A study of three classes of sequencing rules in a simulated job shop
… of jobs late, mean lateness and in-process inventory level were the measures of performance used. The results indicated that at low traffic density there was no appreciable difference among the measures of performance for the three sequencing rules. At high traffic density SPT had the lowest …

Review and improvement of reverse logistics in an electronics company
… reasons are its high operating cost and high inventory level. After reviewing its reverse logistics system, we found that current policy to process the returned product does not reap the maximum amount of profit from returns. We proposed to add a new channel to process the product returns. An …

Analyzing the make-to-stock queue in the supply chain and eBusiness settings
… the retailer control production and finish goods inventory level independently. The retailer carries finished goods inventory to service an exogenous demand and specifies a policy for replenishing his/her inventory from the upstream supplier. The supplier, on the other hand, chooses the capacity …

Determining Optimal Supply Level for Intermittent and Low Demand Parts
… aftermarket business is determining what optimal level of supply looks like for intermittent and low demand parts. For these parts, it is difficult to forecast the needed demand and set the right amount of inventory level. A number of these parts are Made-as-Order (MAO) with long lead times, …

Identifying inventory excess and service risk in medical devices : a simulation approach
… devices companies struggle to balance between inventory and service performance, as the products are non-interchangeable and inventory investment is expensive. To find the right level of inventory, we first used unsupervised clustering method to find demand pattern uncertainty for each product. …

Capacity control policies in a material requirements planning production environment
… structures are investigated, as well as several levels of the control parameters of each control policy. The results indicate that each control policy gives rise to a unique population of weekly labor, work in process, and inventory level. Product structure is also identified as a major variable …
