滇池地区磷资源开发研究工作中,用系统工程方法将系统分解成各种目标,拟出统筹图,使全系统各专业研究工作有序地同步进行。在行业上,由矿山到加工进行纵向研究,在层次上从矿区到全国进行横向比较,用线性规划方法纵横综合评价,以全国投入最小择优,作出开发规模等项决策。 Phosphorus resources in Dianchi Lake area of ​​development and research work, the system engineering methods will be broken down into various objectives of the system, to draw a plan, the system-wide professional research work in an orderly manner. In the industry, from the mine to the processing of longitudinal research, at the level from the mining area to the country horizontal comparison, using vertical and horizontal linear programming method comprehensive evaluation, with the minimum investment in the country to make the decision to develop the scale and other items.
