By a work sampling study: Observed Data The machine is being used Proportion of manual labour (machine is running and/or (servicing time) T-% machine is random serviced) Allowance Time Proportion of machine time T₂-% Tea time, Personnal time, Electrical shortages, etc.. Number of Observation 2000 597 Total No. of observations No. of units produced in 100 hours duration=-5000 units Observed rating factor = 120% 2597 Total allowances (PDF1 Style) = 23% of normal time Daily working hours-9hr/employee a) What % (p) of the time Machine is being used (machine time+servicing time) roughly? b) What is the absolute error(1) of the percent Machine is being used? (95% CI) c) What is the relative error of the percent Machine is being used? d) What is 95% confidence interval of working %? In sense of Relative and Absolute accuracy -both are asked!!!!- e) What is the actual production time (OT) taken per article (Attention:Be careful the observed time covers the service and machine time per article (OT) f) Calculate the observed manual labor time (means the service time) per article (Hint: Proportion of manual labour (servicing time) Tnw=14) g) Calculate the normal labour time (service time) per unit T you have calculated in f) h) Calculate the machine time per unit T. (Hint: Proportion of machine time T_=1/4) i) Calculate the Normal time per unit? j) Calculate the standard time (ST) per unit produced (Total allowances (PDF1 Style) -23%) k) What is the Standart Output for the one machine supervised by one operator with 100% performance (standart rating factor = 100%) for an 100-hour duration under the conditions described above? 1) What can be said about the operators performance rating when total of 5000 units were produced during 100hrs.
