Summary of Accomplishments and Activities

The goal of this integrated production management (IPM) research was to develop a 'maximal' production management methodology that takes advantage of the major sources of flexibility in shop floor decision making, for example choice of process plan, machine used to create feature, sequence at each machine, inventory created, shortage accepted, subcontract awarded, or lot size.

A major undertaking of the project at OSU was the significant advancement of the fast simulation approach. Duse (1994) developed new modeling abstractions, recursive relationships, and conceptual frameworks for generating fast simulation models of many common manufacturing topologies such as merge, split, assembly, parallel server workstation and unreliable server. In Duse’s study, a new hybrid approach that combines the recursion based and event-scheduling based models in a single simulation model was investigated. Duse developed guidelines for partitioning a simulation model into fast simulation and event-scheduling segments.

Sreenivasan (1996) developed a new modeling abstraction of “pulling customers into the network as and when needed” an showed that this new modeling abstraction could provide the much needed basis for developing pure fast simulation models of typical production system that was a combination of many common manufacturing topologies such as merge, split, assembly, parallel server workstation and finite buffers. Based on this abstraction, Sreenivasan (1996) developed a fast simulation methodological framework that enables us to create a library of software modules or building blocks that can be used to build fast simulation models of larger systems.
