Artelys Kalis 12.8: Solve your biggest Job shop problems!
Main new features
This new version makes it easier to solve job-shop problems (JSP). Artelys Kalis improves the modeling and resolution of optimization problems in IT and operations research where jobs have to be scheduled and assigned to resources .
On the modelling side, the user is now able to define a set-up time between two tasks requiring the same resource. For example, it is now easy to model a scheduling problem where the maintenance tasks are to be performed in different places meaning the skilled technicians required for these tasks must travel between these places.
On the resolution side, the Timetable algorithm, used for the propagation of the resource constraints for the tasks, has been vastly improved, notably for the alternative resources. As a result, the performance of Artelys Kalis has vastly improved. For example, in the case of a scheduling problem with up to 250 alternative resources as a function of the number of tasks planned, the computation time reduces as shown below:
Other new features of Artelys Kalis 12.8:
Support of Python 3 Cross-platform random numbers generation

Artelys Knitro 15.0: New Tools for Your Large-Scale Models
Artelys is pleased to announce the release of Knitro 15.0, which provides new algorithms and performance improvements to solve your large-scale optimisation problems, whether linear or non-linear, more quickly.
Artelys Introduces Future Sight: a Visualisation Tool Supporting the Energy Transition
As partner in the European Climate + Energy Modeling Forum (ECEMF) – a Horizon 2020 Europe project uniting research institutes and leading energy modellers in Europe – Artelys has contributed to modeling activities powered by Artelys Crystal Super Grid modelisation tool, and has led the development of a fully-fledged visualisation tool.
Supercharging Optimisation: How Artelys, FICO and NVIDIA cuOpt Join Efforts to Scale Up Energy System Optimisation
As energy system models continue to scale—reaching up to hundreds of millions of variables and constraints—traditional CPU-based optimisation solvers are hitting performance and memory bottlenecks. These increasingly complex models are essential for planning Europe’s energy transition, yet solving them within realistic timeframes has become a pressing challenge.

Artelys Kalis 12.8: Résolvez des problèmes de job shop toujours plus grands !
Principales nouveautés
Cette nouvelle version permet de résoudre plus facilement les problèmes de job-shop (JSP). Artelys Kalis améliore la modélisation et la résolution de problèmes d’optimisation en informatique et en recherche opérationnelle pour lesquels des tâches doivent être planifiées et affectées à des ressources.
Du point de vue de la modélisation, il est désormais possible pour l’utilisateur de définir un set-up time entre deux tâches nécessitant la même ressource. Par exemple, il devient facile de modéliser un problème de planification de tâches de maintenance localisées à des lieux différents, et pour lesquelles les techniciens compétents pour les accomplir doivent se déplacer entre elles.
Du point de vue de la résolution, l’algorithme Timetable (algorithme utilisé pour la propagation des contraintes entre tâches et ressources) a été largement amélioré, notamment pour les ressources alternatives. Des gains de performance importants en résultent. Pour un problème de planification avec 250 ressources alternatives en fonction du nombre de tâches planifiées, la nouvelle version d’Artelys Kalis permet de significativement réduire le temps de calcul :
De plus, Artelys Kalis 12.8 inclut maintenant les fonctionnalités suivantes :
- Support de Python 3
- Générateur cross-platform de nombres aléatoires
