Fuzzy Inventory Models of Perishable Multi-Items for

inventory model for deteriorating items with price-dependent demand and time-varying holding cost. Recently much work has been done regarding inventory models for deteriorating items. The life time of perishable items like perfumes, medicines, blood etc. are fixed and they cannot be used after the date of expiry. [6] have reviewed inventory

deterministic inventory model for price dependent demand with time varying holding cost and trade credit under deteriorating environment, supplier offers a credit limit to the customer during whom there is no interest charged, but upon the expiry of the prescribed time limit, the supplier will charge some interest.

Fixed Life Perishable Inventory Problem and Approximation

approximation model is less than 4%. 1 Introduction Controlling inventories of perishable items poses a significant challenge due to limited useful life of items. These items if not used before the expiry date would outdate and there would be an additional cost of outdating of perished items. To maximize total

holding cost as a function of time to manage the inventory of pharmaceutical items. A deteriorating inventory model considering price-de-pendent demand was given by Roy [9]. In this model, cost of holding of items was taken as dependent upon time. An order-level inventory model with time-quadratic demand

pro t. Chang [3] used preservation technology on non-instantaneous deteriorating items. Singh and Rathore [26] extended this model for shortages with the pro-posal of trade credit. Shah et al. [25] developed an integrated model by using preservation technology on time-varying deteriorating items when demand is time and price sensitive.

Inventory model with stock-level dependent demand rate and

inventory model with a stock-level dependent demand rate and a variable holding cost. In this model, the holding cost is an increasing step function of the time spent in storage. Two types of time-dependent holding cost increase functions are considered: Retroactive increase, and incremental increase. For each type, a simple algorithm that

Friedman (1978) presented a continuous time inventory model with time-varying demand. Silver (1979) developed an approx-imate solution approach to reduce the computational effort needed in the procedure proposed by Donaldson. Dave and Patel (1981) studied a inventory model for deteriorating items with time proportional demand.

Inventory Model for Deteriorating Items with Fixed Life under

inventory model with time-dependent quadratic demand and time-varying holding cost where units have expiry date. The model considered here allows shortages, and the demand is partially backlogged. The model is solved analytically by minimizing the total inventory cost. The results are illustrated with numerical example for the model.

In the past research many inventory model has been developed with and without deterioration. In the practical situation many products deteriorate time to time, which is manufactured like food items, chemicals, Pharmaceuticals, photography, papers etc. and many of products has expiry date. The demand rate may be

The problem consists of determining, in each period, the quantities of items to be purchased from the regular sup- plier and from the outsourced supplier such that all de- mand is satisfied and the total cost of purchasing, ship - ping and inventory holding is minimized.
