Document Summary

Requires observers to study two or three operations over a long time. Duration and reason for idle time are recorded, findings are then summarized to determine the percent allowance for each applicable characteristic. Beneficial when the process takes place in an area where lengthy studies can take place (ie. plant) Taking a large number of random observations (requires only part-time intermittent services of the observer) No stopwatch used, observers walk through area at random times and take notes. T=time require perform operation at end of continuous work t=time required to perform operation at beginning of continuous work. Show how log log functions and semi-log functions may be used to linearize standard data curves. Accuracy may be lost and computer software may be needed. Log-log function uses log units on x and y axis to make it linearized. The formula does not have expected validity: explain in detail how one would develop a best-fit formula using regression analysis based upon the.
