    • A computer integrated manufacturing system executes a program process that performs a capacity planning method that allocates usage of a plurality of manufacturing elements of a manufacturing enterprise by major and minor apparatus, squeezing for overhead cost consideration, and site balance for maintain basic operation. The program process begins by receiving at least one fabrication forecast describing scheduling and types of product lots that are predicted to be fabricated within a first period of time by the manufacturing enterprise from at least one order management system of the manufacturing enterprise. Rolling statistics of products lots fabricated during a second period of time are retrieved from a data retention device of the computer integrated manufacturing system. Capacity planning for the allocation of the product lot predicted to be fabricated by the manufacturing elements is performed.

    • A method for monitoring the real-time production operation is disclosed. The used stage time, the used waiting time, and the theoretical remaining processing time is counted. The allowed stage time, the allowed waiting time, and the allowed slack time is also estimated. The critical stage ratio, the critical waiting ratio, and the critical slack ratio are then calculated by the following equations: critical stage ratio=allowed stage time/used stage time; critical slack ratio=allowed slack time/theoretical remaining processing time; critical waiting ratio=allowed waiting time/used waiting time. Thereafter, the status of the lot in a stage is graded according to its critical ratio of stage, slack, and waiting. Color codes are used to indicate the critical degrees. A stage critical degree report including the WIPs and the color codes is tabled to display all the statuses of the stage.
    • 公开了一种用于监视实时生产操作的方法。 计算使用阶段时间,使用的等待时间和理论剩余处理时间。 估计允许的舞台时间,允许的等待时间和允许的松弛时间。 关键阶段比例,临界等待比和临界松弛比率,然后通过以下等式计算:临界阶段比=允许阶段时间/使用阶段时间; 临界松弛比=允许松弛时间/理论剩余处理时间; 临时等待比=允许的等待时间/使用的等待时间。 此后,一个阶段的批次状况按照阶段,松弛和等待的临界比例进行分级。 颜色代码用于指示临界度。 提供包括WIP和颜色代码的阶段临界度报告,以显示舞台的所有状态。
