  • Patent number: 5128860
    Abstract: An improved method and system is described for allocating manufacturing or process resources having multiple constraints thereon to meet various time varying manufacturing or service demands having multiple parameter requirements.The demand requirements are expressed as a multi-dimensional time ordered array of vertices D.sub.q [t,r,j], for each demand q, wherein t is time and r identifies the physical requirements associated with the q.sup.th demand and j is an integer index running from 1 to J wherein J is the total number of times wherein r has differing values. The available resources are expressed as a multi-dimensional time ordered array of resource vertices R.sub.p [t,c,i] for each resource p, where c expresses the physical capacities associted with the p.sup.th resource, t is time and i is an integer index running from 1 to I where I is the total number of times wherein c has differing values.A logical system is provided for comparing R.sub.p and D.sub.q to determine when and how D.sub.

  • Patent number: 4450740
    Abstract: A rotary envelope machine blank cutter is provided with laterally adjustable, independent frame units for each meshing set of knife rolls for changing the depth of a side cut into a blank for envelope size and style production changes. The rotational and axial meshing of hard and soft knives respective to a single knife roll set is adjusted without disturbing the roll mount of either knife. Changes in envelope length or style are accommodated by the mechanical capacity to adjust the rotation cut timing between the knife roll sets of a two-set unit and also between respective cutting units of two or more two-set units. As in the case of lateral cut adjustments, knife roll mounts are undisturbed by rotational timing adjustments. Consequently, the machine may be quickly and accurately changed for production runs of any of several envelope style and several sizes respective to each style: all adjustments being made without disturbing the knife profile mesh of any knife set.
