This paper deals with online scheduling of a flexible job-shop with blocking where jobs are transported between the machines by one or several automated guided vehicles. The objective is to minimise the total weighted tardiness of the jobs. Schedules have to be generated online (i.e., jobs only...

A non-linear model is applied where suddenly strong spurts of exports occur when changes of the exchange rate go beyond a zone of inaction. We call the latter a “play” area – analogous to mechanical play and implement an algorithm describing path-dependent play-hysteresis into a regression...

An extension of process modeling languages is designed which allows representing the semantics of model element labels which are formulated in natural language by using concepts of a formal ontology. This combination of semiformal models with formal ontologies will be characterized as semantic...
