Ecolego is a simulation software tool that is used for creating dynamic models and performing deterministic and probabilistic simulations. It is also used for conducting risk assessments of complex dynamic systems evolving over time. Ecolego can be applied in a variety of areas, but is mainly used for risk assessment in radioecology,〔 () ECOLEGO - A toolbox for radio ecological risk assessment, Proceedings of the International Conference on the Protection from the Effects of Ionizing Radiation’’, IAEA-CN-109/80. Stockholm: International Atomic Energy Agency. 229 - 232. 〕 environmental physics and PBPK modeling.〔 () 2-FUN - A project concerning full-chain and uncertainty approaches for assessing health risks in future environmental scenarios. EU 6th framework program. 〕 To facilitate the use of Ecolego in the field of radiology, specialized databases and other add-ons have been developed. For example, all radionuclides and their decay products have been integrated in the software. ==History== Ecolego was co-founded by Swedish Radiation Safety Authority (SSM)〔 () ''Swedish Radiation Protection Authority''〕〔 () ''Further AMBER and Ecolego Inter-comparisons'' SKI Report 2004:05 SSI Report 2004:01 〕〔 (), ‘’AMBER and Ecolego Intercomparisons using Calculations from SR 97 SKI Report 2003:28’’, SSI report 2003:11 〕 , the authority in Sweden responsible for the regulation of radioactive waste management and disposal, and NRPA〔 () ''the Norwegian Radiation Protection Authority''〕 , the Norwegian Radiation Protection Authority. The software was initially developed as a complimentary user interface to create compartmental models in Simulink. Simulink had very powerful and fast solvers for ordinary differential equations, but lacked support for running probabilistic simulations and handling of parameter values. Also, Simulink is very detailed – every equation is modeled by graphically operator blocks– making modeling time consuming and prone to mistakes. By relying on Simulink for simulations, full attention could be given to the development of an advanced user interface. As more and more features where added to Ecolego, the need for an integrated simulation engine grew. With the release of Ecolego 4 in 2008, a set of state-of-the-art solvers was incorporated and thus removed the dependence of Simulink. Today, SSM uses Ecolego for the review of SKB's〔() ''the Swedish Nuclear Waste Management Company''〕 (the Swedish Nuclear Waste Management Company) license application for the siting and construction of a repository for the final disposal of spent nuclear fuel in Sweden. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Ecolego」の詳細全文を読む スポンサード リンク
