 the summary of the methods in the police section. Presentation is provided by myself, but I'm not sure if they've needed me to do that. Elizabeth is also there. I'm from the people at Sebastro for that. So I was there to provide the summary of the activities we embarked on as part of the group to introduce, in a better way, what was the stroke. The way it's gained what was the actual pain and motivation of this working group, which have to do with the combination and the combination of data or the algorithm of tools that can be used for analyzing the value of information. It was, of course, a work of hardware groups to define what the value of information is, but we found ourselves, in fact, doing it by specifying the difference diagram that I showed you on which we have based all the framework of the value of information, at least as we understand it, and in an effort to introduce something like a vocabulary, something that will allow us to discuss on the same terms. So the concept of the value of information, I think it was already explained by a legal power that is rather a new concept and one that seems to cause a confusion, and I will agree with him. I remember being part of a work group meeting in Munich where we had intense disagreements as to the process of the value of information, coming from different experts in structural health monitoring or in the library analysis, but the important thing is that in the end, we could agree on the main objectives. So what I mentioned before, that we introduced as part of our working group the influence diagram, which supports the modeling process for the method. The objectives that we tried to address, first of all, gathering these tools along is a large task, also because they are defined in different contexts, and you can find them available as tools for library analysis, for uncertainty quantification, for a number of different projects, but never brought together in the context of the value of information that is really a more expensive cycle. The main objective of our group, identifying, developing, and critically overviewing methods and tools required for the VLI context. And finally, also the standardization of the vocabulary, which of course is a rather challenging task, and I'm not sure if we can say we have completed, but we're glad to have started working on it. So the achievements, and I will present them one by one in the presentation that folios are essentially defined within these objectives that we set out to address. The first time it has to do with the aggregation of past sheets that really contributed to the identification process of the methods that are involved in the value of information framework. And let me start actually by this. So as mentioned, this is the influence diagram on which we base the vocabulary we're trying to develop and also the methods that we will consider as spinning for this task. And number of past sheets now being submitted throughout the course of the action. And so here I will mention some of these that basically are part of this diagram. But before I go, I'll use a few words of the description of this conceptual line. The reason why I'm attaching this is in 2016 which a lot of the work was done for the development of the 10 grades was based on. And so I'll be just a few slides. I know that people are referring to the past sheets and I was a nominee of the technical company for existence, but so with this graph, we have a sense of the links between the system and the reality that we have, that they're monitoring the data and the actions that can emerge. The consequence of this is going to be data and the effect of respectful performance with associated benefits in this is just to show you how we can evaluate some of the course of the development of the information of the sort of algorithmic training if we have access to both the consequences for not having the data from the sort of data monitoring compared to the consequences of having it. And then by comparing these two values, just to put the values we get, the value of the sort of algorithmic training. Now, in order to develop this comparison the difference diagram that holds is here is basically shows the different components that are needed in order to build the system model. So just a reminder about how to sort from there but we'll make a short program for me. So with the ground rules, we have the parameters which are the insertion, and so in the random variables. The square nodes are the decisions that can be taken during the lifetime structure and the diagonal nodes are the consequences costs each team associated with state of the system or the cost of the action. And then here we get identified in the box which is both the links that most people present together, let's say the quantity of the system to consider. So the links between the madness on the system, structural condition, and then that join together with the structural performance. Then we have a cost model to see if we're the performance of the system, which has to be, this has to be defined. Then there is the very important parts which is the identification of indicators which actually represents, will represents the system and link the different characteristics together in order to have something that's a bit more, that's a bit less, let's say complex than the amount of course. So you can have journey in a crack model, for instance, for fatigue, or a little frequency, et cetera, and then this is still linked to the structural performance and then back to risk. Here we have the log about choice of the structural definition strategy, which should be able to stay constant over time and will be decided at the beginning. And this, of course, includes also no structural performance. So this is where we have the comparison is being made available by tracing the number of structural performance in the system. Here we have the lighting models. We get basically the entrance appropriation from observations to indicators, and