Machine-job incidence matrix based analysis of manufacturing systems in time domain

This paper presents an extension of previously introduced method for manufacturing systems analysis and design based on so called Machine-Job Incidence matrix. Static model of a manufacturing system is augmented by introduction of timed machine-job incidence matrix that is comprised of operational times required for jobs in the system to be completed as well as times required for setting-up of resources upon completion of requested tasks. The proposed dynamic model has been validated by simulation of free-choice multiple reentrant flow line. Results presented in the paper demonstrate efficiency of the model.
