This paper focuses on sharing the costs and revenues of maintaining a public network communication structure.Revenues are assumed to be bilateral and communication links are publicly available but costly.It is assumed that agents are located at the vertices of an undirected graph in which the...

This paper deals with interactive multiple fund investment situations, in which investors can invest their capital in a number of funds.The investors, however, face some restrictions.In particular, the investment opportunities of an investor depend on the behaviour of the other...

This paper analyzes network problems with congestion effects from a cooperative game theoretic perspective.It is shown that for network problems with convex congestion costs, the corresponding games have a non-empty core.If congestion costs are concave, then the corresponding game has not...

The T -measure is introduces as a method to rank the nodes in a digraph competition.It coincides with the T -value of an associated transferable utility game, the so-called digraph game.The T -measure is characterized in two ways.One of them is based on a characterization of the T -value in...

This paper analyzes convex congestion network problems.It is shown that for network problems with convex congestion costs, an algorithm based on a shortest path algorithm, can be used to find an optimal network for any coalition. Furthermore an easy way of determining if a given network is...

A competition which is based on the results of (partial) pairwise comparisons can be modelled by means of a directed graph.Given initial weights on the nodes in such digraph competitions, we view the measurement of the importance (i.e., the cardinal ranking) of the nodes as an allocation problem...

A highway problem is determined by a connected graph which provides all potential entry and exit vertices and all possible edges that can be constructed between vertices, a cost function on the edges of the graph and a set of players, each in need of constructing a connection between a specific...

This paper considers a special class of sequencing situations with two parallel machines in which each agent has precisely two jobs to be processed, one on each machine.The costs of an agent depend linearly on the final completion time of his jobs.We describe a procedure that provides an optimal...
