“…These methods have been proved to be adequate in static production lines however, the necessity of I4.0 to maintain flexible productivity that emerges the continuous shop-floor transformations, does not allow traditional safety analysis to perform well since they are typically demand a large amount of performance data for an adequate operation. The necessity of on-the-fly predictive maintenance emerges the adoption of more flexible and holistic methods for hazard analysis defined from the design phase of complex systems in shop-floor environments such as STPA [37], RiskSOAP [23], Decision Making Grids and Jack Knife Diagrams [38] tools that endorse synchronous automated systems with the necessitated dependability [39], [40]; that will eventually allow predictive maintenance. Such methods integrated with artificial intelligence, big data and visual analytics constitute powerful tools that strengthen the prediction of hazard situations in production lines, preventing excessive down time, decreasing thus the excessive maintenance costs.…”

The so-called "fourth industrial revolution" or Industry 4.0 aims to transform the current EU industries into synchronous global market leaders, by incorporating into their production and functional framework the contemporary digital opportunities. Several EU countries have already launched the initiatives to adopt the next generation technologies into their industries. Recently, Greece recognized the necessity to upgrade its industrial environment with features such as "flexible production lines", "smart IoT solutions", "collaborative robotics", "inter-operable services", "adaptable industrial processes" etc., by identifying them as the key technological instruments that will bring its industry into the forefront of EU production sector. This will allow to state to overcome the so far major socio-economic and financial barriers that dragged the country back from its extrovert market potential. To this end, the paper at hand aims to propose a comprehensive transition to Industry 4.0 strategy by introducing a conceptual implementation approach that will pose the steps to be followed for the Greek stakeholders in order to pass from the era of computational automation, through the digital transformation, into the era of the ubiquitous cyber-physical systems (CPS), necessitated from the next generation industrial environments.

Professional robots should be endorsed with great autonomy capabilities when designed for release into the market. The need for autonomy is further reinforced when robots are meant to be used for crisis management situations, where close collaboration with humans and trustworthy operation in hazardous environments is necessary. To this end, this article quantifies the system's autonomy by measuring its dependability. This is achieved by defining a qualitative metric system regarding the different levels of dependability that autonomous systems should retain in order to operate in various crisis situations. It provides a detailed analysis of each level of dependability and proposes the minimum requirements that should be fulfilled in each level, thus realizing a ranking system that outlines the overall system's ability to operate autonomously. The proposed analysis is applied on a real robotic prototype developed for crisis situations and evaluates the system's autonomy capabilities by qualitative assessing the levels of dependability it retains.
