中文摘要：

组织能力是影响项目任务完成的决定性因素，而学习能力是组织能力形成的关键基础．基于元网络理论和动态仿真方法，将组织（人）、知识和任务视为多智能体复杂交互系统，提出知识扩散度和任务完成水平两项关键指标，研究项目组织学习能力对任务完成水平影响的内在机理．以通用品牌别克汽车4s店建设项目群管理为例，验证评价指标的合理性，并进一步通过仿真实验，识别项目组织的关键知识、关键组织以及关键学习阶段，进行组织学习能力提升和任务分配的优化，为项目组织设计、任务分配及组织学习的研究探索了一种有效的方法．

英文摘要：

Organiza~ion ability is the critical factor for project task completion, and learning ability is crucial basis for organizational ability formation. Based on recta-network theory and dynamic simulation method, this paper regards organization （people）, knowledge and task as complex interactive system of multi-agent and puts forward 2 measurement indexes （knowledge diffusion and task completion）, research- ing the internal mechm~ism of learning ability of project organization to influence task completion. Finally, taking General Motors （GM） Buick 4S Shop Construction Project Group Organization as a case, this pa- per further identifies the key knowledge, key agent and key learning phase of project organization through simulation after reasonable confirmation of measurement indexes and optimizes organization learning abil- ity and task assignment. Furthermore, this paper provides effective methodology for research of project organization design, optimization of task assignment and organization learning.
