PROBLEM TO BE SOLVED: To provide a production performance evaluation device of a machine system capable of performing a machine system design at high efficiency.SOLUTION: A production performance evaluation device includes: state transition definition means 11 for defining a state transition probability and an operation time between component states with respect to the component state defined by a position or an attitude which the component could take before and after the work process of a machine system; and route extraction means 12 for extracting a transition route from an initial state to a target state on the basis of the state transition probability and the operation time. The production performance evaluation device further includes: route cycle time calculation means 13 for calculating a route cycle time which is an expectation value of the time required for transiting between the component states for the route from the state transition probability and the operation time; and expectation tact time calculation means 14 for calculating an expectation tact time which is a time required for one component to become a target state by a machine system from the transition route extracted by the route extraction means 12.SELECTED DRAWING: Figure 3 【課題】高効率に機械システム設計をすることができる機械システムの生産性能評価装置を得ること。【解決手段】機械システムの作業工程の前後で部品が取りうる位置または姿勢によって定義される部品状態に対し、部品状態間の状態遷移確率と作業時間を定義する状態遷移定義手段１１と、状態遷移確率と作業時間に基づいて、初期状態から目標状態への遷移経路を抽出する経路抽出手段１２と、を備える。また、経路に対して、部品状態間を遷移するのにかかる時間の期待値である経路サイクルタイムを、状態遷移確率と作業時間とから演算する経路サイクルタイム演算手段１３と、経路サイクルタイムと、経路抽出手段１２で抽出された遷移経路から、機械システムで１つの部品が目標状態となるのにかかる時間である期待タクトタイムを演算する期待タクトタイム演算手段１４と、を備える。【選択図】図３
