In this paper, we construct fuzzy renewal processes involving fuzzy random variables. We first extend the renewal processes to the fuzzy renewal processes where interarrival times, rewards, and stopping times are all fuzzy random variables. According to these fuzzy renewal processes, we then extend some theorems of renewal processes to those in fuzzy renewal processes. These are elementary rene...

In this note, inequalities and bounds for weighted renewal-type integral equations are presented. Some upper and lower bounds for the weighted renewal-type integral equations with monotone weight functions are derived. Some upper and lower bounds for the weighted renewal-type equations with monotone weight functions are derived. Bounds for the difference between two weighted renewal functions a...

Introduction The study upon which this paper is based solicited information on school renewal from a purposive sample of principals initially identified using quantitative profiling techniques (Silcox, Cavanagh and Dellar, 2003). Principals were presented with a series of questions that enabled an investigation of their leadership behaviours with respect to school renewal. The principals' respo...
