To get the global optimal process plan,a synthesizing optimization approach for machining scheme selection and operations sequencing based on genetic algorithm(GA) was proposed.

Comparasion and selection of process scheme is one of most important stages in the construct of urban wastewater treatment plant, which decides investment cost, running cost, effluent quality, operation supervision and so on.

Application of the intelligent decision support system (IDSS) to scheme selection of air-conditioning cold/heat source;

Based on construction scheme selection and construction experiences of large steel structure engineering in Qingdao,such as extension of Qingdao Liuting Airport,Qingdao International Convention Center and Qingdao Swimming and Diving Natatorium,construction schemes such sliding method,lifting pillar method and assembling at high altitude method are analyzed and compared.

This article makes an introduction mainly on the process of the scheme selection for the Jinlaidao-Outer Ring Road interchange and gives a description to the general design thought of the interchange scheme.

Control Project Selection of Permanent Magnet Synchronous Servo System;

Plan selection of straws gasification project and its environmental impact - A case study from Yishui Village, Xinzheng City, Henan Province.;

The comprehensive judgement method in fuzzy mathematics was applied to resolve the problem of project plan selection.

Using AHP,the paper analyzes the plan selection of joint transport of military materials from the perspectives of speed of delivery,cost of transportation,labor productivity,fuel comsumption and total investment,determines their respective decision weights and finally presents a cast study.
