“…[35]. Researchers have put forward many methods to express the effect of imperfect maintenance, and the typical treatment methods are the virtual age method, impact model method and so on [36]. Minor repair refers to equipment being restored to the state before the fault, after maintenance, without being changed [37].…”

Contemporary industrial equipment is increasingly developing towards complexity. In order to ensure the high reliability and sustainability of industrial equipment, more flexible maintenance strategies have attracted extensive attention. In view of this, this paper aims to summarize the current situation of existing maintenance strategies, so as to enable colleagues in the industry to choose or formulate more efficient maintenance strategies. Firstly, the characteristics, application potential and limitations of single component maintenance strategies, such as corrective maintenance, preventive maintenance and predictive maintenance, are described in detail from the perspective of maintenance time. On the basis of single component maintenance and the dependency between multiple components, the advantages and disadvantages of multicomponent maintenance strategies, such as batch maintenance, opportunity maintenance and group maintenance, are summarized, and suggestions for the future maintenance of industrial equipment are proposed. Based on this, industries can select the appropriate maintenance strategy according to their equipment characteristics, or improve their existing maintenance strategies based on actual needs.

“…Given this situation, it is essential for operators and engineers to continuously seek innovative strategies to improve maintenance schedules; since poorly maintained equipment and machines can generate random breakdowns, these mostly occur in many fields, such as production, industry, and manufacturing. Therefore, the implementation of a maintenance model is required to improve the availability of industrial machines and equipment that serve as pillars to maintain the competitiveness and profitability of the company belonging in all sectors of industry [10], [11]. Also, the maintenance model has to present the concept of system availability that minimizes the use of technology, maximizing its management to companies with lower turnover [12].…”

The operations in the cutting area are one of the most important activities in the metal-mechanic industry; therefore, the aim is to have the highest availability of the cutting machines. This shows how important this procedure is; in this sense, an improvement model is proposed through the application of lean manufacturing tools in a cutting machine, such as SMED, for the reduction of Set Up times; the application of the 5s methodology, to eliminate waste and increase productivity; TPM, to reduce the number of machine failures, together with a detailed maintenance plan. The model was tested by means of the arena software where the main objective was achieved, which was to increase the availability of the cutting machine by 6.45%, since it was possible to decrease the set up time from 15.71 minutes to 13.25 minutes, as well as to decrease the number of machine failures. This research allows SMEs in the metal-mechanic sector to increase their production and, therefore, generate a greater economic benefit.

“…Firstly, it enables planning in advance maintenance procedures connected with contact plates replacement, following which requires the provision of an adequate number of staff, service stands, tools and spare parts (new contact plates), cf. [14,16]. Maintenance works planning, in turn, provides a basis of estimating the operating costs [1].…”

The aim of the work was to develop a method of verification of the preventive renewal strategies, which enables a simulation evaluation of the effects of the application of a specific schedule of inspections of parts that are important in the operation of complex renewable technical objects. Using it requires having an already established schedule of inspections, and the result of applying the method is determined by indicators that assess the usefulness of the strategy, even before implementation. The developed computational tool was used to evaluate the renewal strategy of the current collector contact plates. Based on the real operational data, several renewal intervals were considered, determining the frequency of events involving the plate covering a specific mileage, from exceeding the wear control limit value to the next inspection (replacement). The proposed verification method is an important tool for testing and planning technical inspections for systems and elements with planned wear, and parts are periodically replaced.
