Fatigue Risk Management System



A FRMS is a system driven by data of continuous monitoring of fatigue risk in workers. It is based in scientific knowledge and operational experience, taking into account preventive and reactive elements, and it seeks to reassure that the staff of a company is operating at proper alert levels.


Accidents occur when different areas of danger align and an event simply occur. In many cases, shifts structure does not allow us to eliminate fatigue, but administrate it"

Implementation in heavy duty transportation


Thanks to safety areas functions, scientific principles and our own studies, we are capable to implement a FRMS in transport operations, specially in the ones with 24/7 shifts. To make it possible, we focus on three safety areas, which are made of:

Sleep opportunity

This safety area is the most preventive one and is related to the sleep opportunity which a driver has depending on his/hers shifts structure. The goal is to reduce risk by managing shifts in advance.

Compliance: Supervise regulations compliance in your operation. Avoid work excess in your drivers and manage fatigue generation. SEE MORE


Shifts Biocompatibility: Analyze shifts composition and risk in function of workings hours, rotations, night trips and sleep pressure. SEE MORE

Obtained sleep

Fatigue is directly connected to the amount and quality of dream, that is why is necessary to correctly understand how effective is sleep opportunity of workers. This area is focused in estimating and measuring sleep. This layer considers the next module:

Training: Teach your drivers about fatigue and sleep science so they can be more aware about the dangers of shifts work. With training, companies can reduce their costs per accidents and it can be done with E-Learning and Train The Trainer programs. SEE MORE

Alert Level

Is the last safety area and its objetive is to react against drivers risk. Managing at this point is essential because each action can be decisive at the time of a severe accident. This area is made up of two modules:

Cumulative Fatigue Level (CFL): Analyze risk by hour for the next working hours . SEE MORE



Microsleep Events (MSE): Integrated with somnolence sensors, which not only allows to check events on platform but also to manage the risk and calibrate our Fatigue Model.



Our different modules were created to reduce fatigue risk and we are proud to have a software which consolidates all data allowing our clients to manage risk. Also, our experience has teach us that each client is unique, giving us new approaches to calibrate our fatigue models. Gauss Control team is continuosly doing a big effort to guide our clients implementing a FRMS without affecting productivity and reducing incidents rates.

We are proud to say that we have managed to improve accident indicators in our clients in a one year period.
