Modeling and simulation for stochastic inventory system based on synthesis coefficient
基于综合系数的随机存储系统建模与仿真

Stochastic inventory system of (s,S) Policy, of which both the demanded quantity and time between demands are random variables, was discussed. Taking stock total cost and rate of shortage as two performance indexes of the system, simulation model was created. The two indexes weighted average, synthesis coefficient was given. Simulation motion graph was designed. When various cost parameters were given, the optimal policy could be selected with computer simulation technique and synthesis coefficient.
