A Fuzzy Inventory Model for Deteriorating Items with Price Dependent Demand
نویسنده
چکیده
A fuzzy inventory model with price dependent demand is considered. The shortages are allowed . The objective is to determine the optimal total cost and the optimal time length of the plan for the proposed model. The trapezoidal fuzzy numbers are introduced to achieve this objective. The signed distance method is used for defuzzification process. To illustrate the results of this model, sensitivity analysis is presented for both crisp and fuzzy model.

A New Inventory Model for Deteriorating Items with Price-dependent Demand, Time-value of money, and Shortages
This paper presents a discounted cash-flow approach to an inventory model for deteriorating items with the 
two-parameter Weibull distribution. According to our proposed model, two shortages are considered: back-orders and lost-sales, 
in which the back-order rate is a varying function of the time when the shortage happens. In general, the demand rate is a linear function of the selling p...

متن کاملA credit policy approach in a two-warehouse inventory model for deteriorating items with price- and stock-dependent demand under partial backlogging
Advertisement of the product is an important factor in inventory analysis. Also, price and stock have an important role to attract more customers in the competitive business situations. Trade credit policy is another important role in inventory analysis. We have combined these three factors together in a two-warehouse inventory model and represented it mathematically. In addition, we have added...
متن کاملA multi-objective inventory model for deteriorating items with backorder and stock dependent demand
Classical deterministic inventory models consider the demand rate to be either constant or time-dependent but independent from the stock status. However, for a certain type of inventory, the demand rate may be in-fluenced by the stock level. Also in many real-life problems, some products such as fruits, vegetables, phar-maceuticals and volatile liquids continuously deteriorate to evaporation, o...
متن کاملJoint pricing, inventory, and preservation decisions for deteriorating items with stochastic demand and promotional efforts
This study models a joint pricing, inventory, and preservation decision-making problem for deteriorating items subject to stochastic demand and promotional effort. The generalized price-dependent stochastic demand, time proportional deterioration, and partial backlogging rates are used to model the inventory system. The objective is to find the optimal pricing, replenishment, and preservation t...
