Really Ageing Systems Undergoing a Discrete Maintenance Optimization

چکیده
In general, a complex system is composed of different components that are usually subject to maintenance policy. We take into account systems containing under both preventive and corrective maintenance. Preventive considered as failure-based model, where full renewal realized after the occurrence every nth failure. It offers an imperfect each repair deteriorates component or lifetime, probability distribution which gradually changes via increasing failure rates. The reliability mathematics for unavailability quantification demonstrated in paper. process involving maintenance, arises from new corresponding cycle, designated real ageing process. Imperfect results unwanted rise function, can be rectified by properly selected policy; i.e., replacement respecting cost number n decision variable, whereas objective function optimization paper describes method finding optimal policy given constraint. variable optimally set possible realistic modes. focus on discrete one several mode(s). fixed value determines single mode, well mode. demanding terms computing time because, if contains k components, all having three modes, we need evaluate 3k configurations. shown with two adopted literature.

Protein modification and maintenance systems as biomarkers of ageing
Changes in the abundance and post-translational modification of proteins and accumulation of some covalently modified proteins have been proposed to represent hallmarks of biological ageing. Within the frame of the Mark-Age project, the workpackage dedicated to "markers based on proteins and their modifications" has been firstly focused on enzymatic and non-enzymatic post-translational modifica...

متن کاملRepairable systems availability optimization under imperfect maintenance
This paper deals with the modeling of a preventive maintenance strategy applied to a single-unit system subject to random failures. According to this policy, the system is subjected to imperfect periodic preventive maintenance restoring it to ‘as good as new’ with probability p and leaving it at state ‘as bad as old’ with probability q. Imperfect repairs are performed following failures occurri...
متن کاملA Robust Control Design Technique for Discrete-Time Systems
A robust state feedback design subject to placement of the closed loop eigenvalues in a prescribed region of unit circle is presented. Quantitative measures of robustness and disturbance rejection are investigated. A stochastic optimization algorithm is used to effect trade-off between the free design parameters and to accomplish all the design criteria. A numerical example is given to illustra...
