JOURNAL FREE ACCESSIn the practical situation to analyze the reliability of a man-machine system, the analyst's considerations in a way to build up the system model, to evaluate the interdependencies among events and to judge the various error rates may effect on the result of the analysis, more than the case of hardware system analysis. Therefore, as a method for reliability analysis, it is necessary that the process and the basis of an analysis can be clearly shown to the third person as well as the analysis itself car be performed precisely.
In such a point of view, we intend to develope a new method for reliability analysis. In this article we describe the relation between our intention and a project of United States Nuclear Regulatory Commission, and the frameworks of our method. Next, we show a simple example of application and discuss about our approach, comparing with THERP as a classical method for human reliability analysis.View full abstractDownload PDF (1515K) -
Effect of depth between the objectsNaokuni EBIHARA1982 Volume 18 Issue 2 Pages 97-102
Published: April 15, 1982
Released on J-STAGE: March 11, 2010
JOURNAL FREE ACCESSThe effect of depth on the reaction time of size comparison was experimentally investigated. Subjects made “same” or “different” judgments on the objective size of two luminous rectangles presented in a dark room. The significant finding was that correct reaction times increased linearly with increase in depth between the two rectangles. Possible sources that might yield such a result were theoretically examined. Consequently, the result was explained by means of the time for the operations of accommodation and vergence eye movement necessary for fixating the eyes at the appropriate point in space. The reason was that these operations require more time as the depth between two objects increases. The present result is clearly different from that of the similar experiment carried out in a lighted room by other investigators. The difference seems to stem from the unusual formation of cues to distance in the dark.View full abstractDownload PDF (792K) -
work load under various pace conditions based on PTSKohki MIKAMI, Masaharu KUMASHIRO1982 Volume 18 Issue 2 Pages 103-110
Published: April 15, 1982
Released on J-STAGE: March 11, 2010
JOURNAL FREE ACCESSThe purpose of this study was to investigate work load under various pace conditions in repetitive work with difficulty concerning sight and hand movements connected with sight in terms of psychophysiological function and human performance. Pace conditions were based on PTS, and subjects were 6 healthy men. The task was performed by putting beads in the holes the places and colors of which were arranged. The experimental period lasted for 120min at the MTM pace of conveyers (I), for 120min at the WF pace (II), for 138min at the ‘MTM×1.15’ pace (An allowance of 15% was included) (III), for 96min at the WF pace (IV) and for 120min at the self-pace (V).
The results obtained were as follows:
1) In tasks (II) and (IV), the physiological function greatly lowered compared with that in the others, the frequencies of the complaints of subjective symptoms increased and the performance was found to be less efficiently performed.
2) In task (V), the physiological function did not lower significantly. However, compared with task (I), the frequencies of the complaints of subjective symptoms and the subsidiary behaviors increased and the performance was found to be less efficiently performed.
3) The frequencies of the complaints of subjective symptoms, the subsidiary behaviors and the defective articles of task (I) decreased most of all. The amount of the finished products most increased with that of task (III).View full abstractDownload PDF (1176K) -
