Three-Tiered Simulation Framework for Modeling Bridge Girders Fabrication Processes in a Steel Fabrication Shop

This paper describes a dynamic simulation application in modeling complex workflows of a bridge girder fabrication shop based on a three-tiered modeling framework. The objective of this framework is to produce straightforward, adaptive simulation models that can sufficiently represent essential operational details on the shop floor from the perspective of a shop superintendent. The resulting top-tier model allows the practitioner to define complex process logic in a way similar to developing activity-on-node network diagram for critical path scheduling. The middle tier is the core of the simulation where the entire shop operation logic, duration of each activity, and resource use constraints are encoded and mapped into a network diagram model. The bottom tier is essentially the simulation engine which efficiently schedules time events as per the logic and constraints defined in the middle tier and the top tier. The process of splicing two girders for trial assembly in a fabrication shop is illustrated in order to demonstrate the applicability of the proposed framework.
