Complex system has evolved from single domain and discipline system into multi-domain and multidisciplinary giant composite system, with the characteristics of large-scale and local-global interaction complexity. The introduction of complex system quantitative and qualitative synthetic M&S and evaluation technology, which integrates complex system related professional field technology, M&S...
Under the guidance of the theories of Complex Adaptive System and Artificial Societies, modeling and simulation of international politics evolution in crisis was studied. The Model of International Politics Evolution (IPEM) in crisis based on Agent was built. The function and architecture of IPEM were introduced. Individual Agent, including Nation Agent, International Organization Agent and Environment...
In this paper, receding horizon control of large-scale sewage systems is addressed considering different modelling approaches, which include several inherent continuous/ discrete phenomena (overflows in sewers and tanks) and elements (weirs) in the system. This fact results in distinct behaviours depending on the dynamic state (flow/volume) of the network. These behaviours can not be neglected nor...
In mathematical/statistical modeling of complex systems, the locations of the data points are essential to the success of the algorithm. Sequential design methods are iterative algorithms that use data acquired from previous iterations to guide future sample selection. They are often used to improve an initial design such as a Latin hypercube or a simple grid, in order to focus on highly dynamic parts...
Urban traffic systems are usually complex systems which require dedicated modeling methodologies. In this paper, the "traffic flows" in the urban traffic systems is modeled as continuous variable dynamic systems (CVDS) and the "decision maker + traffic lights" of the traffic systems is modeled as discrete event dynamic systems (DEDS). So the entire urban traffic system can be modeled...
System of systems (SoS) concept is essential in solving the issues in complex systems where there are heterogeneous independently operable systems. Each system should be modeled in a model-based controller. The problem of mathematical modeling of a single system is considered. This system can be a part of a SoS, working independently from other systems. In this paper we have described the main steps...
