Outline of Final Research Achievements

The supply chain problem under stochastic demand was handled as an analytical target. An approximate-dynamic programming was applied, and the sub-optimal solution of supply chain problem was obtained. It was shown that approximate-dynamic programming was an efficient method to optimize the supply chain system under stochastic demand.
The researcher paid attention to the operation availability of the entire system for the reliability of a global supply chain system. By the formula, always maintaining an extra stock between the processes in preparation for the sudden and long stop like the disaster did not show that a big effect was brought. In addition, an synchronous rate of the stop between the adjoining processes and the operation availability of the process unit gave the influence on the operation availability of the entire system by the numerical example.
