Research On Key Technology Of Carbon Emission Mapping Oriented Customer Requirement

With the environmental problems such as global warming becoming increasingly serious and people’s environmental awareness gradually improved,the concept of green and low carbon has gradually became the main melody of enterprise and customer.Control carbon emissions,reduce environmental stress and achieve low-carbon and sustainable development is very important.Establish multi-hierarchy carbon emission mapping model oriented customer requirements and build carbon emissions analysis model in the product layer and function module layer is an important work in low carbon technology.This paper studied the acquisition methods of customer green requirements and built the customer green requirements acquisition template to analysis green requirements.A customer green requirements forecasting method based on customer characteristics was put forward and quantified the influence of customer characteristics by information gain.On the basis of acquired customer requirements,the fuzzy analytic hierarchy process method was employed to determine the importance of requirements and mapped the customer green requirements to the parameters of product function module unit based on improved QFDE.Established the customer green requirements and product function module unit parameter mapping model.A carbon emissions quantitative model was established based on life cycle analysis,it can analysis carbon emissions of the product layer comprehensively.Quantified and distributed the carbon emission to the product function module unit by using modularization method,it mapped the carbon emission of product layer to the carbon emissions of function module effectively.For critical carbon emission module unit,based on the sensitivity analysis method the mapping relationship between the key engineering parameters and carbon emissions change was studied.Bases on the mapping relationship between the requirements and the module unit parameters,identified the requirements that affect the carbon emission larger and feedback the requirements to customer.At the same time combined with the results of the carbon emissions in the product layer,function module layer and parameter layer,provided some guidance to product low carbon optimization.Finally,taking refrigerator product as an example,the implementation of the method is illustrated.
