Age replacement policy in the case of no data: the effect of Weibull parameter estimation
Sgarbossa, Fabio; Zennaro, Ilenia; Florian, Eleonora; Calzavara, Martina (Peer reviewed; Journal article, 2019)Age replacement is a common maintenance policy when wear-out failures occur, and it is characterised by periodic replacement of components. Data on time to failure (TTF), often modelled with the Weibull function, are ... -
Ageing workforce management in manufacturing systems: state of the art and future research agenda
Calzavara, Martina; Battini, Daria; Bogataj, David; Sgarbossa, Fabio; Zennaro, Ilenia (Journal article; Peer reviewed, 2019)The workforce ageing phenomenon is recently affecting most of the Organisation for Economic Co-operation and Development (OECD) member countries, due to a general ageing of their populations and a higher average retirement ... -

Cost modelling of onboard cobot-supported item sorting in a picking system
Fager, Patrik; Calzavara, Martina; Sgarbossa, Fabio (Peer reviewed; Journal article, 2020)For manual picking processes in warehouses and assembly line feeding, collaborative robots – cobots – hold a potential to support operators and, thereby, enhance performance. However, studies focused on the economic aspects ... -
Including rest allowance in mixed-model assembly lines
Finco, Serena; Calzavara, Martina; Sgarbossa, Fabio; Zennaro, Ilenia (Journal article, 2020)Ergonomics has a significant impact on productivity and human safety in manual assembly lines. For this reason, several studies in recent years have proposed including ergonomics in assembly lines. However, most works are ... -
Kit preparation with cobot-supported sorting in mixed model assembly
Sgarbossa, Fabio; Calzavara, Martina; Fager, Patrik (Journal article; Peer reviewed, 2019)Kitting is a common approach of materials supply with mixed-model assembly, by which components are supplied to the assembly process in pre-sorted kits. With kitting, the kit preparation is a labour intensive process and ... -
Modelling time efficiency of cobot-supported kit preparation
Fager, Patrik; Calzavara, Martina; Sgarbossa, Fabio (Peer reviewed; Journal article, 2020)Kitting – meaning to supply assembly with components in presorted kits – is widely seen as beneficial for assembly quality and efficiency when there is a multitude of component variants. However, the process by which kits ... -
Throughput models for a dual-bay VLM order picking system under different configurations
Sgarbossa, Fabio; Calzavara, Martina; Persona, Alessandro (Peer reviewed; Journal article, 2019)Purpose Vertical lift module (VLM) is a parts-to-picker system for order picking of small products, which are stored into two columns of trays served by a lifting crane. A dual-bay VLM order picking (dual-bay VLM-OP) ... -
Vertical Lift Modules for small items order picking: an economic evaluation
Sgarbossa, Fabio; Calzavara, Martina; Persona, Alessandro (Journal article; Peer reviewed, 2019)Small items order picking is a very labour-intensive activity which is often performed in a dedicated area equipped with carton racks and with the operators walking within the aisles to pick the required products. Recently, ...
