摘　　要：钢管、型材、线缆等材料广泛应用于各类石油工程设施的建设工程中,如何提高此类材料的利用率是实际使用过程中的一个难点和重点。型材的套料是一个典型的一维线性下料问题,下料过程中会产生大量的余料,余料的二次使用是制约材料利用率提高和降低运输及库存成本的重要因素。文章提出了一种线性材料的标准化余料信息储存方式,和材质库联动能够高效地存储和提取余料信息,并通过一种基于“余料优先原则”的算法,在实际应用案例中提高了材料的整体利用率。Steel pipe,prof iles,cables and other materials are widely used in the construction of various petroleum engineering facilities.How to improve the utilization rate of such materials is a diff icult and important point in the actual use process.The nesting of shapes is a typical one-dimensional linear cutting problem.A large amount of residual materials will be generated during the cutting process.The secondary use of residual materials is an important factor restricting the improvement of material utilization rate and the reduction of transportation and inventory costs.In this paper,a standardized storage method of residual material information for linear materials is proposed,which can eff iciently store and extract residual material information in conjunction with material library,and through an algorithm based on the principle of“residual material priority”,the overall utilization rate of materials is improved in practical application cases.
