【摘要】：柔性能力是企业应对需求波动风险的重要手段,投资提前期长,属于战略决策。考虑了运作层面的生产成本,研究了柔性能力生产成本与专用能力生产成本不同时柔性能力选择及投资决策,并与两种生产成本相同时的决策进行比较分析。将问题构建为两阶段随机规划模型,最优投资决策满足的条件可由卡罗需-库恩-塔克条件给出,并符合多维报童模型。柔性能力投资策略属于阈值策略,当且仅当柔性能力投资成本低于阈值时,对柔性能力投资是最优的。生产成本相同和不同两种情形相比较,后者的最优决策满足条件需要更多需求区域的划分,柔性能力投资成本阈值低于前者,投资条件变得苛刻。最后,通过数值分析对主要结论进行说明和验证,并分析需求波动风险参数对主要结论的影响。
[Abstract]:Flexible ability is an important means for enterprises to deal with the risk of demand fluctuation. The investment lead time is long and belongs to strategic decision. In this paper, the flexible capability selection and investment decision are studied at the same time between the production cost of flexible capacity and the production cost of special capacity, and compared with those of the two kinds of production cost. The problem is constructed as a two-stage stochastic programming model. The conditions of optimal investment decision can be given by Carrion-Kuen-Tucker condition and fit the multi-dimensional newsboy model. The flexible capability investment strategy belongs to the threshold strategy, if and only if the cost of the flexible capacity investment is below the threshold. Compared with the same and different production cost, the optimal decision of the latter needs more areas of demand, and the cost threshold of flexible capacity investment is lower than that of the former. Finally, the main conclusions are explained and verified by numerical analysis, and the influence of risk parameters of demand fluctuation on the main conclusions is analyzed.
