The Internet of Things is a notion that emerged with the fourth industrial revolution as a result of the finding that things that were born of the Internet can connect without the need for external causes (IoT). The communication of items with one another ensures that firms will spend as little time and money as possible on labor. Businesses that want to make the switch to the Internet of Things are going to run across a lot of challenges. The process of identifying and fixing these issues may result in both time and financial waste. Within the scope of this research, we looked at the challenges that are associated with the IoT. As a consequence of the research, the level of relevance of the elements that are generating these challenges was figured out using multi-criteria decision-making (MCDM) procedures, and the findings were given to the businesses. We decided on the primary criteria, as well as the secondary criteria that are connected to these primary criteria. The communication of different objects with one another is the primary goal of businesses that are making the shift to Industry 4.0. The purpose of this research was to identify the factors that contributed to the challenges encountered throughout the evolution to Industry 4.0. In the next step of the MCDM process, the DEMATEL approach was used to evaluate the level of significance associated with each of the factors. As a result of the research, we were able to establish which factors should be regarded as important for businesses that are interested in making the shift to the IoT. In this approach, businesses will be able to speed up the transition while limiting the amount of time and money lost in the process. 2022 2022 22 29 10.54216/JISIoT.070202 https://www.americaspg.com/articleinfo/18/show/1484
