Model Of Maintenance Excellence

1 Introduction - Models of maintenance excellence

Business excellence is synonymous with business success that includes all elements of the excellence of a company: production excellence, maintenance excellence, excellence in logistics and other elements.

Maintenance excellence is a framework for a challenging critical review of the integrity and productivity of any business process or project.

Through maintenance excellence companies seek to provide a high quality process that supports continuous improvement and focuses on various areas such as strategy, employees, information, work, and other business aspects of maintenance [1, 2].

Criteria of maintenance excellence [1] are the guidelines for world maintenance practices. Using these criteria,

The definition of maintenance objectives can be viewed as a max / min principle - maximizing the output of maintenance that meets the technical accuracy of the equipment, minimizing inputs for maintenance in terms of the number of employees, financial resources and costs in general.

The most important thing is that all input factors interact with each other, considering that relatively small changes in any of the input factors can significantly affect the output or the working ability of the equipment.

There are many concepts of maintenance and improvement strategies such as: TPM - total productive maintenance, RCM - reliability centred maintenance, RBI - risk based inspection, LCC – life cycle costing, CMMS - computerized maintenance management software, maintenance management, spare parts management etc.

Problems arise when organizations use more than one concept simultaneously and start a new project in the middle of unfinished work, leading to the dissatisfaction of all participants in the project. The situation becomes even more complicated if the organization changed targets to improve maintenance from using increasing equipment effectiveness (reliability and availability) to reduce costs and vice

2 Preliminary research of maintenance excellence

The research of maintenance excellence was carried out in a real environment of a successful construction organization involved in civil engineering (construction of roads and road infrastructure). The organization owns modern machinery and transport equipment and employs around 200 workers of the needed professional profile. It is organized in a contemporary way, on the principles of an integrated management system and is certified according to the standards of ISO 9001, ISO 1400l and OHSAS.

The motives for a wider research of maintenance excellence were the results and the experience acquired with the self-assessment of the organization in the area of business excellence according to the EFQM model

2.1 Results of self-assessment based on EFQM model

Previous studies of business excellence based on the criteria of the EFQM model of evaluation were carried out in 2013. The preliminary results of the self-assessment are shown in Table 1
