This article presents a methodology for the design of a modular semi-automated reconfigurable assembly system using component-based simulation and life cycle cost analysis. To ensure that an assembly system is appropriately designed, system measurement schemes should be established for determining and understanding design effectiveness. Measurements can be classed into two categories: cost and performance. Understanding manufacturing costs is the first step towards increasing profits. The authors are developing an analysis tool that integrates Overall Equipment Efficiency (OEE), Cost of Ownership (COO), and other analysis methods to improve the design of flexible, modular reconfigurable assembly systems. The development is based on selected industrial standards and the authors’ own experience in modular assembly system design and simulation. The developed TCO (Total Cost of Ownership) methodology is useful in system supplier and end-user communication, helps in trade-off analysis of the system concepts and improves the system specification.

The development was carried out in an Eureka Factory E-Race project. www.e-race.info. Topic of presentation covers one VTT work in economic analysis and lifecycle modelling with particular emphasis on system reconfigurability. E-race project has finished, in Finland March 2006.
Work shall be enchanced in a new, running project MS2Value.
