Abstract:
In the area of industrial control systems, the choice between custom made (CM) electronics and the use of commercial of the shelf (COTS) components is often not trivial. Especially, when required quantities or specific requirements do not give a clear sign for selection. From a pure cost point of view (development costs and product costs) a decision might look trivial, but a broader view helps to perform an sound decision. In this work, decision criteria and a decision method are presented for industrial control systems targeting COTS devices, CM devices or a combination of both. Moreover, a case study with three industrial control systems is presented showing the application of the approach.
