Abstract: Contract net model and acquaintance model are two main models for softman cooperation.Based on the disadvantage of the two models，a new cooperation model which based on the acquaintance coalition and softman’s service centre is proposed，and the new model make it more efficiency in searching cooperator and more reliable in cooperation process.According to the acquaintance decision-making function and service center decision-making function，an effective collaboration softman can be quickly accessed.At the same time，using the two update strategies of acquaintance and service centre，the softman’s mind parameters can reflect changes in the environment.The results show that，the model based on the acquaintance coalition and softman’s service centre can significantly improve the cooperation efficiency.

Key words: softman, contract net protocol, acquaintance model, task cooperation

摘要： 软件人协作方法主要有合同网方法和熟人方法，针对这两种方法存在的问题，提出了基于熟人集和人才服务中心的软件人协作方法，解决了协作过程中寻找协作者的效率问题以及协作者的可靠性问题。根据熟人决策函数和服务中心决策函数，可以快速获取可以进行有效协作的软件人；同时利用软件人的熟人更新策略和服务中心更新策略，可以使软件人心智参数及时反映系统环境的变化。实验结果表明，基于熟人集和人才服务中心的软件人协作方法可以显著提高软件人协作的效率。
