Modeling And Simulation Of Boiler Superheated Steam Temperature System Based On System Dynamics, Le Wei, Yuanyuan Yan
Journal of System Simulation
Abstract: Based on the principle of system dynamics, from the perspective of mass and energy conservation, taking the causal loop diagrams and the stock and flow diagrams as the carriers, and starting from the running mechanism of the system, the system dynamics model for the boiler superheated steam temperature system was established. This model has clear structure and reasonable complexity. By using the high temperature super-heater of the 300 MW boiler-turbine unit of Hebei Qingyuan Power Plant as the research object, simulation studies were carried out in Vensim PLE environment. The simulation curves were compared with the curves of …

Simulation Research For Highway Maintenance Management System Based On System Dynamics, Zhang Hong, Fangmin Ren, Rongbei Zheng
Journal of System Simulation
Abstract: It is necessary to study the long-term and dynamic relationships between highway maintenance efficiency and stakeholders, thus helping decision-making on the policies and maintenance plans around the highway maintenance issue. Based on analyzing dynamics and complexities of highway maintenance system, the system dynamics model for the highway maintenance simulation system was established. This study was aimed at simulating and evaluating the long-term dynamic relationships of the interactions among the highway pavement performance, operator's maintenance plans, users' satisfaction and administration department's budget allocation scheme for a long time period. The effectiveness and application of the proposed model were demonstrated …

Energy Conservation And Emissions Reduction Policy Simulation About Energy-Consuming Enterprises, Yongbo Yang, Chen Ying, Yang Jing, Mingzhong Liu, Zhenchao Jiang, Zeng Rong
Journal of System Simulation
Abstract: Energy conservation and emissions reduction policy have made some achievements, at the same time there are still some problem such as too much administrative command, lack of market mechanism and the lack of price mechanism. The government is both energy conservation leader, supervisor also rule makers. In order to formulate energy conservation policy, they must have overall cognition on energy conservation and emissions reduction. The dynamic relationship between the government, enterprise and environment was analyzed setting up simulation model for key energy-consuming enterprises based on system dynamics. Through the simulation, the influence of different policies for energy conservation …
Analysis Of Evolutionary Game Of Stakeholders In Service-Oriented Manufacturing Project Governance, Benhong Peng, Xiaofen Gu, Lu Qian
Analysis Of Evolutionary Game Of Stakeholders In Service-Oriented Manufacturing Project Governance, Benhong Peng, Xiaofen Gu, Lu Qian
Journal of System Simulation
Abstract: For the project governance of service-oriented manufacturing, there are three stakeholders, namely core manufacturer, customer, and service provider. Stability of three participants' evolutionary game was analyzed, the evolutionary game model was constructed and the dynamic game process of three - party Strategy Selection was studied by means of system dynamics simulation. Research shows that three participants eventually reach a steady state, which is core manufacture supervising, customer joining in, and service provider working hard; customer pays more attention to insured factors when choosing strategy; service provider's endeavor does not always aggrandize customer's expected revenue; The core manufacturing should fix …
Modeling And Simulation For Prevention And Control Of Drug Abuse And Drug-Related Crime Based On System Dynamics, Liu Feng
Journal of System Simulation
Abstract: In the existing drug abuse dynamics models, the drug users are assumed to be permanent immune to drugs after rehabilitation and the possibility of the recovery drug users being susceptible again is neglected. To solve the problem, through the system dynamics (SD) method, the evolution process of the drug-related crowds is analyzed, and a relevant model based on the transient immunity is constructed. The trends of the drug abuse and drug-related crime are predicted by the simulation experiments, and the sensitivity analysis indicates that the rate of contact and exposure to drugs is the most sensitive factor of the …

System Dynamics And Multi-Agent Simulation Research On Ground Combatpersonnel Attrition, Xiaoxiong Hao, Jianwei Ma, Zhaohui Huang, Yungui Wang
Journal of System Simulation
Abstract: In order to study the law of the combat personnel attrition and guide the military medical logistics support, the relevant researches are systematically sorted out and the key questions are clarified. Based on Lanchester equation theory, a system dynamics model of the combat attrition process is established, and the consistency between the model conclusion and the historical experience is analyzed. A multi-agent model of the combat attrition process is also constructed, and the advantages and disadvantages of the two models are analyzed. The main conclusion is that the theoretical model’s outcomes of combat attrition are relatively consistent with the …
