Collaborative design method and system for parent plate and plate blank of medium plate oriented to production order combined optimization

Abstract

The invention provides a collaborative design method and system for a parent plate and a plate blank of a medium plate oriented to production order combined optimization. The method comprises the following steps: specific to a sub-plate one-dimensional combined optimization design in a medium plate production order, building an optimized control model under the consideration of the constraints of complicated production processes, equipment and the like specific to the aim of minimizing residual materials and material loss, deciding a sub-plate combination way, the length of the parent plate and the length of the plate blank, selectively coding the plate blank section of each order after orders are received, designing a decoding method based on column generation, and generating plate blank and parent plate design schemes; then, searching for a better code string in neighborhood through repeated iterations based on tabu search; and when an end condition is satisfied, selecting a current optimal code string for evaluation and adjustment, and outputting corresponding plate blank and parent plate design results lastly. A system controller controls the design processes of the parent plate and the plate blank of the medium plate according to the method. Through adoption of the collaborative design method and system, residual parent plates and material loss are reduced, and the production demand can be met better.

Description

technical field [0001] The invention relates to the technical field of metallurgical control, in particular to a method and system for collaborative design of a medium-thick plate mother plate and a slab for combination optimization of production orders. Background technique [0002] Under the order-oriented production organization model, in order to deal with the contradiction between individual needs and large-scale production, manufacturing enterprises need to design specifications and production volumes of raw materials to be produced according to production orders. For the medium and heavy plate industry, it involves There are two aspects of mother plate design and slab design, that is, to combine the small-size daughter plates in the order into large-size mother plates and slabs to be produced, wherein the mother plate is formed by rolling the slab, and the have a one-to-one correspondence. Motherboard design needs to determine the actual production specifications of ...
