Abstract: An automated method optimally designs plates to satisfy an order book at a steel plant so as to maximize the yield of the plates designed while using capacity fully to reduce the production of surplus slabs or plates, and satisfy order deadlines. Our method consists of four main components: (1) mother plate design, (2) slab design, (3) cast design, and (4) material allocation. A column generation framework for mother plate design is used where the problem is decomposed into a master problem and a subproblem. The master problem is used to evaluate packing patterns that should be used to fulfill the order book and the subproblem generates potential one-dimensional and two-dimensional feasible packing patterns as candidates to be evaluated by the master problem. The solution to the master problem produces a list of mother plates that need to be produced. These mother plates are transformed into candidate slabs, which are represented via an interval graph.

A remainder portion is allocated to an intermediate position along the carcass, slab or loaf to be sliced from the carcass, slab or loaf before a butt end portion, gripped by a gripper of the slicing apparatus, reaches the slicing head. The butt end portion is pre-arranged to be the desired pre-selected portion weight or at least an acceptable pre-selected portion weight. The butt end portion can then be released by the gripper as a desired or acceptable weight portion.

The system allows for removal of a filled leading harp rack, by designating a new leading harp rack for the control system, which then dynamically adjusts the bias and associated cutting scheduling.

Abstract: A numerical procedure for simulating the behavior of incompressible, viscous fluid in a casting/molding process. The method is based on classical fluid dynamic equations and uses control volume-finite element and numerical techniques to solve the momentum and energy equations to obtain solution for the variable parameters. The method incorporates five additional modules which simulate fluid flow in the shot sleeve, heat transfer between the die and the heat transfer fluid, die cooling by lubricant, formation of mend line. These additional simulation modules produce realistic boundary conditions, and replace many of the assumptions that would have to be made, to solve the governing equations. These added improvements ensure a faster convergence of the numerical solution and a more realistic simulation of the die casting process.

Abstract: A pattern solution set for paper roll trimming to fulfill orders is generated using constraint programming and a heuristic. For every pattern generated, an objective function is evaluated based on the sum of waste factor and the variance of the quantity ordered for all widths in that pattern. The pattern that has the least objective function is chosen with the maximum number of sets possible. Orders are updated with the quantities left over and then the process continues, forming a solution tree, which serves as an initial solution set. The initial solution set is checked individually against the average loss of the solution set. Nodes in the solution tree having trim loss greater than the average loss are identified. Branches of the tree emanating from its parent are explored for better patterns. The process continues until all patterns are below the initial average loss.
