    • Disclosed is a method of controlling a manufacturing system. The invention automatically monitors current levels of partially completed products waiting to be processed by a tool (or group of tools) and determines whether the current levels exceed a predetermined limit. If the current levels do exceed the predetermined limit, the invention performs an optimization process. However, if the current levels do not exceed the predetermined limit, the invention performs a dispatching process. In this dispatching process, the invention automatically projects future levels of partially completed products that will be supplied to the tool to identify a future work-in-process (WIP) bubble. The WIP bubble occurs when larger than normal amounts of partially completed products are supplied to the tool. The invention automatically adjusts the operating parameters of the tool based upon both the current levels and the future levels.
    • 公开了一种控制制造系统的方法。 本发明自动监视等待由工具(或一组工具)处理的部分完成的产品的当前水平,并确定当前水平是否超过预定极限。 如果当前水平超过预定极限,本发明进行优化处理。 然而,如果当前电平不超过预定限度,则本发明执行调度处理。 在这个调度过程中,本发明会自动将未来的部分完成产品的水平提供给工具,以识别未来的在制品(WIP)泡沫。 当大于正常量的部分完成的产品被提供给工具时,会出现WIP气泡。 本发明基于当前水平和未来水平自动调整工具的操作参数。

    • Allocating limited manufacturing resources to achieve a feasible production plan that is consistent with customer demand is a difficult and common problem faced in many manufacturing industries. For large-scale multi-stage manufacturing systems, existing methods are typically based either on allocating limited resources sequentially, according to a priority ranked list of production starts, or on linear programming based models. The output of such planning models is a production plan which specifies the quantity of each part to produce at each plant, using resources available to the enterprise. Typically there are lot-sizing rules defining the permissible production start quantities. The invention disclosed herein is a method for applying these rules to the lot-sizing of production starts within a linear program. It employs advanced heuristics that consider both established operational objectives (e.g. customer service, short lead times, low inventory, and prioritized allocation of supply and capacity) and lot-size rules to efficiently compute a feasible production plan for the division.
    • 分配有限的制造资源,实现符合客户需求的可行的生产计划是许多制造业面临的一个困难和常见的问题。 对于大型多级制造系统,现有方法通常基于依次分配有限资源,根据优先排序的生产启动列表,或基于线性规划的模型。 这种规划模型的产出是一个生产计划,其中规定了每个工厂生产的每个部件的数量,使用企业可用的资源。 通常,定义许可生产开始数量的批量规则。 本文公开的发明是一种将这些规则应用于在线性程序内的生产开始批量生产的方法。 它采用先进的启发式方法,考虑既定的经营目标(例如客户服务,交货时间短,库存量低,供应和容量优先分配)和批量规则,以有效地计算出该部门的可行生产计划。

    • A method and system for determining a plurality of coefficients of an objective function of a mathematical programming model. Attributes of the model are identified. A first set of coefficient values determining a first solution and initially representing the plurality of coefficients is determined by employing a specified ranking of the attributes. A prevailing solution is initialized to the first solution. Additional sets of coefficient values are generated, each set determining a corresponding additional solution of the model. The additional solutions are evaluated (e.g., by the Analytic Hierarchy Process) to provide a ranking of the solutions, where the ranking is dependent upon the attributes. The ranking of the additional solutions is used to select a second solution. The prevailing solution is set to the second solution if the second solution exceeds a sum of the prevailing solution and a specified tolerance.
    • 一种用于确定数学规划模型的目标函数的多个系数的方法和系统。 识别模型的属性。 通过采用指定的属性等级来确定确定第一解并且最初表示多个系数的第一组系数值。 一个普遍的解决方案被初始化为第一个解决方案。 生成额外的系数值集合,每组确定模型的相应附加解。 评估附加解决方案(例如,通过分析层级过程)以提供解决方案的排名,其中排名取决于属性。 附加解决方案的排名用于选择第二个解决方案。 如果第二个解决方案超过了主要解决方案和指定公差的总和,则将主要解决方案设置为第二个解决方案。
