Simulation analysis of a FMS during implementation

摘要

Computer simulation is an effective tool for analyzing different aspects of a flexible manufacturing system (FMS) during implementation. Simulation “what-if” analysis can improve productivity, thus resulting in more cost effective systems. A simulation analysis of a totally automated FMS is used to exemplify the types of insights possible. The system is capable of producing 27 different iron and steel cylinder blocks for hydraulic piston pumps which serve a variety of industrial and commercial needs. The system is comprised of 16 work cells, including 10 robots, linked together via 2 non-synchronous carousel conveyor systems. The main objective of the simulation study was to determine the amount of reduction in system operating time possible to produce the required number of pumps, thus reducing the cost per piece. The analysis revealed that approximately 10% of system uptime could be eliminated through a combination of new equipment and modified processing methods.
