VALUE JUDGMENT INTEGRATION MODEL FOR ALLOCATION IN LCA

摘要

When handling, multivariate impacts analysis, i.e. in acknowledging multiple incommensurable dimensions, any decision making process requires a step of value judgement declaration. Here is presented an extension of allocation systems based on Majeau-Bettez formalism in order to integrate multi-criteria allocation. The use of a hierarchy process on allocation keys enable to treat multi-functionality according to decision makers preferences. The global production balance is verified whatever incompleteness in values or attributes characterisations. This enable the allocation between valued co-products of distinct attributes. The process of elicitation and implementation of values in LCA will reflect our cultural portrait. Our perspective is to develop this model to integrate all value judgements required in LCA. Thus we would provide a tool for a complete agent based LCA-modelling.
