Previous research by the author has shown that the main cause of system unreliability is operator unreliability. There are three main ways to deal with operator unreliability viz improve the environment, enhance the operator′s skill and increase his motivation. Of these, the last is the final untapped area for achieving significant gains in system reliability. Moves to do this by means of competitions for operators at both a local and international level are discussed, with a description of the successes so far.展开更多

The mechatronic and electronic equipment components are mostly affected by obsolescence. A new challenger unit possesses identical functionalities, but with higher performances. This work aims to find the optimal number of components which should be replaced by new-type units, under budgetary constraints. In this work, the new challenger unit is characterized by lower energy consumption and the optimization steps are based on genetic algorithm (GA). The result shows the importance of this type of replacement in order to economize energy consumption and to deal with obsolescence.展开更多
