Reengineering can be described as thoroughly redefining and radical business transformation to improve key parameters (deadline, price, quality). It is an important concept in the implementation of major organizational changes in maintenance. Maintenance of technical systems, as a function and a part of the production process occupies today an important place in the production system of every company. On the development of maintenance affected rapid industrial progress, as well as a steady increase in automation and integration of resources for the work, and sharp rise in fixed costs in relation to variable. Maintenance is defined as the permanent control of all means of work, as well as making certain repairs and preventive actions aimed at constantly, functional training and keeping the production equipment, facilities and other devices. Term “maintenance” comes with each term “production of certain goods”. Over the time and use leads to the aging of materials and capital equipment, the technological efficiency is reduced, and comes up to the evident technological obsolescence. Work tools are spended over the time and their ability to work is reduced. Work tools are subject to failures, fractures and damages, so it comes to the work disruptions. This causes the appearance of the costs for the replacement and repair of the parts, as well as costs due to delays in the production process. Therefore, it is important to maintain in order to increase the quality, prevent delays in the production process and thereby delay the finished products and reducing the costs of downtime.
