Texto completoStatistical Process Control (SPC) is an effective approach for improving quality and productivity of aproduction process. Among the SPC tools, control chart, as themost important and primary tool, has been widely used to monitor and determine whether a production process is in-control or not. An indispensable assumption for the development of control charts is that the process parameters (the in-control mean and standard-deviation) are assumed known. In practice, the distribution of the data and the process parameters are rarely known, and the process parameters are usually estimated from an in-control historical data set (Phase I). When these parameters are estimated, the performance of the control charts differs from the known parameters case. Recently, some authors have studied the impact of the parameters estimation, but more work is needed. In this thesis, we will investigate the properties (in terms of theRun Length) of some control charts for the mean inthe case of estimated parameters,which have not been researched till now, such as Run Rules Chart, Synthetic Chart, VSI Chart and VSS Chart. The first goal of this thesis is to evaluate the performance of these control charts when the process parameters are estimated, to compare them with the case when the process parameters are assumed known and to demonstrate that the performance is quite different especially when the number of samples used during the Phase I is small. The second goal of this thesis is to suggest the sample sizes and to provide new optimal chart constants for calculating the limits of these control charts in the case of estimated parameters, which are very useful in practice

Texto completoStatistical Process Monitoring (SPM) is a widely used methodology, based on the implementation of control charts, for achieving process stability and improving capability through the reduction of the process variability. The selection of a suitable control chart depends on the type and distribution of he data. When there are several quality characteristics, multivariate control charts have to be adopted. But there is a specific category of multivariate data which are constrained by definition and known as Compositional Data (CoDa). This thesis makes an attempt to systematically propose new control charts for the for compositional data that have not yet been proposed so far in the literature. Hotelling T2-CoDa control chart in the presence of measurement error and MEWMACoDa control chart in the presence of measurement error has been proposed for compositional data. Furthermore, some nonparametric charts to monitor compositional data has also been proposed. The performance of each control chart has been studied and the optimal parameters have systematically been evaluated. Real life compositional data examples have been used in order to study the performances of the proposed charts

Texto completoThe Statistical Process Control (SPC) is an effective method based on statistics and used to monitor production. Control charts are the most important and primary tools of SPC. An indispensable assumption for the development of control charts is that the process parameters μ0 and 0 are assumed constant. In practice, the process parameters are often variables and the use of the coefficient of variation seems to be an interesting alternative. In this thesis, we will investigate the properties (in terms of the Run Length) of some control charts for the coefficient of variation in the case of known parameters, which have not been researched till now, such as Run Rules Chart, VSI Chart and VSS Chart. In addition, a Shewhart control chart for the coefficient of variation with estimated parameters is proposed. The performance of each control chart has been evaluated and the optimal parameters were systematically computed. An empirical validation of the results has been developed for real industrial processes

Texto completoStatistical Process Control (SPC) is a method of quality control based on statistics and used to monitor production. Monitoring the coefficient of variation is an effective approach to SPC when the process mean µ and standard deviation σ are not constant but their ratio is constant. Until now, research has not investigated the monitoring of the coefficient of variation for short production runs. Viewed under this perspective, in this thesis, we will propose new methods to monitor the coefficient of variation for a finite horizon production, we will investigate the properties (in terms of the Truncated Run Length) of some control charts for the coefficient of variation in a Short Run context in the case of known parameters, such as the one-sided Shewhart Chart, the Run Rules Chart, the VSI and VSS Charts. The performance of each control chart has been evaluated by developing statistical measures of performance appropriate in a Short Run context and the optimal parameters were systematically computed. An empirical validation of the results has been developed for real industrial processes

Texto completoBecause of the process complexity (multi-scale data, large number of characteristics variables and etc.), process monitoring has become a big challenge in control engineering, in order to assure quality and safety of processes. In this thesis work, we are interested in multi-scale monitoring approaches, which are based on combination between wavelet analysis and data-driven techniques. Firstly, we have established a general framework of statistical distribution of the wavelet coefficients (approximations and details) as part of the multi-resolution analysis. Indeed, we derived the distribution parameters of wavelets coefficients. Then, we developed new control charts for mean change (AJ , OWave, BiWave-T2 et BiWave-MEWMA), variance change (DeWave) and mean/variance change (AJ-DeWave scheme). In addition, we shown equivalencies between statistical control techniques and wavelet transforms. Moreover, a new technique -CoWave- is proposed, in order to estimate the mean change time (fault isolation). The CoWave is equivalent to the maximum likelihood estimator. Finally, statistical characteristics of wavelets coefficients in the case of autocorrelated and non-normal data are presented

