Knowledge Management and Big Data

1. Maintenance is the set of actions taken to maintain the proper functioning of the product (device, machine, structure, software, etc.). There are differences between planned maintenance and frontal maintenance:

· Planned maintenance Scheduled maintenance - Maintenance according to predetermined rules, in order to prevent mishaps. The main purpose of planned maintenance is to avoid equipment failure before it actually occurs. This maintenance includes Preventive Maintenance: Maintenance done Bmroohizmn constant (eg one year) or after a certain usage level (for example, for a thousand hours of operation), which are replaced or refurbished parts of the product, although they are still functioning (but is estimated by the manufacturer probability Their spoils are too high( In order to prevent mishaps.

This includes testing, adjustments, scheduled service and shutdown planned. Standard maintenance tests are scheduled, this can help increase the life of assets and reduce the need for partial repair.

Predictive maintenance - is a maintenance-based forecast which is designed to help determine the state of equipment in the service to assess when to perform maintenance. This approach ensures cost savings for preventive or routine maintenance based on time, because tasks are performed only when justified.

Forecast maintenance refers to the entire organization's activity, not just computing. At the same time, the concept of its derivatives also applies to the world of computing. This is first of all about the severity of its components, but also the software and development world, in which possible bugs are addressed. The main trends seen in this area include new and sophisticated diagnostic tools, the strengthening of analytics, sensors and IOT , the expanding supply of services, and a series of trends,.

1. A complex system Is a system that contains a large number of components that affect each other. Complex systems may by definition introduce complex and highly irregular behavior, in which it is difficult to predict what a specific component will do over time, although at specific intervals a complex system may also exhibit relatively simple behavior.

An example of a complex system is an air conditioner used to ventilate, heat and cool the room. The system can perform a number of actions in personal adjustment or automatically like a room temperature until it reaches the desired temperature. The system consumes a lot of energy and sometimes runs for extended hours and requires maintenance accordingly.

In order to perform maintenance we will need to know when the air conditioner has been used , how often it was used and where each part was last replaced. Also, to save data on air conditioners are the same in order to make comparisons and that we can do Lhzotcmh use every part and replace it before that comes the failure of his. Also, the air conditioning load should be predicted by sensors that measure energy consumption in order to assess in advance when we will reach a failure of each part and take care of spare parts accordingly.
