We can perform employee scheduling algorithm in Excel using the in-built Solver feature. This algorithm is particularly handy when it comes to efficient workforce management for an organization.
We will perform an employee scheduling algorithm for a hospital. First, we have to create a dataset. Then we will create a result outline and insert a suitable formula. And, lastly, we will carry out the analysis with the Solver feature.
Step 1: Necessary Assumptions for Employee Scheduling Algorithm
For conducting the employee scheduling Algorithm, we must make some assumptions.
- Let’s take a dataset of five nurses and the number of hours they are willing to work each day. Also, they might not work every day.
- In row number 10, we have put the minimum number of nurses required for each day.
- Now, let’s modify this dataset.
- Create a data table of nurses and set 0 in every cell like the image below.
- This hospital we are working with provides a minimum of two holidays for their employees.
- Add a column and a row like the below image.
- In Column J we will find the total number of days each employee has to work in a week.
- And, Row 17 for the number of employees required each day.
- For this analysis, we also have to insert an Objective box to show the total number of employees working hours in a week.

Step 2: Using SUM AND SUMPRODUCT Functions for Employee Scheduling Algorithm
Let’s see them.
We want to find out the maximum possible working hours of the employees in a week.
- So, write the following formula in K5 and press ENTER.
- C12:I16 = array1
- C5:I9 = array2
Upon entering the formula, the cell should give 0.
- Now we will use the SUM formula so that we can find the number of days each employee has to work in a week.
- So, write the following formula in J12 and press Enter.
C12:I12 = Data Range
- Then Hold and Drag the J12 cell downward to copy this formula for all the cells.
- Again, we have to set SUM formula in Row 17 so that we can find the number of nurses working each day.
- So, write the following formula in C17 and press ENTER.
C12:C16 = Data Range
- Then Hold and Drag the C17 rightward to copy the formula in all the cells.
Thus, our dataset is ready for analysis.

Step 3: Applying the Solver Feature in Excel
Now let’s analyze the dataset with the in-built Solver feature.
- First, go to the Data ribbon and click on the Solver icon.
So, a Solver Parameters window will open.
- Now we have to set these solver parameters which is K5 in this case.
- Set the Objective cell in the Set Objective box.
- Keep the To section Max.
- Insert the data array $C$12:$I$16 in the By Changing Variable Cells box.
- Also, we have to set three constraints.
- So, click on Add.
- This constraint is for finding the employee’s working days. We want to know whether an employee works on a given day or not. We want to get the value in binary. 1 will mean they have to work and 0 will mean their holiday.
- So set the Cell Reference to $C$12:$I$16, choose the bin (binary) option from the adjacent box, and press OK.
- The constraint will appear in the Subject to the Constraints box.
- Now, click on Add for another constraint.
- This constraint is for the number of employees required each day which will be equal to the data range C10:I10.
- So, set the data range $C$17:$I$17 in the Cell Reference box.
- Then choose the = (equal) sign in the adjacent box.
- And, set $C$10:$I$10 in the Constraint box and press OK.
- The new constraint will show up in the box.
- Now, we will add the last constraint.
- Click on the Add option.
- This constraint is for setting the maximum working days for each employee in a week.
- So set the data range $J$12:$J$16 in the Cell Reference box.
- Choose the < = (less or equal) sign in the adjacent box
- And lastly set the Constraint to 5 and press OK.
- Thus, we have set all the constraints.
- Now, choose the Simplex LP option from the Select a Solving Method box and click on the Solve button.
- Doing so, the Solver Results window will open.
- Make sure the Keep Solver Solution is active and press OK.
- Therefore, the solver will give you results.
- The Objective Cell indicates the number of working hours that the organization can get out of its employees.
- The data range C12:I16 shows the working days of each employee in a binary form.
- The data range J12:J16 shows the number of working days in a week for each employee.
- The data range C17:I17 shows the number of nurses assigned on each day.
