We have explained the planning method of maintenance schedule to ensure the high reliability at minimum cost. At the present, maintenance costs higher than re quired. This comes from mismatch between judgment of importance to be repaired and properties of equipment posses. Property means specification, potential loss or urgency that equipment possesses. To solve this subject, properties of equipment have to be evaluated suitably, and then maintenance management density as w ell. The important matter is est...

How to establish maximized optimized Plant Maintenance at low cost

This study proposes an innovative system based on risk evaluation and management for plant engineering and maintenance. This system was carried to completion by in troducing “Equipment Function“ to the conventional risk evaluation indexes comprised of “Process Property and “Equipment Property”. This new system is thought to b e very useful not only for plant operation to assure better performance and reliability together with realizing minimization of maintenance cost, but also to make g ood understanding ...

Plant Engineering and Maintenance based on Risk Evaluations Strategic Solution for Optimization Maintenance

Today, many troubles such as big accidents, human errors, active concealment, etc. are occurring frequently, and have had a bad influence on the reliability and security of a human life. As a cause of these problems, lack of information and knowledge, lack of tactics to safety ensuring, lack of the strategy to safety, etc. are pointed out. To solve these problems as mentioned, the technology concerning risk management immediatel y needs to be systematized. As such a technical system, we have proposed the c...

Plant Engineering and Maintenance based on Risk Evaluations (Part 2) Development of the Technology Knowledge Infrastructure

Management and maintenance tools are now greatly available for contributing reduction of maintenance cost and time. These tools surely give us much benefit, but are only for maintaining reliabilities of the equipment. Reliability of the plant dep ends on the design and actual operating conditions. Accordingly, the matter to do first is to consider facilities in the range of the plant life cycle. This brings the result that “process property” and “equipment property” are required besides “ equipment functio...

Application of Technology Knowledge Infrastructure to Plant Maintenance

１．リスクと保全学の関係 寿命が正確に予測でき、予測されたその寿命に至るまで設備は絶対に故障しないというのであれば、稼動中に設備が故障する懸念は全くないのだから、そこにリスクの概念を持ち込む余地はない。またリスクとはISO/IECガイド73でも述べるように、人が危険性を蒙る可能性とその危険性が与える危害の最大強度を組み合わせたものであるから、故障が発生しないのであれば被害が発生する懸念は一切ないからである。また保全の役割を単に設備の補修や整備、或いは故障させないための改良処方の開発に限る場合も保全はリスク......
