

Establish ContinuousImprovement Goals

Have a Defect PreventionProgram

Reduce Setup Times Build Products to

Specification

Computer-Integrated

Manufacturing It was promoted by machine tool manufacturers in

the 1980's and the Society for ManufacturingEngineers (CASA/SME). Quite often it wasmistaken for the concept of a "lights out" factory.


10/25

CIM Includes

CAD/CAM, computer-aided design/computer-aided manufacturing,

CAPP, computer-aided process planning,

CNC, computer numerical control machine tools,

DNC, direct numerical control machine tools, FMS, flexible machining systems,

ASRS, automated storage and retrieval systems,

AGV, automated guided vehicles, use of robotics and automated conveyance,

computerized scheduling and production control, a business system integrated by a common data

base.

The Elementsof CIM


12/25

CIM

Integration of design, manufacture & delivery viacomputer technology

CAD - uses software to create & modify designs

CAM - uses programmable automation inmanufacturing

CAE - links functional design to CAD form design

CAPP - creates processing instructions for CAM

GT- classifies designs to benefit from priorexperience

Flexible Manufacturing

Systems (FMS)An FMS is a reprogrammable manufacturingsystem capable of producing a variety of productsautomatically. Conventional manufacturing

systems have been marked by one of two distinctfeatures: The capability of producing a variety of different

product types, but at a high cost (e.g., job

shops). The capability of producing large volumes of a

product at a lower cost, but very inflexible interms of the product types which can be

produced (e.g., transfer lines).

FMS contd...

An FMS is designed to provide both ofthese features.

Programmable machine tools Controlled by common computer network Combines flexibility with efficiency

Reduces setup & queue times

Classification of FMS-related

Problems Strategic analysis and economic justification,

which provides long-range, strategic business plans.

Facility design, in which strategic business plans are

integrated into a specific facility design to accomplishlong-term managerial objectives.

Intermediate-range planning, whichencompasses decisions related to master production

scheduling and deals with a planning horizon fromseveral days to several months in duration.

Dynamic operations planning, which isconcerned with the dynamic, minute-to-minute

operations of FMS.


19/25

FMS Problems Part type selection (Askin) - selecting parts that will be

produced in the FMS over some relatively long planninghorizon.

Part selection (Stecke) - from the set of parts that havecurrent production requirements and have been selected for

processing in the FMS, select a subset for immediate andsimultaneous processing.

Machine grouping (Stecke) - partition machines intogroups where each machine in a group can perform the sameset of operations.

Loading (Stecke) - allocate the operations and required toolsof the selected part types among the machine groups.

Control - provide instructions for, and monitor theequipment in the FMS so that the production goals identified

by the above problems are met.
