Learning curve was represent as common sense which was first created by a German psychologist Hermann Ebbinghaus as he states that the principle of learning curve shows a rate of improving a task in perform in a function of time (Ebbinghaus, 1850-1909). The main purpose of it is to study on the effect of the memory which relates to the performance that the memory can retain. Not only was that but, by the theory model developed by T.P Wright in 1936 which refer as the Wrights Model. Learning curve theory is based on the principle on the required time that involve on the workforce of any activity, process or job that begin for the first time will not be able to achieve the maximum speed straightaway. According to (Wright, 1936) , the average cumulative direct labor for an airplane to construct on production line will decrease in a foreseeable pattern. The amount of time will decline…show more content…
Therefore the formula is as for: 1 unit = 100 ×1 (log⁡0.8)/log⁡2 = 100. However, as for 2 unit = 100 ×2 (log⁡0.8)/log⁡2 = 80 The data continue to as it using the same formula repeatedly. Using logs to compute the curve allow to determine the hours needed for any unit that are produce. The constant decrease by percentage of the cost is known as the rate of learning. The slope in the diagram below (Figure 1.2b) is minus the rate of learning. For instance, if the time between the cumulative quantities reduce by 20%, it will give a curve slope of 80% slope. Wrights model would decrease 50% every time an output being doubled, as a result the cumulative total time will not increase due to the old data cumulative was 100% at a time (Liao, 1988) .
