Many times it happens that units ordered are not of 100% good quality. A deterministic inventory model with imperfect quality is developed when the deterioration rate is Weibull distribution. Here it is assumed that holding cost is time dependent. The model has been framed to study the items whose deterioration rate increase with time under permissible delay in payments with imperfect quality. ...

This paper differentiates between an order (line) fill rate and a volume fill rate and specifies their performance for different inventory control systems. When the focus is on filling complete customer orders rather than total demanded quantity the order fill rate would be the preferred service level measure. The main result shows how the order and volume fill rates are related in magnitude. E...

In a perfectly transparent and competitive market, suppliers must provide pricing service for their customers. The aim of this study is to an insight into how preservation technology credit financing could be used both reduce the deterioration rate as well flexible retailers. methodology optimize cycle length, selling price, amount using inventory theory. result derived optimal total profit per...

Waste management and reworking are very crucial issues in the cleaner production system. The adaptation of preservation mechanism inventory control is also a key aspect from an economic environmental point view. In current study, model for system modelled considering all these practical inflation. Deterioration process takes place model, market demand viewed sales team efforts selling price dep...

In this paper, we conduct a simulation study to evaluate the impact of using imperfect advance demand information (ADI) in a single stage production/inventory system. We mean by ADI the fact that the production system receives customer orders in advance of their due-dates. We consider four types of ADI: 1) Perfect ADI, 2) ADI with imperfect due-dates, 3) ADI with imperfect demand quantities and...

We consider the problem of allocating demand arising from multiple products to multiple production facilities with finite capacity and load-dependent lead-times. Production facilities can choose to manufacture items either to-stock or to-order. Products vary in their demand rates, holding and backordering costs, and service level requirements. We develop models and solution procedures to determ...

This study deals with a two-level supply chain consisting of one manufacturer and one retailer. We consider an integrated production inventory system where the manufacturer processes raw materials in order to deliver finished product with imperfect quality to the retailer, where number of defective product has a uniform distribution. The retailer receives product and conducts a 100% inspection....

In manufacturing systems, defective items are produced for machine drift and error. Usually, an imperfect production rate is random, if the not reworked, these considered trash harm environment. The proposed model aims to reduce waste by reworking products maximizing profit. For profit maximization or overall cost minimization of system, setup has significant. A discrete investment each phase i...
