我国实行社会主义市场经济后，兖矿通讯计算中心的环境、性质发生了急剧而深刻的变化，在计划经济条件下形成的管理体制、组织结构、经营体系和业务流程等已不适应环境变化，而市场经济的压力使得通讯计算中心迫切需要变革自身。在进行机制转型和网络改扩建的同时，拟通过业务流程再造，建立一种切合实际而又可行的面向顾客的业务流程和新的组织形式，以降低成本，激发职工的积极性和创造性，提升市场竞争力，促使通讯计算中心快速、健康的发展。 本文在研究了兖矿通讯计算中心进行业务流程再造的可行性后，建立了通讯计算中心的业务流程再造模型，通过利用流程图模型工具分析了通讯中心现有的流程结构和核心的业务流程，建立了顾客导向的新业务流程结构，并对核心业务流程进行设计。为了适应新流程的，进行了信息系统、组织结构等方面的辅助设计。最后，通过分析实施业务流程再造绩效提高的机理，建立了实施效果评价体系，运用多层模糊评价方法，实施流程再造的效果进行评价，得出了企业绩效显著提高的结论。 论文的研究成果已在通讯计算中心的实践中得到实施，取得了显著的成效，本文的一些观点和思路对进一步深化企业的内部改革具有一定的指导作用。

After the socialist market economy is put into practice in China, the environment and nature of Yankuang telephone computer center has changed rapidly and dramatically. The management system, organizational structure, marketing system and business process have become unfit for the new environment. Furthermore, the center of yangkaung need innovate urgently due to the pressure of market economy. Through business process reengineering, we hope that the center reduce products’ cost, stimulate the staffs working activity and creativeness, increase our products’ market share, competition that promotes our center development highly and healthy.. Basing on the feasibility the center of yankuang, we set up the business process reengineering model of the center of yankuang. Through analyzing the business process with process diagram, we design the business process structure and the core business processes based on customer. At last, this paper analyzes the mechanism of process reengineering affecting the performance. On the basis of this, it sets up an evaluating indexes system and evaluates the result of implementing business process reengineering by multi-fuzzy method. We draw a conclusion that the performance of the center has improved significantly.
