摘要:

We present a knowledge—based multiobjective project scheduling system which handles a class of nonpreemptive scheduling problems characterized by (i) renewable, nonrenewable and doubly—constrained resources of many types, (ii) multiple performing modes of tasks and (iii) multiple project performance measures. Knowledge concerning different aspects of technology, resources and schedules is stored in several knowledge sources which are separated and communicate through a blackboard. The knowledge is represented by production rules and frames. Rules operate on objects (represented by frames) which instances are stored in the blackboard.

摘要:

Computer programs are becoming more and more complex and voluminous in most firms. This raises the cost of maintenance. To minimize this cost, qualities must be given to computer programs that assure them a good evolution: reliability, efficiency, flexibility, conformity, … This cost minimization must be preceded by a diagnosis that allows the measuring of the effort required to achieve this aim and recommends actions to be undertaken. In recent years a lot of static quality analysis software has been created. The tools used do not determine the final required characteristic, but simply measure indicative variables such as the complexity of the text, of the structure, … As these tools only each offer a fragmentary aspect of quality, we suggest a quality analysis based on metrics but supplemented by “checklists” covering all the quality criteria of the programs and taking into account the semantic aspects which are not covered by the static analysers. To implement these checklists we propose a knowledge—based system which integrates both semantic and syntactic aspects. Besides the software quality evaluation, the system helps to improve this quality by emphasizing the most penalising quality criteria for the program under review. Given this information, programs could be up graded and their maintenance cost reduced, liberating the human resources necessary to develop new applications.

摘要:

GAET is a software for automatic generation of university—like timetables. The method we propose here is based on the simulated annealing algorithm with Geometric/Constant/Temperature cooling schedule type.
