The concept of Industry 4.0 is characterized by the era of digitization. Business models, environment, production systems, products and services interconnects in the Industry 4.0 environment. The quality of changes in production processes reflects in the fact that the entire production process is managed and supervised in an integrated way that is combined and flexible. Manufacturing companies must constantly evolve their production systems and meet the changing demands of the market to stay competitive in a globalized environment.  The current industry brings a new accepted point of view in the processes of digital technology application in the fields of logistics and manufacturing. Most of its application relates to automation processes where human work and modern information and communication solutions and services are replaced. For this reason, the concept of Industry 5.0 is appeared recently. The current research areas of Industry 4.0 and Industry 5.0 are not sufficiently focused on the possibilities of developing and applying forms of assistive technologies and services in terms of inclusion of persons with disabilities in work processes. Assistive technologies contribute to raising the quality of life of people with disabilities. The aim of this paper is to represent the extent to which assistive technologies are used in the concepts of Industry 4.0 and Industry 5.0 and what are the challenges of implementation of such technologies. The paper will also represent the opportunities that people with disabilities can do with the help of assistive technologies in smart factories.

Transport calls for reliable, robust and efficient, but less expensive solutions. To respond to this call, engineers keep improving means of transportation in all their aspects. A particularly interesting possibility that attracted numerous researches in the previous two decades is related to active behaviour of transport means. This also includes their load-carrying structures. Integration of classical, passive structures and multi-functional material based active elements resulted in a novel concept of structural design denoted as active, adaptive, or smart structures. The distinguishable property of the concept is self-sensing and actuation coupled by control capabilities so that a number of additional functionalities are enabled such as vibration suppression, noise attenuation, structural health monitoring, shape control, etc. Those functionalities offer immense advantages over passive structures, which is reflected in improved robustness, safety and efficiency in their application.
Work in this attractive field of research covers: 1) innovative solutions regarding design of active structures and their elements, 2) development of modelling and simulation tools. When it comes to the latter group of tasks, finite element method, as the most powerful method in the field of structural analysis, is most frequently addressed. Various types of finite elements have been developed for modelling and simulation of coupled-field effects intrinsic for active structures. In this specific work, such elements are combined with a newly developed simulation tool that enables interactive, real-time simulation of active structures. Strain rate proportional damping is implemented to produce active vibration suppression. A few academic cases of shell and truss structures together with a model of a tower crane demonstrate the developed simulation tool and the feasibility of active structure concept.
