The industrial revolutions and their impact on production systems have increased productivity and quality in manufacturing over time. Lean methods have been the driver of the development of production systems from the 1990s to the rise of the fourth industrial revolution, or Industry 4.0. However, many different approaches and methodologies have been described, applied, and discussed for achieving improvements in production systems. As a result, organizations are often confused in regard to the order, the convenience, and the outcomes intended by the different improvement strategies and techniques. This paper provides a systematic sequence of process optimization steps that can be applied to any organization. A conceptual model was built based on the systematic sequence. In addition, a simulation model was built with the goal of representing and quantifying the sequential steps of the conceptual model. The results of the simulation model show a clear improvement in quality, performance, and economic indicators, with the first two steps in the optimization sequence providing critical initial information, while the third step served as a net contributor to a global production system improvement for demanding market scenarios. Finally, we analyzed the impacts of Industry 4.0 on production systems and developed a methodological sequence to design, select, implement, and control projects, even those that include Industry 4.0 technologies.

Today, we are experiencing what it is being labelled as the Fourth Industrial Revolution (Industry 4.0) in terms of automation and control systems of cyber - physical production environments. These systems not only allow access to many innovative features based on network connections, but they also provide access to the world of the Internet of Things (IoT).  It is in this context that IoT changes the ways to link new technologies in order to obtain more efficient, intelligent, flexible and adaptable production systems; thus becoming an interdependence of the product itself that the companies wish to commercialize. Cyber- Physical Production Systems (CPPS) have the advantages of granular communications, common electric bandwidth for all users regardless of data speeds, compatibility in connection with free or guided space communication links and with the major compatibility with intensity modulation. IEC 61499 is generally based on a generic architecture, with specific software requirements, development rules that allow for portability and device configuration.Keywords: IoT, configuration, communication, CPPS, Industry 4.0, smart.

Growing consumerism and population worldwide raises concerns about society’s sustainability aspirations. This has led to calls for concerted efforts to shift from the linear economy to a circular economy (CE), which are gaining momentum globally. CE approaches lead to a zero-waste scenario of economic growth and sustainable development. These approaches are based on semi-scientific and empirical concepts with technologies enabling 3Rs (reduce, reuse, recycle) and 6Rs (reuse, recycle, redesign, remanufacture, reduce, recover). Studies estimate that the transition to a CE would save the world in excess of a trillion dollars annually while creating new jobs, business opportunities and economic growth. The emerging industrial revolution will enhance the symbiotic pursuit of new technologies and CE to transform extant production systems and business models for sustainability. This article examines the trends, availability and readiness of fourth industrial revolution (4IR or industry 4.0) technologies (for example, Internet of Things [IoT], artificial intelligence [AI] and nanotechnology) to support and promote CE transitions within the higher education institutional context. Furthermore, it elucidates the role of universities as living laboratories for experimenting the utility of industry 4.0 technologies in driving the shift towards CE futures. The article concludes that universities should play a pivotal role in engendering CE transitions.

A platform for the engineering design, performance, and control of an adaptive wind turbine blade is presented. This environment includes a simulation model, integrative design tool, and control framework. The authors are currently developing a novel blade with an adaptive twist angle distribution (TAD). The TAD influences the aerodynamic loads and thus, system dynamics. The modeling platform facilitates the use of an integrative design tool that establishes the TAD in relation to wind speed. The outcome of this design enables the transformation of the TAD during operation. Still, a robust control method is required to realize the benefits of the adaptive TAD. Moreover, simulation of the TAD is computationally expensive. It also requires a unique approach for both partial and full-load operation. A framework is currently being developed to relate the TAD to the wind turbine and its components. Understanding the relationship between the TAD and the dynamic system is crucial in the establishment of real-time control. This capability is necessary to improve wind capture and reduce system loads. In the current state of development, the platform is capable of maximizing wind capture during partial-load operation. However, the control tasks related to Region 3 and load mitigation are more complex. Our framework will require high-fidelity modeling and reduced-order models that support real-time control. The paper outlines the components of this framework that is being developed. The proposed platform will facilitate expansion and the use of these required modeling techniques. A case study of a 20 kW system is presented based upon the partial-load operation. The study demonstrates how the platform is used to design and control the blade. A low-dimensional aerodynamic model characterizes the blade performance. This interacts with the simulation model to predict the power production. The design tool establishes actuator locations and stiffness properties required for the blade shape to achieve a range of TAD configurations. A supervisory control model is implemented and used to demonstrate how the simulation model blade performs in the case study.

For the development of modern complex production processes in Industry 4.0, it is appropriate to effectively use advanced mathematical models based on Petri nets. Due to their versatility in modeling discrete-event systems, Petri nets are an important support in creating new platforms for digitized production systems. The main aim of the proposed article is to design a new software tool for modeling and control of discrete-event and hybrid systems using Arduino and similar microcontrollers. To accomplish these tasks, a new tool called PN2ARDUINO based on Petri nets is proposed able to communicate with the microcontroller. Communication with the microcontroller is based on the modified Firmata protocol hence, the control algorithm can be implemented on all microcontrollers that support this type of protocol. The developed software tool was successfully verified in control of laboratory systems. In addition, it can be used for education and research purposes as it offers a graphical environment for designing control algorithms for hybrid and mainly discrete-event systems. The proposed software tool can improve education and practice in cyber-physical systems (Industry 4.0).

