The work of preparing Int

18、ernational Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison w

19、ith ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of techni

20、cal committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn

30、ts rservs viiIntroduction Design of experiments (DOE) catalyses innovation, problem solving and discovery. DOE comprises a strategy and a body of methods that are instrumental in achieving quality improvement in products, services and processes. Although statistical quality control, management resol

31、ve, inspection and other quality tools also serve this goal, experimental design represents the methodology of choice in complex, variable and interactive settings. Historically, design of experiments has evolved and thrived in the agricultural area. Medicine has also enjoyed a long history of caref

32、ul experimental design. Industrial settings particularly benefit from the methodology due to the ease of initiating efforts (user-friendly software packages), improved training, influential advocates, and accumulating successes with experimental design. Design of experiments is fundamental to contin

33、uous improvement and product development. Experimentation often evolves sequentially with improvements taking place following each stage of the learning process. If the objective is to optimize a response, then response surface designs (3.2.19) play a critical role. Multiple levels of factors recogn

34、ized to be important are considered to accommodate neatly curvilinear effects, for example in the vicinity of the optimum settings. Factorial experiments (3.2.1) and fractional factorial experiments (3.2.3) provide a methodology for studying the interrelationships among multiple factors of interest

35、to the experimenter. These types of experiments can be far more resource efficient and effective than intuitive one-factor-at-a-time experiments. Factorial experiments are particularly well-suited for determining that a factor behaves differently (as reflected in the experimental response) at differ

36、ent levels of other factors. Frequently, the “breakthrough” in quality comes from the synergism revealed in a study of “interactions” (3.1.17). If the number of factors under consideration is large, then factorial experiments could exceed resources. However, fractional factorial experiments offer a

37、possible compromise. Actually, if the initial goal is to identify factors warranting further investigation, then screening designs (3.2.8) can be useful. In planning an experiment, it is necessary to limit biases introduced by the experimental conditions or in the assignment of treatments to experim

38、ental units. Topics such as “randomization” (3.1.30) and “blocking” (3.1.26) deal with minimizing the effects of nuisance or extraneous elements. Specific blocking strategies include randomized block designs (3.2.10), Latin square designs (3.2.11) and variants, and balanced incomplete block designs

39、(3.2.14). Designs for experiments with mixtures mixture designs (3.2.20) apply in situations where factors constitute proportions of a total, such as ingredients in an alloy. Nested designs (3.2.21) are particularly useful in inter-laboratory testing and in measurement system analyses. Methods of an

40、alysis of the collected data are straightforward, if the experiment has been carried out according to the plan. Graphical methods (3.3.1) can be particularly effective in revealing overall conclusions. Estimation of parameters from a model is commonly handled using regression analysis (3.3.7). Regre

41、ssion analysis methods can also handle difficulties with missing data, identification of outliers, and other problems. Annex A provides associated Concept Diagrams that relate the various terms. To assist users of this part of ISO 3534, an explanation of Concept Diagrams is provided in Annex B. Desi

42、gn of experiments consists of a complex process to implement experimental plans (3.1.29). Annex C provides checklists that are intended to identify key items to be considered in designing and implementing a designed experiment (3.1.27). Annex D describes experimental design from the systems model pe
