Abstract

The invention provides a method for realizing spatial arrangement scheduling of a curved section of a chip, and the method comprises the following steps of step 1, primarily planning the scheduling of the curved section of an entire field, and formulating an arrangement sequence of the curved section; step 2, acquiring a geometric graph of the curved section and a geometric graph of a field border, determining whether the curved section is collided with other curved sections and the field border in the field, and acquiring possible arrangement schemes of the curved section in the field; and step 3, screening the possible arrangement schemes to finally determine an arrangement position of the curved section in the field, and generating a spatial arrangement allocation scheme of the curved section. On the premise of satisfying the real production of the ship, the spatial arrangement scheduling method facing towards the production of the curved section and based on an inspiration-type rule is established, and the spatial arrangement scheduling theory and method of the curved section can be filled and completed.

Description

technical field

[0001] The invention relates to the field of manufacturing technology, in particular to a method for realizing segmental spatial layout scheduling of a curved surface of a ship. Background technique

[0002] The construction of a ship is a welding assembly process of a large number of segments. If the segments are classified according to their geometric shapes, they can be divided into straight segments and curved segments. The curved surface segment mainly includes the bow and stern of the ship. Its geometric shape is complex, and the production process needs to be limited by the site area, processing personnel, and manufacturing equipment. In the existing technology, the planning and scheduling scheme formulated by dispatchers based on their personal experience cannot meet the production scheduling needs of a large number of segments, resulting in the inability to improve production efficiency, which eventually leads to it becoming a bottleneck link in the ...
