“…Predicting future performance and providing feedback when designing real-world systems or products is the key purpose and primary advantage of simulation activities (Ouyang, 2014). Prior to actual construction or production, simulation allows stakeholders to determine the efficiency of a product or system (Antonelli et al, 2018) and enables designers to investigate problems in a wide range of scenarios (Zhu et al, 2017). This is equally true in building design (Kotireddy et al, 2018;Kneifel and O'Rear, 2017;Nguyen et al, 2014).…”

The expanding use of IT has brought an increase in productivity to the world of business, industry and commerce. However, this is not mirrored by an equivalent growth in the use of IT by aid agencies in post-disaster situations. We report a pioneering two-stage study which tested the appetite for the increased use of computational IT tools in this sector, assessed their level of usefulness and whether they can be practically implemented. Thirty aid workers across nineteen countries were surveyed on their use of IT and computational tools in shelter design and provision. The key finding was that none of the participants used any building simulation tools or software packages in any of the design stages of shelter construction. Using this result, two example tools were created-one assessing daylighting and the other environmental impact. A second survey involving 48 aid workers was then carried out to record their experience of using the new tools and 97% of the participants identified a need for such shelter design tools. The majority felt that the new tools were useful and that they would like to use similar tools in their work, most of them preferring tools in the form of web applications. It is concluded that humanitarian workers in the shelter sector are very willing to adopt IT-based computational tools in their work and would appreciate doing so, but only if they have access to suitably simple tools which are quick to use and easy to learn.

“…The system dynamics model emphasizes the interaction, connection and dynamic evolution process between watershed ecosystems [28] . The research problem is described by a causality diagram consisting of interconnected feedback loops [29] . The evaluation index of watershed ecological security was research from the perspective of system dynamics to define the potential impact factors that threaten the ecological security of the basin within a certain spatio-temporal window.…”

As an important energy base and ecological barrier in China, the ecological security of the Yellow River Basin has a very important strategic position in the pattern of high-quality development, but it is threatened by human activities and climate change. In order to evaluate the degree of ecological security in the Yellow River Basin and clarify the influencing factors of ecological security, this paper discusses the advantages and disadvantages of the existing ecological security assessment methods and models. On this basis, the system dynamics model is used to describe the process of ecological security threats, identify the key factors that threaten ecological security, and then sort out the ecological security assessment indicators. The ecological security assessment model composed of pressure(P), state(S), hidden dangers(D), response(R) and management (M) (PSDRM) indicators is constructed, and the ecological security assessment methods and processes are improved to provide theoretical guidance and technical support for improving the ecological security assessment of the basin.

“…Parallel discrete event simulation became the logical choice process, linking complex system modeling and highperformance computing. Therefore, a hierarchical composite modeling framework, a three-layer architecture designed, can support the composition and integration of submodels [3]. The network agent-based modeling method can generate a dynamic spatial network structure and collaborative network and complex system theory to simulate forest space complex systems [4].…”

With the change in coal supply and demand, the dynamics of multiple transit nodes and the connection between different transportation modes make the Coal Multimodal Transportation System (CMTS) more complicated in the long-distance transportation of coal. Therefore, it is necessary to analyze the multimodal transportation nodes, build a coal multimodal transportation model, measure the network throughput through simulation experiments, and identify system bottlenecks. The CMTS is a complex nonlinear dynamic system with many participants with complex and uncertain links. Different transportation modes, operation links, and connection processes will affect system performance, and modeling and simulation technology effectively study complex dynamic systems. This paper takes the CMTS as the research object, uses agent-based modeling methods and Witness simulation software to analyze the composition and operation mechanism of CMTS, establishes the multiagent model of CMTS, and validates the model by a Witness simulation experiment of northern coal shipped to south. The simulation results indicate the capacity of the transport route and resource utilization of nodes in CMTS in case of different demand growth rates in the future. Based on the multiagent model and Witness simulation results, this paper provides practical support for constructing and applying the multimodal transport system model library and provides the basis for decision-making for the CMTS plan.
