Medium-and-large-thickness plate unfulfilled order product production method enabling nearly no planned undesired products

Abstract

The invention relates to a medium-and-large-thickness plate unfulfilled order product production method enabling nearly no planned undesired products and belongs to the information technological field. The invention mainly aims to decrease planned undesired products during the production of unfulfilled order products. According to the method, sales orders are transformed into production orders; four operations namely, rolling, cutting, inspection, and delivery of the production of medium-and-large-thickness plates are generated; after the production is completed, steel plates are subjected toquality inspection, and orders are removed based on the quality inspection of unqualified products; when the number of unqualified steel plates meets a condition that only one plate blank needs to befed, a manufacturing execution system triggers unfulfilled order product production, at this moment, the number of planned undesired products of the unfulfilled order product production is zero; whenthe number of the unqualified steel plates which are detected out through quality inspection does not meet a condition that one plate blank in an original production order is needed, and available plate blanks exist, order unfolding is performed according to an order unfolding model on the basis of unfulfilled orders, and at this moment, the number of planned undesired products of the unfulfilledorder product production is approximate to zero; and when the number of the unqualified steel plates which are detected out through quality inspection does not meet a condition that one plate blank inthe original production order is needed, and no available plate blanks exist, production is organized through order consolidation, and at this moment, the number of planned undesired products is zero.

Description

technical field [0001] The invention belongs to the field of information technology, and in particular relates to a supplementary rolling method for a medium-thick plate in which the planned take-out product is close to zero. Background technique [0002] Carry-outs are made-to-order products that do not meet the requirements of the order or products that meet the requirements of the order but exceed the requirements of the order. During the production scheduling of medium and thick plates, the production is organized according to the thickness, width, length and number of pieces required by the order. Ideally, the number of pieces in the production plan is equal to the number of pieces required by the order and no unqualified products will be produced. In the actual process, substandard products are usually produced due to raw material defects or immature production processes. At this time, the production plan needs to be reorganized according to the order underscheduling (...
