Explanation
Operating Hours define when service resources are available for work and when customers can book appointments. The Time Slots for Appointment Booking setting determines how operating hours are divided into time slots that can be assigned to service appointments. The Maintenance Plan for the Account or the Due Date of the Service Appointment do not affect operating hours, but are used to generate and schedule recurring work orders.

Explanation
A Service Appointment can be shared by clicking Sharing on the record if manual sharing is enabled in Field Service settings[51]. Auto-generated scheduled Service Appointments will be shared with resources if automatic sharing is enabled in Field Service settings[52]. The Service Appointment's parent record can be shared with the assigned resource, but this would not affect the sharing of the Service Appointment itself.
Making the dispatcher the assigned resource on the Service Appointments would not make sense if they are not performing field service tasks. References:
