Quality Engineering in Manufacturing Technology
Tadeusz Sałaciński
This monograph talks about widely understood quality engineering problems, mainly in technological processes. It presents the theoretical background, as well as practical examples of tools, techniques and methods supporting supervision and improvement of quality of production processes, such as control charts, process quality capability indexes, and many others. Modern manufacturing technologies are key to obtaining highest product quality. Meeting very high requirements of customers is a diffi cult task faced by present manufacturing companies. This entails the necessity to use methods like MSA, SPC, FMEA, QFD, Six Sigma and others. Current literature on this subject is not consolidated and very dispersed. The proposed monograph is a culmination of the author's many years of work in the fi eld of production process engineering and in a comprehensive way discusses the use of a wide range of techniques, tools and methods in solving very complex problems. This work is a monograph; nevertheless, it may be used as an academic textbook at technical, economic and agricultural universities. For example, at the Warsaw University of Technology, it may be used as a reference publication for subjects such as Quality Management, Manufacturing Processes Quality Improvement, SPC - Statistical Process Control or Metrology, for fi elds of study like Management and Production Engineering, Mechanics and Mechanical Engineering, Automation and Robotics, Papermaking and Printing, with approximately 400 students. This publication may also be used by manufacturing companies - mainly from the mechanical industry, including machine tool building, automotive and aerospace industries. It may also be useful in other industry branches such as food processing, pharmaceutical industry and many others.
Jurek Sawka
Quality Time to pierwsza powieść reżysera teatralnego Jurka Sawki, który w 1969 roku wyemigrował do Sztokholmu, gdzie mieszka do dziś. W tej pełnej ironii, melancholii i czarnego humoru autofikcji przeszłość w Polsce oświetla teraźniejszość w Szwecji i na odwrót. Tragiczna historia Żydów przeplata się tu z satyrą na współczesną cywilizację, konsumpcjonizm, rozpad więzi społecznych. To także czuła i namiętna historia o ojcostwie, miłości do młodszej kobiety, umieraniu; o skazanej na niepowodzenie walce, by rzeczywistość dała się oswoić. Głównego bohatera powieści poznajemy w weekend, który spędza w swoim sztokholmskim mieszkaniu z córką i dwoma synami. Ma to być tzw. quality time, ale rozwiedziony mężczyzna widzi całą absurdalność tego fenomenu wie, że nie da się zrekompensować nikomu straconego wcześniej czasu. Mimo to czuje się zobligowany, żeby jak najlepiej zająć się dziećmi i zapewnić im rozrywki. Ostatecznie kończy się to tak, jak w wielu innych rodzinach: wspólnym gapieniem się w telewizor, graniem na komputerze, wypadem do McDonalda, wycieczką na basen i do supermarketu. Chociaż rodzina wie, że ten weekend jest po to, aby mogli pobyć razem, schodzą sobie z drogi i każde z nich zajmuje się swoimi sprawami nawet oglądanie meczu w tym samym pokoju odbywa się tak, że bracia oglądają dwa różne mecze, każdy na własnym ekranie. W międzyczasie główny bohater odpływa, oddając się rozmyślaniom na temat związku z dużo młodszą kobietą, wspomina swoje dzieciństwo w powojennym Kłodzku i pierwsze lata spędzone na emigracji. Jurek Sawka, którego życiorys ma wiele punktów stycznych z biografią Macieja Zaremby Bielawskiego, autora popularnego w Polsce reportażu Dom z dwiema wieżami, napisał książkę zgoła inną od tej ostatniej, choć osadzoną w podobnej osobistej historii. Quality Time różni się nie tylko dlatego, że jest powieścią; odmienne jest przede wszystkim uformowanie głównego bohatera i jego usytuowanie w świecie. Nie ma tu próby rekonstrukcji kroniki rodzinnej, za narratorem nie stoją bowiem dumne duchy przodków wywodzących się w jednej linii z żydowskiej inteligencji, a w drugiej z herbowej szlachty. Mama, lekarka, przyszła na świat w rodzinie biednego żydowskiego kapelusznika, ojciec, inżynier, był owocem gwałtu czeskiego ziemianina na wiejskiej służącej. W prowincjonalnym miasteczku żyli jak bieda-inteligencja: bez biblioteki pełnej książek, bez formy i bez rytuałów innych niż popijawy w towarzystwie kolegów ojca z pracy. Kapitał, jaki nasz bohater otrzymał od swoich rodziców, był niewielki. Ojca wspomina tak: Dzień w dzień po pracy tata siedział na zielonym tapczanie w naszym ciasnym mieszkaniu we Wrocławiu, pił koniak z małej butelki, którą buchnął z jeszcze jednej bezsensownej narady, i mamrotał: Po chuj żyć? Tę mantrę, sto pięćdziesiąt cztery polskie złote i radziecki zegarek odziedziczyłem w spadku. Mantrą zarządzam aż za dobrze, pieniędzy nie dało się wymienić, a okres gwarancji zegarka minął dawno temu. Sawka w swojej książce dokonuje bezpardonowej wiwisekcji psyche człowieka walczącego z depresją, brakiem przystosowania do fasadowego, szwedzkiego społeczeństwa, poczuciem obcości wobec własnych, wychowanych w diametralnie innej kulturze dzieci, doświadczeniem alienacji w ogóle zawsze i wszędzie, niezależnie od okoliczności. Emigracja nie jest w tej książce wyjazdem z kraju dzieciństwa, pozostawianiem ojczyzny, opuszczeniem rodziny gdyż te pojęcia w życiu bohatera nigdy się nie urzeczywistniły. Wychodźstwo, zdaje się mówić Sawka, to permanentny stan duszy. Kryje się w tej książce odwaga spojrzenia na wskroś bez upiększeń, ładnych słówek i poetyckich obrazów na życie w całej jego nudnej powtarzalności, na pustkę, którą zapełniają nam, liczne w dzisiejszej kulturze, czasoumilacze. Ale jest też w niej żar uczucia, które sprawia, że przynajmniej najbliższym chcemy ten czas tu i teraz uczynić znośnym.
