Abstract
Due to increasing competition in the global market and to meet the need for rapid changes in product variability, it is necessary to introduce self-configurable and smart solutions within the entire process chain, including manual assembly to ensure the more efficient and ergonomic performance of the manual assembly process. This paper presents a smart assembly system including newly developed smart manual assembly workstation controlled by a smart algorithm. The smart assembly workstation is self-configurable according to the anthropometry of the individual worker, the complexity of the assembly process, the product characteristics, and the product structure. The results obtained by a case study show that is possible to organize manual assembly process with rapid adaptation of the smart assembly system to new products and workers characteristics, to achieve ergonomic working conditions through Digital Human Modelling (DHM), to minimize assembly time, and to prevent error during the assembly process. The proposed system supports the manual assembly process redesign to ensure a better working environment and aims to have an important value for applying the smart algorithms to manual assembly workstations in human-centered manufacturing systems.

Summary
Manufacturing is a process of converting raw materials into finished goods through a production process involving machines, tools and labor (human worker) [1]. With the I4.0 paradigm, the “smart” has been considered as a core characteristic of the future manufacturing system [2]. The manufacturing industry has gone through many changes, especially in the way of the liberation of human manual labor, [2] but manual work is, and in future will be, an important component of production in any industry, because it is directly related to the productivity of the system. The abilities, skills, productivity and performance of the workers have great importance for the increase of production [6,7,8], so there is a need to develop a multi-skilled workforce capable of performing multiple tasks [9] or to develop a worker-centered system with digital instructions [10,11].
