Talk strategy will directly affect the availability of equipment, maintenance costs, safety and environmental protection, will also indirectly affect the company's reputation, it will directly affect the economic efficiency of enterprises.

　　The reason is simple, there is no preventive maintenance policy of the enterprise, equipment unplanned downtime frequently will not only affect the delivery commitment, but also reduce maintenance efficiency, increased risk of damage to equipment chain for process purposes, but also affect the production of downstream equipment , the loss is even greater.

　　Maintenance strategy formulation, first consider the average age of equipment. In general, the failure rate level is divided into initial failure period, sporadic (random) failure and depletion of failure of these three stages,Each phase should have a maintenance strategy for each stage, which in previous chapters have been described, it is not expanded.

　　Maintenance mode means that maintenance microscopic strategy design. Maintenance of strategic relationships to each micro-specific device, or a part of the device. The following maintenance mode is often used micro-enterprise maintenance strategy.

　　After the maintenance: refers to the equipment failure after repair. Applicable to the fault is not serious, not cause damage of equipment chain, do not harm security and the environment, will not make the production before and after the link congestion, equipment downtime losses small fault after repair. Afterwards, can maximum limit to extend the effective use of equipment maintenance cycle, is the economic maintenance strategy. Factory don't think that, because the device is out of order, after the maintenance is inevitable, so he will later maintenance as an optional maintenance strategy. Instead, after the maintenance should be enterprise take the initiative to a strategy design, that is to say, some equipment or parts, we never do preventive maintenance, only do later maintenance. If the lighting system as a device, the enterprise has never to do this kind of equipment preventive maintenance.