then to open system part of the time earlier. And here we have maintenance actions with associated costs and their effects on the system. Finally, this is the work, this is the, this is what signifies it's sequential decision process and actually the connection to the data observed. So, within the couple of three, there was also a package of, let's say, test package of the bias that were developed on the gene, which are, we say, it's not very good. It was already mentioned that they made two different parts of the ASHM process, the condition of the structural system and also interventions. This is the color of the indicators that you see. And, of course, in others, the processes and usually that's where you find the methods and tools. Now, in the fact sheets, we are having, in October, represented the course that fall in this category, the main categories of the entrance diagram. Perhaps one of the most critical ones being the one of the indicators, because really what will decide our judgment about what the system is, the indication of the condition. It's really the part that comes straight forward out of the structural health monitoring. So, here we have the fact sheets on extraction of vibration-based damage indicators and a demonstrator on the z-point report which, by different authors, my opinion, in the first one, let the fact sheet and then it will render for the second case. Additionally, we have the situation where we have members in the post-action that access to different ways of collecting information by monitoring. So, from the group of Aparahumia University of Orto, we have a fact sheet on a digital repository of data that is available for structural health monitoring. We're talking about the collection from their deployments on a number of bridges throughout Ortoville as well as some cases of the window-wide facilities. On the level of new, let's say, emergency-sensing technologies we'll have the work of a satellite factory on wired sensors that are used for on the road and food bridge. And then we also have the fact sheet by us on the case of ship-off structures because, of course, we're talking about engineering systems so not necessarily what typically one would refer to as a structure. Closer now to the point of methods that have to do with this influence diagram, we have a fact sheet on reliability update based on monitoring quantities and by Xenorea. And we also have the work of Papademitri on Beijing Analysis Methods directly related to this action for this process nine here, which leads to observations of compromising and to the actions over about the date. Now, for the actual decision-support procedure, how do we decide on taking these actions? We have to go a step ahead from updating and that's where we have the fact sheets by myself and from Mr. Papademitri and external operator of the action on partially observable work-up decision processes, one of many options one can use for this decision-support in the case of uncertainties as well as the fact sheet on identification and prediction, model classification this could also be kind of drop-chaining practice perhaps a commitment that is promoted as a decision-support for engineering operators based on the formulation of specific let's say boundary to most foreign decisions. So other than the fact sheets that we have gathered and find available on the web page of the action there is also the working with free related conference papers with the name of dissemination that contributes to the development of new methods so there you can find information that is perhaps closer to a state of the art college or forth from research and these you can also find on the web page of the action in the relevant catalog for scientific papers I just get some of these here and of course find a complete list posted I want to also invite the ones that have made disseminated papers that are only in this category to contact Sebastian because this could be this list is updated continually and then finally I come to some more practical achievements of this working group or at least what we consider the first one has typically the establishment for the collection of this library a software database on value of information and uncertainty quantification when this is a document that is available for all members of the action through the repository of the action so you will find it in the working group free folder what essentially this does is collects in one case some documents that are available to identify that could be used in different components of the process of the value of information diagram I won't go through this extensively because it was presented also in common but I will show you an example of the use of such a tool and actually not me this will be let's see here this will be by a little bit on this the use of G which the software that can be used as a modeler or perhaps the user interface or vision network software maybe we can use this tool to bridge the normal value of the user following the structure of the input center that you saw right here with those two examples that are available to them so I can probably see it but if you go around what sites here are the PGOs of the A you can find the other signature materials for example cases of the sequential student meeting and the evaluation of the value of information for example very basic example of the structural function system but it's using the interface of G by building them so we have two time steps and in this case we have first the basically the system that that's for which you can collect the data the data and this data is the problem, the light in the problem like a set is defined by both the link between being paid and the data but also by the choice of the essential technology and this will lead to the action particularly the maintenance action and they will then impact the structural condition and the consequences on the benefits and risks and basically G allows you to do a variation analysis of this