Abstract

The synthesis and presentation of data determines (11) a unique axis, and determines (12) two concentric zones centered on the axis. The first set of information is constructed (13) and represented (14) by vectors that span from the center to the periphery of a concentric zone. The vectors are applied to (15) to a second set of information, to create a vector spanning between the concentric zones.

Description

<Desc / Clms Page number 1>

Method for synthesizing and restoring information representative of the operation of a distributed complex system, and corresponding system.

 The field of the invention is that of the processing and analysis of data representative of a distributed complex system.

 By distributed complex system is meant here a system generating a lot of information, of multiple origins, and requiring comparisons (according to origins, periods, users, ...) and a restitution in a synthetic form, allowing in particular a global, precise and rapid analysis of the system situation. It can for example be an engine or a set of engines, a power station, a refinery ... or even a structure such as a company, a company ... account can for example correspond to measurements of physical quantities, data analysis results, or even to survey results.

 Applications have already been proposed for graphically representing data tables. This is for example the case of the EXCEL software (registered trademark). However, these techniques only allow a static graphical representation of the information. In addition, the number of information retrieved is limited, and often uses specific files. For example, the known techniques do not allow several types of data to be effectively and simultaneously visualized and taking into account, for each of them, different origins and instants of measurements.

 Furthermore, these known tools only offer weak interaction with the user, and require solid training, in particular for the implementation of new analyzes or cross-checking of results.

 Finally, the corresponding results cannot be published or disseminated via the Internet. However, it is desirable that access to information is possible at any time and from any place. In the field of data solution via the Internet, there are no effective techniques today. We only know of

production d'histogrammes, correspondants à des résultats de vote. Ceux-ci sont basés sur une question, ou une mesure unique, et ne proposent qu'un affichage binaire : les pourcentages de oui et de non.

production of histograms, corresponding to voting results. These are based on a question, or a single measure, and only offer a binary display: the percentages of yes and no.

 In general, known systems do not allow the retrieval of a significant amount of information, with a view in particular to a multi-criteria analysis (for example a simultaneous comparison between several geographical areas, at two separate measurement instants ).

 Finally, known systems are not suitable for transmitting information (to control any type of display screen, and / or over a transmission network, such as the Internet). They assume a relatively heavy transmission, and each update requires a new complete transmission.

 The invention particularly aims to overcome these various drawbacks of the state of the art.

 More specifically, an objective of the invention is to provide a method, and corresponding means, allowing a knowledge and a first analysis, easy and intuitive, of a set of information representative of the functioning of a system.

 Another object of the invention is to provide such a method, which is suitable for taking statements of information on several sites, and for corresponding consultation anywhere. In particular, an objective of the invention is to allow the synthesis of the information collected from any terminal connected to a network (Internet or other), this information possibly being able to be distributed over several remote databases.

 The invention also aims to provide a data structure, or digital signal, making it possible to transmit easily and in a form requiring a very reduced bit rate, the data necessary for the synthesis of information on a display screen. This objective is twofold: the speed must be reduced during the first transmission of information, as well as in subsequent transmissions

<Desc / Clms Page number 3>

d'informations mises à jour (automatiquement ou suite à une requête de l'utilisateur).

updated information (automatically or following a user request).

 In general, an objective of the data transmission technique is to transmit as much useful information as possible (and to restore it efficiently) while minimizing the bit rate necessary for the transmission of this information. The invention aims to provide an effective solution to this objective.

 These objectives, as well as others which will appear subsequently, are achieved according to the invention using a method of synthesis and restitution of information representative of the operation of a distributed complex system (for example a motor , a power plant, a factory, a company,.), comprising at least two system elements (for example an engine cylinder or a company agency), said information being quantifiable (for example measured, or calculated from measurements ) and stored in at least one database contained in at least one server, said information being organized into at least one set of information (subsequently corresponding to a dial), themselves decomposable into at least two subsets of similar structure, corresponding to distinct time periods, each of said subsets grouping information from at least two of said system elements.

