Global optimization is a feature that allows rescheduling multiple service appointments at once based on predefined criteria such as emergency priority, travel time, or skills[194]. Global optimization would allow Universal Containers to realign available resources with open work by running an optimization job that prioritizes emergency work and assigns it to the best available resources[195]. Resource Schedule Optimization is a feature that allows scheduling service appointments for individual resources based on their availability and preferences[196]. Resource Schedule Optimization would not allow Universal Containers to realign available resources with open work because it does not consider multiple resources or service appointments at once. Emergency scheduling is a feature that allows creating and assigning emergency service appointments to the best available resources[197]. Emergency scheduling would not allow Universal Containers to realign available resources with open work because it does not reschedule existing service appointments. Customer First scheduling is a feature that allows prioritizing customer preferences and satisfaction when scheduling service appointments[198]. Customer First scheduling would not allow Universal Containers to realign available resources with open work because it does not prioritize emergency work or reschedule existing service appointments.
