引言
開始建造一套完整的新型水泥生產(chǎn)工藝設備或在已有的水泥生產(chǎn)設備上進行主要設備生產(chǎn)能力的擴充改造，這些計劃都應該在詳細的技術經(jīng)濟分析的基礎上實施。這樣的研究涉及到采用最好的技術方案、總的成本和總的運營支出這些方面，同時也涉及到生產(chǎn)、所需的勞動力及在一定時間段內(nèi)投資回收的運營規(guī)模，它能體現(xiàn)出工程較好的經(jīng)濟可行性。
Introduction
The decision to start the construction of an entirely new cement plant facility, or a major capacity extension at an existing cement works, should always be based on a detailed techno-economic feasibility study. Such a study will indicate to the promoter the viability of the business in terms of the best technical solution, the overall capital and operating casts, the magnitude of the operation in terms of production and workforce needed, and the return on his investment over a period of time.
