For computerization of manufacturing engineering different computerized systems are used for process planning, material and manufacturing resources planning
, and other functions [1, 4-7].
The successor of MRP is called Manufacturing Resources Planning
(MRP II), which acts as an extension to MRP and largely deals with most of its problems.
Spun out from the manufacturing resources planning
(MRP) systems that gained popularity in the 1980s, today's ERPs span numerous areas of an organization including manufacturing, engineering, finance, customer service, project management, human resources, and accounting.
However, "manufacturing resources planning
" (MRP II) largely deals with that problem.
At that time, scheduling of maintenance operations was based on a Manufacturing Resources Planning
II (MRP-II) system that used a push system to load the resources at the Center based on anticipated customer demand.
Essentially, optimization takes the data from supply chain, manufacturing resources planning
, manufacturing execution systems and ERP systems and sifts through thousands or even millions of variables to determine optimum manufacturing and supplier operations.
Rasul adds that the company is now in the process of selecting a manufacturing resources planning
software vendor for its new $350 million North American plant, which begins construction in 2001.
It all started with manufacturing resources planning
, which aimed to change the manufacturing process.
Pilkington moved to a manufacturing resources planning
(MRP II) system, choosing an integrated suite of applications that includes forecasting, capacity planning, materials requirements planning (MRP), order processing, scheduling, and inventory control.
Currently what tends to be used varies from manual methods (for low complexity and mix) through spreadsheets to periodic control, MRP and manufacturing resources planning
(MRPII), order process time (OPT) and finite capacity planners (for high complexity and product mix).
There are at least five levels of sophistication in CIM: parts counting, which watches machine cycle efficiency; process monitoring, which collects machine operating data for preventive maintenance; statistical process-control (SPC) analysis, which crunches key variables into X-bar and R charts; auxiliary-equipment monitoring, which refines machine data and raises efficiency; and integration of shop-floor data with office business systems, such as materials requirements planning (MRP) or manufacturing resources planning
Recent years have seen an increased level of interest in the ability of organizations to improve their manufacturing and service competitiveness by implementing such techniques as Just-In-Time (JIT) inventory systems and Manufacturing Resources Planning
(MRPII), the enhanced version of Materials Requirements Planning (Capitals) (MRP).
