- Time \ Remaining Length of Stay Estimator
Difficulty Level
- Ease of Use: Moderate
- Ease of Modification: Moderate

- Update objects
- Copy the logic from the action logic of the Ward 1.
- Use this logic to replace the term a_Next_Time in the action logic of the “ward” in your model.
- For each “ward” a new variable needs to be added, v_LocTime2, v_LocTime3, etc.
- Replace the v_LocTime1, in the ward, with the newly created variable.
Note: At the start of the model: 1. How many entities will be in a “ward” are of the hospital? 2. How much remaining LOS with a patient have. Both of the items above are needed to accurately predict the behavior of the system.
- Review model:
- Run the model for an extended period. Several years so that a sufficient sample is collected.
- From the output report, export the variable data for v_LocTime# to Excel, and then open the Excel file from the location it was saved in.
- Remove the first 2 months of data (Use the appropriate time for your the ward).
- Analyze the Excel export to determine the “census” and “remaining LOS”
- Use Stat::Fit to create a distribution for be beginning census and remaining LOS.
- Copy the “values” left in the Excel file.
- Goto ProcessModel, open Stat::Fit (Tools \ Stat::Fit) and paste the copied data.