Purpose: The purpose of this paper is to analyze the conditions under which continuous improvement practices are developed and to determine what success factors and barriers affect the sustainability of these practices in order to establish strategies that reduce the risk of failure of improvement proposals in companies.Design/methodology/approach: The paper presents a rigorous review of the success factors and barriers in the implementation of continuous improvement models in companies and a multiple case study in which four successful companies located in Bogota, Colombia, were compared using Bessant's maturity model.Findings: The results suggest the existence of systematic improvement processes in the four companies analysed in favour of the improvement of business competitiveness. After a convergence exercise between the success factors identified in the literature and the routines of the evaluation model used to identify the maturity of the companies in terms of improvement, five strategic fronts were identified to achieve sustainable improvement proposals:(1)have management commit to the improvement and guarantee resources, (2) define a methodology to implement, (3) facilitate and systematize the information on the interventions, (4) design training programs and incentives to encourage employee involvement, and (5) generate a verification and control system to provide real-time feedback on the progress of the improvement actions.Research limitations/implications: This research paper was limited by the analysis of four large Colombian companies, which did not allow the generalizability of findings. Therefore, the study offers interesting insights on the empirical evidence on the lessons learned from continuous improvement practices in order to support managers on better decision making and for the academics on better understanding continuous improvement drivers.Originality/value: The present investigation provides a conceptual framework for future studies related to the sustainability of continuous improvement in industry, approaching this topic from a theoretical and practical perspective.

There is low adoption of Information Technologies (IT) in the administration of small bovine production systems which causes that most decisions are made based on the experience of the administrators and not based on data. This study proposes a methodological strategy to improve the adoption and appropriation of a Decision Support System (DSS) in the aforementioned kind of systems. The strategy includes gamification elements in the training supported in three IT tools, which help with the understanding of the connection between the tools. The tools are a simulation model, a serious video game, and the DSS. The design and development of the strategy used Design and Development Research and Case Study, System Dynamics to develop the simulation model and a Rational Unified Process to develop the serious video game and the DSS. The methodology was implemented in Santander, Colombia with informative sessions and working with producers in aided simulated environments with the goal of getting participants to use the proposed tools in their environments in a voluntary, autonomous, lasting way. Results showed the impact of the ludic and pedagogical components for the appropriation of the technology. 22 months after finishing the aided sessions 34% of the farmers show appropriation of the DSS and use it on their farms.

Digitization in Industry 4.0 is a key trend in a modern company’s development. However, business practice shows that digitization can be associated not only with the prospect of development but with numerous limitations that a company may struggle with. The goal of this manuscript is to verify the existence and identify of the management gaps that lead to formation of digitization problems in companies under the conditions of Industry 4.0. Management gap is understood here as a set of discontinuities, identified within management functions, which result in specific problems in the implementation of digitization projects. In general, this aspect is omitted in the literature on the subject, which focuses on benefits of implementing Industry 4.0 technology. The chosen goal of the manuscript is part of the research trend related to the identification of general digitization problems and to a company’s development, taking into account the use of technological solutions, as well as to the scope of research on the problems of implementing ICT projects. The development of an enterprise is understood as the ability to improve an organization both in the face of internal challenges and the environmental with maintaining innovation potential. The research structure is based on the construction of a conceptual model of management gaps and its empirical verification. In the theoretical part, the chosen research method is analysis of literature from the last 20 years and in the practical part analysis of a business case supplemented with an in-depth interview conducted among the management of the analyzed company. In the theoretical part, the article defines basic concepts related to Industry 4.0 and digitization of companies. It presents the place and role of digitization and its impact on the blurring of boundaries of traditional management layers. Based on these considerations, a conceptual model is developed defining management gaps within which problems of digitization of enterprises are indicated. The practical part of the article presents an empirical verification of the existence of the formulated management gaps on the basis of a business case analysis. The case study describes a mass, geographically dispersed implementation of the application for 34,000 users, which is the result of the implementation of the digitization strategy. Conclusions were formulated in the last part of the manuscript. On the theoretical ground, the analysis confirms that the process of digitization in an enterprise under the conditions of Industry 4.0 is related to blurring the boundaries of operational, tactical and strategic management. The premises of the said blur are identifiable and appear in each of the above-mentioned layers. On the practical ground, the existence of reasons for blurring the boundaries of management is related to the need to adapt the organization to the new operating conditions related to Industry 4.0. The strategic activities should be targeted at determining the directions of company improvement, which should precede the efforts to implement advanced solutions in the field of Industry 4.0. This approach allows providing a sustainable company development with the possibility of creating short-term effects and maintaining a long-term growth perspective.
