Cost benefit analysis observations
The counting solutions, despite requiring minimal design and planning time, pose a challenge due to their lower real-life accuracy. This necessitates frequent manual space count adjustments and correction of the PGS count, thereby escalating operational costs due to continuous staff involvement. In high-utilization facilities, the limited value generated by these counting systems substantially diminishes the final “Solution Value” score compared to per-space systems.
The wired ultrasonic solution with overhead per-space lights falls short of being an optimal choice. This is attributed to the highest solution costs, longest installation times, substantial design and planning time, and hefty additional costs for any post-installation modifications compared to other options. This collectively diminishes the overall “Solution Value” for wired ultrasonic solution with overhead lights.
In contrast, the per-space wireless PGS with Entrance and Directional DMS emerge as the most valuable solutions for this specific facility. In comparison to counting systems, these systems excel due to the lack of necessity for manual resets, given the high-utilization of the facility. When matched against wired per-space systems, the cost-effectiveness and shorter installation times of per-space wireless PGS and directional DMS provide a competitive edge.
