This model object takes actual daily arrivals summaries from past events and creates patterns of arrivals by hour of day. It can be used to recreate events from the past, so you could check the effect of changes OR use a multiplying factor to modify past disasters and change the amplitude to prepare for larger or smaller events.

The object allows Arrivals to be processed for several divisions, center or departments in the same stream of arrivals separated by an attribute. Entity names and graphics could be changed by using an attribute.

The user can define what pattern is used to spread entities across the hours of the day. These are predefined patterns AND the patterns are changeable.

This model object can be used multiple times in the same model by saving the Excel file as a new name, and then linking a separate object to that new file. This means different disasters can have completely different patterns of arrivals.
