说明：  该LINGO程序的功能是：求出工程项目的收益的净现值和每道工序的最优开工时间，约束条件是紧前紧后约束，以及资源约束。。。(The program' s function is LINGO: the project proceeds to derive the net present value of each procedure and the optimal start time constraints are tight after the former tight constraints, and resource constraints. . .)

//给定整数n，产生所有[2n]上的匹配（matching） //将其视为一个所有块大小均为2的集合分拆 //以a_i表示其第i个元素所在的集合号 //输出格式为 a1 a2 a3 ... //满足 //a_{i+1} <= max { a1,a2,...a_i } + 1 (//a given integer n, have all [2n] on the matching (matching)// will be considered as an all pieces are two sets of a split// a_i said in its i elements of a collection of lies// output format for a1 a2 a3 ...// meet// a_ i (a))
