Practical Aspects: Industrial Implementation and Limitations in a Multi-criteria Context

Résumé

If the consideration of a purely economic criterion can be the optimal solution for a simple and well-known system, in practice, things are rarely as easy as a result of interactions with other systems. This is particularly the case for any complex industrial system.To illustrate this, we can take the example of optimizing a system of waterworks in a city: this system includes elements (pipes) of different ages and different types depending on the development of the city and neighborhoods, different loads (low or high road traffic), and a different environment (more or less aggressive soil in the case of metallic pipes for example), to illustrate only a few parameters among many others. The economic optimization of the maintenance of such a system is theoretically possible, provided sufficient information is available. Such information concerns the physical behavior, economic valuation, the failure rate or the kinetics of degradation by the factors mentioned above. However, this system also interacts with other systems in the city – sewage, electricity, and gas systems for example – which theoretically have their own optimal maintenance frequency.
