The debate on global warming, for example, could affect the use of coal in some areas; recycling lessens the amount of new material required; and the increasing use of non-mineral materials, such as plastics, affects the intensity of use of metals and minerals per unit of GDP.Competition, declining mineral grades, higher treatment costs, privatization and restructuring are each putting pressure on mining companies to reduce their costs and increase their productivity.
The key issues to implement such a model updating are discussed such as sampling with design of experiments, selecting the significant updating parameters and constructing a quadratic polynomial response surface.
An accurate finite element model is a necessity for analyzing the bridge's health status.
The uniform design combined with response surface finite element model updating method is proposed in this paper.
The introduction of new techniques has allowed existing constraints to be successfully overcome.
This was achieved through sound engineering principles and optimization during the Field Development Plan.
