Towards A Global Traffic Control (Dispatcher) Algorithm - Requirements Analysis

This paper presents an analysis of the requirements of a Global Dispatcher Interface for the control of a group of lifts. The information passed to and from the interface is defined as well as the common processing which will be executed on that information in order to generate the response. Using recognised software development methods, requirements are elicited from a consideration of the significant use cases and the architectural configurations which must be supported by the interface. The analysis is presented as interaction diagrams which show the collaborations and responsibilities of the key objects of the software.
