摘要
本文提出应用0—1规划法对原条造材进行优化设计.每一个可能造出原木段为变量xi,根据造出各种规格材累计价值为目标函数值,当满足各种约束条件时目标函数值最大的造材方案为优化方案.研究结果表明,该法在原条造材优化设计应用效果理想,具有显著的经济效益,方法简便,便予在便携式微型计算机上应用,只要输入原木价格,原条外形尺寸,等级区域,即可得到造材优化方案.
The method of 0-1 programming has been used in optimal design for tree stems bucking,in which X_i represents each possible cut log,and the accumulative value for each log from the butt to the top of tree is used as objective functions, and, when the binding conditions are met,the design that has the largest value of objective function should be the optimal one.The research shows that this method has better results when used in tree stems bucking and has significant economic benefit;and that it also has the advantages of being convenient and suitable for pocket micro-computers,by which the optimal design for tree stems bucking can easily be got if only the length and diameters of the butt and the top as well as the grade zones and the value of the log are entered.
