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...

Water scarcity is an important obstacle to the development and expansion of urban landscape in the arid and semi-arid regions of the world. Nowadays organic and artificial materials can be used to reducing water consumption without reducing the quality and quantity of urban landscape. In order to study of the effect of some mulch type on the reduce of irrigation interval on a popular seasonal p...

This study revisits a fuzzy rough economic order quantity (EOQ) model for deteriorating items considering quantity discount and prepayment. Since the proposedmodel is amixed integer nonlinear programming type, it is solved using Meta heuristic algorithms. Based on three different case examples, we have shown that our results using the Bees Colony Optimization (BCO) algorithm performs better tha...

demand is assumed constant in the classical economic order quantity (eoq) model. however, in the real world, the demand is dependent on many factors such as the selling price, warranty of product and marketing effort. in addition pricing and ordering quantity decisions are interdependent for a seller when demand for the product is price sensitive in the inventory models. these types of models a...

Many operations are characterized by a trade-off between speed and quality. This calls for an exploration of effective strategies to balance the two metrics. study investigates separate joint effect quantity quality feedback on both performance metrics in order picking. We collected data from real-effort experiments with total 212 participants, who conducted picking task experimental warehouse....

A stable ventilation system is an essential guarantee for the efficient production and safety of underground workers. In order to solve big changes in air quantity, gas accumulation, other problems caused by mine main fans switchover. This paper proposes a non-stop switchover based on intelligent control establishes dynamic optimization model process fans. The equilibrium optimizer algorithm im...
