Purchasing Strategy of Large Scientific Engineering Manufacturers Under the Condition of Risk

摘要:

研究风险条件下大科学工程制造商的采购策略，讨论需求和供应的不确定性对制造商最优采购决策的影响。分别在需求不确定、供应不确定、需求和供应同时不确定3种情况下得到制造商最优采购量的隐形表达式，假设需求和供应服从均匀分布，计算3种情况下最优订货量的显性表达式，对最优订货量进行比较静态分析，并将3种情况下的最优采购量和最优利润进行对比。最后，通过数值分析，验证该模型的有效性。

Abstract:

This paper studies the purchasing strategies of large scientific engineering manufacturers under the condition of risk, and discusses the influence of uncertainty of demand and supply on the optimal purchasing decision of manufacturers. Under the conditions of uncertain demand, uncertain supply, uncertain demand and supply simultaneously, the invisible expression of optimal purchasing quantity of manufacturer is obtained, assuming that the demand and supply functions are uniformly distributed. The explicit expression of the optimal order quantity is calculated in three cases, the optimal order quantity is analyzed statically, and the optimal purchase quantity and the optimal profit are compared. Finally, the validity of the model is verified by numerical analysis.
