The safety evaluation index of subway station operation is established from the passengers, equipments and facilities ability, emergency ability and other aspects. Specific to the limitation the traditional entropy weighting method, the improved vertical and horizontal weighting method is puts forward, and safety evaluation method of the subway station operation based on grey clustering method is proposed. Finally, taking the Beijing subway stations in China as an example, the rationality and reliability of this method is verified.

Visual Basic 6.0

The research which aimed at low integration and inefficiency of the management in the existing tool management of the machinery manufacturing enterprise (group) in our country, developed tool whole life cycle management system software. It based on the tool whole life cycle theory and adopted Microsoft Visual Basic 6.0 language and Access2003 database. The system could do a series of operation, such as, tool purchasing application, tool adding, tool modifying, tool inquiry, tool borrowing and return, tool breakage forecast. And it could make assembling and disassembling tool sheets according to techniques plan. The system could use network database to store the data and output the data by the form of sheet. And it achieved tool information inquiry, distribution and integrated management.

Along with the arrival of Chinese hydropower construction investment peak and the application of computer technology in the whole life cycle of hydropower station of every stage, isolated data appeared between different stages in the whole life cycle, as well as different professional module of the same stages. Based on the whole life cycle theory of hydropower station, overall planning informatization of basin wide hydropower development company was studied. The overall planning includes main information system modules of each stage of the whole life cycle of hydropower station, such as: basin wide or river planning stage, pre-feasibility study stage, feasibility study stage, bidding and construction stage, completion operating and maintenance stage and digitalization basin stage. Meanwhile, based on the transverse business sectors, management of comprehensive enterprise, hydropower station construction process, production operations, and function business modules of hydropower station was studied. After the implementation of the plan, whole process planning informatization is except to be unified, and a unified data model should be established. Finally, a new management model can be formed, the purpose of efficient management can be achieved.

Developing Low-carbon building is the essential measure for our society transfers to low carbon economic society. Therefore, we need chose appropriate policy evaluation tool that can help authorities to make suitable construction policy. The carbon emission in whole life cycle theory is a efficient tool to evaluate the value of Low-carbon building.
