VBA Function to Randomly Assign Customers to Staff

Overview

This function will randomly assign a total of 4565 customers from "Sheet1" to 10 staff members listed in "Sheet2". Customers will be distributed as evenly as possible, and any remaining customers will be recorded as a "shortage" in column B of "Sheet2".

Code Implementation

Sub AssignCustomersToStaff()
    ' This subroutine assigns a total of 4565 customers from Sheet1 to 10 staff members listed in Sheet2.

    Dim totalCustomers As Long
    Dim numStaff As Long
    Dim customersPerStaff As Long
    Dim remainingCustomers As Long
    Dim i As Long
    Dim staffBaseRange As Range
    Dim staffCount As Long

    ' Define the total number of customers
    totalCustomers = 4565
    ' Define the number of staff
    numStaff = 10

    ' Calculate customers per staff and remaining customers
    customersPerStaff = totalCustomers \ numStaff
    remainingCustomers = totalCustomers Mod numStaff

    ' Set the range for the staff numbers in Sheet2
    Set staffBaseRange = ThisWorkbook.Sheets("Sheet2").Range("A1:A10")
    
    ' Loop through each staff member and assign customers
    For i = 1 To staffBaseRange.Rows.Count
        ' Assign customers equally to staff
        staffBaseRange.Cells(i, 1).Value = customersPerStaff
        
        ' Assign any remaining customers to the first few staff members
        If i <= remainingCustomers Then
            staffBaseRange.Cells(i, 1).Value = staffBaseRange.Cells(i, 1).Value + 1
        End If
    Next i
    
    ' Log shortage for each staff member
    For i = 1 To numStaff
        ' Calculate shortage for each staff member
        ThisWorkbook.Sheets("Sheet2").Cells(i, 2).Value = customersPerStaff - staffBaseRange.Cells(i, 1).Value
    Next i
End Sub

Explanation of Code

• Imports: In VBA, there are no explicit import statements like other programming languages. The built-in libraries are used directly.
• Parameters:
  • totalCustomers: Set to 4565.
  • numStaff: Set to 10, representing the number of staff members.
• Logic:
  • The function calculates the base number of customers each staff member will get and the remaining customers.
  • A loop iterates over each staff member, assigning customers evenly and distributing any remainder.
  • A separate loop calculates the shortage for each staff in column B of "Sheet2".

Input Validation

• The code assumes "Sheet2" has exactly 10 staff entries in range A1:A10. Additional checks can be added as needed for real-world applications.

Usage Example

To run this function, follow these steps:

1. Open Excel and press ALT + F11 to open the VBA editor.
2. Insert a new module (Insert > Module).
3. Copy and paste the provided code into the module.
4. Close the editor.
5. Run the AssignCustomersToStaff subroutine from the Macros menu (Developer > Macros).
