Matrixes of Weighing and Catastrophes

An easy to apply multi-criteria technique is the Matrixes Of Weighing (MOW), but many of the professionals that use it, in their respective fields, do it in intuitive fashion. In this regard, applications are rarely reported in specialized literature, which explains how few references exist about them. One of the application areas for MOW is the handling of catastrophes, in particular the pre-catastrophe and post-catastrophe phases where a series of problems are usually handled which solution leads to a choice, which could be done by using multi-criteria techniques.The objective of this investigation is to present the MOW with multiplicative factors, and showing their application in the pre-catastrophe phase, when choosing possible shelters and in the post-catastrophe phase, by aiding to hierarchies which infrastructures to be recovered after a catastrophe.
