Current approaches rely substantially on human engagement, making them costly and unsustainable, especially in high-volume industrial complexes like fulfillment centers. The length of time that fulfillment center equipment failures last is particularly important because it affects operational costs dramatically. A machine learning approach for identifying long and short equipment failures is presented using historical equipment failure and fault data. Under a variety of hyperparameter configurations, we test and compare the outcomes of eight different machine learning classification algorithms, seven individual classifiers, and a stacked ensemble. The gradient boosting classifier (GBC) produces state-of-the-art results in this setting, with precision of 0.76, recall of 0.82, and false positive rate (FPR) of 0.002. This model has since been applied successfully to automate the detection of long- and short-term defects, which has improved equipment maintenance schedules and personnel allocation towards fulfillment operations. Since its launch, this system has contributed to saving over $500 million in fulfillment expenses. It has also resulted in a better understanding of the flaws that cause long-term failures, which is now being used to build more sophisticated failure prediction and risk-mitigation systems for fulfillment equipment.<\/jats:p>","DOI":"10.1155\/2023\/8557487","type":"journal-article","created":{"date-parts":[[2023,4,16]],"date-time":"2023-04-16T01:50:07Z","timestamp":1681609807000},"page":"1-10","source":"Crossref","is-referenced-by-count":0,"title":["The Discriminants of Long and Short Duration Failures in Fulfillment Sortation Equipment: A Machine Learning Approach"],"prefix":"10.1155","volume":"2023","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6909-5616","authenticated-orcid":true,"given":"Abed","family":"Mutemi","sequence":"first","affiliation":[{"name":"NOVA Information Management School (NOVA IMS), Universidade Nova de Lisboa, Campus de Campolide, Lisboa 1070-312, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0834-0275","authenticated-orcid":true,"given":"Fernando","family":"Bacao","sequence":"additional","affiliation":[{"name":"NOVA Information Management School (NOVA IMS), Universidade Nova de Lisboa, Campus de Campolide, Lisboa 1070-312, Portugal"}]}],"member":"311","reference":[{"article-title":"Mapping Amazon Warehouses: How Much Square Footage Does Amazon Own?","year":"2022","author":"BigRentz","key":"1"},{"author":"D.
