This paper describes a comprehensive approach to ensuring equipment maintenance and repair organization (MRO) efficiency in solving tasks with supporting tools and a systematic approach. Types of support for MRO, classification of MRO methodologies, basic organization aspects of the program, information and methodical support for MRO, which makes maintenance and repair body of knowledge (M&R BOK) are presented. The problem of maintenance and repair organization, the MRO process formalization aspects is showed. The main essence of the MRO process was highlighted. The ways of improving MRO by using the system approach, correlated goals and key performance indicators, and also some methods of improving the MRO organization efficiency are proposed. The MRO process formalization with functional and business models and incorporating them into a common information MRO support model is proposed. The MRO KPI was described as a model. The principal algorithm of the continuous MRO improvement based on KPIs was proposed. The task of MRO knowledge accumulation and using was considered. Using the ontology for knowledge managing in the MRO tasks was substantiated. Using neural networks for decision making in the several MRO decision-making tasks was showed. The application of intellectual agents and multi-agent system for performance monitoring, data collection and decision making are described. The life cycle cost of the equipment formula is proposed. The tasks of optimization in MRO support and knowledge accumulation, application and reasoning by ontologies are commonly described.

1. Introduction

The current competitive environment is variable. The enterprise should constantly look for ways to reduce costs and improve productivity to be competitive. One such tool is the rational organization of the maintenance and repair organization (MRO). This paper shows the basic organization of effective enterprise equipment maintenance and repair based on a systematic approach, obtained on the basis of years of combining experience in the development and implementation of supporting maintenance and repair of software systems.

As well known the enterprise performance depends on equipment efficiency. The spetialised mechanical department of a company or the service organizations (contractors) perform the function of facilitating smooth running of the equipment. The availability of the equipment is provided by high-quality, timely and safe MRO in a case of rational use of dedicated resources.

Objects that require maintenance and repair is exist in any enterprise. This is not necessarily the productive facility. There are buildings, facilities, communications, vehicles, office equipment and office equipment and etc. All they need to maintenance indeed. The problem is relevant for organizations that are not directly involved in production too. One of the important tasks is improving the equipment maintenance and repair. The solution of this problem depends on stability and performance of each enterprise. In case of emergency incident production is stops and enterprise suffers losses. Experts estimates (Tinham, 1999) that the MRO automation significantly reduces the cost of the equipment repair, technical support, inventories volume, as well as profitability increasing. The diagnostic monitoring and maintenance automation works are results in repair costs reducing up to 50-80%, the technical support cost reducing – up to 50-80%, the inventory volume reducing – up to 30% and the production profitability increasing – up to 20-60%. In the works (Pajk, D. & Kovačič, 2013; Panorama Consulting Solutions, 2013) also a study of the ERP systems implementation effects is cited.

According to (Software Advice, 2013), the top benefits to using maintenance management software include:

  • Better recurring maintenance scheduling;

  • Better work order assignment and request management;

  • Greater access to historical reports;

  • Reduced maintenance costs.
