Random fuzzy alternating renewal processes
Random fuzzy theory offers an appropriate mechanism to model random fuzzy phenomena, with a random fuzzy variable defined as a function from a credibility space to a collection of random variables. Based on this theory, this paper presents the results of an investigation into the representation of properties of alternating renewal processes that are described by sequences of positive random fuz...
متن کاملRandom fuzzy delayed renewal processes
In renewal processes, fuzziness and randomness often coexist intrinsically. Based on the random fuzzy theory, a delayed renewal process with random fuzzy interarrival times is proposed in this paper. Relations between the renewal number and interarrival times in such a process are investigated, and useful theorems such as the elementary renewal theorem, Blackwell renewal theorem and Smith key r...
متن کاملSome properties of fuzzy alternating renewal processes
The alternating renewal process is one of the renewal processes in renewal theory. It is widely used in inventory systems and queueing systems. In classical alternating renewal processes, one of the assumptions is that the on times and off times are independent random variables. The notion of a fuzzy set was introduced by Zadeh [1] who defined it as a generalized characteristic function. Recent...
متن کاملValue-based decision model for renewal processes in software maintenance
This work is based on a retrospective analysis of a renewal process applied to a very aged, highly degraded software system. Some parts of the results are generalized to define a method for determining the technical and economic qualities of software system components. The work also presents a decision model for identifying the most suitable renewal process to be applied, based on the quality o...
