Productive operation of a large computer network serving multiple user facilities in conjunction with several host sites requires the use of network management. As treated here, network management includes an array of such methods as communication systems management, problem management, change management, and inventory management. In this paper the use of some of the management techniques is de...

an integrated model considers all parameters and elements of different deficiencies in one problem. this paper presents a new integrated model of a supply chain that simultaneously considers facility location, vehicle routing and inventory control problems as well as their interactions in one problem, called location-routing-inventory (lri) problem. this model also considers stochastic demands ...

background: according to the available evidence and experiments, problem-based learning is one of the most successful methods to achieve higher educational objectives. in this method, the discussion about the medical sybjects to be learned by the students is based on a real clinical case and participation of the students. various advantages and disadvantages of this method have been addressed i...

F many companies, inventory record inaccuracy is a major obstacle to achieving operational excellence. In this paper, we consider an inventory system in which inventory records are inaccurate. The manager makes inventory inspection and replenishment decisions at the beginning of each period. There is a cost associated with each inspection. If an inspection is performed, inventory records are al...

Title of Dissertation: ONLINE INVENTORY REPLENISHMENT AND FLEET ROUTING DECISIONS UNDER REAL-TIME INFORMATION Ricardo Giesen, Ph.D., 2007 Dissertation Directed By: Professor Hani S. Mahmassani, Civil and Environmental Engineering Department Logistics managers rely on increasingly sophisticated technologies to track demand and associated inventories, allowing rapid response to meet anticipated d...

We investigate the polyhedral structure of the lot-sizing problem with inventory bounds. We consider two models, one with linear cost on inventory, the other with linear and fixed costs on inventory. For both models, we identify facet-defining inequalities that make use of the inventory bounds explicitly and give exact separation algorithms. We also describe a linear programming formulation of ...

In this paper, the multicast protection problem on elastic optical networks (EONs) for the single link-failure case is studied. The segment-based protection is used as the multicast protection scheme and two algorithms are proposed to solve this problem, they are Low Spectrum First Segmented Protection Algorithm (LSF-SPA) and K-Tree Segmented Protection Algorithm (KT-SPA). The proposed algorith...
