| Low risk and high profit is the final destination which the corporations pursuit in the processes of corporation management decisions. But the indeterminacy of market and the limitation of resources et al. will make it difficult to reach both low risk and high profit at the same time for the corporations.This paper will study the methods describing risk of the ability decision in FMS (Flexible Manufacturing System) and their effect on ability decision. Based on the present theoretical research of FMS, at first, we give a general introduction on the origin, development, and its function in production industry, and analyze the importance of risk problem from point view of corporation decision and management. Then, we constructed the ECSP (equipment changeover and selection problem) model based on the example of the extension and adjustment in PCB (printed circuit board) lines using the SMT (surface mounted technology). By applying the price determined method in option pricing in financial theory together with the consideration of risk in confinement to ECSP, we described the risk problem in the processes of management decision. We solved the SMT production lines ability extended model which described the risk problem in the condition of random need by using gene algorithm. At last, using computer simulation, we described the feasibility of gene algorithm in this model and their effects on decision ability. |
