The BBC interactive videodisc is briefly described. Its utility as a geographical information system with potential applications relevant to planning is subject to a critical examination. It is concluded that the principal value of the Domesday system is as a pointer to possible future...

The purpose of this paper is to discuss the development of an integrated decision support system that will permit planners to address the multiobjective nature of the site-screening process. This decision support system will consist of three distinct decisionmaking technologies: a geographical...

A generalization of the travelling salesman problem is introduced. Each node has an associated reward, and a penalty is incurred by travelling between nodes. In the multiobjective vending problem, the subset of nodes and associated tour which will minimize penalty and maximize reward is sought....

The concept of location coverage was first applied in the location set covering problem and then extended to the maximal covering location problem. Both of these problems were set in a deterministic framework in which the presence of a service site within the time or distance standard...

Within the context of multilevel siting models, location analysts have long known the problems associated with providing access to a hierarchy of services. Numerous studies, for example, have documented the fact that locational goals at any level of an organization can be constrained by previous...
