Abstract
The aim of this study was to apply the System-
Theoretic Process Analysis (STPA) method to an autonomous
factory setting and examine its suitability. Additionally, the research
explores the potential of STPA for identifying safety concepts that
enable safe operations in mixed fleets. The case study consists of
three scenarios in which different numbers of Autonomous Mobile
Robots (AMRs) operate autonomously alongside and without a
human operator on factory modules. Factory modules refer to units
designed to perform specific functions or tasks. The objective of
the STPA was to identify loss scenarios that arise due to collisions
between AMRs, AMRs and humans, as well as AMRs, human
operators, and the factory infrastructure. The study identified that
while the inherent safe design of AMRs is crucial, comprehensive
system safety can be significantly enhanced by fleet control’s route
selection and operational protocols. It shares insights on how
systems and fleet controls could be designed to promote safe mixed
fleet operations.
