Abstract:

In fire fighting, the time and effort required to control a fire increase if the beginning of the fire containment effort is delayed. Several demand-covering models have been proposed for the deployment of available fire-fighting resources so that a forest fire is attacked within a specified time limit. This paper considers the problem of scheduling a single fire-fighting resource when there are several existing fires to be controlled using a model specific to the fire's rate of spread. The problem is tackled using the concept of deteriorating jobs, that is, the model represents increasing value loss as fires remain unsuppressed and increasing time for fire suppression.

Plus on tarde à intervenir, plus le temps et les efforts requis pour maîtriser un incendie augmentent. Plusieurs modèles de demande ont été proposés pour déployer les ressources disponibles aux bons endroits de telle sorte qu'un incendie de forêt soit pris en charge à l'intérieur d'une limite de temps déterminée. À l'aide d'un modèle approprié du taux de propagation du feu, cet article aborde le problème d'allocation d'une seule ressource lorsque plusieurs incendies doivent être maîtrisés. Le problème est abordé à l'aide du concept des tâches détériorantes, c'est-à-dire que le modèle détermine la perte de valeur qui augmente tant que les incendies ne sont pas supprimés et la durée croissante des interventions requises pour les supprimer.[Traduit par la Rédaction]
