“…For example, achieving zero emissions may require the use of battery electric machines, which necessitate more frequent and longer charging times compared to refueled equipment. Additionally, automation is expected to play a significant role, especially in sites with mixed traffic and partial automation, necessitating a different design approach (Frank, 2019;Wickberg et al, 2022).…”

“…The main challenge is acquiring the required accuracy with the increased number of simulated machines, tasks, and facilities, creating a trade-off between accuracy and feasibility. This work is motivated by two aspects: first, the current simulation tools are limited in their ability to provide a comprehensive site simulation due to their high computational cost (Guo & Zhang, 2022), and the huge amount of involved elements that can be in a site (Wickberg et al, 2022). Second, the decision-making process for designing and operating construction and mining sites is heavily based on experience rather than data-driven or standard insights.…”

The Construction and mining Industry comprises complex operations and interactions between various actors at different levels. Simulation has emerged as a valuable tool in this domain to better understand the site's behavior and optimize its operation. However, developing a simulation platform that can handle all the operations on the site is challenging due to the computational cost of the digital representation of reality along with the required accuracy level.This paper aims at extracting and mapping the optimization requirements of construction sites at three main levels: site level, operational level and dynamics level. More precisely, this work seeks to define and map the most important requirements between these levels that ensure simulation credibility and reliability.Based on interviews with experts in the domain, both from academia and industry, several key insights and recommendations emerged: at the site level, the layout and the key performance indicators, such as productivity, time, cost, number of machines and workers, need to be modeled and simulated. At the operational level, the simulation platform must include the main activities, such as loading, excavating, transporting and dumping. Moreover, the dynamics level should involve machine models and their interactions with the site's environment, such as earthmoving, drilling, excavating and blasting.
