Objectives and Approach

The objective of this project was to develop knowledge-based tools for process planning and workshop scheduling, based on a non-linear process plan representation. "Non-linear" means that the process plan comprises alternative and parallel sequences of manufacturing operations.

The system was to support the generation of non-linear process plans from a workpiece model and a workshop model. It will also generate a schedule, taking into account information contained in the non-linear process plans. Rescheduling will allow a sufficiently fast and flexible reaction to unexpected events in the workstation during schedule execution.

The principal tasks were to develop:

The development is focused on small and medium-batch production in the metal-working industry.

Exploitation

To ensure that the project results can be rapidly exploited, the general requirements of the market were considered in the very early phases of the project, and software engineering tools and programming languages were used that will ensure easy portability to a wide range of hardware and software environments at users' sites.
