This method uses constraint net to express variable and constraint relationship of negotiation in negotiation model.

Analysis of market power behavior of electricity suppliers under network constraints;

Market power detection based on network constraints;

In a competitive electricity market, the oligopoly structure of the market and the network constraints may produce results far from the perfect competition.

Chaos optimization algorithm has been used to find a global optimal solution to realize conflict resolution in the mathematic method based on constraint networks in collaborative design,and the efficiency is simulated by usual optimizing function.

A specification reflecting the satisfactory degree of the constraint networks is constructed, and the bottleneck variables are found with a genetic algorithm.

The system which is based on consistent interval solving algorithm of constraint networks can detect conflicts in product design process effectively by computing feasible intervals of design parameters in constraint networks.
