The goal of supply chain management is to provide products with best quality, low costs and shortest delay of delivery corresponding to customers’ expectations. To ensure that, companies must be in continuous research for management methodologies which allows them the possibility to improve their financial results by decreasing costs and improving their process and thus customers satisfaction. ...

Order processing and inventory management are critical to costs. Therefore, this research aims reduce cost lead time for case study construction material retailer. The objectives 1) the order of retailer; 2) analysis techniques in decision making determine appropriate quantity. 30 employees interviewed collecting data a company raw from January – December, 2021 is used as data. ABC EOQ calculat...

A purchasing inventory model with shortages where carrying cost, shortage cost, setup cost and demand quantity are considered as fuzzy numbers. The fuzzy parameters are transformed into corresponding interval numbers and then the interval objective function has been transformed into a classical multi-objective economic ordering quantity (EOQ) problem. To minimize the interval objective function...

In the newsvendor game, the expected-profit-maximizing order quantity is higher in the demand interval when the per-unit profit margin is high, and lower in the demand interval when the per-unit profit margin is low. However, laboratory experiments show a “pull-tocenter” effect: average order quantities are too low when they should be high and vice versa (Schweitzer and Cachon, 2000). We replic...

This paper develops an economic order quantity (EOQ) model with uncertain data. For modelling the uncertainty in real-world data, the exponents and coefficients in demand and cost functions are considered as interval data and then, the related model is designed. The proposed model maximises the profit and determines the price, marketing cost and lot sizing with the interval data. Since the mode...
