This booklet accompanies a software package called SimQuick.
SimQuick is a freely-distributed Excel spreadsheet (with macros) for building simulation models of processes: waiting lines, supply chains, manufacturing facilities, and project scheduling.
SimQuick is easy to learn, easy to use, and flexible in its modeling capability.
Recently updated (2016), it has been used in industry and in educational settings since 2001.
If you can open an Excel spreadsheet on your computer (PC or Mac), then you can immediately use SimQuick.
