<p>PURPOSE:To improve the analytic efficiency by extracting an equivalent partial network in requested analytic accuracy, in the case of analyzing a part of a queue network. CONSTITUTION:An input part 7 inputs information 2 related to a queue network constituted by using a queue which has one piece or more of input arcs and one piece or more of output arcs, and also, whose output branch is probabilistic, as a node, and an analytic object partial network, and information 3 related to analytic accuracy and holds them in storage parts 4-6. A detecting part 8 detects the input arc to the analytic object partial network, based on the inputted information related to the analytic object partial network. A dependence calculating part 30 calculates a degree of dependence to other arc of each detected input arc thereof. An output part 14 extracts and outputs an equivalent partial network in requested analytic accuracy, from the information related to the inputted queue network, based on a result of calculation of the degree of dependence and the inputted information related to the analytic accuracy.</p> |