 According to the invention, the method comprises, for each of said sets of data, the following steps: determination of the coordinates of a single axis (the axis of the dial) for each of said sets of information; determining at least two concentric zones, centered on said single axis, and assigning each of said concentric zones to one of said subsets; restitution of first information, corresponding to one of said system elements, previously selected, for one of said subsets, on at least a portion of the periphery of the zone

concentrique correspondante ; détermination d'un jeu d'au moins une aiguille, ou un secteur, pour au moins une desdites zones concentriques, chacun desdits jeux d'aiguilles pointant respectivement sur la périphérie de ladite zone concentrique, toutes lesdites aiguilles étant axées sur ledit axe unique ; affectation auxdites aiguilles de secondes informations, correspondant à un ensemble d'au moins deux desdits éléments de système, pour le sous- ensemble associée à la zone concentrique correspondante, chacune desdites premières et secondes informations possédant une coordonnée angulaire unique.

concentric corresponding; determining a clearance of at least one needle, or a sector, for at least one of said concentric zones, each of said sets of needles pointing respectively to the periphery of said concentric zone, all of said needles being centered on said single axis; assignment to said second information needles, corresponding to a set of at least two of said system elements, for the subset associated with the corresponding concentric zone, each of said first and second information having a unique angular coordinate.

 This new and inventive approach makes it possible to carry out simultaneously, in addition to the direct reading of the restored information, at least three types of comparisons on the same dial: evolution between said periods for all of said information, presented on said peripheries; evolution between said time periods for said extracts, presented by said hands; comparisons between said first information (global information) and said second information (extracted information).

 Advantageously, the method of synthesis and restitution of information implements at least two sets of distinct information, each identified in particular by its single axis.

 According to a particular embodiment, said concentric zones are circular. Other forms are of course possible.

 Preferably, the method of the invention comprises a step of selecting, from among said system elements, the said system element (s) associated with the periphery of a concentric zone and / or using said needles. Said selection can in particular be cumulative and / or subtractive.

<Desc / Clms Page number 5>

Les informations prises en compte peuvent être de tout type (calculs, mesures,...). Au moins certaines desdites informations peuvent également être obtenues par sondage.

The information taken into account can be of any type (calculations, measurements, ...). At least some of this information can also be obtained by sampling.

 Advantageously, the method also includes a step of comparison between values obtained following at least one and the same measurement carried out at least twice, upstream and downstream of the evaluated process.

 According to a particular embodiment, the results of said comparison step are reproduced using a limited number of indicator lights.

 Preferably, the method of the invention comprises a step of determining a single general trend information, or general operating state, from at least some of said information.

 This unique general trend information can advantageously be restored by modifying the characteristics of a wallpaper.

- requête par ledit terminal de données d'image audit serveur ; - génération et transmission d'informations d'images dans ledit serveur, notamment desdites coordonnées d'axe unique. According to a particular embodiment, the method notably comprises the following steps: formulation of a request for synthesis and restitution of information, according to at least one predefined criterion, in a terminal; transmission of a form carrying said request to at least one server, via a transmission network;

analysis of said form, in said server, extraction of corresponding data in at least one database and calculation of said information, from said data, according to said request; - generation and transmission to said display data terminal allowing restitution on a screen of said information, in particular in the form of said angular coordinates;

- request by said image data terminal to said server; - generation and transmission of image information in said server, in particular of said single axis coordinates.

<Desc / Clms Page number 6>

The invention also relates to a system for synthesizing and restoring information implementing the method described above. Advantageously, such a system interconnects, via a telecommunications network (for example internet (registered trademark)), at least one of said databases to at least one display terminal, said method being implemented by said database and / or by said terminal.

 Other characteristics and advantages of the invention will appear more clearly on reading the following description of a preferred embodiment of the invention, given by way of simple illustrative and nonlimiting example, and of the appended drawings, among which : Figure 1 is a flowchart showing the main steps of the method of the invention; FIG. 2 presents, in a simplified form, the structure of the data transmitted within the framework of the method of FIG. 1; FIGS. 3a and 3b illustrate two examples of restitution of the information that can be produced from the very limited number of data carried by the signal of FIG. 2; FIG. 4 is a block diagram showing the main operations carried out by a system comprising a server and a terminal, and the corresponding data exchanges; FIG. 5 shows a particular example of implementation of the method of FIG. 1.

