    • A method and tool is provided to obtain an optimistic estimate or exact optimal value of an operational parameter for a realistic system model under investigation. The realistic system model includes components and paths arranged to process continuous or discrete commodities. The system could be a model of a manufacturing system with different machines (some of which may be identical) processing multiple job types, with different sequences of operations with different processing rates on the different machines at different stages. A network flow model of the realistic system model under investigation is generated. Constraints are applied to the abstracted network flow model, and a plurality of steady state network flows, which take into consideration the applied constraints, are performed. The network flows are combined or cascaded into an aggregate network flow, which captures a transformation of the commodities from a first state to a final output state. The network flow problem is solved using a general purpose or custom solver. The optimistic estimate or exact optimal value operational parameter estimate of the realistic system model under investigation is then returned. The method can be used to perform tradeoff studies between machine allocations, job mixes, operating costs, reliability and throughput, or to speed up scheduling and machine control.
    • 提供了一种方法和工具,以获得正在调查的现实系统模型的操作参数的乐观估计或精确最优值。 现实的系统模型包括用于处理连续或离散商品的组件和路径。 该系统可以是具有不同机器(其中一些可能相同)的处理多个作业类型的制造系统的模型,具有在不同阶段的不同机器上具有不同处理速率的不同操作序列。 产生了一个被调查的现实系统模型的网络流模型。 约束被应用于抽象网络流模型,并且执行考虑了所应用的约束的多个稳态网络流。 网络流被组合或级联成聚合网络流,其捕获商品从第一状态到最终输出状态的转换。 网络流程问题使用通用或定制解算器来解决。 然后返回对现实系统模型的乐观估计或精确最优值运算参数估计。 该方法可用于在机器分配,作业混合,运行成本,可靠性和吞吐量之间进行权衡研究,或加快调度和机器控制。
