摘要: 针对多目标、多产品、多计划期和需求、生产费用、生产能力等参数不确定的综合生产计划问题进行了研究。引入区间数描述生产计划问题中存在的不确定性,建立了以生产成本最小和设备利用率最大为优化目标的目标规划模型。为求解模型,运用区间规划理论和基于区间序关系的可能度定义,实现了区间目标规划模型的清晰等价转换,并采用Lingo软件完成模型求解。该方法解决了传统不确定优化方法在获取概率分布和模糊隶属度函数较为困难的不足,能根据决策者的偏好以交互方式分析出不同置信水平对目标的影响,为决策者在不确定环境下进行生产计划决策提供理论依据。最后,通过算例说明方法的有效性和灵活性。

Abstract: A multi-objective, multi-period and multi-product aggregate production planning (APP) problem with uncertain demand and uncertain parameters, such as operating cost, production capacity and so on, is studied. An interval goal programming model is developed through introducing interval numbers to represent uncertainties in the APP problem, in which two objectives are taken into consideration, one to minimize the total production cost and the other to maximize machine utilization rate. To solve the uncertain model, the theory of interval programming and the possibility definition based on interval ordinal relation are adopted to transform the uncertain model into its equivalent crisp one, and Lingo software is used to solve the model. The approach overcomes the deficiency of traditional uncertain optimization methods in obtaining precise probability distributions and fuzzy membership functions. In addition, the approach is able to interactively analyze impacts of different confidence levels on the objective function according to the decision maker's preference. Theoretical basis is provided for decision makers to make a rational production plan in uncertain environment. Finally, an industrial example is used to illustrate the validity and flexibility of the proposed method.
