An aggregate capacity analysis model for flexible manufacturing systems

摘要

Many manufacturing systems often need to analyze whether there is sufficient capacity to perform several technologically different operations for their current set of production orders. To perform such capacity analysis, the concept of an "operation type" is introduced. Based on the "operation types" a model is presented, which can evaluate the capacity of the various manufacturing capabilities of the system. A method for sensitivity analysis is also developed which provides information about the availability of capacity when production requirements and/or machine capacities change. The presented method can be a useful tool for production planning, for tooling and loading considerations in flexible manufacturing systems, and it can also assist in on-line production control.
