It provides a foundational understanding of the distinction between uncertainty analysis and sensitivity analysis, specifically focusing on how input factor uncertainties influence model outputs. The content covers definitions of global sensitivity analysis, the importance of resolution levels, and the application of various sampling techniques for model structures, weighting methods, and aggregation rules in policy-related quantification.",{"@graph":69,"@context":122},[70,84,105],{"@type":71,"itemListElement":72},"BreadcrumbList",[73,77,79,82],{"item":74,"name":75,"@type":76,"position":8},"https://docshare.wps.com","Home","ListItem",{"item":78,"name":9,"@type":76,"position":14},"https://docshare.wps.com/document/",{"item":80,"name":40,"@type":76,"position":81},"https://docshare.wps.com/document/research-report/",3,{"item":83,"name":65,"@type":76,"position":19},"https://docshare.wps.com/document/sensitivity-analysis-practical-problems-in-quantification/292828/",{"url":83,"name":65,"@type":85,"image":86,"author":91,"headline":65,"publisher":94,"fileFormat":97,"inLanguage":63,"description":67,"dateModified":98,"datePublished":99,"encodingFormat":97,"isAccessibleForFree":100,"interactionStatistic":101},"DigitalDocument",{"url":87,"@type":88,"width":89,"height":90},"https://docshare.wps.com/thumbnails/sensitivity-analysis-practical-problems-in-quantification/292828.png","ImageObject",300,407,{"name":92,"@type":93},"Oliver Hayes","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-10-29","2026-09-17",true,{"@type":102,"interactionType":103,"userInteractionCount":29},"InteractionCounter",{"@type":104},"ViewAction",{"@type":106,"mainEntity":107},"FAQPage",[108,114,118],{"name":109,"@type":110,"acceptedAnswer":111},"What is the fundamental difference between uncertainty analysis and sensitivity analysis?","Question",{"text":112,"@type":113},"Uncertainty analysis focuses on quantifying the uncertainty in a model's output, whereas sensitivity analysis is the study of how the relative importance of different input factors affects that output.","Answer",{"name":115,"@type":110,"acceptedAnswer":116},"How does Andrea Saltelli define global sensitivity analysis?",{"text":117,"@type":113},"He defines it as the study of how the uncertainty in the output of a model can be apportioned to different sources of uncertainty in the model input.",{"name":119,"@type":110,"acceptedAnswer":120},"What components can be sampled in a model beyond just input factors?",{"text":121,"@type":113},"One can also sample modeling assumptions, such as the number of indicators included, the weighting methods applied, and the specific aggregation rules used.","https://schema.org",{"og:url":83,"og:type":124,"og:title":65,"og:site_name":95,"og:description":67},"article",{"robots":126,"canonical":83},"index,follow",{"doc_id":128,"site_id":62},292828,1791006827,{"code":4,"msg":5,"data":131},{"doc_id":128,"user_id":132,"nickname":92,"user_avatar":133,"doc_module":4,"category_id":39,"category_name":40,"doc_title":65,"doc_description":67,"doc_content":134,"file_id":135,"file_url":136,"file_type":137,"file_size":138,"view_count":29,"is_deleted":4,"is_public":8,"is_downloadable":8,"audit_status":8,"page_count":139,"language":140,"language_code":63,"site_id":62,"html_lang":63,"table_of_contents":141,"faqs":142,"seo_title":143,"seo_description":67,"update_tm":144,"read_time":145,"preview_page_count":4},687207020761,"https://ap-avatar.wpscdn.com/davatar_155a257f0dc6eb9ab79c44ca47cae57d","Sensitivity Analysis  \nAndrea Saltelli  \nCentre for the Study of the Sciences and the Humanities (SVT) -University of Bergen (UIB) Institut de Ciència i Tecnologia Ambientals (ICTA)  \n-Universitat Autonoma de Barcelona (UAB)  \nPhD-course  \nNumbers for policy: Practical problems in quantification  \nBergen, March 13-17, 2017  \nWhere to find this [talk: www.andreasaltelli.eu](talk: www.andreasaltelli.eu)  \n = more material on my web site  \n= discussion time  \nSensitivity analysis books available on LibGen   \nWhat is sensitivity  \nanalysis?
