A Simulation Study of an Automotive Foundry Plant Manufacturing Engine Blocks
نویسندگان
چکیده
This paper discusses the initial efforts to implement simulation modeling as a visual management and analysis tool at an automotive foundry plant manufacturing engine blocks. The foundry process was modeled using Pro Model to identify bottlenecks and evaluate machine performance, cycle times and production data (total parts, rejects, throughput, products/hr) essential for efficient production control. Results from the current system identified assembly machine work area as the bottleneck (although utilization was greater than 95% for two assembly machines) resulting in high work-in-process (WIP) inventory level, low resource and machine utilization. Based on these results, optimum numbers were identified through use of scenarios by varying the number of assembly machines and processing time of each machine. In addition to these scenarios, strategies for production control involving buffer sizes were also made.

Holonic Control of an Engine Assembly Plant an Industrial Evaluation
At the beginning of the 1990s, the holonic manufacturing paradigm was proposed (among others) to meet the upcoming challenges in the manufacturing industry. Even though the holonic idea is appealing, its implementation would revolutionize the way manufacturing is done today and thus needs to be thoroughly evaluated before it can be adopted. To this end, an industrial feasibility study for (auto...
