The study employed an innovative exercise-based instrument to identify individuals at risk for eating disorder (ED). The Exercise Orientation Questionnaire (EOQ), a reliable and valid instrument, was used to compare 80 ED patients, 74 obese patients, 99 elite runners, and 214 controls from a previous study. Runners resembled ED patients in scoring high on total EOQ and exercise intensity but di...

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 ...

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 ...

Inventory models with imperfect quality items are studied by researchers in past two decades. Till now none of them have considered the effect of substitutions to cope up with shortage and avoid lost sales. This paper presents an EOQ approach for inventory system with shortages and two types of products with imperfect quality by one way substitution. Our model provides significant advantage for...

In this paper, we use quasi-variational inequalities to provide a rigorous proof of the familiar square root formula for the optimal economic order quantity (EOQ) in the classical deterministic average cost inventory model.

An EOQ model of inventory for items with linear rate of deterioration is considered, taking the demand rate to be dependent on the stocjk level at any instant of time. The Payments are permitted to be delayed up to certain period of time. Shortages are not allowed. After the certain period, a special discount is permitted to reduce the stock in inventory because if the stock is holded, an inter...

In this paper, a discrete single-level multi-component inventory control model for assembly systems with random component procurement lead times is considered. The economic order quantity (EOQ) policy is used for a type of finished product. The requirements of the components are constant and cyclic (periodic), and their values per period are deduced from the EOQ for the finished product. The pa...
