The vision of Industry 4.0 is an integrated ecosystem in supply chain where every item and human in the plant has an ID in production and works without any external intervention, communicating with each other in every operation. Although such a concept of manufacturing may sound futuristic to many companies, and especially SMEs, the transition to this future is inevitable, and organizations need a roadmap to clearly understand the concepts and effectively execute the applications of Industry 4.0. In this paper, the level of importance of each Industry 4.0 criterion for SMEs is expressed and used to develop a quantitative maturity model. Analytic Hierarchy Process was utilized to calculate the weights of dimensions and maturity items. An iterative procedure led to 9 different dimensions and 33 correlated items. Initial findings showed that the "Strategy and Organization" dimension has the highest impact on maturity level along with the items "Manufacturing Software", "Employees", and "Industry 4.0 Roadmap".
Nesnelerin İnterneti (IoT) alanında yapılan proje uygulamalarındaki artış yeni ihtiyaçların ortaya çıkmasına neden olmaktadır. Uzak mesafe, düşük güç tüketen ve batarya ile çalışan sensörler ile bu sensörleri destekleyen kablosuz iletişim protokolleri giderek daha popüler hale gelmektedir. Bu çalışmada literatürde LPWAN (Low Power Wide Area Network) olarak tanımlanan bu yeni teknolojinin özellikleri, IoT ağlarında kullanılan diğer teknolojilerden farkları ve LoRa (Long Range) sensörlerin güç optimizasyonu teknikleri literatür incelemesi ve örmek uygulama üzerinden irdelenmiştir.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
