The fashion industry consists of textile industries that produce and sell textile raw materials clothing industries that manufacture and sell clothing distribution industries that sell fashion consumer goods fashion information fashion publishing and fashion consulting. As the fashion industry gradually moves from offline to online transactions at online shopping malls in the fashion county rose 3.3 percent year-on-year to 49.8158 trillion won in 2022, according to the Seoul Investment Administration. In other words through the pandemic due to COVID-19, the restructuring of fashion distribution channels has accelerated reducing offline distribution networks and rapidly growing online distribution networks. ssfshop, LF, Kolon FnC, and E-Land Group are strengthening their online distribution networks and marketing while Musinsa, W Concept, Zigzag, Able and Brandy which are called the online fashion platform “Big 5,” have “stormous growth.” In this way with the acceleration of online distribution in the fashion industry logistics centers are also establishing an online-only system. However unlike B2B fashion logistics B2C fashion logistics is not easy to achieve logistics operation optimization through automated facilities (Auto Sorter, Digital Picking System (DPS). The reason for this is that B2C fashion logistics manually performs a series of processes such as single/multiple picking of individual units invoice output packaging invoice attachment and delivery preparation according to individual orders of consumers. In addition B2C Fashion Logistics requires work speed and efficiency for rapid and accurate order processing coping with seasonal shipping demand packaging accuracy of skilled personnel and rapid return processing. A study on the efficient working method of B2C fashion logistics was published in 2022 through a study on how to streamline the B2C process of shoe logistics applying the Line Balance methodology. However there was a limit to the fact that the previous paper was not able to conduct comparative analysis with various companies by research and analysis centered on Company A. Therefore this study aims to expand line balancing research in 2022 to introduce the “Flow Shop and Job Shop Method,” which is a work process method and to compare and study work efficiency by applying the Flow Shop and Job Shop methods, focusing on the B2C tasks of Fashion Logistics Center A and B. In addition, this study differs from the meaning of mutual comparison and research on ways to increase work productivity by applying the Flow Shop and Job Shop methods of logistics centers to revitalize online channels in the fashion industry, focusing on the cases of Company A and B.
