Story of the Bedaux SystemIn 1911, Mr. Charles E. Bedaux experimented with the idea of measuring all human physical w

22、ork in terms of a common unit.The unit known as the Bedaux Unit of human power measurement or “B” was to consists of a combination of work and rest.The proportions between these two items were dependent upon the physical nature of the work and the subsequent rest required to compensate for it. As ta

23、sks varied, the ratio of the work to rest within the unit was to vary, but the unit itself was to remain constant at a time value of on minute.II. The Bedaux System or “E” System(Unit System)The “Unit E” is the quantity of work an experienced, skilled worker can do per minute under normal conditions

24、, taking into account the inherent allowance for rest, personal needs.III. The “M” System(Unit System)The Unit (M) is the amount of work that can be carried out in one minute by a trained worker, under normal circumstance, and at normal speed, including allowances for interruptions as rest and perso

25、nal care.The Unit (M) does not represent time in the sense of a clock time, but it is rather a measure of “work quantity” or “labor content”.IV. ExpressionWork Quantity or Labor Content = Work + Rest (Bedaux definition) or = Work + Total Allowance (Philips definition)Example: Labor Content 1M TAF-to

26、tal allowance factor: 1.14/ 1.18/ 1.2Labor Content Work (Normal Time) TAF1M (60 seconds) = 52.6 seconds + 7.4 seconds (14 %)1M (60 seconds) = 50.8 seconds + 9.2 seconds (18 %)1M (60 seconds) = 50.0 seconds + 10.0 seconds (20 %)VIII. Performance RatingPerformance rating is expressing numerically the

27、speed and effectiveness with which an operation is done, in relation to what has been defined as normal performance.Tempo means the intensity of working.In Bedaux time-study system: Speed of the movementsTempo Skill of the movements (i.e. proficiency, useful effect, dexterity, efficiency).IX. Normal

28、 PerformanceNormal performance is the performance of an average skilled worker doing a job under normal conditions without being stimulated by an incentive scheme.It must be possible to keep this performance from day to day without excessive physical or mental strain.As a reference for normal perfor

29、mance can be taken, a steady deliberate and unhurried average performance of a person, who walks around 4.8 Km(3 miles) per hour or deals 52 playing-cards in 30 seconds.X.
