This study proposes a new multi-item inventory model with hybrid cost parameters under a fuzzy-stochastic constraint and permissible delay in payment. The price and marketing expenditure dependent stochastic demand and the demand dependent the unit production cost are considered. Shortages are allowed and partially backordered. The main objective of this paper is to determine selling price, mar...

this paper considers the fuzzy inventory model for deteriorating items for power demand under fully backlogged conditions. we define various factors which are affecting the inventory cost by using the shortage costs. an intention of this paper is to study the inventory modelling through fuzzy environment. inventory parameters, such as holding cost, shortage cost, purchasing cost and deteriorati...

In some real inventory systems, item sales can be adjusted to a stable demand rate along the cycle. For instance, home appliances, electrical products, lounge furniture, water supply, etc., are items with rate. this work, we analyze an system for of type, where is constant. Shortages allowed, and it assumed that fraction during stock-out period backlogged. It supposed shortage costs (backorder ...

Under stochastic demand and deterministic processing times, we discussed a single-part JIT production system with the production-ordering and supplier Kanbans and derived the stationary distributions of the backlogged demand. In this paper, we extend the system to a multi-part JIT production system, deterministic processing times and withdrawals with lead time. These conditions are more realist...

This paper considers a multistage serial inventory system with Markov-modulated demand. Random demand arises at Stage 1, Stage 1 orders from Stage 2, etc., and Stage N orders from an outside supplier with unlimited stock. The demand distribution in each period is determined by the current state of an exogenous Markov chain. Excess demand is backlogged. Linear holding costs are incurred at every...

<p style='text-indent:20px;'>This paper presents a mathematical framework to derive an inventory model for time, reliability, and advertisement dependent demand. This considers the demand rate is high initially, then reduces later stage, which reflects situation related cash in hand. The uncertain deterioration of product through Uniform, Triangular, Double Triangular probability distribu...

Purpose: The purpose of this paper to develop an inventory model for instantaneous deteriorating items with the consideration of the facts that the deterioration rate can be controlled by using the preservation technology (PT) and the holding cost & demand rate both are linear function of time which was treated as constant in most of the deteriorating inventory model. Design/methodology/approac...

In this paper, a multi-product economic production quantity problem with limited warehouse-space is considered in which the orders are delivered discretely in the form of multiple pallets and the shortages are completely backlogged. We show that the model of the problem is a constrained non-linear integer program and propose a genetic algorithm to solve it. Moreover, design of experiments is em...

<p style='text-indent:20px;'>The main purpose of this paper is to investigate the retailer's strategy in selecting order-up-to level, reorder point and preservation technology investment for deteriorating items, aiming maximize his total profit per unit time. We formulate problem into a mathematical model that takes account stock-dependent demand rate, holding cost. The terminal condition...

In this research work, a wholesaler-retailer-customer supply chain model for a deteriorating item is considered, where the retailer's warehouse in the market place has a limited capacity. The retailer can rent an additional warehouse (rented warehouse) if needed, with a higher rent compared to the existing warehouse (own warehouse). The customers' demand of the item is linearly influenced by th...
