Abstract
A method of analyzing a manufacturing system. The manufacturing system includes a plurality of manufacturing resources. A set of orders is currently appointed for processing by the manufacturing system. Each order of the set of orders requires performance of at least one task. Each task is to be performed by at least a respective one of the manufacturing resources. The method includes determining stochastic parameters for each task of the plurality of tasks. The method also includes calculating a stochastic waiting time for at least one selected task of the plurality of tasks. The calculation is based at least in part on the stochastic parameters of the tasks.
