中文摘要：

在PAWLAK提出的冲突系统中，局中人对争端的态度只有3种：肯定、否定或中立。这样的冲突系统提供的信息过于抽象，很难从该模型中了解局中人产生冲突的原因，更无法找到大多数局中人一致同意的方案。经深入研究，认为现实生活中的某些冲突系统，其局中人应具有自己的方案，而整个冲突系统应有领域专家提供的方案。同时，各争端之间可能存在相互制约关系。根据这些特点，在PAWLAK冲突系统模型的基础上，引入每个局中人的信息系统和可行方案、领域专家为冲突系统提供的信息系统和可行方案，以及冲突系统中各争端的约束条件和冲突系统的可行方案，从而得到一个新的基于粗糙集的冲突模型。同时，给出了一个求冲突系统可行方案的算法，并以实例说明新模型能较好地刻画现实在生活的某些冲突系统。

英文摘要：

In Pawlak＇s conflict system,the agent has only three opinions about issue,i, e. favor-able ,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.
