This paper suggests the mathematical model of prospecting decision for metal-lic ore deposits. The authors use the different cut-off grade values and several plans for the delineation of ore body, and suggest the principles for determination of the optimal plan according to the expectation value of total profit of each plan. Taking the two tin deposits-Gejiu and Yinyan as an example, the application of this model has been concretely illustrated. Finally the computer functional-block diagram is given.             本文提出金属矿产详查决策数学模型。该模型包括确定矿体品位区间的对数正态模型和确定最低工业品位的数学模型。提出了采用不同边界品位值,多方案圈定矿体;根据其期望总利润值确定最优方案的原则。并以个旧和银岩两个锡矿区的矿床为例,具体说明了该模型的应用。最后给出该模型计算机程序框图。 文摘来源          This paper discusses the adding fro fix units used to increase the aseismic reliability of lifelines network system. Through the importance analysis of added units and based on the failure related analysis under earthquake, the conceptual principle of adding frofix units are discussed. Through the estimation of the optimum decision mathematic model and based on the discreteness of lifelines arc units design plan, the practical method of adding-strength optimum design is suggested.             探计了以增设冗余单元来提高在役生命线网络系统的抗震可靠性。通过对可增设单元进行重要度分析、并考虑地震环境下的失效相关性，讨论了冗余单元增设的概念性原则。通过建立增设单元的优化决策数学模型，并利用生命线弧单元设计方案的离散性，建立了增设加固优化设计的实用方法。 文摘来源          A genetic algorithm for optimum decision on the earthquake fortification level of the lifeline system is studied in the paper. It is confirmed that the system reliability is taken as a synthesis parameter of the safety and economics. The optimum decision model of the level is built by taking the fortification intensity as the optimum parameter. It is found that the genetic algorithm is used as an optimum measure; the practical optimum algorithm is proposed.             本文以系统可靠度为安全性与经济性的综合指标,以建(构)筑物设防烈度作为优化参数,建立了生命线系统及单元抗震设防水平最优决策的数学模型。并以遗传算法作为优化手段,建立了实用优化算法。 文摘来源
