In Pawlak's conflict system,the agent has only three opinions about issue,i.e.favorable,against and neutral.In this conflict system,conflicts are presented at the outermost level.It is difficult to know what are the conflict reason and how to find the scheme accepted by the most agents.In the real world,there are some conflict systems whose agents should have their own scheme.These conflict systems should have some scheme provided by the field expert.And there may be constrained relationship in different issues.According to these properties,we constructed a new conflict system based on Pawlak's conflict system.In the new conflict system,it is introduced the information system and the accepted scheme of each agent,the information system and the accepted scheme of the field expert,constrained conditions of different issues and accepted scheme of conflict system.At the same time,the algorithm for computing the accepted scheme of the conflict system is proposed.Finally,an example is used to illustrated the new conflict system model.And the example shows that the new model is eligible enough to depict some conflict systems in the real world.
