Stochastic dynamic job shop scheduling problem with consideration of sequence-dependent setup times are among the most difficult classes of scheduling problems. This paper assesses the performance of nine dispatching rules in such shop from makespan, mean flow time, maximum flow time, mean tardiness, maximum tardiness, number of tardy jobs, total setups and mean setup time performance measures viewpoint. A discrete event simulation model of a stochastic dynamic job shop manufacturing system is developed for investigation purpose. Nine dispatching rules identified from literature are incorporated in the simulation model. The simulation experiments are conducted under due date tightness factor of 3, shop utilization percentage of 90 % and setup times less than processing times. Results indicate that shortest setup time (SIMSET) rule provides the best performance for mean flow time and number of tardy jobs measures. The job with similar setup and modified earliest due date (JMEDD) rule provides the best performance for makespan, maximum flow time, mean tardiness, maximum tardiness, total setups and mean setup time measures.

For increasing the overall performance of modern manufacturing systems, effective integration of process planning and scheduling functions has been an important area of consideration among researchers. Owing to the complexity of handling process planning and scheduling simultaneously, most of the research work has been limited to solving the integrated process planning and scheduling (IPPS) problem for a single objective function. As there are many conflicting objectives when dealing with process planning and scheduling, real world problems cannot be fully captured considering only a single objective for optimization. Therefore considering multi-objective IPPS (MOIPPS) problem is inevitable. Unfortunately, only a handful of research papers are available on solving MOIPPS problem. In this paper, an optimization algorithm for solving MOIPPS problem is presented. The proposed algorithm uses a set of dispatching rules coupled with priority assignment to optimize the IPPS problem for various objectives like makespan, total machine load, total tardiness, etc. A fixed sized external archive coupled with a crowding distance mechanism is used to store and maintain the non-dominated solutions. To compare the results with other algorithms, a C-matric based method has been used. Instances from four recent papers have been solved to demonstrate the effectiveness of the proposed algorithm. The experimental results show that the proposed method is an efficient approach for solving the MOIPPS problem.

介绍了一种新的规则自提取和简化的模糊模型算法,该算法由3个步骤组成:首先,通过构造一个模糊软划分判别准则对输入输出空间进行模糊划分,得到最佳分类数,从而得到了最佳的规则数;其次,根据最佳规则数和神经网络来构造初始的模糊模型;第三,通过运用模糊相似分析法,可以得到计算2个模糊集相似度的方程,从而根据事先确定的阈值来合并相似的模糊集。这样就得到了一个既满足对精度的要求又简单且具有可解释性的模糊系统。最后,用该算法对我国全要素生产力进行了模糊规则的提取。

针对目前区间灰数的表征和运算过程中存在着较为严重的问题,即:运算结果对灰数的灰度进行不必要的放大,造成信息的严重失真,笔者定义了标准区间灰数与第一和第二标准区间灰数的概念,分析了第一和第二标准区间灰数之间的关系,进一步设计了普通区间灰数与标准区间灰数之间的转换规则,提供了标准区间灰数之间的比较与运算法则,较好地解决了区间灰数之间的大小比较与运算问题。最后,将这一研究成果应用于基于区间数的GM (1, 1)模型预测问题,取得了良好的效果。
