Application of Interval and Fuzzy Analysis in Economic Modeling

摘要: In this chapter, a new approach to solving interval and fuzzy equations based on the generalized procedure of extension called “interval extended zero” method is proposed. The central for proposed treatment as an centered around 0. It shown that such proposition not heuristic nature, but direct consequence subtraction operation. Some methodological problems concerned with definition zero are discussed. resulting solution linear developed may be naturally treated number. An important advantage it substantially decreases excess width effect. On other hand, we show can used reliable practical tool well systems them. fundamentals have published in [67,68]. present generalization obtained some results.
