The queuing theory machine interference model: use and application

Abstract This paper aims at making the queuing theory machine interference model a usable tool for process designers, production managers, and others who face decisions regarding the number of machines and the size of crew to operate/maintain them. The model is presented conceptually and compared with other existing models. Next, the model is analysed, and parameter calculations are detailed: a ready-to-implement procedure is given to carry out these calculations. Finally, the use of the model and its application in the work-study context are illustrated by examples.
