These characteristics can be used well to describe the convergence properties of sequences of fuzzy valued measurable functions and K-quasi-additive fuzzy number valued integrals.

All uncertainties and disturbances are not required to be constants. They may be bounded by some known functions of states and external measurable variables.

Road function is the cut-in point of my research, so it is important to look for measurable indexes, which can distinguish those different road functions.
