Computational-Process Modelling of Household Activity Scheduling

Models of households' travel choices are an important focus of research. For some time it has been realized that such models need to incorporate how travel depends on activity choices. It is argued that production system models constitute an alternative or necessary complementary approach if the goal is to develop models of interdependent activity and travel choices, or activity scheduling, which are based on behavioral-science theories of higher cognitive processes. Several computational-process models (CPMs) which implement production systems as computer programs are reviewed. Currently, no encompassing CPM exists but some may be possible to integrate in a descriptive model of activity scheduling.
