Повний текст джерелаThis thesis addresses the prediction of product quality and improving the performance of diagnostic alarms in a semiconductor facility. For this purpose, we exploit the alarm history collected during production. First, we propose an approach to model and estimate the degradation risk of the final product associated with each alarm triggered according to its activation behavior on all products during production. Second, using the estimated risk values for any alarm, we propose an approach to predict the final quality of the product's lot. This approach models the link between process alarm events and the final quality of product lot through machine learning techniques. We also propose a new approach based on alarm event text processing to predict the final product quality. This approach improves performance and exploits more information available in the alarm text. Finally, we propose a framework for analyzing alarm activations through performance evaluation tools and several interactive visualization techniques that are more suitable for semiconductor manufacturing. These allow us to closely monitor alarms, evaluate performance, and improve the quality of products and event data collected in history. The effectiveness of each of the above approaches is demonstrated using a real data set obtained from a semiconductor manufacturing facility

Повний текст джерелаThis work has been conducted to understand the destabilization of UHT milk with raw milk previously contaminated by proteolytic Pseudomonas. Infrared spectroscopy Fourier transform has been explored in order to detect the cause and predict the stability of milk before their technological transformations. First, the selection of 32 strains of the genus Pseudomonas based on their proteolytic character has shown that there is a variability of proteolysis. In a second step, the monitoring of the stability of UHT milk previously and independently inoculated by nine strains of P. Fluorescens, with different proteolytic potential, showed that this heterogeneity of proteolysis also happened in UHT milk. The addition of protease AprX in raw milk before UHT treatment also resulted in a destabilization of UHT milk before the end of 90 days of storage, confirming the role of this enzyme in the phenomenon of destabilization. For each experiment performed, the destabilization resulted in increases of non-casein nitrogen contents (NCN), indicating proteolysis of casein micelles. The results obtained by HPLC analysis coupled with mass spectrometry of NCN fractions of milk destabilized showed that AprX had a large action spectrum and was able to hydrolyze β, s1, s2 and κ casein. In a third step, FTIR spectroscopy allowed us to determine the threshold for detection of milk contaminated with bacteria of the genus Pseudomonas and the discrimination threshold of milk containing proteolytic Pseudomonas from milk containing non-proteolytic Pseudomonas (5. 102 CFU / mL). However, further works have to be undertaken to use FTIR spectroscopy as a tool for predicting the stability of milk

Повний текст джерелаThe microelectronics industry is a highly competitive field, constantly confronted with several challenges. To evaluate the manufacturing steps, quality tests are applied during and at the end of production. As these tests are discontinuous, a defect or failure of the equipment can cause a deterioration in the product quality and a loss in the manufacturing Yield. Alarms are setting off to indicate problems, but periodic alarms can be triggered resulting in alarm flows. On the other hand, a large quantity of data of the equipment obtained from sensors is available. Alarm management, interpolation of quality measurements and reduction of correlated equipment data are required. We aim in our work to develop generic methods of multi-variate analysis allowing to aggregate all the available information (equipment health indicators, alarms) to predict the product quality taking into account the quality of the various manufacturing steps. Based on the pattern recognition principle, data of the degradation trajectory are compared with health indices for failing equipment. The objective is to predict the remaining number of products before loss of the performance related to customer specifications, and the isolation of equipment responsible for degradation. In addition, regression- ased methods are used to predict the product quality while taking into account the existing correlation and the dependency relationships in the process. A model for the alarm management is constructed where criticality and similarity indices are proposed. Then, alarm data are used to predict the product scrap. An application to industrial data from STMicroelectronics is provided

Повний текст джерелаThe aim of the study is to analyse the impact of texture/material couple of polypropylene injection pieces on the characteristics of the surface and the Perceived Quality. In order to answer this question, we developed a system for the characterization and the prediction of the appearance of the texture. It includes a scale of characterization (composed of 12 descriptors) and two «instruments» of characterization: a visual panel and instrumental panel. The instrumental panel is composed of 12 predictive models of the 12 descriptors. The models are built on sensory ratings and the measures of 3 instruments. The characterization system is used on a set of samples of injected polypropylene making it possible to defines the aesthetics descriptors of the grain (“fantasy” descriptors) and descriptors that differentiate the materials (gloss descriptors). An exploration of the impact of the material composition, the topography of the grains and the response of the material to the topography during the injection moulding was performed on a group of samples with 4 grain, 3 materials and 3 colors. Finally, a large customer survey was conducted. The results have been exploited to establish how the characteristics evaluated by the panel are related with the perception of quality. It appears that the aesthetics of the grain and its association with the color and then its gloss, mostly impact the judgments of quality. Although prospective, this work allows the development of the "genes" of grains suitable for different types of customers, by considering the influence of the couple "grain geometry - visual potential of the material."

