本文提出了一种方法，它再现物流过程中的建筑工地与传统的物流模拟器。因此，在土建工程开始之前，可以测试和验证不同的物流策略。在开始的艺术状态有关的建设物流和模拟现场过程的发展。在这种情况下，不同的供应和仓库策略的建筑工地。该方法从系统负载生成、概念模型的建立和可重用模块的开发三个方面进行了阐述。为了生成系统负载，将建筑项目的CAD建筑模型数据导入数据库并进行编辑以进行仿真。材料纯部件是根据材料符合数量（件、m、t等）开发的，这与时间表的时间部分有关。在下一步中，零件被组合成区段，这是材料供应的基础。此外，在数据库中还加入了物流标准数据，以建立物流单位，如运输单位或装卸单位。开发概念性仿真模型是为了描述独立于具体项目的建筑工地的物流流程。问题是物流资源在不同战略下的生产力如何。为了建立计算机模拟模型，采用了面向单元的物流模拟器，并开发了新的通用单元来描述现场资源。这些单位的普遍性对于将它们用于不同的项目很重要。通过一个示例项目，对不同的供应和仓储策略进行了测试和评估。它示出，系统如何对约束的变化做出反应，以及吞吐量或等待时间等关键数字如何变化。最后对全文进行了总结，得出了具有普遍意义的结论.在展望中，提出了进一步研究的需求，并对物流站点的进一步策略进行了系统的分析。
In this paper a method is presented, which reproduces logistics processes on construction sites with a conventional material flow simulator. So it is possible to test and verify different logistics strategies before a civil work starts. In the beginning the state of the art concerning the development of construction logistics and simulation of site processes is given. In this context different supply and warehouse strategies for construction sites are presented. The method is structured in system load generation, building a conceptional model and development of reusable modules. To generate the system load the data of the CAD building model of the construction project was imported into a database and edited for simulation. Material-pure Parts were developed with material conform quantities (piece,m, t, etc.), which were connected with the time component of the timetable. In the next step the parts were composed to sections, which is the basis of the material supply. Furthermore in the database logistics standing data were put in to build logistics unities as transport or handling unities. The conceptional Simulation-Model was developed to describe logistics processes on construction sites independent to concrete projects. The question was how productive the logistics resources are in relation to different strategies. To build the computer simulation model a unit orientated material flow simulator was used and new universal units were developed to describe the site resources. The universality of the units was important to use them for different projects. With an example project different supply and warehousing strategies were tested and evaluated. It is shown, how the system reacts on variation of constrains and how the key figures like throughput or waiting times shift. In the end a summary is given and universal conclusions are made. In the outlook the research demand is given concerning further units and a systematically analysis of further logistics site strategies.
