Introducing the λ-Scale DEMATEL method: Developing the classical DEMATEL technique

DEMATEL method is a methodology to deal with complex systems. Its core process visualize structurally the graphical interrelation among some critical factors known as most important affecting on performance or decision making issues. The initial direct influence matrix in would be assessed by integer scale of 0,1,2,3,4 for "no influence" , "low influence", "medium "high and "very high respectively. Linguistically this not symmetric because that there has been no value considered term " very low influence". Additionally challenge infinity test normalized procedure. In research, it intended redefine input propose modificationto redesign method. Eventually, threshold formula presented filtering out final total matrix.
