Industry 4.0 technologies, such as enterprise wearables, can foster better industrial hygiene to keep operators healthy, safe, and motivated within emerging cyber-physical production systems. This paper provides an optimistic perspective on opportunities evolving from wearable devices in an Industry 4.0 workplace environment to support occupational health, safety and productivity for the Operator 4.0. Examples of technical solutions, and their associated application scenarios, are presented show...

Abstract Due to today’s technological advances in the area of Industry 4.0, having a strategy for cognitive automation solutions is crucial. Operator 4.0, will have handle and manage different work tasks ranging from learning new tasks to solving difficult problems and initiate changes. To support the operator moving between these tasks a specific strategy for the design of cognitive automation solutions is needed. The suggested strategy has three steps: (1) select assembly modes, (2) choose lev...

Abstract Disturbance handling is crucial for managing production complexity in final assembly. Due to that complexity in a system causes uncertainties and assembly errors, it is important to further investigate what causes disturbance handling and how it can be managed to support operators working with complexity. Production complexity was assessed through the method CompleXity Index (CXI), which captures operators’ view of a station. A statistical analysis of the CXI data was performed and rela...

This thesis provides insights on complex assembly issues and presents pragmatic models, methods, measurable parameters and prototypes that can be used to support operators in complex assembly. Assembly systems are complex partly because of a high degree of product variety and the strategy of having mass-customised products. Complex assembly causes product quality issues, uncertainties and poor ergonomics. Since stress and psycho-social health are emerging problems, it is important to further inv...

Production complexity causes assembly errors due to that the demands on the operators are high and there is a need to improve assembly instructions. Design principles for Information Presentation (DFIP) is a method developed to support such improvement and its application was evaluated in three case studies, 152 practitioners. Results indicate that DFIP use help simplifying the information presentation so that complexity can be reduced, and that step 4 is easiest to understand. In addition, the ...

Learning factories play an important role when studying multi-disciplinary problems. Such a problem is to support operators in multi-variant assembly. Multi-variants cause problems with product quality, production time as well as cognitive load and therefore it is important to find ways to support operators in this context. To assess the effects of multi variants, a design concept were developed in a learning factory environment (SIILab, CPPS-testbed). The concept was constructed at a conveyer b...

Operators remain as important resources in complex final assembly. To sustain a multi-variant production, it is necessary for operators to manage high demands from a cognitive workload perspective. In such situations, work instructions can support operators cognitively. However, work instructions are often insufficient or unused in final assembly. In this paper, results from testbed experiments are presented where assembly work was supported by different types of work instructions with differing...

There are several theoretical methods for assessment of assembly complexity but there are few practically applicable methods. One of the methods, CompleXity Index (CXI), aims at assessing operators´ perception of manual assembly complexity in running production. Another recently developed method, Basic Assembly Complexity (CXB) is intended for predictive assessment of basic manual assembly complexity in early product and production development. Both CXI and CXB aim to improve assembly conditions...

This article focuses on how operator wellbeing can be assessed to ensure social sustainability and operator performance at assembly stations. Rapid technological advances provide possibilities for assessing wellbeing in real-time, and from an assembly system perspective, this could enable the assessment of physiological data in real-time. While technology is available, it has not been implemented or tested in industry. The aim of this paper was to investigate empirically how concurrent physiolog...

As part of a global production strategy, many manufacturing companies locate their assembly plants in different countries around the world. While outsourcing final assembly closer to key markets has competitive benefits, these companies face new challenges with communication and dissemination of information. Concerning shop-floor operators specifically, these challenges affect the initial training and continuing improvement work instructions in particular. Emerging information and communication ...
