One of the main critical problems in manufacturing system domains is the production scheduling process, because an agile and reactive production planning and scheduling system is essential in manufacturing. The production scheduling process is a complex problem in which finding a suitable production scheduling can greatly increase the effectiveness of highly flexible production processes. Nevertheless, this high flexibility makes the production scheduling and acquisition of relevant data quite complicated. Therefore, there is a strong demand for a universal and flexible tool for production scheduling capable of increasing the utilization of resources and that supports a decision-making process for the selection of production orders. In this paper, a flexible and adaptive scheduling tool (FAST) to develop an adaptable, fault-tolerant, and scalable scheduling system for a manufacturing environment is presented. This approach is based on multiagent systems (MAS), which provide a natural way to solve problems in domains of this kind. 相似文献

Computer-integrated manufacturing (CIM) is the harmonious connection, integration, and interoperation of automation equipment within a manufacturing facility. In a semiconductor wafer fab, this includes integration of the processing equipment with all of the supporting systems for product and process specification, production planning and scheduling, and material handling and tracking. Traditionally, CIM systems have been characterized as monolithic mainframe-based systems and/or inflexible islands of automation with limited interoperability. Today's manufacturing demands fully integrated dynamic systems which directly support the concepts of lean, flexible and agile manufacturing to high quality standards. These requirements drove the design of a new CIM system which was developed for the Microelectronics Manufacturing Science and Technology (MMST) program. This paper provides an overview of the MMST CIM system framework which is based on open distributed system and object technologies. The CIM system was demonstrated in a 1000 wafer pilot production run in 1993 which achieved world record cycle time, and is now being commercialized as part of the WORKS product family from Texas Instruments 相似文献

随着社会的发展,ERP系统已经广泛应用于离散制造业,但是ERP系统本身基于无限产能、无资源约束的生产计划越来越无法满足需要。高级计划排程(APS)系统能够进行有限产能排程,但APS系统需要ERP的数据。本文从ERP与APS基本概念与理论出发,描述并分析了生产排程问题,设计了一种基于ERP系统的APS应用框架,描述并分析了其应用过程,从而为APS在离散制造生产排程中的应用提供了解决途径。 相似文献

Agent-based distributed manufacturing process planning and scheduling: a state-of-the-art survey 总被引:2,自引:0,他引:2

Manufacturing process planning is the process of selecting and sequencing manufacturing processes such that they achieve one or more goals and satisfy a set of domain constraints. Manufacturing scheduling is the process of selecting a process plan and assigning manufacturing resources for specific time periods to the set of manufacturing processes in the plan. It is, in fact, an optimization process by which limited manufacturing resources are allocated over time among parallel and sequential activities. Manufacturing process planning and scheduling are usually considered to be two separate and distinct phases. Traditional optimization approaches to these problems do not consider the constraints of both domains simultaneously and result in suboptimal solutions. Without considering real-time machine workloads and shop floor dynamics, process plans may become suboptimal or even invalid at the time of execution. Therefore, there is a need for the integration of manufacturing process-planning and scheduling systems for generating more realistic and effective plans. After describing the complexity of the manufacturing process-planning and scheduling problems, this paper reviews the research literature on manufacturing process planning, scheduling as well as their integration, particularly on agent-based approaches to these difficult problems. Major issues in these research areas are discussed, and research opportunities and challenges are identified. 相似文献

半导体制造系统的回流、资源高度共享等特征使得仅采用ERP系统已无法满足对生产规划与排程的种种需求.高级规划与排程(APS)系统的出现是为了强化ERP中以传统MRP规划逻辑为主的生产规划与排程功能,以协助规划人员对物料与产能做同步且最有效益的生产规划.APS系统利用先进的信息科技及规划技术,再考虑企业资源限制条件与生产现场的控制与派工法则,规划可行的物料需求计划与生产排程计划,具有同步规划、即时规划、最优规划等特点.对APS功能特色、APS导入时与ERP的衔接问题以及导入后各部门的运作进行了介绍及分析. 相似文献

多功能一体化雷达任务调度算法研究 总被引:1,自引:0,他引:1
雷达、电子战、通信等多功能电子系统一体化是雷达的发展方向之一,资源管理与调度技术是一体化雷达的关键技术。针对基于孔径分割实现雷达、电子对抗、通信等多种功能的一体化系统的任务调度问题,对系统任务建模、调度算法设计、算法评价指标进行了探讨。在研究常规相控阵雷达调度策略的基础上,提出了采用多任务并行EDF(Earliest Deadline First)算法来实现系统的自适应调度。最后对比常规多功能雷达的自适应调度进行了仿真比较,且对仿真结果进行了定量分析,结果表明采用多任务并行EDF(MTPEDF)算法的基于孔径分割的一体化雷达系统具有一定的优越性。 相似文献
