From time to time most real life job/flow shops will experience more or less severe buffer problems in relation to the operation at its various stations in the shop. Due to temporary non-predictable variations in the job flow intensity the assigned buffer space in front of a given critical station will now and then turn out simply to be quite insufficient. Unless they exercise either a consequent JIT-control system or a CONWIP set-up of some sort where the latter strictly speaking is a system with the overflow concentrated at the entrance of the production facility, this consequently leads to temporary buffer overflow situations. This paper will investigate the impact of buffer overflow on several key performance measures of relevance to the overall operation of a job/flow shop facility. Several simple job/flow shop structures will be considered in this paper including re-entrant system set-ups (a re-entrant system is a system where some of the job-routes revisit a given station more than once).
