Vulnerability Evaluation for a Smartphone Digital Twin Workshop under Temporal and Spatial Disruptions

نویسندگان

چکیده

Dynamic performance analysis is essential for production systems facing random disturbances. In this paper, a vulnerability evaluation approach proposed smartphone assembly with finite buffers under resilient system analytic frame. Firstly, four important indicators, namely Terminal Time Delay (TTD), Window (TTW), Bottleneck (BTD), and (BTW), are defined to expound temporal spatial attributes caused by disruptive events. Then, recursive derivation of the queuing network model presented obtain state-transition matrix, wherein machine reliability also considered in model. Afterward, exact solutions steady transient evaluated based on state probabilities inference. Finally, numerical studies carried out validate method translate it into practical tool. An application program disturbance control functions developed, embedded digital twin independently developed our team solve problems.

An integrated model for designing a distribution network of products under facility and transportation link disruptions

Due to occurrence of unexpected disruptions,a resilient supply chain design is important. In this paper, a bi-objective model is proposed for designing a resilient supply chain including suppliers, distribution centers (DCs), and retailers under disruption risks.The first objective function minimizes total costs. The second objective function maximizes satisfied demands. We use the augmented e-...
