Based On The Evaluation Method Of Fuzzy Gray Theory Appliance Product Life Cycle Green

Since the 90's of last century, the global economy obtained fast development; especially the economic development of our country has made the remarkable achievements, but along with the environmental pollution problems in recent years. How to administer the environment and how to protect the environment problems aroused people's great attention. Since the 21st century, countries are in change of industrial and agricultural production development strategy, to the resource utilization rationalization, the waste generated fewer quantizations, free from pollution to the environment or less polluted the direction of development, then in the global open a wave "green wave and low-carbon economy". In "green consumption", the green design and manufacturing of household electrical appliances arises, and becomes one of the current research hotspots. Evaluate a household electrical appliances is good or bad, besides traditional sense practicability, its greenness character must be considered. The greenness character of product quality is a fuzzy concept and the traditional method is difficult to evaluate it correctly. The greenness character of household electrical appliances is evaluated by Fuzzy-Gray theory in this topic. The main research contents listed below:The first chapter introduction, expounded the topic source, research situation and mainly research contents, pointed out the direction of subsequent research.The second chapter the Fuzzy-Gray theory, studied relevant Fuzzy-Gray theory method and laid a theoretical foundation of the subject study.The third chapter the construction of greenness character evaluation method of household electrical appliances, starting from the product life cycle study and construct the greenness character evaluation method of household electrical appliances based on Fuzzy-Gray theory.The fourth chapter the design of greenness character evaluation software of household electrical appliances, VB software was used to design"greenness character evaluation software of household electrical appliances"by the greenness character evaluation method of household electrical appliances based on Fuzzy-Gray theory.The fifth chapter experimental study, in order to validate the feasibility and practicability of the evaluation software, Through the experimental study on compiling software and evaluation method, related parameters are optimized, the optimized evaluation software more joint reality.The sixth chapter summarizes and prospect, reviewed the achievements and innovation points and expounded the problems existing in the research and the possible ways to solve.Major innovations:1. Through the research situation of study, put forward and constructed the"greenness character evaluation method of household electrical appliances based on Fuzzy-Gray theory"model.2. VB software was used to design"greenness character evaluation software of household electrical appliances"by the greenness character evaluation method of household electrical appliances based on Fuzzy-Gray theory.3. Through the experimental study on compiling software and evaluation method, related parameters are optimized, the optimized evaluation software more joint reality.
