二维优化排样在工程应用领域中应用范围非常广泛,尽管人们对排样问题进行了大量研究,并取得了一些成果,但一直没有找到通用的、标准的解决方法。随着各种优化算法的改进和各种二维优化排样软件不断完善,排样结果越来越理想,在一定程度上满足生产实际的需要,但单纯局限于依靠某种算法的提高或改进来解决二维优化排样问题还不能完全满足实际应用的需要。介绍了二维优化排样在实际应用中遇到的问题,进而提出了一种应用数据库技术和二维排样软件来综合优化二维排样,以期在实际生产应用中,在总体上提高材料的利用率,从而有效控制生产成本的目的。二维优化排样系统的构成及其作业流程也在文中作了详细介绍。

2-D optimum stock layout is widely used in engineering field.Though people have done a lot of research on the stock layout problem and made some achievements,they can't find a general and standard way to solve it yet.With the improvement of all kind of optimum calculation and continuous perfection of 2-D optimum stock layout software,the result of stock layout becomes more and more ideal,to some extent,it can meet the practical needs of production.However,simply depending on the improvement of some caudation or solution of 2-D optimum stock layout can not fulfill the needs of production completely.It has also been testified on practice.This thesis tries to find a way to solve it as a whole.It introduces the problems which happen in the course of its application and therefore,it puts forward a technique that using database to synthesize the algorithm for the nesting of 2-D parts in 2-D sheets so that it can improve utilization ratio of the materials and sequentially reach the goal of controlling the productive cost.It gives the detailed introduction of its composition and operation process.
