A New Mathematical Inventory Model with Stochastic and Fuzzy Deterioration Rate under Inflation

An Inventory Model with Fuzzy Deterioration and Fully Backlogged Shortage under Inflation

Looking through the inventory models with deteriorating items shows that the deterioration rate is considered constant in most of the previous researches. But,in the real world, deterioration rate is not actually constant and slightly disturbed from its original crisp value. In this paper a more realistic inventory model with fuzzy deterioration and fully backlogged shortage under inflation is ...

A Two Warehouse Inventory Model Under Inflation With Variable Deterioration And Partially Backordering

Developing a new stochastic competitive model regarding inventory and price

Within the competition in today’s business environment, the design of supply chains becomes more complex than before. This paper deals with the retailer’s location problem when customers choose their vendors, and inventory costs have been considered for retailers. In a competitive location problem, price and location of facilities affect demands of customers; consequently, simultaneous optimiza...

A Partial Backlogging Mathematical Model under Variable Inflation and Demand with Considering Deterioration Cost

The practical experiences reveal that the inflation is non-deterministic and variable. Therefore, a mathematical model for the optimal production for an inventory control system of deteriorating items is formulated under time-varying and stochastic inflation environment. The demand rate is a function of inflation and the time horizon is finite. In the real situation, some but not all customers ...

An Eoq Model with Ramp Type Demand Rate, Weibull Deterioration Rate and Partial Backlogging, under Inflation

In this paper, an inventory model with ramp type demand rate with inflation and time value of money is developed. The deterioration rate follows three-parameter Weibull distribution with the concept of life time of an item. Shortages are also allowed and unsatisfied demand is partially backlogged. The model is fairly general in practice, as the demand of some items such as fashionable items inc...
