Discussing fundamental modeling tools, queuing theory, and discrete event simulation for evaluating production systems, this book presents a development environment for discrete event simulation in a language easy enough to use but flexible enough to facilitate modeling complex systems. Incorporating the use of discrete simulation to statistically analyze a system and render the most efficient time sequences, designs, upgrades, and operations, this new edition develops new visualization graphics for DEEDS software, includes improvements in the optimization of the simulation algorithms, and adds a chapter on queuing models.
