It is proposed to apply Statis...
The era of Industry 4.0 (I4.0) requires technology and engineering higher education institutions to provide their students with the competences inherent to this evolution. This requires teaching staff training, but first, naturally, teachers' level of competences must be assessed. The objective of this work is to assess the current level of teachin...
Since 1990, attempts to implement lean, especially by production companies, have grown in number and depth. With the publication of the book Lean Thinking, lean projects quickly spread to other activity sectors, but achieving success in such implementations is not something that can be easily accomplished. Research is in progress to identify why so...
Training operators in industrial contexts is a demand that most of the industrial organizations must deal with, and engineers are the trainers in many cases. Thus, engineers may be required to deal with the development of a training environment and a competences assessment system in training settings. This paper aims to characterize strategies for...
It is usual that companies must develop their own training processes, adaptable to their own production systems. In fact, the evaluation of the training process is a function of significant importance and must guarantee means for the identification of demands for corrective actions and for a procedure that ensures the continuous evolution of the pr...
In many areas, there is a multitude of terms/designations and definitions for the same concept, leading thus to misunderstanding. This also occurs with the designated Lean Production, which started to be known as a “thing” from the shop floor. However, it was quickly realized that it is much more than that (and should be understood as much more), o...
The number of publications on improving office and knowledge work processes is quite low compared to the vast body of published work regarding the improvement of production processes. In fact, the very definition of the office and knowledge work concept is not consensual. Besides a discussion on this concept, this paper aims to present a straightfo...
