PRODUCTION AND OPERATIONS TRANSACTION PROCESSING SYSTEMS

CHAPTER 12.2

 

Production Control: Purchasing, Scheduling, Inventory, Shipping

 Purchasing Management Systems keep track of vendors, supplies ordered, received, stored, and back-orders

 Job scheduling systems decide when to initiate production of specific items based on supply and customer demand

 Inventory control systems track current supplies of inventory and match this against anticipated orders from customers

 Shipping management systems track customer orders from receipt to final chipping

 The modern day bar code technology enormously increases efficiency of the entire production process

 

Tradition 1-D BAR CODES CONTAIN A SINGLE LINE OF INFORMATION

2-D BAR CODES HAVE MULTIPLE LINES UP TO 1,800 CHARACTERS STORED ON A TWO INCH SQUARE PATCH

 

 

Special laser readers can read the information scanned through a single pass

 

Dock employees wearing a wrist mounted laser reader can instantly tell who manufactured the incoming supplies, the part numbers, cost and location to be stored

 

The result is error reduction-avoid thousands of errors when filling orders for liquor stores

 

Process Control

 

Process control system which monitors and controls either the physical machines on the shop floor or the work being done at a work station desktop in offices

 

Quality control measures the deviation of products from predefined standards that set off alarms

  

Computer Aided Design and Computer Aided Manufacturing (CAD/CAM)

 

Computer Aided Design (CAD) tools are used by engineers to design, draw and create products. Usually a powerful UNIX station

 

Engineers feed the output into Computer Aided Manufacturing systems that control shop floor machines. In this way the product cycle (length of time from design to manufacturing) can be greatly speeded up and increased productivity

 

Manufacturing Resources Planning (MRP)

 

Manufacturing Resource Planning (MRP) systems integrate the CAD/CAM functions into a single software/hardware system

 

MRP system coordinates materials management, with process control, inventory control, scheduling and quality control . No more work flow interruptions and deviations from production standards fall reducing the amount of raw materials consumed.

 

Electronic Data Interchange(EDI)

 

Electronic Data Interchange (EDI) provides telecommunication to link suppliers, manufacturers, and customers. Helps to reduce paperwork.
