中文摘要：

针对目前工程施工资源配置面临的建模过程复杂、效率低等问题,本研究提出一种基于BIM模型数据标准IFC的资源配置离散事件仿真模型自动生成算法。本研究首先构建了基于IFC的进度资源信息模型,通过分析IFC模型与离散事件仿真模型的异同,实现前者向后者的自动转换。并将上述模型与模拟退火算法相结合,开发了模型转换及资源配置离散事件仿真分析软件,应用于实际工程,验证模型自动构建方法的可行性及正确性。结果表明,研究成果可提高仿真建模的速度与准确率,为管理人员快速准确的进度与资源配置、管控提供有力工具。

英文摘要：

To eliminate low effort and complicated model process needed in data modeling for resource allocation,a BIM-based approach to automatically generate discrete event simulation（ DES） model for resource allocation was proposed. Firstly,a model was established based on IFC to model schedule and resource information. Then,with comparison of IFC model and DES model,automatic conversion from the former to the latter was achieved. Finally,taking simulated annealing as the optimization module,a model generation and optimization application was developed for resource allocation,and was validated in a real project. Results show that automatic generation of DES model can reduce mistakes and avoid rework in resource allocation modeling, thus facilitating decision making in schedule and resource trade off.
