摘　　要：面对我国森林资源不足、质量不高的状况,研究和应用优化下锯理论实现原木最优下锯,提高木材出材率已成为缓解木材供需矛盾的重要途径之一。本文提出了以最优化技术为基础的原木优化下锯法,以最小余料为目标函数的原木优化下锯方法,采用解析法建立原木优化下锯数学模型,通过计算机辅助排样求解,得出了一种基于梯形下锯法锯切原木的优化下锯算法,为数控双联圆锯径切板优化下锯提供了数学方法和基础,并给出应用实例。In face of inadequate forest resources, establishing and applicating the optimization theory of sawing logs to im- prove timber-produced rate is one of the ways to alleviate the imbalance between supply and demand of wood resources. Based on the object function of the minimum surplus materials, a new method of optimization sawing was described in the paper. The mathematical model of logs sawing was optimally established through an analytical method . By a computer-aided calculation, an optimization algorithm based on the ladder cutting method was proposed to provide the mathematical description and theoretical basis for numerically controlled （NC） double circular saw, and application example was given.
