ABSTRACT
In a world of increasingly turbulent markets and growing technical complexity of products and production processes it is a core problem of work systems to cope with uncertainty. Many different activities are performed within work systems to deal with this problem. Temporal planning and scheduling are part of these activities, meant to cope with uncertainties that arise in matching dynamic production demands with potentially unstable production resources. This sets up some peculiarities of temporal planning and scheduling (e.g. McKay, 1987, 1992; Weth von der and Strohschneider, 1993; Schüpbach, 1994; Wiers, 1997):
• Information to be processed may be incomplete, ambiguous, dynamic and of stochastic nature.