 The invention therefore relates to a new method for restoring a large number of information linked to each other, and which we want to be able to compare easily. This method aims in particular to allow a rapid and efficient interpretation of comparison, multi-criteria, which does not require the transmission of a large number of information, both for the first display and for updates.

 Figure 1 shows, schematically, the principle of the invention, for a

<Desc / Clms Page number 7>

cadran. Bien entendu, ce principe est duplicable, au cas où il est prévu plusieurs cadrans (figure 5).

dial. Of course, this principle can be duplicated, if several dials are provided (Figure 5).

 The method firstly comprises the determination 11 of the coordinates 111 of a single axis of the dial.

 Next, at least two concentric zones are determined (12), centered on the single axis. They can therefore be identified by an indication 121 of radius r ,, r2.

Each of these concentric zones is assigned to a subset of data, corresponding for example to a given period or instant. The different concentric zones then allow an analysis of an evolution over time.

 For each concentric zone, one obtains (13) then the first data, or information to be restored (for example a distribution according to a given criterion), which is displayed in the form of sectors along the concentric zone. Each sector can be identified by a simple polar coordinate (al, i; 01, k).

 We then obtain (14) a representation of a needle, or indicator, which will point to the concentric zone in question.

 Second information is then obtained (15), and assigned to the hands (or to corresponding representations, such as sectors, pointers, etc.). Again, a simple polar coordinate 151 (c2j; P ,,,) is sufficient to restore the information.

 This second information corresponds for example to an extract of the first information. In the case of an engine, the first information present on the contour of the concentric zone can correspond to the power curve of the engine, and the second information, to the power curve of one of the cylinders of the engine.

 This approach makes it possible to greatly reduce the speed necessary for the transmission of useful information. The corresponding data structure is illustrated in FIG. 2. This structure can for example correspond to the structure of a transmitted signal.

<Desc / Clms Page number 8>

Il comprend un préambule 21, comprenant : les coordonnées 211 de l'axe unique ; le rayon r, 212 de la première zone concentrique ; le rayon r2 213 de la deuxième zone concentrique.

It includes a preamble 21, comprising: the coordinates 211 of the single axis; the radius r, 212 of the first concentric zone; the radius r2 213 of the second concentric zone.

 Then, it suffices to issue polar coordinates 22, corresponding to the different polar coordinates (X, ss. With each new update, it suffices to provide a new series of polar coordinates 22.

 FIG. 3a presents an example of a dial that can be constructed directly, from the data in FIG. 2, and in particular the axis 31, the concentric zones 32 and 33 and the hands 34.

 In another embodiment, it is possible to provide a single set of needles, extending for example from the axis to the outer circle, as illustrated in FIG. 3b.

 FIG. 4 schematically illustrates an example of a system interconnecting a client and a server, for example via the Internet network (registered trademark).

 The client terminal includes means 41 for visual representation and capture of events, which in particular ensure intervention with the data and updating of the parameters 42 with means 43 for controlling parameters and calculation results, and for remote control means 41.

 The means 43 submitting, via the network, a form 44 to the server. The latter retrieves the corresponding parameters 45, then calculates the information 46, according to raw data, contained in at least one database 47.

 From this information, it generates (48) HTML code containing the results of the calculations and the parameters, which are transmitted (49) to the means 43. The latter then control the updating of the dynamic images 410 in the means 41 .

 According to a particular embodiment, the user interactions are controlled by Javascript (registered trademark).

 Furthermore, the means 41 submit (410) image parameters to the

<Desc / Clms Page number 9>

serveur, qui les récupère (411). Le serveur génère alors des images (412), notamment les cadrans, les diodes,..., puis transmet l'image correspondante (414) aux moyens 43.

server, which retrieves them (411). The server then generates images (412), in particular the dials, the diodes, etc., then transmits the corresponding image (414) to the means 43.

