Application of Uncertain Programming to an Inventory Model for Imperfect Quantity under Time Varying Demand

چکیده
In the present paper we investigate a EOQ model for imperfect items under time variable linear demand. The defective items is being screened out by a 100 % screening process and then sold in a single batch by the end of the 100% screening process with a salvage price. The unsold perfect item during the cycle is sold at a different salvage price at the end of cycle. Two different types for cost parameters are considered namely crisp constant and uncertain variable. For each case, optimal policy is obtained. We have considered expected value model and uncertain chance constraint programming for the Uncertain EOQ model. Numerical example and sensitivity analysis are provided to illustrate the effectiveness of the above models. keywords Inventory, Imperfect quality; Economic Order Quantity

An integrated production-marketing planning model With Cubic production cost function and imperfect production process
The basic assumption in the traditional inventory model is that all outputs are perfect items. However, this assumption is too simplistic in the most real-life situations due to a natural phenomenon in a production process. From this it is deduced that the system produces non-perfects items which can be classified into four groups of perfect, imperfect, reworkable defective and non-reworkable d...
متن کاملAn inventory model for deteriorating items with time-dependent demand and time-varying holding cost under partial backlogging
In this paper, we considered a deterministic inventory model with time-dependent demand and time-varying holding cost where deterioration is time proportional. The model considered here allows for shortages, and the demand is partially backlogged. The model is solved analytically by minimizing the total inventory cost. The result is illustrated with numerical example for the model. The model ca...

The purpose of this article is to model and solve an integrated location, routing and inventory problem (LRIP) in cash-in-transit (CIT) sector. In real operation of cash transportation, to decrease total cost and to reduce risk of robbery of such high-value commodity. There must be substantial variation, making problem difficult to formulate. In this paper, to better fit real life applications ...
متن کاملAn inventory model for non-instantaneous deteriorating items with imperfect quality, delay in payments and time value money
In this paper, Economic Order Quantity ( ) based model for non-instantaneous deteriorating items with imperfect quality, permissible delay in payments and inflation is proposed. We adopt a time-dependent demand function. Also, the effects of time value of money are studied using the Discounted Cash Flow approach. Moreover, we assume that orders may contain a random proportion of defective items...
متن کاملAn EMQ inventory model for defective products involving rework and sales team’s initiatives-dependent demand
This paper investigates the issue of an economic manufacturing quantity model for defective products involving imperfect production processes and rework. We consider that the demand is sensitive to promotional efforts/sales teams’ initiatives as well as the setup cost can be reduced through further investment. It also assumes that fixed quantity multiple installments of the finished batch are d...
