1.前言为提高矿床勘查效率,需要尽可能大量而又低成本地获取有效,正确的情报。情报的准确度、数量和成本这三个要素具有相反的性质。例如,要提高情报的准确度,情报的数量则变少,成本增高;要增加情报的数量,则准确度下降,成本增高;要降低成太,则情报变得不甚准确,数量也减少。 1. INTRODUCTION In order to improve the efficiency of prospecting, effective and correct intelligence needs to be acquired as much and as costly as possible. Intelligence accuracy, quantity and cost of these three elements have the opposite nature. For example, to increase the accuracy of information, the number of information is reduced and the cost is increased. To increase the number of information, the accuracy is reduced and the cost is increased. If it is reduced to too small, the information becomes less accurate and the quantity reduced.
