The book "Simulating Continuous Fuzzy Systems" by James J. Buckley offers a comprehensive examination of the simulation of continuous fuzzy systems. It is divided into two main parts: the first part includes introductory chapters, while the second part addresses applications. The authors expand the research on fuzzy systems, which was previously focused on discrete events, and present a model based on queuing networks. These systems are capable of simulating various real-world scenarios, such as machine workshops, emergency rooms, and project networks. A central concern of the book is the consideration of uncertainties in the parameters used to calculate system descriptions. By using fuzzy numbers, uncertainty in the models is taken into account, leading to more realistic results. The book is aimed at professionals and students who wish to engage with the theory and application of fuzzy systems.
