Once the decision to overbook workshop resources is made, it becomes essential to understand how to distribute booking hours effectively and automatically among workshop personnel. This is a critical step in ensuring the right overbooking workshop strategy is implemented without causing disruptions.

One of the best practices is to utilize resources based on skill level, with the most skilled person being only slightly overbooked.

How would one practically calculate that?

This is the topic I want to describe in my next article.

There are different algorithms available for overbooking. These algorithms include “proportional,” “sequential,” “progressive,” or “conditional” overbooking methods. There are many options to choose from, which means that one can write a book on this subject.

Based on personal experience, the ‘spread’ algorithm is a popular choice that best fits dealers’ demands. This method focuses on distributing booking hours among all resources, considering the skills each resource possesses. It ensures that less skilled resources are booked more, while more skilled individuals are booked less. As a result, more skilled mechanics are available, a crucial point in efficient service scheduling.

Does it seem complicated?

Well, let’s delve into the specifics, and I’ve created a practical example for you to follow.

Assuming the following scenario:

One workshop has four technicians with four different types of skills.

· Mechanic (MECH),

· Diagnostic (DIAG),

· Painting (PAINT),

· Body shop (BODY).

See example below:

Now, let’s get to how to distribute booking hours if, for example, 7 MECH Hours are booked for doing a service task, but the workshop lacks MECH available skills.

The spread overbooking algorithm takes into account a mathematical formula to determine the optimal overbooking amount.

Conclusion: Thanks to this automatic algorithm, John, the most experienced person, is now less overbooked than others.

As a result, some decimals can be seen, but it does not really matter. These numbers do not bother end-users but are crucial for dealer management systems or scheduling systems to manage overbooking effectively on a skills level.

I hope my article provided you with valuable insights. I am waiting to receive your feedback!
