In addition, it improves the quality assurance of the safety and reliability of the maintenance work. Key merits of the system are:
1. Efficiently drawing up various documents for the maintenance work by using the stored data for the previous maintenance work and the pipe and instrument diagram (P and ID) data.
2. Supporting the management work for the contemplation of maintenance work safety by using the isolation information stored on the computer system.
3. Speed up the permission procedure by electronic mail and electronic permission.
4. Displaying additional information such as the specifications of equipment, maintenance result, and maintenance plan by linking up with the database of another system
5. Reducing the cost of hardware devices by using client/server network configurations of personal computers and a personal computer server. (author)
The Mitsubishi Electric Co., Ltd. has developed to introduce various computer systems for desk-top business assistance in a power plant such as system isolation assisting system, operation parameter management system, and so on aiming at business effectiveness for these ten and some years.
Recently, by further elapsed years of the plants when required for further cost reduction and together with the change of business environment represented by preparation of individual personal computer, further effectiveness, preparation of the business environment, and upgrading of maintenance in power plant business have been required.
Among such background, she has carried out various proposals and developments on the construction of a maintenance and management system integrated the business assistant know-hows and the plant know-hows both accumulated previously. They are composed of three main points on rationalization of business management and document management in the further effectiveness, preparation of the business environment, TBM maintenance, the introduction of CBM maintenance, and introduction of maintenance assistance in the upgrading of maintenance.
The present invention provides maintenance and management systems for providing aid so that these systems are combined effectively and operated rationally based on unified information management. That is, the system contains databases comprising information for the design of the equipment and pipelines of a plant, information for the exchange of equipment parts, information for the history of plant operation, information for the monitoring and inspection, and information for the management of repair operation,
In addition, it has an equipment part history management sub-system for managing equipment part exchange information, an operation history management subsystem for managing the operation state of the plant, an operation history management sub-system for managing equipment monitoring inspection data, and an operation management sub-system for managing periodical inspection/ repairing operation. These subsystems are collectively combined to manage the maintenance and management jobs of the plant unitarily. (I.S.)
For a variety of economic and technical reasons, there has been a growing concern with the aging of complex systems and components and the role that maintenance can play in reducing this degradation. A study for the Nuclear Regulatory Commission was recently undertaken to identify effective maintenance practices that could be adopted by the nuclear industry in the United States to assist in managing the aging degradation of plant systems and components. Four organizations were examined to assess the influence that their maintenance programs have on their ability to address the systems and component aging degradation issues.
