- the computer source code is for example a source code written in C ++ language.

- the data thus obtained relate in particular to information specific to the physical network infrastructure and business processes.
- Said data can be extracted from descriptive databases of the physical network infrastructure and business processes of the operator of said infrastructure.
- Said data such as the apparent age of a device or the impact of the environment on the aging of equipment, can come from measurement sensors installed on or near the equipment concerned.
- the apparent age can be evaluated, for certain types of equipment, by measuring a rate of gas dissolved in the oil, because this rate is directly a function of the state of aging and reliability of said equipment.

- the information relating to risk analysis typically relates to a risk analysis of the consequence / probability matrix type applied to the field of electrical networks and detailed in several technical brochures from CIGRE (International Committee of Large Electric Networks) -normalization of the electricity sector, in particular in the document entitled CIGRE Technical Brochure 309 - “Asset Management Systems and associated CIGRE activities” Working Group Cl.l (2006) and in the document entitled CIGRE Technical Brochure 597 " Asset risk management transfer - Progress in application "Working Group Cl.25 (2014).
- CIGRE International Committee of Large Electric Networks
- a risk analysis of the consequence / probability matrix type makes it possible to place on the same plane, for the calculation of the risks, elements as different as costs and environmental discharges for example, by means of a scale of gravity that is common to each key performance value defined a priori by the network manager.
- the gravity scale typically has 4 levels: Moderate, Serious, Severe, Catastrophic.
- key performance values Financial Impact, Quality of Service, Third Party Security, Public Image, Environment, Law and Regulation, Regulator Interference.
- the severity scale applied to each key performance value is then associated with a frequency scale of the dreaded events, to ultimately define a risk matrix reflecting the acceptability of the risk by the network manager. It is from this matrix that the information relating to the risk analysis can be determined.
- one or more of the following operations may also be implemented: • export of the list of necessary interventions for each week, in operational monitoring and operations supervision tools;
- a sixth step 160 the actions of the set of actions are executed in the physical network infrastructure.
- the operations carried out thus make it possible to maintain the equipment as it is, preventing it from deteriorating or refurbishing it.
- This refurbishment will modify the data describing the actual state of the equipment, which will affect a possible next implementation of the method according to the invention.
- One of the advantages of the method according to the invention is to allow the identification of early emergent phenomena, which would remain invisible by the implementation of known methods of the prior art.
- the method according to the invention makes it possible in particular to identify the effects of cascades where an event can produce a sequence of uncontrolled consequences in the infrastructure.
- the method according to the invention makes it possible in particular to predict the catastrophic evolutions of the infrastructure, because it makes it possible to take into account variations of the initial conditions, even when these are minimal, as well as the interactions of the different equipments.

