Traditional manual order picking is extremely susceptible to infection spread among workers and picking errors, while automated medical waste sorting systems can handle large volumes of medical waste efficiently and reliably. This paper investigates the optimization problem in the automated medical waste sorting system by considering the operational flow of medical waste. For this purpose, a mixed-integer programming model is developed to optimize the assignment among medical waste, presorting stations, and AGVs. An effective variable neighborhood search based on dynamic programming algorithm is proposed, and extensive numerical experiments are conducted. It is found that the proposed algorithm can efficiently solve the optimization problem, and the sensitivity analysis gives recommendations for the speed setting of the conveyor.<\/jats:p>","DOI":"10.1155\/2021\/4313749","type":"journal-article","created":{"date-parts":[[2021,6,15]],"date-time":"2021-06-15T19:20:09Z","timestamp":1623784809000},"page":"1-12","source":"Crossref","is-referenced-by-count":3,"title":["AGV Scheduling Optimization for Medical Waste Sorting System"],"prefix":"10.1155","volume":"2021","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2795-8361","authenticated-orcid":true,"given":"Xueting","family":"He","sequence":"first","affiliation":[{"name":"School of Management, Shanghai University, Shanghai, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3761-4017","authenticated-orcid":true,"given":"Hao","family":"Quan","sequence":"additional","affiliation":[{"name":"Shibei Hospital, Jing\u2019an District, Shanghai, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3483-1913","authenticated-orcid":true,"given":"Wanlong","family":"Lin","sequence":"additional","affiliation":[{"name":"Shanghai No. 3 Rehabilitation Hospital, 100 Jiaocheng Road, Jing\u2019an District, Shanghai 200072, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9868-3433","authenticated-orcid":true,"given":"Weiliang","family":"Deng","sequence":"additional","affiliation":[{"name":"School of Management, Shanghai University, Shanghai, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4426-4318","authenticated-orcid":true,"given":"Zheyi","family":"Tan","sequence":"additional","affiliation":[{"name":"School of Management, Shanghai University, Shanghai, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"issue":"4","key":"1","first-page":"S8","article-title":"Environmental and financial impact of a hospital recycling program","volume":"79","author":"L.
