Intuitionistic fuzzy generalized net analysis of periodic deadlock detection in database systems

This paper presents an intuitionistic fuzzy generalized net model of a transaction database system, which uses the 2PL protocol with periodic deadlock detection. It defines probabilities for a transaction to be granted a requested lock, held back by another transaction or deadlocked, which are integrated with the intuitionistic fuzzy predicates. We can use this model to simulate transaction processing and to analyze the efficient time for useful work and the time wasted in holding back transactions.
