Objectives and Approach

PONTIFEX is developing an object-oriented decision-support framework for handling routing and scheduling problems, along with specific case studies in aircraft rotation and scheduling and the physical distribution domain. The integration of advanced operations research algorithms, knowledge representation methods and user interface management techniques is providing an innovative approach to this class of problems.

Progress and Results

Several prototype applications have been built with the aim of focusing on real user requirements, testing different technical approaches and software architectures, and identifying the most suitable development/deployment environment. These developments have resulted in a flexible application model that clearly separates a reusable skeleton, or framework, from specific domain knowledge and algorithms.

As part of the framework, mechanisms for handling data consistency, encapsulating software modules, and specialised user interface objects have been developed. The toolset of modules includes innovative methods for solving temporal constraint satisfaction problems, as well as clustering and routing algorithms.

The PONTIFEX software runs on Unix workstations under the Motif graphical interface, and is written in Prolog and C.

The following major deliverables are being completed:
