We study a collaborative multicommodity flow game where individual players own capacity on the edges of the network and share this capacity to deliver commodities. We present membership mechanisms, by adopting a rationality based approach using notions from game theory and inverse optimization, to allocate benefits among the players in such a game.
A common problem faced by carriers in liner shipping is the design of their service network. Given a set of demand to be transported and a set of ports, a carrier wants to design service routes for his ships as efficiently as possible, using the underlying facilities. Furthermore, the profitability of the service routes designed depends on the paths chosen… (More)
Many real world systems operate in a decentralized manner, where individual operators interact with varying degree of cooperation and self motives. In this paper, we study transportation networks that operate as an alliance among different carriers. In particular, we study alliance formation among carriers in liner shipping. We address tactical problems… (More)
We present new local search heuristics for the problem of scheduling jobs on identical parallel machines with the goal of minimizing total weighted completion time. Our proposed algorithm is a local search method based on combining a variable number of insertion moves. We develop an efficient heuristic for finding a profitable sequence of insertion moves.… (More)
Wireless communications is, by any measure, the fastest growing segment of the communications industry. As such,it has captured the attention of the media and the imagination of the public. Cellular systems have experienced exponential growth over the last decade and there are currently around two billion users worldwide.In this paper we use the vertical… (More)
The fundamental objective in restoring a defect created after total laryngectomy with a custom made silicone prosthesis is to enable the patient to cope better with the difficult process of rehabilitation after a major surgery has been performed. A cosmetically acceptable prosthesis that reproduces the color and form and allows the patient to return to… (More)