network in the sequential process and particularly about what we have if you have a similar system you can actually get the value that you really need for so like if you can download two examples one is two time steps and another one is G like I said is quite simple to use for but and to let's say introduce future with your company as well but of course we need to do much longer analysis when you want to go to specific program projects this list is now available in the social open for which means that you have tools which you would like to see included or your development tools that you would like to see posted you can just come back to us and we will make sure that these are included in the options the easy now is how do we move on from the simple concept of this library to the action generation in the testing of the tools there is working group four and working group four is on the playstyles that we wanted to do or a reference example where the different methods can be verified and possibly even combined so that the hybrid can not occur so for this reason we established what we call the benchmark of the action that we for verification which is nothing more than a simple example it is a structural system for which we provide a modeler so we provide a tool online which can do the simulation it is a tool span B essentially which is simulated under bending using gain elements and for which we provide good scenarios of different deterioration effects the purpose of the benchmark is to use it as a simulation scenario that you would like to enforce the value of information let me show you some examples of what the benchmark right now can do and hopefully you will give me feedback on what you would like it to do so we have prepared essentially a Python code which is open source for those interested but also executable for those that do not care to go into the code that you can run and get the analysis of this two span beam essentially the input properties are defined by the user so it is the material, the thickness and the operational loads that could be dynamic there is also environmental variables such as pen texture that define the properties of the materials and also the deterioration agents such as corrosion corrosion or you can also have cracking in a very simple manner as the water reduction of the thickness of the gain elements and then you have the output which is in the form of a model analysis information on acceleration strains and any other property you want extracted from the typical Python model so here is how it works actually let me show you how you call it just fully I don't run it from the executable I run it from the Python script but that doesn't make any difference you would just call a program to do this if I address on running you get the very simple interface where you have the different scenarios for this beam in that scenario you choose one of these two scenarios and you submit the job requesting a model analysis a specific temperature and then some specific variables for deterioration that I will explain you can basically have the output which you can use in any way you wish for any kind of analysis whether it be liability, fabric assessment and so forth so it should be an example of the low shapes that you would get in the case where you have one that is concentrated here on the support and you would get the first some low shapes depending on what you would specify it's really a simple model that you can serve as a common simulator what are the functionalities now what can you specify there that is useful for such a model these are some of the natural scenarios so if you have a model of a model in different sections you would be able to specify variables and the numbers to be assumed because perhaps you are relying on the importance of an identification or an infection problem how much the essential numbers is and then you can also have some scenarios in that sense you can specify the numbers your inputs on the use values one thought without this also includes humidity and perhaps some custom laws of the evolution of the elastic programs with respect to this energy for now in the in the beta version now we only have a few specified variables that this can change to put the rest of the variables in the case additionally we have another such deterioration that has to do with corrosion and here we assume corrosion it's as simple as that because of the elements and what you can specify is basically the corrosion wastage which plays on great great fine curves that we have used from the literature who take essentially what will be the thickness in fact is enough to impose on the fine element now for the software this will be the model analysis case for you to have a 90 string analysis which will give you outputs in the form of acceleration here or Spain what we said we would have of course any type of active force that you would stimulate at the end you can use this for all sorts of analysis one of the options for us is to check the deterioration by looking at the the deterioration in the frequencies but also the effect of the deterioration on mold shapes which could be a a totalization some thermo-calculation or the thing of using it in the context of the data so you would have another code that is used in the simulator with a little attention or even the decision support which I showed before so what was the point of this we were faced with something that is a common reference a common variation we would like to collect for you a lot of the additional features and we will leave you to work as testers so in essentially trying to use your tools to demonstrate on this ledger here I can invite some volunteers to see if they could use it to make more of the data by using a computer for modelization for page and app and I think other applications have to make suggestions and just in a commitment work for some of you can say what was possible what would you think of demonstrating on this is there something you could