DIN EN 614-2:2008-12 EN 614-2:2000+A1:2008 (E) 4 Introduction This European Standa

28、rd helps the designer in applying ergonomics principles to the design of machinery, focusing especially on the interaction between the design of machinery and work tasks. This is essential since the quality of design and safety of machinery depends on the prospective operators being able to perform

29、their tasks with the machinery in a safe and competent manner. Applying ergonomics principles to the design of machinery and work tasks aims at minimizing the discomfort, fatigue and other impairing effects faced by the operator and thus contributes to the optimal functioning of the work system (EN

30、292-2:1991, Annex A.1, 1.1.2 (d) and reduces the risks of negative health effects. Therefore, good design follows ergonomics principles, starts with the specification of system functions and anticipates how the prospective operator will interact with the machinery and other work equipment. In the de

31、sign of machinery and work tasks, the physical aspects of the operators activities are not the only design parameters to be dealt with. Operator activities also include the perception and processing of information, determination of strategies, decision making and communication. 1 Scope This European

32、 Standard establishes the ergonomics principles and procedures to be followed during the design process of machinery and operator work tasks. This European Standard deals specifically with task design in the context of machinery design, but the principles and methods may also be applied to job desig

33、n. This European Standard is directed to designers and manufacturers of machinery and other work equipment. It will also be helpful to those who are concerned with the use of machinery and work equipment, e.g. to managers, organizers, operators and supervisors. In this European Standard the designer

34、 refers to the person or group of persons responsible for the design. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are list

35、ed hereafter. For dated reference subsequent amendments to, or revisions of, any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies (including amendments). EN 61

38、 5 3 Terms and definitions For the purposes of this European Standard, the terms and definitions given in EN 614-1 apply. 4 Principles of work task design Work task design covers the analysis and specification of functions and their allocation to the machine or the operator as part of the design pro

39、cess, and aims at contributing to the optimal functioning of work systems. Therefore, good design follows ergonomics principles and gives special attention to the intended operator population. Principles of good ergonomic design are given in EN 614-1. The aim shall be achieved by approaching the cha

40、racteristics of well designed operator work tasks given in 4.1 by following the methodology for work task design given in 4.2 and by performing an evaluation of work task design according to 4.3. 4.1 Characteristics of well-designed operator work tasks When designing machinery and work tasks, the de

41、signer shall ensure that the following ergonomics characteristics of well-designed work tasks are fulfilled. These characteristics take into account the differences and dynamic characteristics of the intended operator population, and shall be pursued by designing machinery and work tasks in interact

42、ion. Thus, in the design process the designer shall a) recognise the experience, capabilities and skills of the existing or expected operator population. This includes the levels of general education and vocational training, as well as knowledge acquired in other similar working situations. It shoul

43、d be kept in mind that levels of training and knowledge vary across operator populations and change over time. Therefore, e.g. speed and complexity requirements and information on task performance should be adaptable to all intended users. b) ensure that work tasks to be performed are identifiable a

44、s complete and meaningful whole units of work with a clearly identifiable beginning and end, rather than as isolated fragments of such tasks. Therefore, each work task should in particular comprise not only performance components, but also preparatory (e.g. planning) and evaluative (e.g. inspection,

45、 checking) components. c) ensure that work tasks performed are identifiable as a significant contribution to the total output of the work system. The operator should be able to understand how and to what extent task performance and its outcome will affect the whole work system and its outcomes. Thus

46、, unnecessary fragmentation of the work process, leading to narrow operator work tasks shall be avoided. d) provide for the application of an appropriate variety of skills, capabilities and activities, and in particular provide for an appropriate combination of the following types of behaviour: skil

47、l based behaviour, which consists of an immediate, simple conscious or non-conscious reaction to cues from the work process, rule based behaviour, which allows the operator to exert control of the work process by applying basic algorithmic rules (e.g. by making simple if-then decisions) knowledge ba

48、sed behaviour, which requires the operator to develop and maintain a complex set of knowledge about the interrelationships in the process, in order to diagnose system states and faults, and to develop solutions and perform adequate actions. e) provide an appropriate degree of freedom and autonomy to

49、 the operator. The operator should be able to choose among alternative ways of task accomplishments and determine priority, pace and procedure of the work task. Rigidly fixed sequences, pace and working methods shall be avoided. DIN EN 614-2:2008-12 EN 614-2:2000+A1:2008 (E) 6 f) provide sufficient feedback on task performance in terms meaningful to the operator. Information on performance shall be made available enabling the operator to check whether goals are reached and performance is adequate. This includes also information on performance mist
