An intelligent layout optimization algorithm for shipyard assembly yard

Abstract

The invention relates to an intelligent optimization layout algorithm of a shipyard general assembly site. Including; The basic data model for the dispatching and management of the general assembly site: dock site, ship type data, general assembly plan, loading network, crane data and hoisting time; Establish the constraint conditions with site rules, logistics logic and process flow as the main factors; Based on the basic data model and the corresponding constraint conditions, a general assembly plan equilibrium optimization algorithm is established to form a general assembly site layout optimization scheme and a crane plan optimization scheme. It provides theoretical and algorithm basis for independent research and development of digital management system of general assembly yard scheduling and simulation optimization of general assembly yard scheduling, and lays a foundation for realizing fine management of general assembly scheduling, improving production efficiency and realizing balanced and continuous shipbuilding of shipyards.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to an intelligent layout optimization algorithm for a shipyard general group site. Background technique [0002] The dock is the core resource of the shipyard, and the efficiency of the use of the dock directly determines the economic benefits of the shipyard. As the direct supplier of the loading resources of the dock, the general group site's management effectiveness directly determines the loading efficiency of the dock. There are many factors involved in the site management of the general team, and there are many mutual influences among them. Obviously, traditional methods cannot effectively handle such a large amount of information, and can only be managed in a relatively extensive way by "grasping the big and letting go of the small"; [0003] At present, in most shipyards, the competent department or the loading department has set up a dispatching team composed of multi...

Problems solved by technology

[0004] 1) Extensive and passive management cannot promote the improvement of comprehensive production efficiency

Due to the large number of sections of the general group site, the large variability of plans, and the lack of means of visualization and information sharing, the randomness and blindness of site layout and crane resource scheduling (hoisting sequence, coordination of multiple cranes) are relatively large , so the segmented scheduling management of the multi-product general group site based on the manager's experience alone can no longer adapt to lean shipbuilding methods such as modern shipbuilding energy saving, emission reduction, cost reduction and efficiency increase;

[0005] 2) Insufficient emergency handling capacity

For multi-batch continuous production, the traditional site management mode of the general team, if there is a problem in a certain link, the current site allocation cannot be actually implemented. Accumulation, orderly management gradually becomes disorderly management, and finally becomes extensive random management, which cannot guarantee the efficient use of resources

[0006] With the development of digital shipbuilding technology, most of the leading domestic shipyards have applied computer software systems to the process of ship production management. However, the use of general group sites is almost always in a state of no quantification, no refinement, and no comparison. As a result, the efficiency of carrying operations cannot be improved
