The development of the inventory model started when Harris introduced classic model. It was firstly published by Wilson using optimization method. He derived a mathematical equation to obtain economic order quantities. Later, this is known as Economic Order Quantity (EOQ) or Model. EOQ has some limitations. assumed that items do not have physical changes during planning period. This assumption ...

The main purpose of this paper wants to investigate the optimal retailer’s lot-sizing policy with two warehouses under partially permissible delay in payments within the economic order quantity (EOQ) framework. In this paper, we want to extend that fully permissible delay in payments to the supplier would offer the retailer partially permissible delay in payments. That is, the retailer must mak...

This paper corrects an improper expression in the economic order quantity (EOQ) model with two-warehouses and imperfect quality developed by Chung et al. [2009. A twowarehouse inventory model with imperfect quality production processes. Computers & Industrial Engineering 56, 193-197]. The modiT ed model yields a simple and corrected expression for the optimal order quantity and expected proT t ...

Inventory management is the core of supply chain system, in which economic order quantity (EOQ) model a fundamental inventory model. This paper develops fuzzy EOQ presence inspection errors single sampling plans. The assumes probability mis-classifications. An system hypothesized where orders undergo acceptance sampling, back-orders are eliminated, and defectives set aside from inventory. Due t...

In 1985, Goyal considered the retailer’s inventory replenishment problem under trade credit independent of the order quantity and the retailer’s unit selling price and the purchasing price per unit were equal. In this paper, the restrictive assumptions of the trade credit independent of the order quantity and the retailer’s unit selling price equaled to the purchasing price per unit are relaxed...

The application of inventory management in the hotel's Food & Beverage (F&B) division is examined this article. F&B struggles greatly to maintain ideal stock levels while assuring effective operations and lowering costs. department uses a well-known model seeks balance price placing orders with cost maintaining inventory. main ideas Economic Order Quantity (EOQ) are covered article ...

The Lambert W function dates back to Euler’s time and despite offering solutions to many operations management problems it is still relatively unknown. This may be due to the fact that it is only incorporated into specialist mathematical software and is not generally available in common spreadsheet applications. This obscurity is rather unfortunate as it is relatively easy to use when the signi...
