Urban Development Simulator: An interactive decision support tool for urban planners enabling citizen’s participation.

The Urban Development Simulator is currently under development within the FP7 EU project urbanAPI (2011-2014). The simulation tool is developed for the city of Ruse in remote northern Bulgaria at the Romanian border as a support for the local urban planners and politicians to evaluate high level planning decisions defined as use cases. The tool is developed as generic simulation framework, thus the framework can be applied for other cities too, to generate tailor-made urban planning support tools, if the necessary geospatial data about future planning scenarios and related statistical data describing the socio-economic state and future expectations are available. The tool enables urban planners to estimate the impact of different urban development scenarios and visualises spatial changes through dynamic GIS maps depicting the results of the simulations. It is based on the analysis of geospatial data and uses an Agent-based modelling approach to simulate the development in the city. While other urban development simulation tools usually model urban growth in the urban fringe, the Urban Development Simulator concentrates on intra-urban development, as the City of Ruse turns out as a shrinking city which is starting to recover since the last years – reorganizing the intra-urban structure. The tool has a complex user interface and a web interfaces to interact with the local citizens. Thus different planning scenarios and their effects can be visualized (also in 3D) via the web interface and the opinion of the local residents can be involved into the planning decisions by voting for selected planning decisions as preference of the citizens. The spatial pattern of the preferences serves as an input for the parameterization of the Agent-based model to simulate the development trends within the different areas of the city. Scenarios can be simulated what would be, if the urban planners would follow the citizens’ preferences. This enables the decision makers to adapt their urban development plans by considering the preferences of the citizens. Effects on e.g. the final energy demand and CO2 emissions for residential buildings are further calculated for the different development scenarios. The model runs as a Java web-start application and is hosted on a server at the AIT with remote access for the Ruse users. For the model development the simulation platform MASGISmo (Multimethod Agent-based (ABM) System dynamics (SD), GIS modelling platform) has been applied, a framework originally developed during several prior projects to combine a bottom up agent-based simulation method (ABM) with a top down – system dynamics (SD) approach. This platform is programmed in Java connected to several external tools as a PostgreSQL (PostGIS) database, Vensim a (SD) tool and uses RepastJ as core ABM tool. For the purpose of the Urban Development Simulator the GIS capability of the platform was enhanced with more powerful GIS features, thus new planning scenarios can directly be introduced within the tool by the urban planners. The paper will concentrate on the description of the structure of the Urban Development Simulator, further more explain the participatory citizen’s integration

Integration of decision support systems to improve decision support performance

Decision support system (DSS) is a well-established research and development area. Traditional isolated, stand-alone DSS has been recently facing new challenges. In order to improve the performance of DSS to meet the challenges, research has been actively carried out to develop integrated decision support systems (IDSS). This paper reviews the current research efforts with regard to the development of IDSS. The focus of the paper is on the integration aspect for IDSS through multiple perspectives, and the technologies that support this integration. More than 100 papers and software systems are discussed. Current research efforts and the development status of IDSS are explained, compared and classified. In addition, future trends and challenges in integration are outlined. The paper concludes that by addressing integration, better support will be provided to decision makers, with the expectation of both better decisions and improved decision making processes

Principles and Concepts of Agent-Based Modelling for Developing Geospatial Simulations

The aim of this paper is to outline fundamental concepts and principles of the Agent-Based Modelling (ABM) paradigm, with particular reference to the development of geospatial simulations. The paper begins with a brief definition of modelling, followed by a classification of model types, and a comment regarding a shift (in certain circumstances) towards modelling systems at the individual-level. In particular, automata approaches (e.g. Cellular Automata, CA, and ABM) have been particularly popular, with ABM moving to the fore. A definition of agents and agent-based models is given; identifying their advantages and disadvantages, especially in relation to geospatial modelling. The potential use of agent-based models is discussed, and how-to instructions for developing an agent-based model are provided. Types of simulation / modelling systems available for ABM are defined, supplemented with criteria to consider before choosing a particular system for a modelling endeavour. Information pertaining to a selection of simulation / modelling systems (Swarm, MASON, Repast, StarLogo, NetLogo, OBEUS, AgentSheets and AnyLogic) is provided, categorised by their licensing policy (open source, shareware / freeware and proprietary systems). The evaluation (i.e. verification, calibration, validation and analysis) of agent-based models and their output is examined, and noteworthy applications are discussed.Geographical Information Systems (GIS) are a particularly useful medium for representing model input and output of a geospatial nature. However, GIS are not well suited to dynamic modelling (e.g. ABM). In particular, problems of representing time and change within GIS are highlighted. Consequently, this paper explores the opportunity of linking (through coupling or integration / embedding) a GIS with a simulation / modelling system purposely built, and therefore better suited to supporting the requirements of ABM. This paper concludes with a synthesis of the discussion that has proceeded.

Multi-agent framework based on smart sensors/actuators for machine tools control and monitoring

Throughout the history, the evolutions of the requirements for manufacturing equipments have depended on the changes in the customers' demands. Among the present trends in the requirements for new manufacturing equipments, there are more flexible and more reactive machines. In order to satisfy those requirements, this paper proposes a control and monitoring framework for machine tools based on smart sensor, on smart actuator and on agent concepts. The proposed control and monitoring framework achieves machine monitoring, process monitoring and adapting functions that are not usually provided by machine tool control systems. The proposed control and monitoring framework has been evaluated by the means of a simulated operative part of a machine tool. The communication between the agents is achieved thanks to an Ethernet network and CORBA protocol. The experiments (with and without cooperation between agents for accommodating) give encouraging results for implementing the proposed control framework to operational machines. Also, the cooperation between the agents of control and monitoring framework contributes to the improvement of reactivity by adapting cutting parameters to the machine and process states and to increase productivity
