The sustainable EPQ models that have been proposed in the inventory literature are insufficient to address practical scenario of defects manufacturing and subsequent rework for remedial actions. In this article, model with faulty products has studied. Promotional activities key factors significantly affect market demand an item. impacts random combining economic environmental elements on order ...

In this paper, we present a Markovian modeling framework that can describe any serial production system with rework. Under this framework, each production stage is represented by a state in the Markov chain. Absorbing states indicate the events of scrapping a product at a production stage or the completion of the finished product. Generalizable formulae for the final absorption probabilities ar...

The classical economic production quantity (EPQ) model is a well-known and commonly used inventory control technique. Common assumptions in this model are that all units produced are of perfect quality and shortage is not allowed, since in practice shortage, non-conforming product or scrap items are possible, these assumptions will underestimate the actual required quantity. The objective of th...

In this paper, a system-theoretic method, referred to as overlapping decomposition, is presented to estimate the production rate of a complex production system with assembly, parallel, rework, feed-forward and scrap operations. The idea of the method is to decompose the system into overlapped serial lines, and to modify the parameters of overlapping machines to accommodate the effects of other ...

Assisting designers in writing high-quality specifications is an important step towards minimizing product defects and rework efforts. Drawing on the attractive performance of satisfiability solvers, in this paper, we present a SAT encoding that enables an efficient model-based diagnosis of LTL specifications in the context of behavioral samples (traces). The resulting diagnoses at operator lev...