Повний текст джерелаFaulty software have expensive consequences. To mitigate these consequences, software developers have to identify and fix faulty software components before releasing their products. Similarly, users have to gauge the delivered quality of software before adopting it. However, the abstract nature and multiple dimensions of software quality impede organizations from measuring software quality. Software quality metrics can be used as proxies of software quality. There is need for a software process metric that can guarantee consistent superior fault prediction performances across different contexts. This research sought to determine a predictor for software faults that exhibits the best prediction performance, requires least effort to detect software faults, and has a minimum cost of misclassifying components. It also investigated the effect of combining predictors on performance of software fault prediction models. Experimental data was derived from four OSS projects. Logistic Regression was used to predict bug status while Linear Regression was used to predict number of bugs per file. Models built with Change Burst metrics registered overall better performance relative to those built with Change, Code Churn, Developer Networks and Source Code software metrics. Change Burst metrics recorded the highest values for numerical performance measures, exhibited the highest fault detection probabilities and had the least cost of mis-classification of components. The study found out that Change Burst metrics could effectively predict software faults

Повний текст джерелаThe rapid decline in light crude oils requires to convert heavy petroleum fractions into more valuable products (naphtha, diesel, lubricants, etc.). In this context, hydrocracking process (HCK) consists on upgrading vaccum gas oil (VGO) into high quality products. The quality of petroleum products is based on some chemical and physical properties that should fulfill prerequisite specifications. The hydrocracking process optimization requires to set up time consuming and costly experiments for developing catalysts and setting operating conditions. High throughput experimentation (HTE) units are then increasingly used at IFPEN. However, these units do not enable to obtain end products. Otherwise, predictive models were developed in order to understand and predict the impact of operating conditions about products quality. However, some complex properties are very difficult to model and require a better understanding. This work is mainly concerned with the understanding of diesel cloud point (CP) and viscosity index (VI) of base oils. Two analytical techniques were used: the two-dimensional gas chromatography (GC×GC) that enables to identify hydrocarbons compounds in petroleum products and the 13C nuclear magnetic resonance (NMR) spectroscopy which provides structural characteristics of these compounds. A sparse multivariate regression (sparse Partial Least Squares) was performed using chromatographic and spectroscopic data. The sparse PLS is derived from classical PLS. It allows to reduce the number of factors by performing a variable selection. The selected factors are the most correlated to the property to model. Globally, this approach enabled to better understand how hydrocarbon compounds (nparaffins, isoparaffins, aromatics,…) and their molecular characteristics (carbon number, degree of branching,…) affect the diesel CP and the VI of base oil. Furthermore, the good performances of developed sparse PLS models show that it is possible to access to the products quality when using HTE units. Kriging models were also developed. Kriging is an interpolation method that predicts the value of a function at a given point by computing a weighted average of the known values of the function in the neighborhood of the point. Kriging models have local aspect which is well adapted to complex data. Its probabilistic approach enables to provide an estimate of predicted value uncertainty. Results show that kriging improves predictive performances for both diesel CP and VI of base oil. This approach is quite innovative in modelling of petroleum products properties. When using HTE units, it allows to estimate the VI of base oil more easily than from chromatographic or spectroscopic data which are not available for the refiners

Повний текст джерелаThis research answers a main question : determine which attribute has more value than an other and for which quality aspect. An analysis framework is developped to interpret the concept multidimentionality. Three research axes are developped : 1- which are the product quality attributes used by the consumer. 2- which is their relative importance. 3- which is personnal factors influence on product quality attributes. A qualitative (interviews and prompt protocols) and quantitative methods (conjoint measurement, cluster and discriminant analysis, log-linear and peterson & mahajan partial square omega) are used to test the hypotheses. Two principal theorical consequences can be drawn from this research. The olson hypothesis cannot been generalized and no personnal factors allow to differentiate a group of consumers from another
