Abstract
Preventive maintenance is a means to ensure the component is kept in the desired state. Lack of preventive maintenance will cause unexpected consequences for the component, and too much preventive maintenance will result in unnecessary investment of resources. Based on the reliability data of the component, this paper establishes an analysis model to determine the optimal preventive maintenance interval of the component to make the cost of preventive and corrective maintenance lowest.
Highlights
The component may degrade or fail during the operation due to operating factors or its own material characteristics
Preventive maintenance is to reduce the probability of failure or functional degradation, carried out at predetermined intervals or according to prescribed criteria[1]
Constant interval preventive maintenance refers to do preventive maintenance of the component at a fixed time, and replacement will be carried out if the component fails during the working period
Summary
The component may degrade or fail during the operation due to operating factors or its own material characteristics. Preventive maintenance is to reduce the probability of failure or functional degradation, carried out at predetermined intervals or according to prescribed criteria[1]. The predetermined interval generally refers to the preventive maintenance of constant periods. The established criteria generally include status parameters and other types of preventive maintenance except for the constant interval. Constant interval preventive maintenance refers to do preventive maintenance of the component at a fixed time, and replacement will be carried out if the component fails during the working period. Include solution models targeting risk, cost, availability[2]. This paper is based on the cost model to study the method, which can be used to solve the preventive maintenance interval of the situation where the consequences of the failure will cause economic impact
