We consider Nash–Cournot oligopolistic market equilibrium models with concave cost functions. Concavity implies, in general, that a local equilibrium point is not necessarily a global one. We give conditions for existence of global equilibrium points. We then propose an algorithm for finding a global equilibrium point or for detecting that the problem is(More)
Dependability is one of the critical system level issues in protocol design and it is not efficiently solved today. The main factor in this issue is the lack of design/modeling specifications with proper semantics. Most of the design specifications capture either hardware or software entities. In order to solve this problem we propose an architecture(More)
