Global manufacturing industry continues to respond to the changes in development environment through digital transformation to establish, maintain, and increase competitiveness. At the same time, with the process of digital transformation, it will gradually realize smart manufacturing, Industry 4.0, and innovative business models. In recent years, many international R&D institutions and manufacturers continuous to integrate sensing, Internet of Things, artificial intelligence, cloud platforms and edge computing as well as information communications and smart technologies into machinery and production systems to form smart machinery products and applications to assist the manufacturing industry to accelerate its digital transformation. This research analyzes the cases of Global Lighthouse Network for Industry 4.0 to understand the needs of digital application solutions and also observes current developments of smart machinery products in the world. Finally, it explains the potential benefits and international cases of using smart machinery to realize the business model of Equipment as a Service (EaaS), which triggers the strategic thinking of using smart machinery to strive for business opportunities of digital transformation in the manufacturing industry.
