PRODUCTION INFORMATION

SYSTEMS


2/23

Operational information system

Produce Routine, repetitive, descriptive, expected, objected data past activities.

They are detailed , highly structured, accurate internal sources .

Its tedious work to the employees

APP INFO SYSTEMS TECHNOLOGY TO OPERATION INFO SYSYTEMS

Provided managers with more advantage

Run faster and less personal

Reduce cost, increases speed, accuracy, increases customer service ,

more data for decision making .

PRODUCTION INFORMATION SYSYTEMS

Production system are designed to produce goods and service to meet marketing

system .

Includes continuous flow of production, mass production, job order production.

Production information system helps in decision making for operation, allocation,

planning of production system.

some information systems support production functions eg financial system which helps

in purchasing, account payable, inventory, order entry, account receivable, payroll.

OPERATIONAL INFORMATION SYSTEM USED

IN PRODUCTION

1. Purchasing system.

2. Receiving system.

3. Quality control system.

4. Shipping system.

5. Cost accounting system.

6. Inventory control system.

7. Automated material handling system.

8. Computer aided design and manufacturing system.

9. Image management systems.

10.Shop-floor scheduling systems.

11.Mass customization and agile manufacturing systems.

PURCHASING SYSTEMS

To produce goods and service u must have right quantity of raw materials

and production supplies .

Procure raw materials at low cost and deliver at right time.

Production system has to maintain data of raw materials and purchase parts

used in production.

It has to maintain information about vendors and price quotations .

Maintain record of goods that are already in order .

Open order report

it helps in controlling exceeding budget allocation

RECEIVING SYSTEMS

When shipment of purchased goods

supplied or receive it must be

Opened

Inspected

Verified against purchase order

Delivery time

And status passed to inventoryaccount payable Production dept.


9/23

QUALITY CONTROL SYSTEM

It provides information about the status of production goods as

they move from raw material state , through goods in process, to

finished goods.

QCS ensures the raw materials or purchased parts forproduction meets the standard.

Monitor during production cycle .

Data are collected using shop-floor data collection system.

Shop-floor data obtained from counters , assembly line data

entry, process control sensors.

Product development and design system can use quality controlinformation to determine realistic specification for a product

under development .

Purchasing system uses to obtain raw materials, purchasedparts and production supplies.

Help in identify vendors , production machinery, worker.

Includes Customer complaint to production system to improvequality.

Two approaches are used

1.just in time system2.total quality control.(prevention)


12/23

SHIPPING SYSTEMS

Finished good are placed in inventory or shipped to

customers

Records and documents has to be maintained

E.g. shipping report , packing slip

If not it affects the inventory and account receivable

system.


13/23

COST ACCOUNTING SYSTEM

Financial system collects and report information about resources used in the

production process .

It helps managers to obtain cost involved in production of product and

service .

Cost accounting system monitors 3 resources

1. HUMAN RESOURCES PAYROLL (cost, time)

2.MATERIALS inventory level, use , location, specification. (BOM)

3.EQUIPMENT AND FACILITIES- what equipment & facility, what length of

time on what product and service and at what cost .

These provides information tojob costing system.


14/23

INVENTORY CONTROL SYSTEMS

Management and control of raw materials, goods in process, finished goods areimportant for production system.

Careful managing & controlling inventories provides considerable savings.

It uses information from shipping, receiving systems, purchasing systems andorder entry system.

Maintaining inventories at proper level eliminates production shutdown from lackof raw materials and lost sales from lack of finished goods.

ECONOMIC ORDER QUANTITY(EOQ)

RECODER POINT SYSTEM

LEAD TIME

SAFTEY STOCK

IT IS BALANCE BETWEEN PROCUREMENT COST AND CARRYING COST.

16/23

AUTOMATED MATERIAL HANDLING SYSTEMS

Monitoring inventory from time it is received to time itshipped is important .

AMH tracks, control the movement of raw materials, work

in process and finished goods from receiving to shipping

AHM software combines with various material handlingequipment such as conveyors, pick and place robots and

automated guided vehicles.


17/23

COMPUTER AIDED DESIGN AND MANUFACTURING

SYSTEMS

Software are helps product engineers to design new product and improve old

products.

CAD/CAM

CAD Computer aided design

Two categories

1. It helps mechanical engineers and architects to construct and modify complex

design, blueprints . E.g. auto cad

2.It helps electrical engineers to design quickly and easily and draft final

electrical circuits. It helps engineers with simulation capabilities.

It ensure product will be reliable, free from failure.

It helps to bring products to market faster and saves money.


18/23

CAM COMPUTER AIDED MANUFACTURING

CAM Software converts CAD drawings into finished products

with little human intervention.

e.g. A bolt designed using CAM software reads design and

instructs lathe machine to a bolt with specified parameters in

CAD drawing .

CAD/CAM are enhance by CAE,CAT,CAPP,CAI


19/23

IMAGE MANAGEMENT SYSTEMS

Engineering and architectural drawings are difficult to store and

retrieve in hard copy forms .

One design part may be useful for another design .

IMAGE MANAGEMENT SYSTEM are designed to manage and

retrieval of engineering and architectural drawings using optical

disk storage media.

The change made are also distributed to the users using LAN


20/23

MATERIAL SELECTION SYSTEMS

Many programs are available that aid the engineers in choosing

materials for product under deign .

These programs are called MATERIAL SELECTION PROGAMS(MPS)

It helps in selecting the best materials to account of stress,

heat, humidity, and other conditions.

Sawyer and pecht(1986) note metal category alone, engineersmay chose 100000 materials with 80 properties.


21/23

SHOP-FLOOR SCHEDULING SYSTEMS

A operational task for a supervisor is to schedule production jobs.

It includes scheduling time, building and rooms, tools and equipment,

inventory, personnel.

Setup time- time takes to get ready for the production run.

Down time- time it takes to return to original state, tool requirement,

equipment requirement and operational requirement.

It is done by GANTT CHART

Main advantage is optimal use of resources.

When problem occurs such as strike of operators, late shipment of raw

materials, equipment failure supervisor uses software to alter the schedule .
