Schedule your workforce to meet labor demands (example) The following example demonstrates how you can use Solver to calculate staffing requirements. This is a much more powerful Solver with no limitations in size. You can use Excel's Solver add-in to create a staffing schedule based on those requirements.

This model is free and integrates nicely with Excel 2003 - 2010. If you build a bigger model you may have problem with the Excel solver as this is limited in size.Īnother option is to Google for the OpenSolver build by the University of Auckland N.Z. If in the other hand if shift started at 0:00 I needed 16 nurses and lost 174 hrs.Īs this is a simple solver problem the "Simplex LP" should be what you need. Result starting at 07:00 I needed 15 nurses and "lost" 126 hrs, starting at 06:00 gave the same result i.e. To use any of the six worksheets Product Mix, Shipping Routes, Staff Scheduling, Maximizing Income, Portfolio of Securities, and Engineering Design open the workbook, switch to the worksheet you want to use, and then click Solver in the Analysis group on the Data tab. This is why I decided to start the shift cycle at 07:00. Looking at the OP's model you will see that the demand for staff is 24 at 0:00 and then drops down 12 at 05:00 and starts increasing at 07:00 and reach the highest value 34 at 19:00 and then it drops steadily from 21:00 to midnight.Īs I assumed a nurse works 12 hrs, a nurse staring at 0:00 will then work until 12:00 so I could not take advantage of the slack hrs between 05:00 to 07:00. As my understanding of the Evolutionary engine is rather sketchy I can offer no better explanation.

This was just to model the solver setup as I was testing my solution with the three different solver engines.Īs the algorithm for Solver is written by Frontline Systems and probably modified a bit by Microsoft I don't know what this algorithm look like and as you found out it's password protected.Īs to getting different results when you run the Evolutionary engine, well that could depend a bit on the starting point. Leave one blank column after the last variable and label. Label the rows down the left hand side in column 1. Put the objective function coefficients into a row with at least 2 blank rows above it with the constraint coefficients below. You can ignore the VBA found in my uploaded model, you can just run Solver as a standalone without any macro. Solving Linear Programs in Excel Step by step instructions to put LP into Excel 1) Put the problem into Excel. Choose the > (greater than or equal to) sign from drop down menu. It will open the dialogue box as shown in Cell reference select the cell E8. To add the constraints, Click on Add in as shown in Image above. Example 1 considers a simple situation of scheduling a workshop. Enjoyed this content & want to support my channel You can get the spreadsheet I build in the video or buy me a coffee Links below:Buy me a coffee: https://. 2 Demand Function Example Given data representing demand at an airport (D(t)) we would like to derive the best nonlinear model to fit the data to a model of. Now in By changing cell variables select the decision variables C4 and D4. In response to a PM to me I've added some new comments to this thread: Application of the above procedure, using excel solver, is illustrated using two examples.
