Product operation and joint interval valued observable

Abstract

The aim of this paper is to define the product<br />operation on a family of interval valued events and the notion of<br />joint interval valued observable. We show the connection between<br />product operations for interval valued events and intuitionistic<br />fuzzy events, too. We display the relation between joint interval<br />valued observable and joint intuitionistic fuzzy observable. We<br />define a function of several interval valued observables with help<br />of a Borel function and a joint interval valued observable, too.
