Abstract

In this paper, a new mathematical programming model is proposed for a partial flexible job shop scheduling problem with an integrated solution approach. The purpose of this model is the assignment of production operations to machines with the goal of simultaneously minimizing operating costs and penalties. These penalties include delayed delivery, deviation from a fixed time point for preventive maintenance, and deviation from the priorities of each machine. Considering the priorities for machines in partial flexible job shop scheduling problems can be a contribution in closer to the reality of production systems. For validation and evaluation of the effectiveness of the model, several numerical examples are solved by using the Baron solver in GAMS. Sensitivity analysis is performed for the model parameters. The results further indicate the relationship between scheduling according to priorities of each machine and production scheduling.
考虑预防性维护和优先级的部分柔性作业车间调度
针对一类局部柔性作业车间调度问题,提出了一种新的数学规划模型。该模型的目的是将生产作业分配给机器,同时以最小化操作成本和处罚为目标。这些惩罚包括延迟交付,偏离预防性维护的固定时间点,以及偏离每台机器的优先级。考虑局部柔性作业车间中机器的优先级问题,可以为更接近生产系统的现实做出贡献。为了验证和评价模型的有效性,利用GAMS中的Baron求解器对几个数值算例进行了求解。对模型参数进行了敏感性分析。结果进一步表明了各机器按优先级调度与生产调度之间的关系。
