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 economic order quantity inventory model is analyzed, considering that the unit cumulative holding cost has two significant components: a fixed cost which represents the cost of accommodating the item in the warehouse and a variable cost given by a potential function of the length of time over which the item is held in stock. Shortages are allowed and, during the stockout perio...

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 ...

Abstract: This paper presents a new multiple objectives model for the optimal production for an inventory control system. The stocked items may be deteriorates and the systems costs will be change over the time. In the real situation, some but not all customers will wait for backlogged items during a shortage period and therefore, the model incorporates partial backlogging. The demand rate can ...

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...

Today, “Sustainable production” has attracted a great deal of interest by academic researchers and practitioners due to the raising environmental and social concerns. Sustainable EPQ model has been developed as a result of this interest and also necessity. This paper develops a novel sustainable EPQ (SEPQ) model under partial backordering consideration. The model converts all emission variation...
