In many cases the functionality and performance of flow-shop production systems

depends heavily on the selection of a suitable sequence of orders. The main

objectives of order sequencing in production systems are minimization of set-up

times, continuous and optimal use of capacities, reliability of delivery,

minimization of stock and throughput time as well as avoidance of undue system

states. We are going to investigate this system based on maximum number of production

when we have q-step windows and compare it with condition that we have just one

window. So we compare these factors: throughput, average delay time and other

factors like completion time, service time, number of parts in buffer and so on.-In　many　cases　the　functionality　and　performance　of　flow-shop　production　systems
