摘要: 研究了敏捷制造车间(AMW)中的最优递阶随机生产计划与控制问题.首先根据实际 需要建立关联方程有延迟的车间生产的随机非线性规划模型,即一种求解动态优化问题的静态 优化模型.为求解方便将其转化成确定非线性规划模型并通过引进约束进一步转化成线性规划 模型.然后,提出分别用卡马卡算法和基于卡马卡算法的关联预测法进行求解,并编制了相应软 件.算例研究表明所提方法是非常有效的.Abstract: The paper explores the problem of optimal hierarchical stochastic production planning and control in agile manufacturing workshops (AMW). A stochastic nonlinear programming model of production with delay interaction (which is a static optimization model to solve the dynamic optimization problem) is built up and transformed into a deterministic nonlinear programming model and further into a linear programming model by adding constraints. Then, a Karmarkar's algorithm and an interaction/prediction algorithm are used to solve the model, and the corresponding programs have been written. Through hierarchical stochastic production planning examples, the Karmarkar's algorithm, interaction/prediction algorithm and linear programming method in Matlab are compared with, thus showing that the proposed approaches are very suitable for optimally decomposing AMW's random product demand plans into short-term stochastic plans to be executed by FMS in AMW, especially for the case where workpieces are transferred between FMS through a shop storage with a delay of a production period.