 As already mentioned, the information thus viewed can be of any type (information taken from engines, power stations, ...). It can also be information relating, for example, to the state of a company, made up of several agencies.

 A particular embodiment is shown below in more detail, corresponding to such a situation, which is easier to understand and to present.

 In this example, the basic concept consists in presenting in the form of a dashboard identical to those of cars, boats or planes, the information coming from the production, purchasing, stock database, finance, human relations, marketing or sales or satisfaction surveys, permanent or periodic uses and attitudes whatever the frequency, associated with segmentation characteristics contained in the database business.

 These dashboards can be used more generally to highlight any operating indicator (volume or production value, breakdown rate, cost of stock, parts supply time, manufacturing time .....) . It is recalled that, in the same way, various technical data can also be taken into account.

 In this example, we identify different categories of users, and in particular: executives in the broad sense needing all information, the sales manager needing information on their products and services associated with target customers, the sales manager human resources needing information on deficiencies in employee skills as well as on behavior resulting from the nature of contracts or seniority,

<Desc / Clms Page number 10>

les responsables des achats ou des stocks, de la production ou de la logistique, les différents responsables spécialisés au siège (plateau d'appel- production-logistique-SAV.....) qui ont besoin d'informations sur la qualité perçue et la satisfaction produite à chaque étape de la vente, les responsables délocalisés de centres, d'agences, de concessions... qui ont besoin d'avoir un retour sur la qualité de leur action spécifique comparée à celle de l'entreprise.

those responsible for purchasing or stocks, production or logistics, the various managers responsible for headquarters (call center, production, logistics, service, etc.) who need information on the perceived quality and the satisfaction produced at each stage of the sale, the relocated managers of centers, agencies, concessions ... who need to have feedback on the quality of their specific action compared to that of the company.

Information can be measured or determined in different ways. For simplicity, we consider the case of a survey questionnaire. This questionnaire is submitted to customers, prospects or others comprising main headings, listed below for illustrative purposes: before the sale, during the delivery of the service or product, - for the use of the service or product, on the human relationships, technical performance, after-sales sentiment, administration and invoicing,
The list is of course not exhaustive and each theme can be the subject of a set of specific questions presented in the form of a measurement scale, the number of modalities of which is provided for at 4 but which can optionally 'business be increased or reduced.

 Each main theme gives birth to a dial in the dashboard, as illustrated in Figure 5.

 Different options can be chosen: choice of cities of establishment: example a car manufacturer

 The different information is then provided at a frequency to be defined, going from day to year by means of an Internet / Intranet site which can be consulted by the customer and all the persons designated by him with a user account (login) authenticated by password. pass allowing both secure and individualized access in the nature of the information provided.

 A reception site for the client or the applicant of the concept is created for this purpose.

With their user account and password, the customer has access to their information. The client can of course define the nature of the information he associates with each user, which is detailed below.

A-General Information: the conduct of the company The whole product is made up of various elements: a background 51 called windshield responsible for representing the trend of information, its evolution or any other element proposed by

<Desc / Clms Page number 12>

l'entreprise ou demandé par le client, un ou des cadrans 521 à 523 chargés de véhiculer l'information chiffrée, des boutons de sélection 53 exclusifs ou cumulatifs permettant de passer à une autre information issue d'une segmentation de la base de données, des diodes 54 ou voyants lumineux d'alerte ou d'information susceptibles d'envoyer un message à l'utilisateur désigné par l'intermédiaire d'un message électronique.

the company or requested by the customer, one or more dials 521 to 523 responsible for conveying the encrypted information, exclusive or cumulative selection buttons 53 making it possible to switch to other information originating from a segmentation of the database, diodes 54 or warning or information lights capable of sending a message to the designated user by means of an electronic message.

The windshield 51
The bottom of the windshield can represent, at the customer's choice, a logo, a product, a circuit, a city or a region ... By default, the windshield contains a horizon illustrated in the form of a sky. The sky is divided into as many vertical parts as there are dials in the dashboards.

