The thousands of pieces of data included schedules of work supervisors, the dimensions of areas of land crossed during work, indicators extracted from enterprise resource planning (ERP) software applications, as well as qualitative information.<\/p>\n<p>Next, she conducted trials with the following three methods so as to design an effective forecasting model for estimating work project durations:<\/p>\n<ul>\n<li>Multiple regression<\/li>\n<li>Support vector machine (SVM)<\/li>\n<li>Neural networks<\/li>\n<\/ul>\n<p>The best models derived from each method were then tested on new samples for the purpose of assessing their actual performance, which proved to be virtually equivalent in each case.<\/p>\n<blockquote><p>This collaboration with IVADO and Mitacs led to development of a forecasting tool that will help improve our planning processes. Over the longer term, this more accurate estimation of gas grid buildout times should drive greater efficiency across the entire process and eventually lead to lower construction costs.\u201d<\/p><\/blockquote>\n<p>\u00c9ric Hurtubise, Contract Administration Advisor, \u00c9nergir<\/p>\n<p>Lastly, so-called determinist and robust models, each of which had limitations and advantages, were used to perform planning of 19 work sites chosen in the analysis, based on the forecast durations. The robust model turned out to be more representative of real-world conditions, and therefore is likely to enable better management of time-delay risk, which can then be used to optimize upstream allocation of projects among the various teams supervising the work.<\/p>\n<div class=\"six columns\"><div class=\"gdlr-item gdlr-column-shortcode\"><p style=\"text-align: center;\"><a href=\"https:\/\/www.hec.ca\/\" target=\"_blank\" rel=\"noopener noreferrer\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-14499\" src=\"https:\/\/vieux.ivado.ca\/wp-content\/uploads\/2018\/07\/Signature_carree_Web_HEC_Montreal_541.jpg\" alt=\"\" width=\"164\" height=\"122\" \/><\/a><\/p>\n<\/div><\/div>\n<div class=\"six columns\"><div class=\"gdlr-item gdlr-column-shortcode\"><p><a href=\"https:\/\/www.mitacs.ca\/\" target=\"_blank\" rel=\"noopener noreferrer\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-14065 size-small-grid-size\" src=\"https:\/\/vieux.ivado.ca\/wp-content\/uploads\/2016\/01\/MITACS.png\" alt=\"\" width=\"400\" height=\"121\" \/><\/a><\/p>\n<\/div><\/div>\n<div class=\"six columns\"><div class=\"gdlr-item gdlr-column-shortcode\"><p style=\"text-align: center;\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-14060 aligncenter\" src=\"https:\/\/vieux.ivado.ca\/wp-content\/uploads\/2019\/12\/eric-hurtubise.jpg\" alt=\"\" width=\"183\" height=\"122\" \/>\u00c9ric Hurtubise<br \/>\nContract Administration Advisor, \u00c9nergir<\/p>\n<\/div><\/div>\n<div class=\"six columns\"><div class=\"gdlr-item gdlr-column-shortcode\"><p><a href=\"https:\/\/www.energir.com\/\" target=\"_blank\" rel=\"noopener noreferrer\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-14067\" src=\"https:\/\/vieux.ivado.ca\/wp-content\/uploads\/2018\/08\/Energir_500x300.png\" alt=\"\" width=\"465\" height=\"122\" \/><\/a><\/p>\n<\/div><\/div>\n","protected":false},"excerpt":{"rendered":"<p>Margaux Flipo<br \/>\nHEC Montr\u00e9al<\/p>\n<p>\u00c9ric Hurtubise<br \/>\nContract Administration Advisor, \u00c9nergir<\/p>\n","protected":false},"featured_media":17178,"template":"","categories":[217],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v22.7 -