Texto completoIntegrated solutions are evolving to cope with the digitalization of manufacturing processes. One area of improvement is developing new strategies joining maintenance and quality control. A popular hypothesis used in these integrated models is considering that quality control comes down to monitoring a single process or product characteristic. However, for complex systems, this assumption is seldom satisfied as the number of characteristics grows and they can have potential correlations. In fact, a multivariate control chart is more suitable to guarantee better performances of drift detection. Following this perspective, the main objective of this thesis consists in developing new maintenance decision rules based on produced items’ quality data. Multivariate control charts are used to provide detection and identification of potential process shifts and adaptive maintenance actions are triggered, targeting system components responsible for the deterioration of the produced items’ quality. First, a preliminary study is led to highlight the impact of multivariate control charts on the decision making process. Next, integrated maintenance decision rules for condition based and predictive maintenance are proposed using multimodal control charts. The developed decision rules are applied in the context of a simulated manufacturing process exhibiting a quality defect appearing in different dynamics (fast and slow drifts). The new strategies proposed in this thesis have been validated through the development of analytical models expressing the profit of the manufacturing system. This profit was maximized based on decision variables (sampling period and critical intervention threshold) and the existence of optimal solutions has been demonstrated through simulation. The robustness of the developed models has been proven by sensitivity studies, followed by comparative studies in order to highlight the impact of the proposed strategies

Texto completoThe current production industry is characterise by significant progress: a massive increase in high technology, the emergence of exigent customers, competitive markets, varied product quality, and random demands required the collaborations of the inter-related aspects of production. The production, maintenance, and quality are the most critical aspects of the industrial system. We are interested in optimising maintenance that plays a critical role in customer satisfaction, sustainability, and the development of companies. Our study is centred on developing production and maintenance integrated into a control chart of quality policy. We propose new integrated maintenance strategies with an in-depth analysis of the continuous production process reliability improvements and treated under customer requirements (Service, quality, and cost) constraints. The integration and optimal coordination of these factors of production is not easy and represent a challenge for industrial companies, and are more challenging with multi-assignable causes of production process variation. To address this problem, this research work employed the use of a control chart tool in combination with the AFNOR principles known as Rule of seven as involved in quality management. To monitor, analyses and direct appropriate maintenance actions for continuous system reliability improvements along the different multiple process scenarios as decision levels. We use the interactions between the production process and product quality for strategies of maintenance which reduce the failure of the production system by improving process reliability and reducing the no conformal products. The study Significantly focused on quality, quality tools, and their applications in production and maintenance control. The technique we used to optimise the maintenance and quality control of an integrated production system is a control chart tool based on statistical measurement and analysis of quality parameters. We model different production problems and develop a control policy for randomly failing production systems that must satisfy customer requirements dynamically throughout the finite production horizon. We introduced a mathematical model to minimise the total costs of production, inventory, maintenance, and quality control. The optimisation of the maintenance strategy was integrated into a control chart tool information. Based on the production rate variation and its impact on machine degradation the number of maintenance, times, and intervals needed for prudent decision-making is determined by the developed algorithm. In this context, this research presents the derivation for different cases of all the probabilities for the process to be in or out of control, the average run lengths, and the restoration cycle durations. Based on the degradation factor, new failure rate equations are formulated, and then the average failure rate for each case, we formulated different maintenance cost optimisation models. The proposed approach is useful for precise calculation and minimisation of the total maintenance cost. Which optimises total production cost considering all possible production process statuses due to multiple causes. Our work contributes to the emergence of quality management and performance improvement techniques that will contribute to the development of production companies

Texto completoThe continuous improvement of the yield of a production line is a significant goal for the competitiveness of the facility. In the context of integrated circuit manufacturing, the introduction of new increasingly complex technologies makes the statistical tools traditionally used insufficient to prevent process failures. Consequently, new statistical techniques have been developed to improve or replace some existing tools and also to form some new ones. Thus, an improvement process is proposed. When a decrease of yield is observed, it first needs to be characterized. The characterization is achieved by a spatial analysis of the silicon wafers on which the integrated circuits are manufactured. . .
