摘要: Abstract Application of Linear Programming (LP) Modelling to Life Cycle Assessment (LCA) is a novel approach analysing and managing the environmental performance complete product system. Not only can it solve problem allocation burdens in Inventory stage LCA, but also enables optimum system be investigated. Once have been allocated amongst different products on basis marginal changes activities, they are aggregated quantify impacts then reduced single impact function which treated as new objective LP model. The solution gives identifies places where improvements made. If multiobjective applied, combined with other requirements, such societal preferences or economics, thus giving best compromise for perfomance. idea behind this illustrated by simplified analysis produce thermoplastics.
