In the literature of inventory after the development of classical economic order quantity (EOQ) model researchers extensively studied several aspects of inventory modeling by assuming constant demand rate. But in a real market demand of a product is always dynamic state due to the variability of time, price or even of the instantaneous level of inventory displayed in retail shop. This impressed...

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...

In this paper, economic production quantity(EPQ)models for breakable or deteriorating items are developed with time dependent linear variable demands. Here rate of production and holding cost are time dependent and unit production cost is a function of both production reliability indicator and production rate. Set-up cost is also partially production rate dependent.The production process produc...

A fuzzy NLP EOQ model is developed with demand dependent unit cost of production and dynamic setup cost under limited capital investment and limited storage capacity. Here fuzziness is introduced in objective function, capital system and storage area. It is solved by fuzzy non-linear technique for linear membership functions. This paper allows the modification of the Single item EOQ model in pr...

the objective of this research is to tackle the emerging problem of jointly determining theoptimal retail price, the replenishment cycle, and the cost of preservation technology investment from an integrated perspective among the supplier and the manufacturer. this paper deals an integrated single-manufacturer single-retailer supply chain model for deteriorating items under revenue sharing on p...

This article deals with an economic order quantity (EOQ) inventory model for items with imperfect quality in fuzzy stochastic environment, wherein shortages are allowed and completely backlogged. Fuzzy stochastic environment means linguistic ‘impreciseness’ and statistical ‘uncertainty’ both appear simultaneously. Due to uncertain demand trend, imperfect production process, natural disaster etc...

In this paper we develop and analyse an inventory model for deteriorating items with mixture of Weibull rate of decay and demand as function of both selling price and time without shortages. Using the differential equations, the instantaneous state of inventory at time„t‟, the amount of deterioration etc. are derived. With suitable cost considerations the total cost function and profit rate fun...

this paper investigates an epq model with the increasing demand and demand dependent production rate involving the trade credit financing policy, which is seldom reported in the literatures. the model considers the manufacturer was offered by the supplier a delayed payment time. it is assumed that the demand is a linear increasing function of the time and the production rate is proportional to ...

In this paper a deterministic inventory model with imperfect quality have been developed for deteriorating items with two parameters Weibull distribution deterioration and time dependent holding cost. Shortages are allowed and are completely backlogged. The model has been framed to study the items whose deterioration rate increase with time under permissible delay in payments with imperfect qua...
