Nowadays, Industry 4.0 will become urgent to be implemented in most of the developed countries although it is still mainly conceptually. As there are three different aspects consisting of Industry 4.0 (I 4.0) such as: digital systems; biological systems and physical systems, most of research published works was focused on mainly the first one. The smart manufacturing system (SMS) is not a new invention. It is a rebirth of new version of manufacturing systems as so called a hybrid system taken into consideration reconfiguring it through adding machines with sensors, actuators and control architectures for achieving Industry 4.0. There are many challenges when reconfiguring hybrid-manufacturing systems as a major concept of Industry 4.0 representing into: degree of individual system' complexity; reconfigurable machines; material handling systems, system layout, competitive manufacturing strategies (leanness and agility), and embedded systems (cyber physical systems). In this paper, a new perspective of reconfiguring hybrid-manufacturing system was illustrated taking into consideration the previous challenges and the re-configurability level toward Industry 4.0 was proposed.
