Documentation et rapports de validation

Introduction

Les ingénieurs et les scientifiques sont, de nos jours, de plus en plus épaulés par de nombreux outils logiciels scientifique et d’ingénierie. Ingénieurs et scientifiques utilisent donc des logiciels développés en dehors de leurs propres compagnies. En conséquence, nous en venons à nous poser un certain nombre de questions avant de choisir un outil logiciel d’ingénierie:

- Est-il précis et comment ceci peut-il être vérifié?

- Est – il correctement documenté?

- Aura-t-on accès à un bon service aussi bien technique que de mise à jour?

- Dans le cas d’un dysfonctionnement du logiciel, l’utilisateur aura-t-il une bonne assistance en cas de difficulté?

Toutes ces questions sont importantes. Cependant, la première constitue une question cruciale, puisqu’elle fait rentrer en ligne de compte la sécurité et l’intégrité de l’étude ou de la conception. La seconde pose le fondement de l’utilisation du logiciel, en termes de compréhension du sujet et de bon usage technique de l’outil. En d’autres mots, un bon logiciel scientifique, ou de conception, se doit d’être correctement documenté et d’être validé. Ceci implique nécessairement que le producteur de logiciel est compétent et a les ressources nécessaires pour effectuer et documenter ses essais de validation de logiciel.

Les ingénieurs et les scientifiques de SES conduisent leur propre R&D et offrent des services de consultation très avancés. Cette unique combinaison permet à SES de développer des applications orientées vers le monde industriel et de se maintenir à la pointe de la technologie. Les différentes publications diffusées dans les grandes revues scientifiques et publiées par les scientifiques de SES, sont autant d’indications de perception qu’a la communauté scientifique sur SES. Depuis plus de 20 ans, SES continue d’être leader et pionnier dans les problèmes de développement de système de mise à la terre et des champs électromagnétiques.

Les descriptions suivantes indiquent tout le travail réalisé par SES pour s’assurer que le logiciel CDEGS répond aux exigences des quatre questions précédentes et s’assurer d’être en phase avec les deux première.

De nombreuses publications scientifiques, ainsi que des comparaisons avec des solutions analytiques, ont permis depuis plus de20 ans à valider le développement des logiciels. La validation des logiciels conduit par SES est publié au travers de centaine d’articles dans les plus grandes revues internationales.

Chaque module d’ingénierie a été testé pour s’assurer de produire le bon résultat, dans une large majorité des cas et documentés en interne à SES. Ces résultats sont également disponibles pour l’utilisateur à partir du CD-Rom. Ces cas sont testé à chaque changement de version du logiciel et comparés aux résultats existants. En d’autres termes, chaque nouvelles versions est testé en suivant un cheminement de trois mécanismes de documentation :

- Essais sur le terrain et tests expérimentaux

- Comparaisons avec les publications scientifiques

- Comparaisons avec d’autres outils réalisant les mêmes tâches, mais basés sur des technologies différentes

Essais sur le terrain et tests expérimentaux