 Depending on the evolution of the company on each of the dial themes, the sky can go from "stormy" (in the event of deterioration) between the two periods to "variable" (in the event of stagnation), and finally to " sunny "(in case of improvement).

* Dials 521 to 523
Each dial contains for example the summary information collected by telephone, self-administered, mail or net survey or any other information to be represented (stock status, production, marketing, HR ...): on the circumference 55, light diodes 551 represent in percentage the number of responses of each modality (disappointed-satisfied without more-satisfied-delighted for example). Each diode representing 2% responses in the case of percentages, or quantities defined by the company symbolized by colors whose limits correspond to danger or safety identification zones (example, red for the risk zone of out of stock, orange for the emergency delivery or order area, green for the normal use area, and blue for total security or overstock).

<Desc / Clms Page number 13>

L'information de synthèse est la résultante de l'ensemble des variables de chaque thème. sur le cercle intérieur 56, des diodes lumineuses 561 représentent la même information pour la période précédente qui peut être temporelle ou décidée à la suite d'une action corrective menée par l'entreprise.

The summary information is the result of all the variables for each theme. on the inner circle 56, light diodes 561 represent the same information for the previous period which may be temporal or decided following a corrective action carried out by the company.

l'évolution de la perception entre deux périodes. All of these two pieces of information make it possible to grasp dynamically

the evolution of perception between two periods.

* On the steering wheel rim Each button 57 represents a division of the company. This breakdown can be geographic by management region, by agency, center or concession, product or by distribution channel ...

 A global button 58 makes it possible to have the information of the company all confused divisions.

 The selection of a division is illustrated by the coloring of the button then serving as an indicator light. When a cutout is selected, the light-emitting diodes indicate the information specific to the selected selection.

 Each selection can be cumulative or subtractive. Thus a company can carry out by its multiple selections, groupings or exclusions compared to the global of products, centers ...

The needles
However, in order to be able to establish a comparison between the breakdown chosen and the company without its entirety, the hands 60 and 61 contained in the dials indicate the level reached by the company, all cuts combined, unless ad hoc request from the client.

The external needle 60 represents the whole of the company during the period and the internal needle 61, the whole of the company during the previous period.

* The buttons on the steering wheel branch They correspond to choices of segmentation or cutting of the data

<Desc / Clms Page number 14>

l'entreprise sur des fonctions ou services identifiés. Par exemple : les boutons sur la branche gauche du volant concernent les données commerciales de l'entreprise en matière de segmentation de clientèle.
Ces segments peuvent résulter de caractéristiques signalétiques, de produits achetés, d'importance du client pour l'entreprise ou tout critère susceptible d'être identifié dans la base de données internes de l'entreprise.

the company on identified functions or services. For example: the buttons on the left side of the steering wheel relate to the company's commercial data in terms of customer segmentation.
These segments can result from descriptive characteristics, products purchased, importance of the customer for the company or any criterion capable of being identified in the internal database of the company.

 The selection of a button is represented by its transformation into an indicator light.

 The selections can be multiple and add to a cutting selection on the rim of the steering wheel.

 The diodes contained in the dials then display the results corresponding to the selections made. The whole is always represented by the hands. the buttons on the right branch of the steering wheel relate to the segmentation of employees when they can be associated with the customer relationship in the case of identified employees (technicians-salespeople ...).

 Selections can be based on seniority, type of contract, training received, etc.

 This innovative approach makes it possible to link the predispositions of customers in a faithful relationship according to the nature and quality of the people who are their contact.

The human resources decision-maker may wish to modify his recruitment, training and remuneration policy to act on customer loyalty and his staff.

* The buttons in the center of the steering wheel Still within the framework of the illustrative example, we can provide: the "profiling" button, which allows access to additional information obtained in the survey and not falling within the scope

de la mesure de la satisfaction. Ces informations concernent de la signalétique, des attitudes, des usages.

satisfaction measurement. This information concerns signage, attitudes, uses.

