Disaster Arrivals Weekly 2

This model object takes actual weekly arrivals summaries for past events and creates patterns of arrivals by day of week and hour of day. 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 are changed by using an attribute.

The user has control of how arrivals are distributed across the week by a simple spreadsheet interface. The user can define what pattern is used to spread entities across the hours of the day. These are predefined patterns AND can be changed by the user. A simple multiplying factor allows the user to copy data from past disasters and modify the amplitude to prepare for larger or smaller events.

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.
