Extensive research has been devoted to economic production quantity (EPQ) problem. However, little atten-tion has been paid to problems where depreciation cost and process quality cost must be considered, simulta-neously. In this paper, we consider the economic production quantity model of minimizing the annual total cost subject to depreciation cost and process quality cost, where depreciation...

Inventory situations, introduced in Meca et al. (2004), study how a collective of firms can minimize its joint inventory cost by means of cooperation. Depending on the information revealed by the individual firms, they analyze two related cooperative TU games: inventory cost games and holding cost games, and focus on proportional division mechanisms to share the joint cost. It turns out that ho...

This paper studies the parallel machine scheduling problem subject to machine and job deterioration in a batched delivery system. By the machine deterioration effect, we mean that each machine deteriorates over time, at a different rate. Moreover, job processing times are increasing functions of their starting times and follow a simple linear deterioration. The objective functions are minimizin...

The cooperation strategy followed by the buyer and vendor results is an overall effect on the saving percentage along with the impact of inventory costs such as holding cost, fixed and linear backorder cost. This paper deals with buyer vendor incentive inventory model with fixed lifetime product with fixed and linear back order cost. A distinguishing feature of this model is that both fixed and...

Probabilistic model; Inventory; Varying order cost; Holding cost; Lead-time demand; Uniform distribution; Safety stock Abstract This paper discusses the probabilistic backorders inventory system when the order cost unit is a function of the order quantity. Our objective is to minimize the expected annual total cost under a restriction on the expected annual holding cost when the lead time deman...

a new mathematical model for the optimal production isformulated for the inventory management system under time-varyingand stochastic inflation environment for deteriorating items. the timehorizon is finite and demand rate is dependent to the inflation. in thereal situation, some but not all customers will wait for backlogged itemsduring a shortage period, such as for fashionable commodities or...

This paper investigates a food supply chain model consisting of the supplier, producer and multi-retailer deteriorating item under fully delay-in-payment partial advance payment scheme. The deterioration rate raw material is dependent on temperature other environmental factors with respect to time. Here, prepares after collecting from supplier then storing it in cold storage. refrigeration cost...

In particular business transactions, the supplier usually provides an admissible delay in settlement to its vendor encourage further sales. Additionally, demand for commodity is inversely proportional function of sales price, which non-linear and, some situations, a holding cost rises over time. Moreover, many goods often deteriorate consistently and shall not be sold after their expiration dat...

Certain inventory items are living organisms, for example livestock, and are therefore capable of growing during the replenishment cycle. These items often serve as various saleable food items downstream in supply chains. The purpose of this paper is to develop a lot sizing model for growing items if the supplier of the items offers incremental quantity discounts. A mathematical model is derive...
