Abstract: To study the efficiency evaluation and resource allocation of parallel production system, the efficiency of service departments was calculated and the principle of allocation about shared resources in DEA parallel system, or the mechanism satisfying the maximization of overall efficiency, was explored. This is an indepth analysis and explanation of how to allocate shared resources in parallel production system with the methods of DEA. The results indicate that: firstly, when maximizing overall efficiency, the overall efficiency score is a convex combination of efficiency scores of two sub units under the optimal allocation coefficient; secondly, when maximizing overall efficiency, the sub unit whose efficiency score is equal to the overall efficiency reaches its own maximum efficiency. At this time, the efficient sub unit by DEA is allocated all of the shared resources, while the inefficient one gets nothing.
