We describe a methodology for optimal controller construction for chemical batch plants. The emphasis lies on the problem of running multiple batches. We consider a layered design and solution to the above problem, in particular with a lower layer realised in PLCs and a higher layer realised on arbitrary computer systems (usually PCs), such that the lower layer ooers to the higher layer a colle...

Traditional pump scheduling models neglect the operation reliability which directly relates with the unscheduled maintenance cost and the wear cost during the operation. Just for this, based on the assumption that the vibration directly relates with the operation reliability and the degree of wear, it could express the operation reliability as the normalization of the vibration level. The chara...
