introduction: a large number of software programs have been used in dentistry for diagnosis and treatment planning to date. however, due to promotion of programming languages and developments in dental sciences, it is necessary to develop and update these softwares. use of softwares for treatment planning for removable partial dentures has been popular for some time and always new softwares hav...

One of the current problems in enterprise management system is creation and replenishment stocks, organization continuous monitoring prompt supply raw materials. Using mathematical models, you can solve problem forming optimal production program enterprise, investing production, as well to carry out strategic planning development. In each case, it important build a model that describes under st...

The present article elaborates a multi-product economic inventory model in which multiple items are considered with demand, depends on time, abides power law, shortages, and complete backordering. rate of production is greater than the demand for each item. This type pattern accessible to various kinds practical problems modern era. In this paper, assumed be directly proportional demand. real s...

Abstract: Inventory control systems development is one of the most appealing issues of the supply chain management which have recently been studied by academicians and practitioners. In this paper, an inventory management framework and deterministic cost models within the context of this framework are structured for effective supply chain (SC) in an agile environment. To do so, we propose a thr...

In this paper, an inventory management framework and deterministic costs models within the context of this framework are structured for effective supply chain under deterministic and fuzzy environment. In this regard, we propose a bi-echelon multi-product supply chain in which a central manufacturing firm (lower echelon) with warehouse space limitation is fed through different suppliers (upper ...

This paper develops a model of an integrated vendor–buyer supply chain with imperfect production and shortages. We assume that market demand is sensitive to the buyer’s selling price and thus study combined operations and pricing decisions in the supply chain. We first derive the expected profit per unit of time using the well-known renewal-reward theorem, and then maximize profit for the cases...

This paper introduces an integrated lot sizing and scheduling problem inspired from a real-world application in off-the-road tire industry. considers the assignment of different items on parallel machines with complex eligibility constraints within finite planning horizon. It also large panel specific such as: backordering, limited number setups, upstream resources saturation customers prioriti...

Motivated by practices in modern supply chains, we consider capacity-inventory joint management for a make-to-stock manufacturing system operating under a base stock policy. The production facility is modeled as multiple servers operating in parallel. The number of servers corresponds to the capacity decision and the base stock level is the inventory decision. The main problem which we consider...
