This paper aims to investigate the complex q\u2010rung orthopair fuzzy (CQROF) planar graphs (CQROFPGs). In a CQROFPG, the nodes and edges are based on complex QROF information that represents the uncertain knowledge in the range of unit circles in terms of complex numbers. The motivation in discussing such a topic is the wide flexibility of QROF information in the expression of uncertain knowledge compared to intuitionistic and Pythagorean fuzzy settings. We discussed the complex QROF graphs (CQROFGs), complex QROF multigraphs (CQROFMGs), and related terms followed by examples. Furthermore, the notion of strength and planarity index (PI) of the CQROFPGs is defined and exemplified followed by a study of strong and weak edges. We further defined the notion of complex QROF face (CQROFF) and complex QROF dual graph (CQROFDG) and exemplified these concepts. A study of isomorphism, coweak and weak isomorphism, is set up, and some results relating to the CQROFPG and isomorphisms are explored using examples. Furthermore, the problem of short circuits that results due to crossing is discussed because of the proposed study where an algorithm based on complex QROF (CQROF) information is presented for reducing the crossing in networks. Some advantages of the projected study over the previous study are observed, and some future study is predicted.<\/jats:p>","DOI":"10.1155\/2021\/8295997","type":"journal-article","created":{"date-parts":[[2021,7,22]],"date-time":"2021-07-22T17:05:05Z","timestamp":1626973505000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Investigating the Short\u2010Circuit Problem Using the Planarity Index of Complex q\u2010Rung Orthopair Fuzzy Planar Graphs"],"prefix":"10.1155","volume":"2021","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2289-7464","authenticated-orcid":false,"given":"Abrar","family":"Hussain","sequence":"first","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1702-8643","authenticated-orcid":false,"given":"Ahmed","family":"Alsanad","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1438-6413","authenticated-orcid":false,"given":"Kifayat","family":"Ullah","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5878-714X","authenticated-orcid":false,"given":"Zeeshan","family":"Ali","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5715-9299","authenticated-orcid":false,"given":"Muhammad Kamran","family":"Jamil","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5094-5561","authenticated-orcid":false,"given":"Mogeeb A.
