Abstract

Within the past few years, simulation and modeling have been adopted by the Architecture, Engineering, Construction, and Facility Management (AEC/FM) industry because it provides unique opportunities to transform traditional human-centered decision-making in design, planning, execution, and maintenance practices into simulation-centered decision-making. This allows a decision-maker to understand system behavior, and predict future events without having to test scenarios and interfere with the current operations of an existing system. However, a major challenge in transitioning from human-centered decisionmaking to simulation-centered decision-making is to establish methods and guidelines that facilitate seamless integration of field data into project planning, monitoring and control, and operation. This integration of field data into a simulation model allows the dynamics and evolving nature of events that may occur in a real system to be integrated into the simulation for effective decision-making. The goal of this paper is to conduct a vigorous review and investigate the underlying challenges associated with aspects such as modular design, data interfaces and translation, and model development and validation. In particular, this paper: 1) presents Discrete Event Simulation Specification (DEVS) as a simulation formalism that facilitates decision-making across a single operation (e.g. earthmoving); 2) reviews High Level Architecture (HLA) as a distributed simulation platform that allows for the coupling of several standalone simulation models and data sources to improve decision-making across complex systems; and 3) describes the hierarchy of multimodal data sources for simulation and different formalisms (i.e. model representations) that facilitate storage and querying of real time data to support simulation and distributed simulation models. The materials presented in this paper are the latest findings of an ongoing collaborative project being conducted by the Simulation Taskforce of the Visualization, Information Modeling, and Simulation (VIMS) Committee of the American Society of Civil Engineers (ASCE), and aim to lay the foundation for future research and implementation efforts in AEC/FM domain-specific real-time simulation systems. In the long term, work in this area will enable researchers to address some of the most fundamental problems in AEC/FM simulation modeling.
