Push/pull production plan and schedule used in modern refinery CIMS
Push/pull production mode used in CIMS and its application in refinery are mainly discussed in this paper. Firstly, we discuss about push/pull production mode used in CIMS, where manufacturing system is introduced, push/pull combined control strategy is put forward push/pull production mode is compared with MRPII and JIT. Secondly, production plan and schedule strategy of push/pull production mode is put forward, where its basic framework and overall architecture are given out, push/pull combined control method for main production plan is discussed. Then, production plan and scheduling system of refinery CIMS is discussed, where production procedure process, basic production characters, refinery production and administration, its activity types are introduced, a refinery integrated production plan and schedule system is put forward, its problem solving process is discussed in detail. Next, a kind of integration framework used in refinery is put forward and discussed. At the end of the paper, some conclusions are drawn.
