THE HOUSEHOLD ACTIVITY PATTERN PROBLEM - GENERAL FORMULATION AND SOLUTION

The household activity pattern problem of analyzing/predicting the opt imal path of household members through time and space as they complete a prescribed agenda of out-of-home activities is posed as a variant o f the pickup and delivery problem with time windows. The most general case of the model includes provision for vehicle transfer, selective a ctivity participation, and ridesharing options. A series of examples a re solved using generic algorithms. The model is purported to remove e xisting barriers to the operationalization of activity-based approache s in travel behavior analysis.
