    摘要: In an effort to achieve the lowest cost of goods (COG) possible, a key objective in batch manufacturing is to maximize equipment utilization so that the capacity and size of equipment per batch cycle is the smallest possible for a given batch production capacity. This optimization of equipment utilization minimizes equipment and direct utility costs per batch, as well as reduces the physical space and the associated utilities required to support manufacturing operations. The present invention provides a process of: (1) determining the optimal number of batch cycles per year for a required annual production capacity; and (2) determining the optimal number of equipment cycle iterations per batch cycle in a manner that: (a) creates the smallest batch sizes possible; and (b) achieves higher equipment utilization per batch cycle, thereby reducing the capacity and size of equipment required to produce a given batch quantity of product.

    摘要: By defining a section-related WIP limit or a throughput-related WIP limit, an efficient “look ahead” characteristic may be established to efficiently control the WIP in a complex manufacturing environment, such as a semiconductor facility. The respective critical WIP values may enable efficient reduction of priority of products moving towards an increased WIP queue, thereby reducing or substantially avoiding the release of products that are expected to run into the WIP queue. In this way, the efficiency of shared tools may be increased, since process capacity no longer required for the processing products running into WIP queues may be allocated for other operations.

    摘要: 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.

    摘要: A new operation is added to an operation plan while reducing the change amount in switch costs before and after change. An operation-plan scheduling device according to one embodiment is provided with a reader to read an operation plan, switch-cost information, information of an additional operation; a graph-network creator to create a graph network by setting intervals between operations allocated to the operation executors as an interval vertices, connecting edges among an entry vertex, an interval vertex, and an exit vertex, and setting weight variables on the edges; a path selector to select a path based on edge weight sums of the paths from the entry vertex to the exit vertex of the graph network; and an operation-plan creator to exchange operations between the operation executors in accordance with the selected path and allocate the additional operation to the interval created by the exchange.

    摘要: A method identifies a real time downstream to processing capability within a production environment using a computerized device. The processing sequences perform operations utilizing one or more tools. The method also determines if an upstream tool capacity is greater than a downstream tool capacity. When the upstream tool capacity is greater than the downstream tool capacity the method calculates an overlap value. The method then adjusts the run rate for the upstream tool to by dividing the run rate of the upstream tool by the overlap value. The method is a centralized system that references tool processing parameters to determine processing capability. In the cases where the upstream tool has a significantly shorter processing time than the downstream tool, the system is used to determine if value should be added at the upstream tool to avoid WIP build up at the downstream tool.

    摘要: A system and a method for managing a work-in-process (WIP) workload within a fabrication facility employ sequential processing of the work-in-process (WIP) workload within one each of a minimum of one pre-process tool, a minimum of one buffer tool and a minimum of one post-process tool. A buffer tool tolerance time is calculated predicated upon an available work-in-process (WIP) pre-process rate, an available work-in-process (WIP) buffer capacity and an available work-in-process (WIP) post process rate. The work-in-process (WIP) workload may thus be optimally processed in accord with the buffer tool tolerance time.

    摘要: A process is scheduled based on one or more tasks identified as control tasks from a set of tasks comprising part of a job. A desired work-in-progress load time level is set for each of the identified control tasks, and a time load on each of the identified control tasks is determined for each new job, each new job comprising one or more tasks. New jobs are released based on the desired work-in-progress load time level for one or more control tasks to approximately maintain the set desired work-in-progress load time level.
