The architecture that product lifecycle evaluates reachs the compositive concern that its green creates

Summing up lifecycle of current domestic and international product to evaluate the foundation that studies the current situation to go up, the architecture; that built product lifecycle to evaluate is making medium fundamental application undertake analytic foundation go up in green to LCA, established a kind of when make with green compositive relationship. Introductive product lifecycle is evaluated (Life-cycleAssessment, the resource that LCA) is a kind of complete to the product lifecycle is used up and environmental influence undertakes the environment of the evaluation manages a tool, also call product lifecycle to analyse (Life-cycleA Nalysis, state of environment of LCA) , resources is analysed (Resource And EnvironmentalPro-fileA Nalysis, r EPA) . The research that makes domestic and internationally integratedly, can LCA understand for: ?

Published a series of paper, established pattern of data of SPOLD detailed list. World each country also regards a kind of main environmental government tool as LCA in succession, and develop extensive research and applied practice. The TC-207 technology committee of ISO of international Organization for Standardization manages in IS014000 series environment obligate is evaluated for lifecycle in the standard 10 levels number (14040-14049) , already announced the standard such as analysis of detailed list of lifecycle of IS014040- principle and frame, IS014041- at present, reached executive measure to undertake standardizing the job to frame of the concept of LCA, technology, drove the development of LCA and application further. At present LCA is like Procter&Gamble in large company, AT&T, 3M received abecedarian application. Although the research of LCA and application work to obtain very great progress in recent years, but still immature, return existence to evaluate cycle long, cost is advanced defect. Have some of academic method, if evaluate and assure of data quality, the environment affects assessment technique to wait to still remain to study further and be perfected. At present our country still is in to the research of LCA start level, still complete the research report of LCA without the enterprise up to now, overall level still is in theory study and exploration phase. The article is summing up the foundation that studies the current situation domestic and internationally currently to go up, the architecture that evaluates to product lifecycle and the compositive concern that its and green create undertook discussing. The architecture that the architecture product lifecycle that product lifecycle evaluates evaluates is shown 1 times like the graph. Can you see from inside the graph the architecture of LCA comprises: by 3 parts? С of Tuo of island of Qiu of Dan of a surname of ⒛ of Peng of border sprain Gong occasionally border vinegar?1.

Does the technical frame lieutenant general that the technical frame that product lifecycle evaluates evaluates in product lifecycle evaluate process cent to be 4 phase: ? Head of Qian of collate Pi ㄒ paragraph Ы Duo?Goal Definition And Scoping) , detailed list is analysed (Life-cycle Inventory, LCI) , environment affects an evaluation (Impact Assessment) , explanation explains (Interpretation) . Product lifecycle is evaluated is these 4 phase the process of ceaseless iteration and improvement. Definition of Nextpage (1) target and limits limit target definition and limits is the one step with very crucial LCA, affect the content that follow-up phase works and method directly, and the effectiveness that evaluates a result. Target definition should have the purpose of LCA, reason and applied boy or girl friend clearly. The content such as the type that requirement of quality of condition of requirement of type of influence of degree of border of system of unit of the function that must make clear product system when limits is limitted, function, product, configuration, environment, data, hypothesis, limitation condition, primitive data, result examines type and evaluation report and form. LCA itself is an iteration process, when allowing to be analysed in detailed list and affect an evaluation, mix to the target / or limits undertakes necessary modification is mixed perfect. (Analysis of detailed list of analysis of 2) detailed list is whole to product system lifecycle the input of each phase or process and output undertake data is collected, quantify, the analysis is paratactic the course that gives detailed list to analyse a watch. The input includes input of energy input, raw material input, auxiliary material input, other physics to wait, output is the trash that points to air, water, soil to wait is discharged. Because inchoate LCA basically devotes oneself to product system energy, raw material to use up the ration that discharges with trash,analyse, because analysis of this detailed list is the most mature in 4 phase. (3) affects an evaluation to affect an evaluation is to apply ration and / or the process that qualitative method analyses the environmental effect with potential outcome to undertake evaluate and be descriptived to detailed list. ISO evaluates the effect process cent to be changed to affect classification, character, the computation that increase advantageous position 3 measure. The influence is classified (Classification) environment influence can divide those who be blame biology resource to use, biology resource is used, of land use, noxiousness of influence of noxiousness of calefacient, ozone loss, zoology, human body affects the whole world, of actinic oxidant form, acid rain, . The data that influence classification asks to analyse detailed list affects category correspondence to rise with the environment. If detailed list analyses the CO in the result, OK and corresponding whole world is calefacient. Character is changed (the environmental influence rate that Characterization) character changes every output that asks pair of detailed list are medium undertakes quantifying. Can use equivalent method commonly, for example, calefacient influence can introduce the whole world of some kind of material " the whole world is calefacient go situation (GWP) " undertake quantifying. GWP uses CO2 to make equivalent, the GWP that sets unit CO2 is 1. The computation that increase advantageous position (Weighting) is in necessary fall with significant circumstance, can change a result to undertake adding counterpoising computational to character, beg give a total influence value. (Specification of explanation of 4) explanation specification is analysed to detailed list and / or the consistency of impact assessment result and define goal and limits has analysis and opinion, so that be opposite,LCA result makes an explanation and put forward to improve an opinion to the product. 2.

