Case study
Fluxys – Tenders Evaluation and Selection
Challenge
Fluxys is using fiber optic cables in order to track gas usage data. The company had to buy new cables and, therefore, made a call for tenders for the purchase of hundreds of miles of cables of different capacities and characteristics. While the price was obviously considered, other cable characteristics were also taken in to account including its mechanical and optical performance.
Actions
After establishing guidelines and objectives, Fluxys decided to complement its methodology by using the D-Sight software to compare the different offers.
Results
D-Sight allowed Fluxys to conduct a deep evaluation process while easily taking into account all necessary criteria for a proper product assessment. Hence, the time spent in multi-criteria comparison was considerably shorter, resulting in a faster tender evaluation process, which saved considerable time to Fluxys’ employees during this project phase.
The challenge
Fluxys is the independent operator of both the natural gas transmission grid and storage infrastructure in Belgium. The company also operates the Zeebrugge LNG terminal. Fluxys has developed its infrastructure into the veritable cross roads for international gas flows in North-Western Europe.
In order to manage all gas usage communications – e.g. measure, remote control, etc –,Fluxys makes extensive use of fiber optic cables. As it had to renew part of its optical network, Fluxys needed to buy hundreds of miles of new cables of various capacities, ranging from 8 to144 fibers per cable.
To evaluate the offers, Fluxys brought together staff members from different functional teams to combine qualitative judgments and quantitative data. During those meetings, they had to:
• Take into account non-financial criteria such as mechanical and optical characteristics
• Achieve good communication between the stakeholders
• Promote a better offer selection process via fast and binding decision-making
• Ensure the selection of the best provider
The actions
Given the increasing number of international tenders under management, Fluxys resolved to standardize the way offers were being compared. This is particularly important when technical requirements are part of the equation and multiple criteria need to be considered in order to evaluate products or services properly. In addition, Fluxys is generating more than 500 calls for tenders a year and it is therefore important for it to streamline its processes.
The method originally used by Fluxys to evaluate the offers consisted in a weighted sum implemented in an Excel sheet. As the procurement department was in contact with a research unit of the University of Brussels, active in the field of multi-criteria decision aid, Fluxys decided to test D-Sight. This initiative was aimed at providing a deeper and faster analysis of the received offers data.
During the evaluation phase, two Fluxys staff members worked on this call for tenders: a buyer and a telecom engineer. The buyer was responsible for all the procurement aspects as well as the legal and financial provider evaluation. On its part, the engineer was responsible for evaluating all the technical aspects of the different products.
The results
By using D-Sight, the team was able to conduct a faster offer evaluation process. While saving time, D-Sight gave them the possibility to immediately have a global idea on what the providers offered. Further more, as the team held progress meetings, the interaction between the buyer and the engineer was improved significantly. Indeed, the interactive interface of D-Sight allows the stakeholder to easily understand the results.
The numerous tools available with in D-Sight allow for a deeper offer comparison. By empowering the users to perform sensitivity analysis, the stakeholders are comforted in their choices and can easily and rigorously justify them. Inaddition, D-Sight provides a results export feature for simple report creation.

Traditionally, weighted sum is used in an Excel sheet. By using D-Sight and its advanced methodology, you can specify on what basis the offers have to be compared, for each evaluation criterion. All the visual tools allow you to perform a deep and fast analysis in which you can easily interact with your teammates. Finally, the sensitivity analysis tools give you the opportunity to make more confident and solidly substantiated decisions.
