At the early 1980s, is an effective mathematic tool to deal with the uncertain or fuzzy knowledge. Rough rule theory has been widely used in information retrieval, digital library, software engineering and knowledge discovery. Its main idea includes acquisition of rough decision rules by reduction of data under the condition of keeping an invariability of classification capacity. And it basically represents a concept by a pair of approximation sets according to the partition on the given data based on the indiscernibility relation. Rough sets theory is well suited to deal with inconsistency of the rough approximations. So it is a new mathematical tool dealing with vagueness and uncertainty, and has found its applications in many areas such as AI, KDD, pattern recognition and classification and fault diagnosis.

This model decompounds the cooperative partners of virtual enterprises as the roles of the agile supply through analyzing the business process of the agile supply chain; an agent stands for one role of the agile supply chain. We give the architecture of agent negotiation and the reasoning process model based multi-agent negotiation with fuzzy logic control after analyzing the process of multi-agent negotiation. An evaluating principle of the cooperative partners is given for this reasoning process model firstly, then, we analyze the factor, which affect the agent evaluating the cooperative partners with the principle. An evaluation index system is designed for multi-agent and multi-issue and multi-level negotiation, then, we evaluate the proposal in the agent negotiation with the index system fuzzily and synthetically and the result range from 0 to 1. This evaluation method is generic, furthermore, for the adaptability of agent, partiality of agent can be defined manually or automatically, the user can adjust the partiality with changing the weight to optimize negotiation results.
