Since Taiwan power company was established in May 1946, the company has long been a strong support to the development of the society and economy of Taiwan for half a century. However, the government started to implement the liberalization of electricity market and privatization of the company in 1995. As of the end of 2002, the government has approved 15 independent private producers to prepare to build the power stations. At present, the installed capacity of existing private power plants at that time reaches 15% of total electricity system in Taiwan and their power production reaches 13% of the total power production in Taiwan. The trend of competition arises at the electric market. From the productivity aspect, the overhaul period of nuclear power units in U.S was reduced from 105 days in 1990 to 37 days in 2001 during the 12 years. However, the overhaul period of nuclear power units of Taiwan Power Company was reduced from 77 days to 53 days at the same period of time. In one way, it shows there is an obvious space for Taipower to improve its productivity. Taiwan Power Company is a service company with lots of capital-intensive facilities for production of electricity. It is facing the internal challenges including equipment reliability, working safety, operational performance, corporate net income, shareholders’ and employees’ interests, social responsibility on the one hand; as well as the external challenges such as the increasingly brisk competition at the local liberalized market and the duties for improving the national core competency on the other hand. Therefore, it needs an immediate attention to improve the way of its operation. In this research, I am going to probe the most efficient operation strategy on the reliability and performance of the Taiwan Power Company. At the beginning of this research, I will use Weibull、Bayesian and Probabilistic Risk Assessment(PRA)proven models to integrate the information and therefore form a new model based on reliability theory. After that, the examples of four equipments of a nuclear station will be applied to this new model and prove this model is feasible. By this new proven new model, there is a new operation strategy with four constructs to be illustrated. The four constructs include changing the concept of operation; improving the knowledge of various hierarchical levels; enriching the contents of company system; and improving the flexibility of the organization. In conclusion, I would like to propose the following suggestions: In thinking, the Taiwan Power Company should adopt the maintenance model based on reliability theory model instead of time-based model. In planning, the company should consider the afore-mentioned constructs from the viewpoint of management. In implementation, the company should gradually proceed with measures step by step, from defrosting, transforming to refreezing, along with Chinese-style management. These measures will get the lean improvement strategy in shape, which, if actually fulfilled, will completely change the corporate constitution so as to improve the operation reliability and performance of the company.
