Abstract
PurposeThis paper aims to deal with disaster and recovery systems, introducing the catastrophe matrix as a disaster‐preventing tool.Design/methodology/approachA new model is proposed which is proved to be a classical assignment problem. It is solved based on well‐known optimization methods. Research is presented for the danger risk of the system and a fully automated recovery system with a minimum cost is presented.FindingsResearch accepts the fact that a catastrophe has already been activated on the system.Research limitations/implicationsThe difficulty of solving the proposed model of the threat and countermeasures still remains.Originality/valueThe proposed models show a new original way to confront dangers and overcome the existing classical models based on risk management.
