Based on the theory of multiple attribute decision making, an algorithm of comprehensive and comparative evaluation for product environmental adaptability is presented. A program is built and used in an example of design improvement. The result shows that the proposed method and algorithm are practical and effective to the development of green products.展开更多

In recent years, public rental houses appeared as a new type of affordable houses. The national government took the construction of public rental houses to the national strategic level. Currently, there are many problems in the public rental house construction. For example, policy mechanisms are inadequate, the use of funding is not in an efficient way, the location of public rental houses is far away from the downtown, the plot ratio is too high, and facilities are incomplete. There are no appropriate indicators to comprehensively evaluate the public rental house construction. Based on the livable evaluation system in Chongqing, we selected four aspects of relevant indicators as the economic suitability, environmental suitability, social suitability, and life suitability to establish the public rental house construction suitability evaluation system.展开更多
