“…Niyonkuru and Wainer 125 introduced the concept of Digital Quadruplet to improve the development of Embedded Real-Time Systems: a 3D virtual replica of the real world under study (which is called here the DT), a discrete-event formal model of the system of interest that can be used for formal analysis and simulation studies (called the Triplet), and a physical model of the real system under investigation for experimentation (called Quadruplet).…”

As digitalization is permeating all sectors of society toward the concept of “smart everything,” and virtual technologies and data are gaining a dominant place in the engineering and control of intelligent systems, the Digital Twin (DT) concept has surfaced as one of the top technologies to adopt. This paper discusses the DT concept from the viewpoint of Modeling and Simulation (M&S) experts. It both provides literature review elements and adopts a commentary-driven approach. We first examine the DT from a historical perspective, tracing the historical development of M&S from its roots in computational experiments to its applications in various fields and the birth of DT-related and allied concepts. We then approach DTs as an evolution of M&S, acknowledging the overlap in these different concepts. We also look at the M&S workflow and its evolution toward a DT workflow from a software engineering perspective, highlighting significant changes. Finally, we look at new challenges and requirements DTs entail, potentially leading to a revolutionary shift in M&S practices. In this way, we hope to foster the discussion on DTs and provide the M&S expert with innovative perspectives.

“…28 A scaling factor can be provided, transforming hours into minutes, minutes into seconds, etc. This is important when incorporating hardware in the loop to the virtual framework 32 since, for instance, the previous use case handles periods of 30 min, but we may want to perform tests with sensors sending data every minute. In addition, xDEVS can interrupt the real-time simulation with the arrival of data sent by an external hardware device.…”

Simulation-driven engineering for the management of harmful algal and cyanobacterial blooms

et al. 2023

Harmful algal and cyanobacterial blooms (HABs), occurring in inland and maritime waters, pose threats to natural environments by producing toxins that affect human and animal health. In the past, HABs have been assessed mainly by the manual collection and subsequent analysis of water samples and occasionally by automatic instruments that acquire information from fixed locations. These procedures do not provide data with the desirable spatial and temporal resolution to anticipate the formation of HABs. Hence, new tools and technologies are needed to efficiently detect, characterize and respond to HABs that threaten water quality. It is essential nowadays when the world’s water supply is under tremendous pressure because of climate change, overexploitation, and pollution. This paper introduces Discrete Event System Specification-BLOOM, a novel framework for real-time monitoring and management of HABs. Its purpose is to support high-performance hazard detection with model-based system engineering and cyber-physical systems infrastructure for dynamic environments.

“…For instance, Lu and Olofsson 35 proposed an integrated framework to support the development of construction simulation models utilizing the advanced capabilities of Building Information Modeling (BIM) systems. A more advanced example is presented in Niyonkuru and Wainer, 36 which introduced an environment that can integrate simulation modeling with BIM visualization capabilities to develop real-time executable simulation models. Pen ˜a-Mora et al 37 suggested the use of hybrid modeling of DES and System Dynamics (SD) to abstract different levels of management in constructions systems.…”

A case study on the use of a conceptual modeling framework for construction simulation

et al. 2021

Construction simulation has been an active area of research in the last six decades. Nevertheless, there has been a gap between academia and industry in realizing the capabilities of simulation to support decision-making in construction. One of the well-recognized reasons is the difficulty of undertaking comprehensive simulation studies by construction practitioners, who usually lack sufficient knowledge and skills to adequately build simulation models. Efforts to bridge this gap have been focused on simplifying the computer coding and model implementation stages of construction simulation studies with limited research on the early stage of defining the model and abstracting the system, i.e., conceptual modeling. The conceptual modeling stage is known to be one of the most difficult tasks in a simulation study. Thus, several frameworks to support building conceptual models have been proposed in simulation literature. This study contributes to the research efforts to promote simulation in the construction industry through the adoption of a conceptual modeling framework. It demonstrates the application of the proposed conceptual modeling framework in a case study of piling operations. The findings of this paper reinforced the significance of conceptual modeling by confirming the role of the conceptual model as a communication link between stakeholders. Moreover, the conceptual model was used as a specification document for developing a flexible model that can be replicated in other settings. The use of a documented conceptual model assisted in managing the overall simulation study efficiently, which, in turn, lead to reductions in time and effort for different modeling activities.
