Most of the real-world optimization problems involve multiple objectives with constraint resources. Retailers oftentimes anticipate demand, they stock, and maintain warehouses different variety products at high cost to meet prospecting customers' demand. In this paper, a Non-preemptive Integer Nonlinear Goal Programming (NINGP) model was developed for obtaining Economic Order Quantities (EOQ) m...

This study aims to find out how control raw material inventory which is traditionally carried by the Tempeh Soybean Factory analyzing using Economic Order Quantity (EOQ) and Periodic (POQ) methods. In this study, we uses a descriptive-qualitative approach. The author observation, interviews, documentation in collecting data. resource persons consisted of factory owners, assistants, employees at...

SME Sido Luhur is a producer that processes raw coffee beans who have problems ordering every month which considered to result in higher inventory costs. The sample this study were owner determined based on judgment sampling. research was conducted at starting September 2022. This used primary data obtained through interviews and secondary from the cost quantity of materials 2018. Data for 2018...

Abstract—In this paper, Economic Order Quantity (EOQ) based model for non-instantaneous Weibull distribution deteriorating items with power demand pattern is presented. In this model, the holding cost per unit of the item per unit time is assumed to be an increasing linear function of time spent in storage. Here the retailer is allowed a trade-credit offer by the supplier to buy more items. Als...

In this paper, an EOQ inventory model is depleted not only by time varying demand but also by Weibull distribution deterioration, in which the inventory is permitted to start with shortages and end without shortages. A theory is developed to obtain the optimal solution of the problem; it is then illustrated with the aid of several numerical examples. Moreover, we also assume that the holding co...