- At least one aging measure specific to one of the components of said equipment At least one aging measure specific to one of the components of said equipment.
- At least one measure of the influence of the aging of said component on the other components of said equipment and on all of said equipment For example:
- the aging measurement specific to each component of an equipment can be obtained by means of a function representing a linear process, said function having as input parameter an environmental impact parameter, and as variable output a magnitude relative to the apparent age of said equipment (as opposed to the actual age of said equipment).
- the apparent age increases by an amount equal to the impact of the environment at each simulation step.
- the apparent age varies according to the apparent age of the second component, and to the role played by the second component: an inhibiting role of aging or an aging accelerating role .
- two rails having the same real age may have different apparent ages, especially if the density of cracks observed is different for each of the two rails.
- Two capacitors with the same true age may have different apparent ages, especially the average ambient temperatures observed differ in their respective environments.
- the deterioration for each equipment of the equipment set of the infrastructure, due to external causes is also determined by means of a stochastic process whose parameter is a rate.
- annual failure due to external causes The annual failure rate due to external causes is typically derived from historical data. In one embodiment, the annual failure rate is obtained from one or more databases, at the input of the instantiated model, or else configured by the user to test different scenarios.
- a planning P n for the year n is determined using the instantiated model, during a sub-step 210;
- a simulation of the aging of the equipment of the infrastructure, for the week s of the year A n is carried out of so as to obtain a list L s ⁇ n equipment may fail during the week s;
- the P n planning is updated depending in particular on the list L s ⁇ n equipment may fail during the week s, and according to the less a constraint, for example a constraint on human resources, and / or financial resources and / or equipment of the network - possible consignments -, and / or stocks; ;
- a simulation of the aging of the equipment of the infrastructure, for the week s of the year A n is performed again, taking into account the actions / previous operations relating in particular to the maintenance and / or renewal;
- a risk measure for the year A n is determined, using the planning P n and the results obtained for each week s of the year A n during simulations of aging infrastructure equipment.
- a measure relating to aging is determined.
- the method is described for an equipment E of the equipment set of the infrastructure.
- the equipment E comprises a component A coupled to a component B.
- this decomposition is not limiting. Indeed, the equipment under consideration may comprise a larger number of components.
- the steps described below are then repeated for each equipment of the set of equipment considered.
- an AOD death age is determined, for example by random selection, for each of the components of the equipment E, according to a distribution associated with the aging law of the standard profile of the device. equipment - usually Weibull type.
- the apparent age A (t + ⁇ ) of component A at time t + ⁇ and the apparent age B (t + ⁇ ) of component B at time t + ⁇ are determined at means of the following mathematical expressions:
- B 1 a mathematical function, describing the aging process of component B
- a (t) the value, at a time t, of the apparent age of component A
- ⁇ is a time step, expressed in years. Typically, ⁇ is chosen equal to 1/52, so that the time step corresponds substantially to the duration of a week, a year comprising on average 52 weeks. Thus, the period P expressed in years and between the year Ai and A N is spread over 52 x ⁇ weeks. A (t + ⁇ ) and B (t + ⁇ ) are then evaluated for all weeks of the year considered.
- a (t + At) A (t) + ⁇ ⁇ ⁇ ⁇
- the value of the parameter ⁇ ⁇ , respectively ⁇ ⁇ is generally chosen substantially equal to 1.
- the value of the parameter ⁇ ⁇ , ⁇ ⁇ respectively is chosen to be greater than 1.
- the value of the parameter ⁇ ⁇ , respectively ⁇ ⁇ is chosen to be less than 1.
- the usual values of ⁇ ⁇ and ⁇ ⁇ are discretized taking into account a number categories, all of these values can be obtained, in input, from databases accessible via a network.
- y (S (t)) corresponds to a nonlinear coupling function, which can be expressed by means of a sigmoid sigmoid function of Hill.
- the apparent age of component A is compared with the AOD A death age of equipment A. If the apparent age of component A is substantially greater than or equal to the age of AOD A dead A equipment A, equipment E is then considered likely to fail and is then added to the list L s ⁇ n .
- the initial apparent age and the set of aging simulation parameters are input.
- the planning P n can be updated by:
- sub-step 240 depending on the model instantiated and planning for that year n P n update, all the shares of P n s planning for the week of that year n can then be implemented and / or their effects taken into account.
- the aging of the equipment can be slowed down by maintenance actions applied, in particular by decreasing the apparent age of at least one of the components of the infratsructure equipment.
- the apparent age of the paint is reset to zero for the electric pylons during a painting type maintenance, or the apparent age of the oil is reduced following a degassing type maintenance of oleostatic lines. Repairing a rail reduces its apparent age. Therefore, the maintenance actions can be parameterized by a maintenance impact quantity, this parameter being obtained for example from databases and can be represented by a percentage, obtained by means notably of field maintenance records.
- a sub-step 250 overall indicators for the P period are determined based on the risk-related measures for each of the years A n of the P period.
- the following measures can also be determined: number of breakdowns, budget consumed, human resources used, number of operating conflicts, number of operations for each category - maintenance, renewal - carried out, etc.
- FIG. 3 representing the conceptual model, according to one embodiment, adapted to allow the representation of the different entities, links, interactions and action dynamics of a physical network infrastructure.
- the conceptual model is adapted to allow the representation of said network, substantially as a whole, by means of entity types, including types of following entities:
- At least one type of physical equipment for example high voltage and low voltage equipment - having a property relating to their degradation over time;
- At least one type of network constraint which is inherent in maintaining a certain level of customer power quality - for example, when an electrical work is cut off from the network for maintenance purposes, nearby service works must be able to withstand an additional supply of current passing through them; at least one type of human resource constraints, whether internal - for example, maintenance teams - or external - for example, supplier teams;
- budget constraints At least one type of budget constraint, eg budget constraints.
- network resilience is provided by the existence of multiple transport paths. .
- the network must be able to continue to operate in the event of a fortuitous breakdown, even if it is the subject of maintenance or investment operations. Consequently, the breaking of a path results in a transfer of the quantity transported on alternative paths. Whether it is an electric charge, a train or a quantity of gas, this load transfer is limited in quantity.
- electrical conductors can not exceed a certain electrical intensity, the railways have speed limits which in turn limit the number of trains possible on a single lane and finally the gas lines have a maximum pressure supported.
- This type of constraint is referred to as the logging constraint.
- the instantiated model can in particular take into account the constraints of recording, taking into account in particular the local neighborhood relations between equipments, modeled by an abstract entity called "Constraint Bag". Equipment that can not be jointly recorded belongs to the same bag of constraint.
- Constrained logging constraints can be parameterized, so that only a limited number of devices can be logged at a time.
- the conceptual model comprises all the types necessary for the representation of equipment and their interactions, in particular types relating to high voltage or low voltage equipment - transformers, circuit breakers, disconnectors, overhead lines, underground lines, pylons - and their interactions.
- the conceptual model is further adapted to take into account the dynamic interactions that exist between equipment, resources, and constraints. For example, accelerating the realization of a particular policy may lead to a postponement of other policies due to human resource constraints.
- the conceptual model is further adapted to allow the description of the planning of operations on the equipment of the physical network infrastructure, taking into account all the constraints. The business planning description is still suitable for automatically resolving resource conflicts.
- FIG. 2 showing a system of strategic planning and management of a set of equipment, said equipment being included in at least one physical network infrastructure.
- the strategic planning and management system is particularly adapted to implement the steps of the method for planning and managing the equipment of an infrastructure, described above.
- the system comprises a terminal module 10, a secure access module
- the terminal module 10 typically includes a user interface and may include a sub-module for using third-party applications.
- the terminal module 10 may in particular be provided with a central computing unit (more generally designated by the acronym “CPU” for “Central Processing Unit”) and with RAMs (more generally designated by the English acronym saxon “RAM” for “Random-Access Memory”).
- the terminal module 10 is coupled to the secure access module 20 to access the communication network 30, establish data links with the application module 40.
- the communication network 30 may be a local network and / or internet.
- the application module 40 typically comprises a processing device provided with a central computing unit (more generally designated by the acronym "CPU” for "Central Processing Unit") and of RAM (more generally designated by the English acronym "RAM” for "Random-Access Memory”).
- the application module comprises means for accessing the data storage module 70 via the communication network 60.
- the data storage module 70 comprises storage means 44, for example hard disks and / or disks. electronic systems, as well as a database management system.
- the simulation module is coupled to the application module via the communication network 30.
- the simulation module 50 comprises means for accessing the data storage module 70 via the communication network 60.
