Today’s complex machines are valuable assets and crucial for modern, effective production processes of companies. A detailed understanding of the performance of these machines is therefore of outstanding importance both for users and for producers of machines. When users measure the performance of machines they monitor the work of the machine not in an isolated environment but within the local and sometimes changing environment. Their own specific production processes constitute an important part of this environment their machine works in. In the context of production the most simple and accessible performance measure is the time it takes to achieve a predefined amount of process output. Consequently, in many cases the machine performance is computed by the most basic definition of performance: the ratio of achieved work during the whole process divided by the time used for this process.