use for giving your tools the same so I'm going to add I'm going to take the store as a commitment by the way mostly from the web page and maybe there should be any way you can use these users to test it and send us a digital model with their methods on so then there could be a page where we can demonstrate and so on okay I already mentioned this learn this is to be a common reference for everyone but for sure it helps it's a piece of first step so in that sense I'm happy to be doing so so thank you for your questions really many questions and now for the last question which is really useful I think thank you it's a great thing because we're doing it for the temperature it may be useful to allow us to include the interest of the temperature on the problem conditions and to see if we can solve it if it's possible I think it's possible if it's possible no it's completely possible just out of the time I know that we think are realistic for the sake of major interest just to find the best for instance this curve the one that I have here I think so that we are very realistic I think I wouldn't be able to give you an answer right now I think it's just that often the changes that we would make temperature would be more important to allow the information on the other side I'm afraid that's the worst so does this kind of thing any other ideas you have that you don't know really and the other thing that if you want to I have said a lot of things about temperature or temperature I don't have the sources to translate it no I should say the purpose should not be that this is extended too much it would be that you use it with your mind so you give people the access to this as an executable and also how to call it from a macro and then you use it with your eyes because it's the main thing so that we normally it's specific in reference to a system like implementation or monitoring or something like that since it's that way we can do something else but of course it could be that at the score it should remain the simulator the modular whatever we should be on top of this but I will be looking how to call it to call it and it's very important that I use it as well yes so yeah I don't care if we are back to doing a little GAC management for my company that once was used for system identification now the idea is that this has dependent on non-parametric lines of temperature variation you can create something like a scenario of the life so I have the microphone but really as an organization is there an interface to all these structural parameters any professional all these structural parameters yes you would have to use it as the simulator in your program that's all yes you would call this an example basically we've been finding some kind of sample space yes and this is also like us yes this is the point it's very fast and it's a point example where you can get a lot of the same one that would be also very useful so when the AAC find their benchmark or identification numbers they were thinking that they could really move the effectiveness of the language on a single example we don't have to assume that someone is shooting their method to something that could benefit their purpose so yes we have some officer and the children or I didn't hear you very well so what kind of language do you use normally the boss the students the students and the children yes of course because it's the two sustained measurements so if you're a student building you can have your building uncertain because it can be generated by under a process put it there and then it changes precisely so and we have another example okay but the language is only concerned from the procedure where it's behind the solution so here's the language and this is your ground truth the model that you want is going to be another one so the language for you will be defined by the scratchers between the measurements that come from this ground truth and your modeling prediction this is a very nice point for myself how can we solve that's a good question so one way to support this one is to use it and give us the movie bugs and we will be able to fix the movie things that don't properly work for 30 days and then use it with the current simulation with the system identification and provide us the small report some slides on how it works let's say how your methods perform from the super again very much but you also have some resources or we have some resources left so 4 options so that's yes I'm sure yes sure if that's an option we can use it in the next update yes we can start with this one okay so you want to make the work so that it's about maybe some ways for example yeah yeah sure sure we'll be great yep how do we I didn't hear you yes I didn't think about that okay sure yes I think we can watch I was wondering if you have any questions yes I can make it available in the working room free folder yeah now I have one no but I can put it now in the members area yeah okay I mean this is almost as you see it now it's ready we just have to make sure it runs in the battery of which computer we're going on the information is that all of the data here is in the case of something else which one this curve right now we don't have the function I think that it will be easy we'll add it the custom curve and we add it for now we're just using this one from your third show those things we can easily change and we could also give these to us as comments like the botherer we'll just add them as an option there is one more thing which one which is the possibility to have actions on the benchmark which means you could say I would like a global repair or something of this sort but this will be for later or now we're just trying to make it as a simulator we will be able to support this system yeah I think we need to really make it because also this is Michael, I don't know what you're saying I don't know what you're saying yes so but in the world of Michael we should inform the stick and we we we should inform the stick okay
