چکیده

In microsimulation models, the behaviours of agents as intelligent objects aremodeled through various behavioral modeling techniques, which give rise touncertainties in the modeling workflow and predicted outputs. ILUTE (IntegratedLand Use Transportation Environment model) is an agent-object-basedmicrosimulation model system, in which many agents (persons, families,households, firms, etc.) intelligently and/or randomly act and interact in acomplex ways. A 150,000 (150K) synthetic base year (1986) household sampleof the Greater Toronto and Hamilton Area (GTHA) population is used as thestarting point for undertaking twenty-years of historical simulations (1986-2006).In order to analyze the uncertainty associated with stochastic behaviours in theILUTE model system, a 1000 independent runs using different initial randomnumber seeds are generated and tested. In this paper, the behaviour of thedemographic updating module were tested by examining the variability of itsoutputs including births, deaths, families, and households across simulation runs.The test results show that all the simulated outputs’ distributions are generallynormally, or very close to normally, distributed. In general, ILUTE can simulatedemographic updating process with considerable reliability and confidence.

اطلاعات بیشتر در مورد COI

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
