碩士 === 國立屏東科技大學 === 工業管理系 === 92 === This study constructs three inventory models ((Q,R), (s,S) and (T,W)) with fixed lead time and equal cycle time for supply chain systems within distribution center, taking discrete demand into account as inventory patterns. By using goodness-of-fit approach to test historical sales performance, the method of moment estimator or so-called two levels of Monte Carlo simulation is introduced to predict vital parameters and to forecast future demands as well. Optimal decision variables that maximize the total expected profit are also found through the numerical analysis algorithm. In addition, 50 times of simulations are generated to compare the total expected profit with these three models to conduct suitable statistical experiments on the aspects of mean-variance dominance and stochastic dominance rules. Numerical examples are given to validate the results of the inventory variations in the proposed model.
