Integration of Network Analysis Systems with MRP in a Make-to- Order Manufacturing Environment.
MetadataShow full item record
The unique requirements in a make-to-order manufacturing environment dealing with long lead time products cannot be satisfied by either MRP or Network Analysis systems alone, but necessitate a combination of features of both. MRP is capable of handling manufacturing tasks in great detail, but it is not designed to accomodate non-material related tasks. Further, schedules generated by MRP do not reflect the fiexibility desired in varying amounts in every manufacturing contract. Network Analysis, othenvise known as Critical Path, can handle activities of any nature. It provides flexibility in scheduling activity and caters for resource and cash flow scheduling and other features usually not present in MRP systems. A combined MRP/Network analysis system for use in a make-to-order manufacturing environment is described and demonstrates the potential benefits on purchasing and manufacturing orders compared to ones generated by traditional MRP systems. Portions of a computer program being developed to implement a combined MRP/Network analysis system are included.
