In addition, we represent the variance of the process as a function of investment, as proposed by Hong and Hayya (1993), to decrease the number of defective items. Our models determine the optimal production lot-size, the optimal levels of investments, and the optimal levels of backorders that minimize the sum of inventory and quality-related costs.

另外，本研究并考虑藉由投资来降低制程的变异，其中利用Hong 等人(1993)所提出制程变异之投资函数，纳入总生产成本模式中考量，即投资后的制程变异为制程改善后所能降低的制程变异水准加上目前生产系统之最大变异水准与最低变异水准之差的指数分配关系，如此不仅能降低变异并提升制程能力指标，亦能让管理者利用本模式来比较不同制程改善的成本差异，推导出最佳生产批量、缺货量和投资成本，以提供存货管理者对生产决策之参考依据。

During the calculation the results got by quintic spline kernel was the best so it was chosen as the proper kernel for the SPH simulation. By comparison of the simulation results got by SPH and finite volume method, it was proved that the buffer cells method proposed in the SPH simulation to implement the Dirichlet boundary conditions was accurate, and this is of great importance for the simulation of flows pass a pipe. At last, the SPH method was improved to simulate the liquid-solid two phase flows and the results show that this method was appropriate for the simulation of flows containing viscous fluid and macroscopic solid components. Now the two methods are both able to predict the continuum flows and rarefied flows severally, but the hybrid program still has some aspects to be improved.
