Aplikace fuzzy logiky pro vyhodnocení dodavatelů firmy / The Application of Fuzzy Logic for Rating of Suppliers for the Firm

Ondruch, Lukáš January 2021 (has links)
The master’s thesis deals with the use of fuzzy logic for evaluating the quality of suppliers of IT goods and other material for a selected company. The fuzzy model should facilitate decisions when selecting individual suppliers who should deliver goods for the implementation of IT projects. The model created in Microsoft Excel and MathWorks MATLAB should be helpful to the company's management and sales representatives.

Uplatnění statistických metod při zpracování dat / The Use of Statistical Methods for Data Processing

Vaněk, Tomáš January 2016 (has links)
The subject of this master’s thesis is to analyze and evaluate the economic indicators of selected company and comparison of these indicators with the nearest competitors. The thesis is divided into three main sections. First part is theoretical and contains information about used economical and statistical terms. Second part contains of analysis of economic indicators, comparison of actual and predicted values and comparison with the nearest competitors. In order to predict future values of indicators, on selected indicators appropriate regression function has been applied. The last part of thesis contains of program created by using VBA in MS Excel, which is designed to calculate the economic indicators, and the part containing proposals for improving the situation of company.

Examination and implementation of knowledge based engineering in clearance analysis : A study off external stores and its compatibilities on the Gripen aircraft

Larsson, Malte, Jonsson, Johan January 2019 (has links)
When working with complex aircraft design it is necessary to be able test configurations easily. At Saab this is done in several ways. When looking at the weapons integration on the Gripen Aircraft, clearance analysis (called feasibility studies at Saab) are created to evaluate if new external stores can be mounted. This is done manually in CATIA by measuring and evaluating the result. To ease the work when performing these repetitive tasks, it is possible to take advantage of Knowledge Based Engineering, KBE. This thesis revolves around implementing KBE in the process. The approach is to create a configurator that can handle the different external stores and perform the required tasks. The end result is a configurator with a Graphical User Interface, GUI, in which the user gets help with the feasibility study and which requires light manual input from the user. The configurator performs the study and produces a Word report for the user to examine. The resulting time saving is around 75 to 80 percent from the original process. The conclusion is that the configurator can facilitate the feasibility studies at Saab by reducing the time and lower the threshold for the user. Even though the process is not fully automated, the configurator is judged to perform at a satisfying degree.

För en bättre arkivvärld : Verksamhetsbaserad arkivredovisning inom kommunal och regional kulturförvaltning

Hammarlund, Ottilia, Osses Moreira, Salomé January 2023 (has links)
In 2009, the Swedish National Archive introduced a new way of maintaining and cataloguing documents within the archives, which all national governments were to implement within four years. But for the local gov- ernments it was voluntary and, moreover, they did not have the same requirements to fulfil the guidelines that the National Archives put forward. The result was completely different archival descriptions.  The aim of this investigation is to examine whether formation of a functional classification structure can be streamlined, with the goal of helping the municipalities and counties succeed in developing an efficient, concise and functioning archival description. This search is based on a systematic document analysis, in which studied and revised seven municipalities and six counties in Sweden.  Certain aspects recur in all archive descriptions that were included in the study, such as the municipalities' and counties' function for the local library organisations and promoting local culture. Differences are visible in the structure of the archival descriptions and the individual unique functions developed to suit the local government.  The differences between archive descriptions are due to three main factors: the organizational structure, the archivist’s experience and the financial conditions. All three aspects affect the work to produce a functional clas- sification in different ways.  The discussion is based on Terry Eastwood's and John Robert's archive theory regarding the archivist's re- sponsibility and the focus on keeping the original in the archive. In order to maintain the principle of provenance. This theory was used in the study in order to get an idea of whether a standardized functional classification is possible, which we concluded that it is and desirable. Mainly, because it creates an overall perspective of the archive.

Approche bayésienne pour la localisation de sources en imagerie acoustique

Chu, Ning 22 November 2013 (has links) (PDF)
L'imagerie acoustique est une technique performante pour la localisation et la reconstruction de puissance des sources acoustiques en utilisant des mesures limitées au réseau des microphones. Elle est largement utilisée pour évaluer l'influence acoustique dans l'industrie automobile et aéronautique. Les méthodes d'imagerie acoustique impliquent souvent un modèle direct de propagation acoustique et l'inversion de ce modèle direct. Cependant, cette inversion provoque généralement un problème inverse mal-posé. Par conséquent, les méthodes classiques ne permettent d'obtenir de manière satisfaisante ni une haute résolution spatiale, ni une dynamique large de la puissance acoustique. Dans cette thèse, nous avons tout d'abord nous avons créé un modèle direct discret de la puissance acoustique qui devient alors à la fois linéaire et déterminé pour les puissances acoustiques. Et nous ajoutons les erreurs de mesures que nous décomposons en trois parties : le bruit de fond du réseau de capteurs, l'incertitude du modèle causée par les propagations à multi-trajets et les erreurs d'approximation de la modélisation. Pour la résolution du problème inverse, nous avons tout d'abord proposé une approche d'hyper-résolution en utilisant une contrainte de parcimonie, de sorte que nous pouvons obtenir une plus haute résolution spatiale robuste à aux erreurs de mesures à condition que le paramètre de parcimonie soit estimé attentivement. Ensuite, afin d'obtenir une dynamique large et une plus forte robustesse aux bruits, nous avons proposé une approche basée sur une inférence bayésienne avec un a priori parcimonieux. Toutes les variables et paramètres inconnus peuvent être estimées par l'estimation du maximum a posteriori conjoint (JMAP). Toutefois, le JMAP souffrant d'une optimisation non-quadratique d'importants coûts de calcul, nous avons cherché des solutions d'accélération algorithmique: une approximation du modèle direct en utilisant une convolution 2D avec un noyau invariant. Grâce à ce modèle, nos approches peuvent être parallélisées sur des Graphics Processing Unit (GPU) . Par ailleurs, nous avons affiné notre modèle statistique sur 2 aspects : prise en compte de la non stationarité spatiale des erreurs de mesures et la définition d'une loi a priori pour les puissances renforçant la parcimonie en loi de Students-t. Enfin, nous ont poussé à mettre en place une Approximation Variationnelle Bayésienne (VBA). Cette approche permet non seulement d'obtenir toutes les estimations des inconnues, mais aussi de fournir des intervalles de confiance grâce aux paramètres cachés utilisés par les lois de Students-t. Pour conclure, nos approches ont été comparées avec des méthodes de l'état-de-l'art sur des données simulées, réelles (provenant d'essais en soufflerie chez Renault S2A) et hybrides.
