The paper presents a cost-efficiency model of a flexible manufacturing system (FMS) in order to analyze and make a tradeoff between flexibility, capacity, and to select a proper system. The efficiency model is based on the time sharing concept, where manufacturing time (machine resources) is allocated to different parts (batches). The allocation is dependent on the complexity and other features of different parts. A simple cost model is included, taking into account different cost factors, such as machine, tool, software, planning costs, and systems features. The model is implemented into a multi-objective programming system to make tradeoffs and analyze different alternatives. The system can be used in an interactive way, so that the decision maker can compare different feasible solutions, or in order to optimize different multi-criteria value functions. Relative performance indicators and different value functions have been included. A numerical example demonstrates the system properties. The model and the interactive system form the basis for understanding decision making on FMS investments as well as for analyzing which techno-economic factors have an impact on the benefits of FMS and company-level decision making.
