Paper Abstract

This paper proposes a multi-activities scheduling algorithm based extended space-time prism under time geography framework. This algorithm aims to schedule multi-activities from different kinds of activity, which can be used as kernel function of an innovative location based service-multi-activities scheduling service. The extended space-time prism is derived of space-time prism concepts of time geography. For each available activity opportunity in this extended spacetime prism, two new shortest path trees are computed to measure the travel time between activities from different kinds of activity, one new space-time tree arrive at this available activity opportunity, and the another one departs from this available activity opportunity. A prototype 3D space-time environment is implemented to support the concept of extended space-time prism, and provide function of this proposed algorithm. An example of multi-activities scheduling scenario is shown to demonstrate the usefulness of this proposed algorithm for this location based service. Finally, several future works are also introduced in this paper.
