From the 14th to the 16th of December, Manuel Jungmann from TUB, one of the leading technology partners in the ASHVIN project, presented the project’s research at the Winter Simulation Conference WSC2022 in Singapore.
The published paper is entitled “Real-Time Activity Duration Extraction of Crane Works for Data-Driven Discrete Event Simulation”, authored by several ASHVIN partners (Manuel Jungmann; Lucian Ungureanu; Timo Hartmann; Hector Posada; Rolando Chacon).
The paper describes that the construction industry is struggling with low productivity rates because of a low level of digitalization, dynamic interactions, and uncontrollable circumstances on sites, which make the planning process complex. Usage of the digital twin construction paradigm enables to facilitate construction management and leverage the sector’s unexploited potential. This research addresses current shortcomings by real-time discrete event simulation. During crane operations, kinematic data were collected, which were classified by machine learning algorithms for activity recognition and duration extraction. Based on the identified durations, Goodness-of-Fit techniques determined suitable probability density functions. The resulting probability density functions were used as input parameters in stochastic discrete event simulations. It was shown that with enriched data collection, probability density functions have to be updated. The data-driven discrete event simulation facilitates decision-making processes by providing more reliable real-time information for the planning of upcoming construction works. Thus, data-based instead of experience-based management can be enabled.
After more than 50 years after its inception, the Winter Simulation Conference was held in Asia for the first time. The theme of 2022 WSC is derived from Singapore’s Smart Nation initiative, “Singapore Reimagined.” The COVID-19 pandemic brought us a “new normal”, and technological advances in the fields of robotics, artificial intelligence (AI), biotechnology, Internet of Things, quantum computing, and virtual reality (VR) are changing the way humans live, work, play and communicate. Building on the “Smart Cities” focus of last year’s conference, 2022 WSC “Reimagine Tomorrow” to evaluate not just living in an urban future where cities are safe, green and environmentally-secure with seamless power, water and transportation networks, but also working in an environment where both sustainable high-tech manufacturing and novel services play an essential role.
