Considering Stochastic Production Systems (SPS) consisted of multiple manufacturing cells interconnected with batch Material Handling System (MHS), this project deals with the Resource Allocation Problem (RAP), i.e. under the condition of stochastic arrivals of the orders, minimizing the total amount of investment subject to constraints of both average throughput and make-span of products. The content includes: setting up the queueing network models of flexible manufacturing cells with Dual Resource Constriants (DRC) in which robots are used to load/ unload the parts; building up the layered queueing networks of SPS consisted of multiple manufacturing cells interconnected with batch MHS; putting forward to algorithm to solve RAP with DRC; proposing a decomposition-coordination solution scheme to solve RAP of SPS. Creativities of this project lie in the following, open queueing network models with finite buffers are first extended to describe the beheaviors of manufacturing cells with DRC, state-dependent batch transportation and routing choices; A problem-features based branch-and-bound algorithm is put forward by means of decomposing the complicated problem into two interconnected sub-problems, one is a Capacity Configuration Problem (CCP) and the other a Buffer Allocation Problem (BAP), an iterative framework is presented between them, thus enhancing the efficiency of searching the optimal solution to RAP of a manufacturing cell with DRC; a decomposition- coordination solution scheme is then employed to solve RAP of SPS optimally. The output of this project can provide the order-driven manufacturers with scientific methodology for the resource allocation, which require to take capacity expansion or to build up a new factory.
