In the paper , the methods how to manage the raw material fields is devoted . accord to the wuhan iron and steel ( group ) co . industrial port " s level , with operation research , physical distribution , computer technology how to deal with transport , loading or unloading stockpiling advance an idea . in the paper , the raw material fields " physical distribution system is departed to three part : optimum burden , the best line , loading and unloading advance , step by range and step by level , its can be implement so as to improve the product ' s competition ability 本课题的研究内容主要是原料场混匀配料及作业线系统优化，它包括配料计划的选择及作业线选择、料场的货位及贮量的合理配置等几项的综合优化，是一个比较大的物流系统的规划。主要以武钢工业港原料场为例证展开研究的。配料计划的优化是以可以降低成本并保证成份控制为目标进行线性规划的。
( 5 ) through using value engineering to optimize the mining technology in the material field , this directly reduced the requirement of engineering geology condition of mining block stone , and raised mining rate of stone in the material field , and then reduced the cost of production of armor stone by 394 . 4 thousand ( 5 )应用价值工程对料场的开采工艺进行优化，降低了开采块石料对料场的工程地质条件，提高了料场的块石采取率，进而为护坡块石料的生产降低成本39 . 44万元，取得了较大的经济效益。
( 3 ) according to the actual geology situation in the material field , use the " alternation " principle of the value engineering analysis methods , and then find a better construction method to satisfy the requirement of rock - fill material , through using chamber blasting to substitute muffling and using an - fo to substitute ammonium nitrate explosive , and then huge economical benefits were gained , for example , the unit cost of its rock - fill material reduced from 11 . 77 m3 to 7 . 17 / m3 , and directly reduced the total cost by 4 . 26 million of cost ( : 3 )依据料场的实际地质情况，通过价值工程活动，利用价值分析的“代替”原理，在满足堆石料功能不变的条件下，采用洞室爆破代替深孔梯段爆破，采用按油炸药代替钱梯炸药，使得堆石料的开采成本显著降低，从投标价的h . 70元/ m3降低到7 . 17元/ m3 ，降低了4 . 53元/ mj ，以上坝堆石料94 . 2万m “计，直接降低成本426 . 75万元，产生了巨大的经济效益。
