摘要: : In an article on the role of temporal information in life-cycle assessment this journal, Field and colleagues argued that frequently it is not single product but “fleet” (or cohort) products “is appropriate unit analysis,” focusing fleet one “explicitly introduces notion time as a critical element comparative assessments. …” Major transitions, such replacement by alternative fleet, correspond to system transient rather than steady state, explicit consideration central analysis. One tool increasingly used part assessment, economic input-output (EIO) analysis, at best deals with implicit fashion. This illustrates how sequential interindustry model (SIM), formulation EIOmodel explicitly represents time, might be utilized assessment. SIM component accounting for required production activities resulting sequencing inputs. can thought engineering information. The data demands are likely met present or any near future. Even so, simulation methods use so-called synthetic have history productive number fields, including social sciences. SIM also utilizes contribution Joshi application EIO environmental impact inclusion well phases analysis. possibility discounting future events, its decision making, briefly discussed.
