To analyze the issues about order-picking efficiency currently being studied by relevant scholars in e-commerce warehouses, this paper reviews the literature on the application of order-picking strategy and efficiency optimization direction from 2020 to 2022. That mainly falls into two categories of picking systems: \u201cpicker-to-parts\u201d and \u201cparts-to-picker\u201d. In the \u201cpicker-to-parts\u201d picking system, more attention is paid to the picking strategies of storage assignment and order batching and the integration of multiple picking strategies. In contrast, in the \u201cparts-to-picker\u201d picking system, the main attention is on the man-machine cooperation in the Mobile Robot Fulfillment System (RMFS) and the Automated Storage and Retrieval System (AS\/RS), as well as the coordination of the picking station. Further, this paper proposes future research directions for two categories of picking systems: further studying the order splitting strategy and order delivery issues; considering the dynamic uncertainties; combining the automated picking system with different picking strategies, and so on.<\/jats:p>","DOI":"10.3390\/jtaer17040091","type":"journal-article","created":{"date-parts":[[2022,12,7]],"date-time":"2022-12-07T06:22:18Z","timestamp":1670394138000},"page":"1812-1830","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":27,"title":["Order-Picking Efficiency in E-Commerce Warehouses: A Literature Review"],"prefix":"10.3390","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3410-3273","authenticated-orcid":false,"given":"Yi","family":"Li","sequence":"first","affiliation":[{"name":"Network Social Development Research Center, Chongqing University of Posts and Telecommunications, Chongqing 400065, China"},{"name":"School of Economics and Management, Chongqing University of Posts and Telecommunications, Chongqing 400065, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ruining","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Modern Posts, Chongqing University of Posts and Telecommunications, Chongqing 400065, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dandan","family":"Jiang","sequence":"additional","affiliation":[{"name":"School of Economics and Management, West Anhui University, Lu\u2019an City 237012, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,12,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1016\/j.ejor.2006.02.025","article-title":"Research on Warehouse Operation: A Comprehensive Review","volume":"177","author":"Gu","year":"2007","journal-title":"Eur.
