【摘要】：復雜生產(chǎn)過程中受不確定性擾動因素的作用不可避免的會導致作業(yè)車間資源的退化、故障以及失效,針對故障資源修復順序?qū)Χ噘Y源耦合的復雜生產(chǎn)系統(tǒng)性能(如交貨期、生產(chǎn)成本等)的影響,引入復雜網(wǎng)絡(luò)理論構(gòu)建復雜生產(chǎn)作業(yè)車間網(wǎng)絡(luò)模型,對生產(chǎn)特性和網(wǎng)絡(luò)拓撲特性進行深入研究,對資源的故障修復進行緊迫性分級。綜合考慮影響故障修復緊迫性的三個因素:是否發(fā)生在關(guān)鍵路徑上、不可替代程度、故障節(jié)點的網(wǎng)絡(luò)重要度,采用模糊綜合評判的方法,將故障節(jié)點分為緊急、嚴重和一般三個層次,并計算出具體的緊迫度值。該模型為故障修復策略提供新的視角,為科學決策修復順序提供理論依據(jù)。最后通過仿真實例驗證了該方法的可行性。
[Abstract]:The effect of uncertain disturbance factors in complex production process will inevitably lead to the degradation, failure and failure of job shop resources. The performance of complex production systems coupled with multiple resources (such as delivery time) is due to the repair sequence of fault resources. Based on the influence of production cost, the complex network theory is introduced to construct the network model of complex production shop, and the characteristics of production and network topology are studied deeply. Three factors affecting the urgency of fault repair are considered comprehensively: whether it occurs on the critical path, the irreplaceable degree, the network importance of the fault node, and the method of fuzzy comprehensive evaluation. The fault nodes are divided into emergency, serious and general levels, and the specific urgency is calculated. The model provides a new perspective for fault repair strategy. It provides a theoretical basis for scientific decision repair sequence. Finally, the feasibility of the method is verified by a simulation example.
