Much research has been done on construction safety cost. However it is always on a qualitative level, little quantitative research has been done, especially on the safety cost of water conservancy construction project. In this paper, by the combined use of grey correlation model and optimal safety cost model which is under dialectical understanding, a dynamic management model on the safety cost of...
Transmission and transformation is an important part of National Electric Power building, with the scope of this paper, the life cycle management assessment was considered as a multi criteria decision problem. A model aiming the usage of analytic network process (ANP) in the program selection is developed owning to the evaluation of the relations between the transmission and transformation project...
