The very simple features in Simio as the table and find process step were sufficient to model such complex problem. The purpose of this paper is to present the scheduling search algorithm modeled in Simio. NextYear: if the search happens to find the available spot in the following year again according to the preferences and rules. The objective is to keep the number of requests being destroyed in this sink to the minimum. The cells booked in the table (calendar) for the scheduled appointments will change from zero to one.īlocked: if the search algorithm fails to find a spot. Scheduled: if the search algorithm finds a spot according to the preferences and rules. There are 3 sinks that will destroy the generated requests after searching for an available spot: The processes will try to find an available spot following the predefined sets of preferences and rules. The search algorithm preferences and rules are modeled as processes in Simio. A fractional example of an open calendar of a room modeled as a table in Simio is shown below. Simio would search for an available spot for each generated request in the available rooms based on the preferred day and time. A “Dummy Call” as an entity is generated each day of the week that reads different linked tables to scan the preferred scheduled day and time. The simulation clock starts running and each day presents a mix of requested appointments out of 21 possible procedures based on the historical data. Modeling in SimioĪ snapshot of the model is shown in the figure below. Finally, there are some rules for which each type of the procedures is preferred to be scheduled in the available rooms where some cannot be scheduled except in specific rooms due to space constraints. In addition, the scheduled time is also studied to mimic the preferred time to book each type of the procedures. The statistical distributions are used to model the preference in how many days out the appointment is scheduled from the made date. The difference between the made and scheduled dates for each appointment type is studied and modeled in a statistical distribution for each day in the week. Therefore, the day in the calendar is divided in 15 minute time slots. The shortest appointment length is 15 minutes where the longest appointment length is 120 minutes. There are 21 different appointment types that can be scheduled in OPS with varied lengths. The fields provided with each data record are: made date, scheduled date, scheduled time, appointment type, and room booked. One-year of the procedures scheduled in the OPS suite was obtained. This white paper mainly discusses how Simio made this complicated exercise an easy and enjoyable technique to implement. The simulation model is used to study different scheduling modules like blocking certain rooms at specific times for some procedures. According to the annual demand achieved from the historical data, the simulation is run to book appointments in the available slots based on specific rules. The calendar (table) cells are filled with zero if the time slot is available or one if the time slot has been already reserved or blocked. There are 3 rooms in the OPS, hence, 1 calendar was built for each room. The calendar is represented by a table in Simio where the number of rows represents the days in the year and the number of columns represents the number of time slots in the day based on the shortest appointment. Simio was used to build an open 1-year calendar as the schedule of the OPS.
