Abstract : a scheduling problem on the single machine with fuzzy processing time is studied 文摘:研究单机模糊加工时间下确定最迟开工时间的调度问题。
To better demonstrate the relations among the indexes , they are treated by fuzzy processing method and their weights are calculated 计算各个指标相对重要程度,即确定各指标的权重。
By considering both fuzzy processing time and fuzzy due date as well as specific operator of the workpiece with alternative machines , a fuzzy job shop scheduling problem with alternative machines was studied 摘要在车间实际加工中,工件的加工时间和交货期是一个模糊数,而且工件的某道工序有多台机器可供选择。
Through analyzing the model by applying fuzzy mathematics extension principles and the properties of jobs with fuzzy processing times , the optimal solutions of the problem are presented under some special cases , and a necessary condition of optimal solution is given under the general case 通过模糊数学知识对模型进行分析,对于特殊情况给出了问题的最优解,对于一般情况给出了一个最优解的必要条件。
Take the laser diode as the photoelectric detector ' s lamp - house , the optical system forms images of the sign , the double photoconductive resistance detects the excursion of the sign , a / d converter finishes a / d convert , the data is fuzzy processed by micro computer 光电探头采用激光二极管作为光源,光学系统完成标志的成像,双光敏电阻检测标志线的偏移, a / d转换器完成偏移信号的模数转换,数据由微机进行模糊处理。