The information is represented in the form of vertical histograms or any other new creation of dials or indicators having their own color codes. In the case of a selection using buttons on the steering wheel, the graphics show the comparison with the whole company.

Raw selection 62 or corrected selection 64: in order to be able to visualize both the results of the survey which may require criteria related to the structure of the population to be studied and the quantities of which may differ from reality, that reality itself, it can be chosen to select the raw data which are those of the survey or the rectified data which are corrected of the real proportions of the company subject

that the latter transmits them.

* selection according to the survey method A selection can also be made depending on the mode of administration of the survey. If the company decides to collect its information by different means, each of the means can be observed.

* The horizontal diodes in the center of the dashboard
Two rows of central diodes 54 make it possible to display the impact of the survey on the respondent in the event of an survey. Indeed, a question at the start of the survey requires overall satisfaction. This same question is asked again at the end of the survey in order to measure the development and the action of the detailed reflection on the respondent.

 Ten diodes, each representing 10% of the population surveyed, are displayed according to the color codes used for the dial diodes.

 These diodes could also be used to highlight any other global data of the company, such as CA, market rate, scrap rate,

B-Detailed information: steering
By clicking in each of the counters, a window appears allowing the data to appear in the form of a table containing the quantitative information in digital form for the selection or selections in order to ensure the statistical reliability of the information contained. Reliability is also mentioned in the form of a probability in the case of a non-exhaustive survey.

 The percentages by opinion are also indicated for the current period and the previous period.

 The question mark 63 in the center of the dial displays a window containing all the questions or variables used and relating to the theme of the dial.

 All the questions or variables are mentioned in text and their answer in graphic form of horizontal percentage histograms using the same colors illustrating the opinion measured.

 These illustrations appear according to the selection made using selected buttons.

 In the case of a segment selection, a histogram shows the overall average of the company in order to make a visual comparison.

 By pressing this button S 65 in the central dial to materialize the segments, a series of windows appears containing a question of the theme for each of the segmentations. For this question or variable, the answers are provided in the form of horizontal histograms for each segment and possible selection of the steering wheel. For each segment, the first question or variable appears with the different answers related to it. We move from one question to another using the arrow keys.

 We understand that it is easy to adapt the principle described above to other types of information, whatever their origins. Thus, the invention allows effective monitoring of any type of information representative of the operation of a system.

complexe réparti. La transmission et le codage de ces données sont très simples et très efficaces : cela peut se résumer essentiellement à des coordonnées polaires (les informations fixes étant préalablement fournies).

distributed complex. The transmission and coding of these data is very simple and very effective: this can essentially be summed up in polar coordinates (fixed information being provided beforehand).

 The system can advantageously operate on a client server mode using the HTTP protocol. The web server is instructed by CGI scripts to generate HTML pages and images that can be viewed and interpreted by a web browser. Scripts connect to a data server where they get the information they need.

 The images are generated on the fly by CGI scripts in GIF format by the use of a graphic library: GD developed by Boutell. Com Inc. The needles and circular diodes and texts of each counter are inserted in a reference image representing the bottom of the counter. The hands and the diodes are positioned and colored according to static parameters transmitted by the POST method.

 The dashboard in Figure 5 is therefore constructed by superimposing 6 layers: the page background (in the form of an image which can vary depending on the criteria selected), the dashboard background (gray), the counters and diodes, the steering wheel, buttons, interaction zones.

 The layers are produced by adding DHTML layers.

 According to a variant, the images can also be calculated on the terminal thereby limiting the information transmitted between the server and the terminal. The standard used is then the SVG ("Scalable Vector Graphic" in English) of the World Wide Web Consortium. The layers are superimposed within the same DHTML layer in the

<Desc / Clms Page number 18>

graphique vectoriel SVG.

SVG vector graphic.

The data is stored on an SQL server. Subject to the available drivers, any data server is attackable. The data can optionally be stored as a static file. Data is not required to come from a single server.

 The language can be used PHP language. It allows all the necessary operations: data extraction requests, value calculations, generation of images (access to a GD library), generation of layers.
