Description
The Advanced Light Source Upgrade (ALS-U) project faces strict schedule requirements demanding rigorous planning of prestaging activities well ahead of time. Prestaging is the manufacturing group responsible for ALS-U module assembly (prestaging can also refer to the act of module assembly). Delays of module components, and changes to the module delivery sequence may significantly impact the prestaging schedule for all 48 Storage Ring (SR) modules. Prestaging developed a planning tool based on Visual Basic for Applications to automate estimation of SR module assembly duration and resource needs. The methodology is based on bottom-up task sequencing where individual assembly tasks are laid out in succession with adjustments made for resource constraints and equipment conflicts. The model processes duration and resource needs across 5 resource types for approximately 35 assembly tasks per module, generating duration estimates and resource profiles for SR module assembly. Functional testing has demonstrated the tool's capability to reduce planning time from approximately 4 hours of manual work per scenario to scenario processing within minutes while eliminating inherent human error risks. With the model Prestaging can quickly react to changes ensuring assembly planning is optimized within the constraints of the project. This contribution describes the model development methodology, functional testing results, and applications for future changes during the ALS-U prestaging phase.
