General multi-state rework network and reliability algorithm

A rework network is a common manufacturing system, in which flows (products) are processed in a sequence of workstations (nodes), which often results in defective products. To improve the productivity and utility of the system, the rework network allows some of the defective products to go back to the "as normal" condition after the rework process. Since 2017 [1, 2], the traditional study proposed an algorithm to correct more than 21 archive publications regarding the rework network reliability problem, which is an important real-life problem. In addition to traditional research, we provide an accurate general model based on the novel state distribution with a smaller number of limitations. Furthermore, we propose an algorithm to calculate the reliability of the multi-state rework networks using the proposed novel state distributions.
