摘要:本文依据日常生活中使用的筛子工作原理，首次提出了“智能筛”优化下料方法，使得复杂的优化数学理论问题变得直观易懂，且具有非常理想的鲁棒性。经与多个文献中使用的算例比较，优化效果十分显著。该方法应用于平法钢筋下料计算机辅助设计系统中，实现钢筋优化下料、加工、库存一体化计算机管理，在实际应用中取得了显著效果。

Abstract: This paper presents a new method called "intelligence sieve method" while gain enlightenment from the work style of a sieve, and makes the complicate optimization theory become more understandable, It presents a very simple but effective way of optimization and shows great robustness. Compare with several published papers, this method shows remarkable effect of optimization. The method has been used in the computer aided steel bar cutting system which has the functions of steel bar cutting, manufacturing, and stock managing, and shows remarkable effect.
