This paper presents the importance of obtaining the application of a maintenance technique that satisfies in a precise way the different needs of the production process, independently of its technical complexity or difficulty of access to the industrial plant facilities. This is the case of the plants with a high automation level or wind farms located in remote places with low accessibility. Besides this, the studied situations have in common the low level of physical operation in its production process.
Added to the difficulty of application of the different maintenance techniques in an optimal way at a reasonable economic cost, there is the difficulty of doing it in complex industrial facilities. In this regard, there appears the need to find a suitable technology which allows reducing the possibilities of an inadequate maintenance, by exceeding in the accomplishment of the activities as for the lack of the same ones, Alsyouf (2009). This way the consequences of important economic losses would be avoided without generating safety risks, environmental risks or risks in the working system. Two examples of this type of facilities are industrial plants with high automation level and flexibility with limited physical operation or facilities placed in locations with a difficult access. Robotized plants or wind farms are examples of both. Currently, the advances are grater regarding the efficiency and productivity of this type of assets. An inadequate plan of maintenance may reduce their performance. Therefore, these inadequate plans should be reduced. For assets under study in this paper the key point resides in detecting the failures when they give some type of indication about whether they are going to take place. Then it is possible to study the trend over the election, measurement and monitoring of some relevant parameters representing the good operation of the facility under analysis. The parameters can be temperature, pressure, vibration, linear velocity, angular speed, noise level, thickness, dielectric strength or oil viscosity. Continuous monitoring allows for a historical record of the characteristic in analysis, Lee (2008), and turns out being extremely useful for repetitive failures. Also, this system operates on goods while they are working without having to move them from their location, while allowing use of time without causing production losses associated that stops represent.
