for monitoring and controlling deviations in aprocess, working conditions, quality & production cost.
also for detecting damage causes, theirdeveloping mechanisms & potential failures for

It provides an overall view of the state of theproduction process and maintenance technical & economic impact on company business
It provides the basis for cost-effective andcontinuous improvement of the production and maintenance process
The results of applying TQMain have shown a big beneficial potentialBenefits and Applicability of TQMain
Benefits and Applicability of TQMain
Detecting deviations in the state of acomponent/ machine/process, production
cost, product quality and working environment at an early stage in order to control the
situation when it is possible by “stopping” or reducing the rate of the development
Selecting the most cost-effective maintenancestrategy/policy
Selecting the acceptable deterioration rate to“guarantee” no sudden failure during the lead-time
Detecting imminent failures and follow up their development and predicting the level of the CM parameter, e.g. vibration level
Assessing the probability of failure, residuallife of a component/equipment & the most cost effective opportunity for performing
maintenance action
Identifying damage initiation causes,developing mechanisms and failure modes with increasing diagnosis and prognosis precision
by relating past measurements to the damage subsequently found and safe lead-time

4 Negative impact of production process on the environment (Environmental-friendly production)
60 6% Expenses for special treating of the product when its life length is terminated, e.g. batteries. Special expenses for adapting the production to the national/international legislation on environment
5 Worse machine condition (Machine condition)
70 7% The losses due to losing some of the machines’ value, i.e. machine life length, due to rapid deterioration compared with the case when the machines are in better condition
