Abstract

A vehicle space where vehicles move around is structured in a space tree whose nodes are space objects. Higher-level objects denote broader area than lower level ones. Each vehicle first decides a broad path which includes higher-level objects, and the path is made more detailed as the vehicle is approaching to the destination. Vehicles are modeled as transactions which hold objects. There are kinds of vehicles, on three points, removable, stoppable, and retreatable. In this paper, we discuss three schemes, i.e. close, semiopen, and open ones for locking and releasing objects with respect to types of vehicles.
