ANALYSIS AND AUTOMATION OF SEQUENCING AND PLANNING FUNCTIONS ON INDUSTRIAL CONSTRUCTION PROJECTS

工业建筑运营严重依赖于制造和模块化技术。然而，他们面临着许多挑战，这些挑战降低了这种建设方法的好处。工业建筑设施的要素具有独特的设计和配置，需要在制造设施中进行定制。与传统制造不同，这些元素的制造顺序各不相同。这些元件还需要在模块化单元中预先组装，并按不同项目的顺序在现场安装。材料交付、资源可获得性和设计更改的变异性和不确定性要求制造、组装和现场安装操作的计划和排序必须高度适应，以保持最佳性能。由于这些操作的复杂性和在执行过程中动态变化的大量因素，在这些操作的计划和控制中人工输入是基本的。然而，人工计划和排序选择的最佳性和对性能的影响还没有得到定量评估，这些选择自动化的潜力也没有得到充分的研究。

Industrial construction operations rely heavily on fabrication and modular techniques. However, they face many challenges that reduce the benefits of this construction approach. Elements of an industrial construction facility have unique designs and configurations and need to be custom built in fabrication facilities. Unlike traditional manufacturing, the fabrication sequence varies among these elements. The elements also need to be pre-assembled in modular units and installed on site in sequences that vary from one project to another. Variability and uncertainty in material delivery, resource availability and design changes necessitate that the planning and sequencing of fabrication, assembly and site installation operations be highly adaptive to maintain optimum performance. Manual human input in the planning and control of these operations is fundamental, due to their complexity and the large number of factors that change dynamically during execution. However, the optimality and effect of manual planning and sequencing choices on performance has not been assessed quantitatively, and the potential of automating these choices has not been sufficiently investigated.
