Distributed Simulation of Processes in Buildings and City Models

引入建筑信息建模(BIM)是为了对建筑和基础设施的生命周期进行建模，并使它们可用于更高级别的问题。然而，环境模拟或城市和空间规划等苛刻的过程必须从地理信息系统(GIS)的意义上考虑，从单个建筑的微观层面开始，也从季度、整体和区域的微观层面开始。只有到那时，才能在不同的尺度上模拟与气候和环境有关的量的动态和影响。该建议的目的是提出在BIM/GIS环境下支持尺度重叠过程的分布式模拟的概念和方法。因此，新的数学和信息技术方法将开始应用。更明确地说，有限拓扑上的过程将以数学上合理的方式描述，并使用图论和p-进分析尽可能有效地运行。还应分别提供适用于跨细节或规模的分布式处理的标准实现、算法和可划分数据结构。使用拓扑学作为描述过程的无阶数视角，将给出新一代数据建模标准如IFC和CityGML的发人深省的推动力。最后，以一个典型的三维城市内热传播和建筑模型为例，验证了所开发的概念和软件的实用性。

Building Information Modeling (BIM) was introduced in order to modelthe life cycle of buildings and infrastructures, and to make themavailable for questions at a higher level. Demanding processes likeenvironment simulations or city and spatial planning, however, mustconsider in the sense of Geographic Information Systems (GIS),starting from the micro level of single buildings, also quarters, wholecities and regions. Only then can the dynamics and the influence ofclimate- and environment-related quantities be simulated in differentscales. The aim of this proposal is the conception and makingavailable of methods for supporting distributed simulations of scale-overlapping processes in the BIM/GIS context. Hereby, novelmathematical and information-technological methods shall come totheir application. More explicitly, processes on finite topologies are tobe described in a mathematically sound way and run as efficiently aspossible using graph theory and p-adic analysis. Regardingimplementations, algorithms and partitionable data structures are tobe provided which are suitable for a distributed processing alsoacross levels of detail or scale, respectively. Using topology as ascale-free perspective on describing processes, thought-provokingimpulses for new generations of data modeling standards like IFC andCityGML are to be given. Finally, the practicability of the developpedconcepts and software are to be demonstrated on a typical processlike the heat propagation within an integrated 3D city and buildingmodel.
