This article describes how a manufacturing system with working people can be modeled and simulated, wherein the focus is on the organizational processes of the people itself. Explanations are based on a real model, which was made for a Swiss Company producing weaving machines. The model described includes the assembly part where seven people with different qualifications have to organise their work on more than 15 different assembly stations. The software "MASTER" was used for building the model, whereas the simulation model itself runs under the discrete-event simulation language SIMSCRIPT. The modeling concept can be applied to any other simulation package which shows a certain modeling flexibility.