The system of content of content system product that product lifecycle evaluates is a few crucial questions in be being evaluated according to product lifecycle and those who put forward, include product system, resource to shed analysis, environment to affect method of examine and verify of result of quality of analysis, data, evaluation and method of other and relevant theory. (1) product system basically studies of product system form basically and the characteristic of all sorts of product systems, its are specific research content includes product complete lifecycle (the process is unit) , the composition of the product (the function is unit) and the other activity related to the product. (The resources of complete lifecycle of product of analysis of 2) endowment headstream flows an analysis to include energy to shed analysis, stock to shed emission of analysis, environment to circulate an analysis. Because the product is complete sort of the resource in lifecycle is various, wear out condition is complex, the form of environmental emission is diversiform, because this is right,the energy in product system flows, stock shedding and analysis of travel of environmental emission inpour are very complex task. (The diversity of environmental influence form that resource of analysis of 3) environment influence is used up and environmental emission causes, degree is differ, the environmental effect that how causes effectively to place undertakes differentiating, classify and quantifying an analysis is a very complex issue, still be product lifecycle evaluates medium research heat at present. The environment affects research content of the analysis, the affirmatory, detailed account that includes an environment to affect index analyses what affect to the environment as a result to change and environmental influence quantity changes assessment technique to wait. (How does 4) data quality make sure the effectiveness of LCA result is the difficult problem of LCA all the time, its basically depend on get valid data hard and having analysis and opinion to its quality so formerly. Data quality is the uncertainty that points to data, but repeatability, consistency, accuracy and integrality. The target that its study, the data quality that includes detailed list analysis and the data quality that the environment affects. The data quality that detailed list analyses, the data quality of emission of the data quality that includes energy input again, data quality that stock inputs, environment. The environment affects data quality, include zoology environment to affect quality of data quality, data of human body noxiousness and quality of resource exhaust data. (5) is other and relevant academic Nextpage 3.

The technology propping up that the lifecycle of product of the technology that prop up that product lifecycle evaluates assesses basically includes database and knowledge base technology and software tool. (1) database and lifecycle of product of knowledge base technology are evaluated involve much data and knowledge, because the database related this need and knowledge base serve as,prop up. These database knowledge bases include character of environment of raw material resources environment of resources of knowledge base of database of character of environment of resources of database knowledge base, workmanship, carriage process is characteristic database knowledge base, use and defend process resource environmental character database knowledge base, reclaim database knowledge base, litter handles character of process resources environment knowledge base of database of character of process resources environment, . (2) evaluates lifecycle of software tool product to evaluate a process to have data bulk big, information content computational workload is big, big wait for a characteristic, because this needs have the aid of,at the computer powerful data and information processing ability shorten evaluation cycle and active to evaluating information to undertake management. The assessment that a few LCA had appeared on international at present tool, if Holand Pre seeks advice from the SimaPro4 of the orgnaization.

Product lifecycle evaluates the compositive relation green that makes with green to make is the contemporary production mode that influence of environment of an integrated consideration and resource use up, its target is to make product from the design, make, pack, carry, use discard as useless in the whole lifecycle of processing, negative to the environment effect is dinky, resource utilization rate is extremely high, make business economic benefits and social benefit harmonious change. Can see from the definition, the resource that the executive need that green creates faces product complete lifecycle to consider a product is used up and the environment pollutes a problem. Because this can use LCA technology,in the advantage of this respect the resource of complete to the product lifecycle is used up reach its potential environment effect to undertake differentiating, quantify and evaluate, assist what green makes to carry out. Product lifecycle evaluates in green the application in making can undertake understanding from the following respects: (The detailed list analysis that lifecycle evaluates 1) can be what green makes carry out offer product complete lifecycle the detailed content in each unit processes flows, the data of energy shedding, trash shedding and information. (2) evaluates OK identifying through lifecycle the important level that resource of product complete lifecycle is used up and the environment affects, facilitate crucial contradiction is captured in the executive process that makes in green, specific aim ground undertakes improve and be optimizinged to making a system. (3) is the same as LCA CAD/CAM/CAPP to wait to already products plan and workmanship design technology undertake compositive, subdesign is decision-making. (4) is made in green undertake decision-making when, does need consider: of 5 big decision-making targets? Go straight towards C of Q of Zuo , quality, cost, environment to affect E, resource to use up R. Lifecycle evaluates the environment in can assisting pair of production systems to affect E, resource to use up R the analysis of target of two big features, evaluation and decision-making.

The compositive relation that product complete lifecycle is based on between technology of each special subject and LCA can use a figure 2 will describe. The article was summing up conclusion on the studies the current situation domestic and internationally foundation that current product lifecycle evaluates, built the architecture of LCA. The architecture of LCA incorporates the system of technical frame, content, technology that prop up 3 content, among them each content includes a certain number of specific content again. It is finally on the foundation that lifecycle evaluates pair of products to make medium application undertake an analysis in green, built LCA and green to make special subject technology be based on the compositive relation of product complete lifecycle.
