An inventory model for deteriorating items with fuzzy random planning horizon
نویسندگان
چکیده
An inventory model for deteriorating items over a fuzzy random planning horizon incorporating inflation and time value of money is studied. It is assumed that planning horizon follows exponential distribution with imprecise parameter. The model is formulated using cost minimization principle. As the fuzzy cost cannot be minimized directly, the possibilistic mean value of the fuzzy cost is found and then optimized. The model is illustrated with a numerical example.

This paper presents a production-inventory model for deteriorating items with stock-dependent demand under inflation in a random planning horizon. The supplier offers the retailer fully permissible delay in payment. It is assumed that the time horizon of the business period is random in nature and follows exponential distribution with a known mean. Here learning effect is also introduced for th...

In the present study, the Economic Order Quantity (EOQ) model of two-warehouse deals with non-instantaneous deteriorating items, the demand rate considered as stock dependent and model affected by inflation under the pattern of time value of money over a finite planning horizon. Shortages are allowed and partially backordered depending on the waiting time for the next replenishment. The main ob...
متن کاملA Production-Inventory Model for a Deteriorating Item Incorporating Learning Effect Using Genetic Algorithm
Demand for a seasonal product persists for a fixed period of time. Normally the “finite time horizon inventory control problems” are formulated for this type of demands. In reality, it is difficult to predict the end of a season precisely. It is thus represented as an uncertain variable and known as random planning horizon. In this paper, we present a production-inventory model for deterioratin...

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...
