The theory and practice of optimization as a tool for successful decision-making when designing new products and processes: While the focus is on the formulation of optimization problems, also attention is given to solution methods, software implementation, and analysis and interpretation of solutions.The book helps the chemical engineer in formulation, solving and analyzing different classes of optimization problems (LP’s, NLP’s MIP’s) at different scales (from individual equipment and product up to plant and supply chain). This book is an excellent guide and companion for undergraduate, graduate students as well as professional practitioners.

Tato bakalářská práce se zabývá problémem využití optimalizace procesů ve strojním inženýrství. Je v ní vytvořen optimalizační model pro optimalizaci řezných podmínek při soustružení. Problém byl zpracován a naprogramován v systému GAMS jako lineární i nelineární problém. Omezující podmínky jsme definovali obecně pro několik druhů technologických procesů.

Abstract Process optimization is the discipline of adjusting a process to optimize a specified set of parameters without violating engineering constraints. This article reviews data-driven optimization methods based on genetic algorithms and stochastic models and demonstrates their use in powder-bed fusion and directed energy deposition processes. In the latter case, closed-loop feedback is used to control melt pool temperature and cooling rate in order to achieve desired microstructure.

HABÁSKO Jakub: Optimalizace výrobního procesu. Diplomová práce navazujícího magisterského studia, 2. roč. šk. r. 2008/2009, FSI VUT v Brně, Ústav metrologie a zkušebnictví, říjen 2009, str. 68, obr. 40, tabulek 2, příloh 4. Projekt zpracovaný v rámci magisterského studia oboru Metrologie a řízení jakosti (3911T032) se zabývá optimalizací výrobního procesu. Na základě zadání byl zpracován rozbor současného stavu využívání statistických metod a zároveň byl proveden návrh vhodných metod aplikovatelných ve výrobní organizaci. Také je zde rozebrána problematika pájení zvonků, jelikož v tomto místě vzniká nejvíce netěsností. Dále práce přináší doporučení a závěry, které mohou přispět k optimalizaci tohoto procesu.

The incorrect slitting is the defect waste in slitting process which does not meet the single pack width and crease-to-edge width requirements. It is the highest contributor to the overall defect waste in slitting process at Company X Jurong (CXJ). To address this problem, the key input and output variables were identified. The inputs are the tension settings (both at main pull-unit and re-winder), line speed and knives’ positioning, and the output is crease-to-edge width. The objectives are to optimize the inputs and to achieve a centered process by a proper calibration of knives’ positioning. The Design of Experiments (DoE) was conducted to study the significance of tension and line speed towards crease-to-edge width variance for 200 mL slim pack size. The experiments were conducted for two fixed re-winder tension settings, i.e. 55% and 85%. The optimum point is found at pull-unit web tension of 1600 N and line speed of 700 m/min. This results in standard deviation of σ55%, min = 0.081 mm and σ85%, min = 0.09 mm, which is about half of each maximum variation values obtained within the specified range. However, the process is currently off-centered. Therefore, a proper training for detecting any mean shift happening in the process to the operators utilizing the digital camera measurement system is recommended.

At a certain point of its life cycle, each data warehouse gets into a state in which the length of the ETL processing starts slowly approaching the acceptable limit. Even the slightest lapse means a hardly erasable time lag and the data supplies to users are increasingly delayed. Before the situation becomes more problematic, we need to react. This diploma thesis deals with the possible solutions of this problem- the ETL performance optimization. The main aim of the thesis is to propose the set of recommendations for the ETL process optimization and its presentation based on practical real world examples. While going through this thesis, the readers get inside the running of the real ETL optimization project. They learn how to proceed during its particular periods, what to avoid and how to reduce the risk level as much as possible. Moreover, the thesis mentions the prevention of the ETL performance loss and discusses the critical factors of the effective ETL process design. Although the proposed methods are described in a general perspective, the thesis is mainly focused on Oracle's database, which is its certain limitation. Also hardware optimization is not a part of the text. First chapters of the thesis describe the problem from the theoretical point of view, which is important for the correct understanding of the main content and the existing literature concerning this problematic is included here as well. Next sections describe the proposed methods and recommendations for the optimization of the ETL processes including tests and project results evaluation. They are mainly focused on the ETL process synchronization and the SQL code optimization areas. All the methods are presented of examples of the real project implemented by the author.

Práce se zabývá analýzou výrobní linky z pohledu celkové efektivity. Cílem je definovat oblasti hrající roli v celkové efektivitě a následně vymyslet vhodné řešení k jejich zlepšení. Důraz je kladen na analytickou rozborovou metodu Basic MOST, podle které je stanoven normovaný čas operátorů. Další část je zaměřena na analýzu s cílem identifikovat slabá místa linky, jež lze optimalizovat za účelem zvýšení efektivity nebo dosažení finančních úspor. Výrobní linka a její analýza je také zpracovaná jako systém diskrétních událostí v programu Siemens Plant Simulation, kterým je také proveden návrh nového pracoviště. Posledním bodem práce je návrh konceptu digitálního dvojčete v programu Siemens NX, jenž je řízen simulovaným PLC.
