This paper outlines efforts to model, simulate and ultimately optimize knowledge flows in Edge organizations. We begin by reviewing Phase I research which explored how knowledge inventory flows through organizations, analogously to perishable, physical goods inventory in a supply chain, and uncovered useful insights to clarify current understanding and permit initial quantification of knowledge...

in any supply chain, distribution planning of products is of great importance to managers. with effective and flexible distribution planning, mangers can increase the efficiency of time, place, and delivery utility of whole supply chain. in this paper, inventory routing problem (irp) is applied to distribution planning of perishable products in a supply chain. the studied supply chain is compos...

this paper aims to investigate the integrated production/distribution and inventory planning for perishable products with fixed life time in the constant condition of storage throughout a two-echelon supply chain by integrating producers and distributors. this problem arises from real environment in which multi-plant with multi-function lines produce multi-perishable products with fixed life ti...

We study a perishable inventory system that requires to maintain a fresh and large quantity of inventory at all times. For example, certain pharmaceuticals are kept for emergency preparedness and response operations. We aim to maximize the profit by optimizing the joint problem of the ordering and issuing policies while maintaining a minimum amount of perishable inventory. First, we consider a ...

The federal government maintains large quantities of medical supplies in stock as part of its Strategic National Stockpile (SNS) to protect the American public in case of a public health emergency. Managing these large perishable inventories effectively can help reduce the cost of the SNS and improves national security. In this paper, we propose a modified Economic Manufacturing Quantity (EMQ) ...

The costs of many economic activities such as production, purchasing, distribution, and inventory exhibit economies of scale under which the average unit cost decreases as the total volume of the activity increases. In this paper, we consider an economic lot-sizing problem with general economies of scale cost functions. Our model is applicable to both nonperishable and perishable products. For ...

this paper deals with an i * corresponding author email address:   nventory system with one central warehouse and a number of identical retailers. we consider perishable-on-the-shelf items; that is, all items have a fixed shelf life and start to age on their arrival at the retailers. each retailer faces poisson demand and employs (1, t) inventory policy. although demand n...

In this study, we develop a collaborative inventory system consisting of one supplier and one buyer. The objective is to maximize the total profit of the whole system when shortage caused by the imperfect quality can be completely backordered. To ensure mutual benefits to every player, a negotiation mechanism is incorporated to share the profit between both players according to their contributi...
