Markup pricing contracts have been widely employed in many industries. Under such contracts, a retailer charges a retail margin over the wholesale price levied by the supplier to guarantee her financial prudence. In a setting where two competitive manufacturers sell substitutable products through a common dominant retailer, we investigate and compare performance of two different markup arrangem...

A fuzzy NLP EOQ model is developed with demand dependent unit cost of production and dynamic setup cost under limited capital investment and limited storage capacity. Here fuzziness is introduced in objective function, capital system and storage area. It is solved by fuzzy non-linear technique for linear membership functions. This paper allows the modification of the Single item EOQ model in pr...

This paper studied pricing, service level, and production quantity decision problems in a supply chain with one manufacturer and one retailer under demand and production cost disruptions. The joint impact of demand and production cost disruptions on optimal pricing, service level, and production decisions in centralized and decentralized supply chain was analyzed, respectively. By solving the o...

It is only an order quantity which is decided for a spot selling time in the classical newsboy problem. Both the purchase timing and the time-variant variance of the demand are neglected. When the vendor gives a price discount for early purchase, the buyer purchases the quantities of price discount at the cost of forecast bias. The buyer has to forecast the demand early before purchase ahead of...

This paper presents an inventory model for deteriorating items with stock-dependent selling rate under inflation and time value of money over a finite planning horizon. In the model, shortages are allowed and the unsatisfied demand is partially backlogged at the exponential rate with respect to the waiting time. We establish the theoretical results and provide an efficient solution procedure to...

The objective of this model is to discuss the inventory model for time varying demand and time dependent holding cost. Mathematical model has been developed for determining the optimal order quantity, the optimal cycle time and optimal total inventory cost in fuzzy environment. For defuzzification, graded unit preference integration method is used. Numerical examples are given to validate the p...

In this paper we discuss the possible affects of inflations by the supplier on a retailer’s replanishment policy for time-dependent deteriorating items with constant demand rate. This optimal order quantity is obtained for all four cases i.e. for case 1, 0<T<Td , case 2, Td ≤T<M, case 3, Td ≤M ≤T and case 4, M≤ Td <T. The optimal total relevent cost is obtain for all these four cases which is m...

The inventory models analyzed in this paper explore the problem in which the lead time and ordering cost reductions are inter-dependent in the continuous review inventory model with backorder price discount. The objective is to minimize total related cost by simultaneously optimizing the order quantity, reorder point, lead time and backorder price discount. Moreover, we assume that the mean and...

To analyze effects of supply chain coordination for deteriorating goods with stock-dependent demand rate, this paper presents decision models for order quantity and ordering cycle under two scenarios( decentralized supply chain, centralized supply chain). Numerical study is carried out to demonstrate the effectiveness of the proposed models, and to analyze the impact of supply chain coordinatio...
