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...

In this paper, a production inventory model is considered for stochastic demand with the effect of inflation. Generally, every manufacturing system wants to produce perfect quality items. However, due to real-life problems (labor problems, machine breakdown, etc.), a certain percentage of products are of imperfect quality. The imperfect items are reworked at a cost. The lifetime of a defective ...

In the real world, vague phenomenon is quite common in the production/inventory models. In order to process the vagueness, a production/inventory model that can be more closely related to the real vagueness and can take account of the vague factors that contribute to production costs, is required. The model must be extended or altered to fit in with the fuzzy situation. Since items with imperfe...

Production lot-sizing has a special significance in supply chain taking into account the fact that majority of the lot-sizing problems are associated with NP-hard scheduling and sequencing problems. The complexity increases exponentially when multi-item capacitated dynamic lot-sizing is considered. The basic economic production quantity (EPQ) model minimizes the sum of setup and holding cost un...

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 ...

Variability of demand for goods, depending on their availability and cost is a frequently observed phenomenon in the sphere production consumption. This paper discusses possibility using ABC analysis inventory management system. type makes it possible to apply various methods increasing income reducing costs particular products manufacturers.
 As known, process approach emphasizes systemat...

In this paper, a bi-objective multi-product single-vendor single-buyer supply chain problem is studied under green vendor-managed inventory (VMI) policy based on the economic production quantity (EPQ) model. To bring the model closer to real-world supply chain, four constraints of model including backordering cost, number of orders, production budget and warehouse space are considered stochasti...

In this paper we consider a single machine system that produces items part of which are defective. The defective items produced in a time period, consisting of several equal cycles, are accumulated and are all reworked in the last cycle of this period called the rework cycle. At the end of the rework cycle the whole process will start all over again. The first significant objective of this stud...

Inventory management seeks to improve manufacturing by contracting inventory costs in a similar fashion raise efficiency and profit. One approach is develop models according actual production systems. Furthermore, governmental policies many countries impose regulations on firms fulfill the growing demand for reduction carbon emissions. Warm-up familiar concept industrial applications. It allows...
