Model Vision Language allows describing the continuous-time part of the model combining the use of equations (i.e., a causal modeling) and sequences of assignment statements. The hybrid behavior is described using behavior charts (B-chart). A B-chart is a diagram consisting of modes, transitions internal to the modes and transitions between modes. The activity of the mode is specified by a local class (the so-called activity class of the mode) that describes the system structure and behavior while in this mode. The system of equations that describes the complete model at certain time is automatically built by RMD at run time. Every time a transition takes place (i.e., the model structure changes), RMD constructs the mathematical description of the actual model, eliminates the redundant variables and trivial equations resulting from component connections, analyzes the model solvability and structure, selects the best-suited numerical method and generates the input to this numerical method. This approach provides high flexibility in the description of variable structure models. This feature is demonstrated using variable structure models arisen in two different applications. The first application is the run-time change in the selection of the model state variables. Support for several selections of the state variables is typically required in interactive simulations. The second application is the description of systems with variable behavior. The model of an industrial boiler is used to illustrate the description of this type of variable structure models.","PeriodicalId":386945,"journal":{"name":"2013 8th EUROSIM Congress on Modelling and Simulation","volume":"26 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123578971","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In social science, no firm conclusions have been reached on the appropriate way to verify or validate Agent Based Models, due to several aspects, such as agent capacity to take decisions autonomously. This paper considers some of the difficulties in establishing verification and validation of agent based models, and proposes the use of coloured petri net formalism to specify agent behaviour in order to check if the model looks logical and the model behaves logical. Model plausibility is used to express the conformity of the model with a priori knowledge about the process. The proposed methodology has been applied in the European Future Policy Modelling project (www.fupol.eu) to create trust and increase the credibility of the agent based models developed to foster e-participation in the design of urban policies by means of simulation techniques.","PeriodicalId":386945,"journal":{"name":"2013 8th EUROSIM Congress on Modelling and Simulation","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114825861","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Efficient operation requires a fast start-up and reliable operation in varying cloudy conditions without unnecessary shutdowns and start-ups. Fast and well damped linguistic equation (LE) controllers have been tested in Spain at a collector field, which uses parabolic-trough collectors to supply thermal energy in form of hot oil to an electricity generation system or a multi-effect desalination plant. Control is achieved by means of varying the flow pumped through the pipes in the field during the operation. Solar energy can be collected only when the irradiation is high enough. The nights and the heavy cloud periods need to come up with the storage. The LE controllers extend the operation to varying cloudy conditions by using predefined model-based techniques and activating special features to react well to operation requirements and disturbances. The latest test campaign focused on achieving a smooth operation in changing operating conditions. Fast start-up, smooth operation and efficient energy collection is achieved even in challenging situations: cloudy conditions and load disturbances are handled efficiently. A trade-off of the temperature and the flow is based on model-based optimisation to achieve a good level for the collected power. The working point is chosen in a way which improves the efficiency of the energy collection and problematic operating conditions are removed by limiting the acceptable range of the working point.","PeriodicalId":386945,"journal":{"name":"2013 8th EUROSIM Congress on Modelling and Simulation","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125349285","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The urban environment is a network that exists among different structures, links, flows and relationships. The spatial distribution and development direction of the territory, also business environment development is determined by a street network and transport communication network. This information is well formed in GIS models. As the GIS models are static, they cannot be used to determine any dynamics of the territory, however, the urban environment is nonlinear. A possible way to solve nonlinearity is to prepare geosimulation models, as they are more informative for dynamic processes than GIS models. Geosimulation models also allow making experiments and solving optimization tasks. `The automatic creation of geosimulation models does not require deep knowledge of simulation techniques for domain specialists further using them.","PeriodicalId":386945,"journal":{"name":"2013 8th EUROSIM Congress on Modelling and Simulation","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125567774","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The seed bank density of the weed population and frequencies of resistant and susceptible alleles are taken as the state variables of the growing cycle. The control variable is taken as the application doses. The goal is to reduce herbicide use, maximize profit in a pre-determined period of time and minimize the environmental impacts caused by excessive use of herbicides. The optimization problem of finding the application doses is solved with a dynamic programming approach which takes into account the decreased herbicide efficacy over time due to weed resistance evolution caused by a selective pressure which varies with the applied doses. Numerical simulations for a case study with the Bidens subalternans frequent in a corn crop is presented. We used data from a green house experiment to obtain the weed response to the most widely used Atrazine herbicide. Also, the sensitivity of the optimum solution in terms of the key parameters in the seed bank dynamics that are highly influenced by environmental factors is analysed. This suggests that the optimizing solution features some robustness under a quite realistic assumption that there are imported seeds in the system.","PeriodicalId":386945,"journal":{"name":"2013 8th EUROSIM Congress on Modelling and Simulation","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128653833","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite promising results reported by companies that have adopted CPFR, the implementation of CPFR appears to have encountered some obstacles. It is proposed here that a lack of appropriate detailed information concerning the critical success factors (CSFs) in CPFR implementation is an important reason for this. Although, the CSFs for CPFR implementation vary due to differences in industries and characteristics of supply chain, it is vital that managers of firms are aware of these factors prior to the adoption of CPFR with trading partners. This paper goes some way toward, narrowing of this gap by identifying CSFs in the automotive spare part industry. In order to complete this task, a comprehensive review of related CSF literature was conducted with factors recorded and classified. Following this, experts' views and perceptions were applied to identify relevant CSFs. Fuzzy Extent Analytical Hierarchy Process (FEAHP) approach was then applied to weight selected elements and sub elements. Finally, the top ten critical factors for CPFR implementation were identified. The results of this study are expected to provide specific decision making principals for automotive spare part manufacturers to adoption of CPFR. To our knowledge, this is the first study that analyses CPFR success factors in automotive industry.","PeriodicalId":386945,"journal":{"name":"2013 8th EUROSIM Congress on Modelling and Simulation","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132446271","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This approach combines the global search ability of DE and the local search ability of adaptive system with migration parallel GA. The proposed algorithm incorporates concepts from DE, PSO, PGA and neural networks (NN) to facilitate the adaptive control of parameters.
