Description

The Advanced Light Source Upgrade (ALS-U) project faces strict schedule requirements demanding rigorous planning of manufacturing assembly activities well in advance of assembly and installation. Delays of module components, and changes to the module tunnel installation sequence may significantly impact the module assembly (Prestaging) schedule for all 48 Storage Ring (SR) modules and therefore the installation of those modules during the 9-month SR removal and darktime installation period. To assess the adherence to schedule requirements, Prestaging developed a Visual Basic for Application coded planning tool to automate estimation of SR module assembly duration and resource needs. The tool 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 schedule and resource needs across 5 resource types for approximately 35 assembly tasks per module, generating duration estimates and resource profiles for SR module production. Functional testing has demonstrated the tool's capability to reduce planning time from approximately 4 hours of manual work per scenario-to-scenario processing to minutes while reducing inherent human error. With the model, Prestaging can quickly react to module component delays 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 use during the ALS-U module assembly phase.
