Abstract.
Therefore, three main influence factors of following four aspects are chosen as evaluation factors: 1) Processing quality aspect: dimensional precision, form and positional precision, surface quality. 2) economy aspect: processing cost., cutting time, technical contents. 3) Resources and energy sources aspect: energy duty factor, equipments duty factor, material duty factor. 4) Environmental protection aspect: the noise pollution, the wastes pollution, the oil fog pollution.

Abstract.
With the harder marketing competition, increasing raw material price, higher requirement for energy saving and lower energy consumption, transformer designer is facing problems of how to choose parameters to meet both technical requirement and to reduce cost and loss.
Constraints include self, performance, material and process constraints.

Abstract.
The bracing length was only half of the excavation width responding to the restraining action from upright piles over there. 8-node reduced-integration elements were applied in both of the soil and support structure materials, with the total elements and total nodes were 4812 and 15126 respectively.
