- Migration strategy toward innovative, digitalized, and harmonized production systemsPublication . Cala, Ambra; Cachada, Ana; Pires, Flávia; Barbosa, José; Wermann, Jeffrey; Colombo, Armando W.Industry today is facing the fourth Industrial Revolution, also called Industry 4.0, pulled by the market demand of shorter delivery time and product life cycles, with increased product variety and smaller lot sizes, and pushed by innovative technologies, such as Cloud computing, big-data analysis, connected Cyber-Physical Systems (CPSs), Internet of Things, and related services, as well as autonomous robots and augmented reality. Industry 4.0 is an industrial paradigm that is proposing to transform the traditional factories into smart factories, which are more competitive, efficient, and productive. The goal is the rapid introduction of new tangible products and intangible products (services) into the market as soon as market and customer requirements change. In order to achieve this goal, the production process itself should be more agile and particularly correctly digitalized.
- Petri nets methodology for the design and control of migration processes towards industry 4.0Publication . Cachada, Ana; Pires, Flávia; Barbosa, José; Leitão, Paulo; Cala, AmbraThe fourth industrial revolution, commonly known as Industry 4.0, germinated in Germany as an industrial program of the government to reinvigorate the manufacturing sector. Nowadays, this change in the industrial paradigm has reached a global scale and is proposing to transform the traditional factories into more competitive, efficient and productive industries. In order to accomplish this goal it is necessary to establish methodologies to migrate from the traditional systems to innovative systems, namely those applying the Cyber-Physical Production Systems (CPPS) concepts. This paper proposes a methodology based on the Petri nets formalism for the modelling, analysis, validation and simulation of the migration process during the design phase and the control and monitoring of such processes during the implementation phase.
