An inventory model with 3-variable Weibull distribution demand rate and constant deterioration is developed. The holding cost is constant. Shortages are not allowed. The salient feature of this inventory model is for non-perishable products or deteriorating items. A numerical example has been illustrated using MATLAB to describe the model and the sensitivity analysis of various parameters is ca...

The cooperative solution concept introduced here, the demand bargaining set, contains the core and is included in the Zhou bargaining set, eliminating the “dominated” coalition structures. The demand vectors belonging to the demand bargaining set are self-stable. In the class of constant-sum homogeneous weighted majority games the demand bargaining set is non-empty and predicts a unique demand ...

The cooperative solution concept introduced here, the Stable Demand Set, contains the Core and is included in the Zhou Bargaining Set, eliminating the “dominated” coalition structures. The demand vectors belonging to the Stable Demand Set are self-stable. In the class of constant-sum homogeneous weighted majority games the Stable Demand Set is non-empty and predicts a unique stable demand vecto...

In this paper, an economic order quantity (EOQ) inventory model for a deteriorating item is developed with the following characteristics: (i) The demand rate is deterministic and two-staged, i.e., it is constant in first part of the cycle and linear function of time in the second part. (ii) Deterioration rate is time-proportional. (iii) Shortages are not allowed to occur. The o...

In this paper, the cost function for a three-echelon inventory system with two warehouses is derived. Transportation times are constant and retailers face independent Poisson demand. Replenishments are one-for-one. The lead time of a retailer is determined not only by the constant transportation time but also by the random delay incurred due to the availability of stock at the warehouses. We co...

This paper shows that the CRRA specification of intertemporal preferences (implying a constant elasticity of intertemporal substitution, or EIS), imposes surprising limitations on within period budget allocations. Consequently, the constant EIS assumption can be tested with demand data. In fact, the parameter of the CRRA utility function is pinned down completely by the shape of Engel curves; i...

demand is assumed constant in the classical economic order quantity (eoq) model. however, in the real world, the demand is dependent on many factors such as the selling price, warranty of product and marketing effort. in addition pricing and ordering quantity decisions are interdependent for a seller when demand for the product is price sensitive in the inventory models. these types of models a...
