<p style='text-indent:20px;'>In today's competitive markets, offering delay payments has become a commonly adopted method. In this paper, we examine an optimal dynamic decision-making problem for retailer selling single deteriorating product, the demand rate of which varies simultaneously with on-hand inventory level and length credit period that is offered to customers. addition, risk de...

Purpose: The purpose of this paper to develop an inventory model for instantaneous deteriorating items with the consideration of the facts that the deterioration rate can be controlled by using the preservation technology (PT) and the holding cost & demand rate both are linear function of time which was treated as constant in most of the deteriorating inventory model. Design/methodology/approac...

a r t i c l e i n f o The optimal replenishment policy for an economic production quantity (EPQ)-based inventory model with nonconforming items and breakdown is presented. A real-life production system inevitably generates nonconforming items and has equipment breakdowns owing to process deterioration or other uncontrollable factors. This study addressed these issues in an EPQ-based system to o...

This paper investigates a non-instantaneous deteriorating inventory model with an expiration date and hybrid payment scheme under price-sensitive demand, partial backlogged shortages. To facilitate post-Covid-19 recovery during the economic downturn, composed of multiple prepayments delay in is proposed. A time-dependent holding cost also introduced. Apart from this, shortages items are taken i...

This paper proposes another realistic application of the economic order quantity EOQ model. Researchers have studied EOQ models that assume the received lot contains items that are perfect and imperfect. All models in the literature assume that the received lot goes through a 100% inspection to separate acceptable items from the non-acceptable items. This paper argues that 100% inspection is no...

In this paper we have developed a continuous review inventory model for deteriorating items with time dependent demand rate. Deterioration rate is increasing with time. Each cycle has shortages, which have been partially backlogged. The backlogging rate is taken to be inversely proportional to the waiting time for the next replenishment. Fuzziness is introduced by considering demand rate and pa...

The Covid-19 epidemic has caused substantial obstacles to the supply network globally. Hence there is urgency and necessity build a model for cash flow in chain of demand system. This research suggests an inventory assist retailers determining optimal ordering quantity replenishment cycle reduce total cost different payment cases. current study looks toward partial advance delays system conside...

classical deterministic inventory models consider the demand rate to be either constant or time-dependent but independent from the stock status. however, for a certain type of inventory, the demand rate may be in-fluenced by the stock level. also in many real-life problems, some products such as fruits, vegetables, phar-maceuticals and volatile liquids continuously deteriorate to evaporation, o...
