This report is an initially study of the whole processes in the manufacturing aims to capturethe current problems into groups of categories and prioritize the problem solving according tothe frequency of the defects detection, the root causes are indentified and assessment ofFMEA on the problems occurrence.Research method is performed by interviewing the key persons who are representatives fromthe units, then use tools of quality improvement to analyze each step (Affinity, Pareto,Ishikawa and FMEA).Conclusion of the study found that Burapha Wood Company is currently facing with threecategories of problem, those are Machinery, Competency, Timber Drying and others with thelist of problem are consisted.The Two sided planer machine is a first prior to be undertaken of solution. Where the rootcauses are ignorance of workers not follow the machine’s instruction in such of reset themachine before operating and the record form has not filled when problems occurrence.The processes where the company has to focus is on the Two sided planer machine which is ahighest prioritized by pareto diagram based on FMEA analysis, but considering with thepotential and possibility of solution Burapha Wood Company must intend on timber drying.These problems are partial platform of improvement of manufacturing quality to get a COCcertification.

The thesis focuses on the selection process and the implementation of the new information system (hereinafter "IS") in a manufacturing company. This is achieved by detailing characteristics of all individual phases and steps of the selection and implementation processes in the context of one appointed company. The characteristics analysis identifies key factors which need to be managed well by the company in order to accomplish a desired outcome. The thesis also includes a generic and coherent framework and it concludes with a comprehensive proposal which can be used as a tool for a successful selection and implementation of the new IS.

This diploma thesis deals with selection and implementation of information system for company providing IT services. Theoretical background concerning the topic is described in the first part. Then, the company is analyzed and based on the results new information system is suggested. Implementation strategy and risk analysis for implementation of new information system to corporate environment are designed in this thesis. Implementation of the information system is economically evaluated at the end of this thesis.

Two optimisation problems were considered, in which market exposure is indirectly controlled. The first one models the capital of a company and an independent portfolio of new businesses, each one represented by a Cram\'r-Lundberg process. The company can choose the proportion of new business it wants to take on and can alter this proportion over time. Here the objective is to find a strategy that maximises the survival probability. We use a point processes framework to deal with the impact of an adapted strategy in the intensity of the new business. We prove that when Cram\'{e}r-Lundberg processes with exponentially distributed claims, it is optimal to choose a threshold type strategy, where the company switches between owning all new businesses or none depending on the capital level. For this type of processes that change both drift and jump measure when crossing the constant threshold, we solve the one and two-sided exit problems. This optimisation problem is also solved when the capital of the company and the new business are modelled by spectrally positive L\'vy processes of bounded variation. Here the one-sided exit problem is solved and we prove optimality of the same type of threshold strategy for any jump distribution. The second problem is a stochastic variation of the work done by Taylor about underwriting in a competitive market. Taylor maximised discounted future cash flows over a finite time horizon in a discrete time setting when the change of exposure from one period to the next has a multiplicative form involving the company's premium and the market average premium. The control is the company's premium strategy over a the mentioned finite time horizon. Taylor's work opened a rich line of research, and we discuss some of it. In contrast with Taylor's model, we consider the market average premium to be a Markov chain instead of a deterministic vector. This allows to model uncertainty in future conditions of the market. We also consider an infinite time horizon instead of finite. This solves the time dependency in Taylor's optimal strategies that were giving unrealistic results. Our main result is a formula to calculate explicitly the value function of a specific class of pricing strategies. Further we explore concrete examples numerically. We find a mix of optimal strategies where in some examples the company should follow the market while in other cases should go against it.

The theoretical study of nonlinear expectations is the focus of attention for applications in a variety of different fields — often with the objective to model systems under incomplete information. Especially in mathematical finance, advances in the theory of sublinear expectations (also referred to as coherent risk measures) lay the theoretical foundation for modern approaches to evaluations under the presence of Knightian uncertainty. In this book, we introduce and study a large class of jump-type processes for sublinear expectations, which can be interpreted as Lévy-type processes under uncertainty in their characteristics. Moreover, we establish an existence and uniqueness theory for related nonlinear, nonlocal Hamilton-Jacobi-Bellman equations with non-dominated jump terms.
