伊敏露天矿原煤计价方式临界点的确定

煤炭计价方式主要有按灰分计价和按发热量计价两种，在实际工作中发现某一批煤炭分别按两种计价的价格相差很大，并且有一个临界点，灰分大于该点的煤炭采用发热量计价时，其价格高于按灰分计价，反之则低于按灰分计价。对此我们通过数学上的线性相关理论，计算出该临界点，指导实际工作，提供一条提高经济效益的途径。

现阶段招投标遇到的困惑及其对策分析

 文章从现阶段招投标遇到的困惑谈起,指出了招投标过程中依然存在着一些问题：一是“围标”及“明招暗定”现象;二是技术标趋同,评标作用严重弱化,形成了“评标失灵”现象;三是“评标失灵”现象的存在影响了建筑业的健康发展。针对这些问题,文章提出了对策和建议：一是改变目前的现场报名方式,推行网上报名,真正实现随机、自主、公开、公平报名;二是加强专家评标的独立性,严格限制非评标人员利用现场服务的机会与评标人员接触;三是提出了“实力标”的概念,建议对技术标进行进一步地完善与扩充,从技术标上升为“实力标”,对标书的评判要能评出全貌、评出优势、评出企业水平,使评标环节真正发挥应用的作用。
