This paper presents the idea of creating cells while reducing part-level sequence-dependent setup time in general cellular manufacturing systems (CMS). Setup time reduction in CMS has gained modest attention in the literature. This could be attributed to the fact that the fundamental problem in cell formation in CMS has been mainly related to material handling and machine utilization while setu...

This paper develops an economic lot-sizing production model for deteriorating items with time dependent quadratic demand and delay in payments under two levels of trade credit policy. The trade credit policy adopted here is a two-level trade credit policy in which the supplier offers the retailer a permissible delay period M, and the retailer in turn provides customers a permissible delay perio...

Abstract: In this article a single machine time-dependent scheduling problem with total completion time criterion is considered. There are n given jobs, j1, . . . , jn, and the processing time pi of the i-th job is given by pi = 1 + bisi, where si is the starting time of the i-th job, i = 1, . . . n. If all jobs have different and non-zero deterioration rates and bi > bj ⇒ bi ≥ bmin+1 bmin bj+ ...

In this study, an EOQ (Economic Order Quantity) inventory mathematical model is constructed for a deteriorating item having time dependent demand when delay in payment is permissible. The deterioration rate is assumed to be a constant and the time varying demand rate is taken to be an exponential declining function of time. Mathematical models are also derived under two different circumstances,...

Reduced Differental Transform Method (RDTM), which is one of the useful and effective numerical method, is applied to solve nonlinear time-dependent Foam Drainage Equation (FDE) with different initial conditions. We compare our method with the famous Adomian Decomposition and Laplace Decomposition Methods. The obtained results demonstrated that RDTM is a powerful tool for solving nonlinear part...
