Analysis and research of system configuration and economic evaluation of reconfigurable manufacturing system

Reconfigurable manufacturing system (RMS) is intelligent and advanced manufacturing system, RMS is able to change production functionality and capacity to meet with market demands by adjusting system configuration or adding new components. The object of RMS is able to achieve optimal economic cost within the overall life cycle, therefore, it is very important to study the system configuration and technology of economic cost evaluation, and they are very important system-level enabling technologies of RMS. A systematic design structure model of RMS is presented to show the condition of configuration and economic evaluation. A RMS configuration model is presented, and the configuration model performance is analyzed from reliability, convertibility, quality, productivity and material transmission ratio by using system engineering theory, Boolean algebra and so on. A RMS production cost model is analyzed, a mathematics model is presented to calculate the production cost and a system investment evaluation cost model is presented based on real option analysis theory, case study illustrates the effectivity of the proposed model and technology.
