The purpose of engineering project control system decision is to obtain an optimum method . to evaluate a project schedule should consider comprehensively the technology and economic indexes , which conclude time , cost and resources . however , it is not reached in theory and in practice 工程项目控制系统决策以网络计划的优化为依据寻求最优方案，衡量一项计划方案的优劣，应该综合评价它的技术经济指标，包括工期、成本、资源消耗等，但是目前还没有一个能全面反映这些指标的综合数学模型用以作为评价最优计划方案的依据。
At the same time , a new decision - making method which determines the indices weight on the basis of the subjective preference and objective information entropy with the strict least square method as a tool is provided in the process of mcdm . with the development of worldwide shipping market , all kinds of special ship types and corresponding ship form evaluate alternatives are emerging . the traditional ( gb11697 - 89 ) method is only suitable for common ship types and it is not suitable for ocean floating structure system evaluation either 传统的国标法( gb11697一89 )只能对散货船、集装箱船、干货和杂货船、多用途船、油船和滚装船等普通船型进行方案评价，也不能用于海洋工程中浮式结构物的系统论证，故采用gb11697一89针对上述特殊船型进行船型方案论证和技术经济指标评价显然已不能满足实际工作需求和未来船型发展方向。
( 3 ) through theoretic analyzing and with aid of practical design results , the author have researched for the first time inland the relationship between design speed of hspgs line and its economical indexes such as the traffic demand , engineering cost , operating expense , the cost for train - set purchasing and operating revenue ( 3 )在国内首次系统地通过理论研究和总结实际定线资料，研究了高速铁路速度目标值与其客运需求、工程投资、机车车辆购置费、运营支出等技术经济指标的量化关系。
