Comparative Analysis of Two Capacity Restraint Assignment Models Used in Texas (1153-5)

As part of the investigation to improve the assignment models, a comparative analysis of the Texas Capacity Restraint Procedure and the Joint Model Capacity Restraint Procedure was undertaken. The basic goal of these analyses was to attempt to objectively compare the two procedures, evaluate how the results of the two procedures differ, and identify (if possible) the primary sources of any differences that may be observed in their ability to replicate observed improvements to one or both procedures.|The comparative analyses found that both models reasonably replicated observed counts and neither model emerged as clearly superior. Several enhancements were recommended for the Texas Model. These included implementation of an equilibrium option and implementation of an option for multiple user-specific impedance adjustment relationships.
