【摘要】 作业计划与调度教学实验系统是为实现我校“高素质、高层次、多样化、创新性”的人才培养目标开发的百门精品课程建设项目中的一部分,其内容是:配合“现代制造技术”课程建设,开发出一套研究型教学实验系统,目的是发挥学生的个性、潜能,加强对学生的创造性与工程能力的培养。制造车间作业计划就是确定工件的加工顺序,确定机器加工每个工件的开始时间和完成时间。调度就是在满足作业计划所规定的约束条件下对操作的排序。仿真就是通过对系统模型的实验去研究一个真实系统。 论文首先对制造车间作业计划与调度及其仿真技术进行了研究,构建了一个研究型作业计划与调度教学实验系统,在以下几方面开展了深入研究:1.结合研究型教学实验系统的需求和特点,建立作业计划与调度教学实验系统的总体结构。教学实验系统由信息输入模块、训练题库、车间信息库、制造资源库、调度算法库、结果输出/分析模块组成。2.设计一组训练题库,对学生进行建模与仿真的基本技能训练。采用QUEST软件提供的制造资源进行二次开发和组合,使学生可以根据给定的零件信息选择制造资源、设计制造系统布局并创建制造系统模型。3.在分析目前已有的各种先进算法的基础上,结合教学实验的特点,采用SCL语言实现典型的车间调度算法:流水排序法和能动作业计划的调度算法。并对作业计划与调度进行仿真,输出仿真结果。4.选择我校CIMS教学系统作为真实车间,对仿真结果进行验证。更多还原

【Abstract】 The experimental teaching system of the job planning and scheduling is a part of the construction for one hundred well-chosen courses to realize the training objective of high quality, high level, diversity, and innovation in Tsinghua University. Its content is to develop a set of research type experimental teaching system to cooperate with the construction of the Modern Manufacturing Technology course. Its objective is to exert the potential and personality of the students, and enhance their creative and engineering abilities. The job planning in a manufacturing workshop is to fix on the machining sequence, the starting time and finishing time for each part. The schedule is the operating sequence under the situation of satisfying the constraint conditions of task plan. The Simulation is to study a real system by means of the experimentation of the systematic model. In this paper, the job planning、 scheduling and simulation technique in a manufacturing workshop are studied at first. A research type experimental teaching system of job planning and scheduling is built. Make a thorough study in following respect: 1. The simulation software of discrete sequence QUEST is the developing tool. The teaching system consists of information input module, training library, information library of the workshop, manufacturing source library, schedule algorithm library and the result output/analysis module.2. Design a group of training library, and train the fundamental ability of modeling and simulation of the students. Adopt manufacturing source library of QUEST, carry out re-develop and assemble. According to known part information, student can select manufacturing source、lay out a manufacturing system、 create a model of manufacturing system.3.The SCL language is adopted based on the analysis of current advanced algorithms to realize a typical workshop schedule algorithm: pipelining sort method and motile task plan, carry out simulate for job planning and control, out put the simulation <WP=4>result.4. The CIMS teaching system in Tsinghua University is selected, and the simulation result is manifested更多还原
