By a work sampling study: Observed Data No. of units produced in 100 hours duration = 5000 units Number of Observation Observed rating factor = 120% Proportion of manual labour (servicing time) Tw=74 Total allowances (PDF1 Style)= 23% of normal time The machine is being used (machine is running and/or machine is random serviced) 2000 Daily working hours=9hr/employee Proportion of machine time Tm= 14 Tea time, Personnal time, a) Allowance Time What is the relative error of the percent Machine is being used ? 597 Electrical shortages, etc., b) What is 95% confidence interval of working%? In sense of Relative and Absolute accuracy -both are asked!!!!- c) What is the actual production time (OT) taken per article (Attention:Be careful the observed time covers the service and machine time per article Total No. of observations 2597 (OT) d) Calculate the observed manual labor time (means the service time) per article (Hint: Proportion of manual labour (servicing time) Tnw=94) e) Calculate the normal labour time (service time) per unit Tnw you have calculated in f) f) Calculate the machine time per unit Tm (Hint: Proportion of machine time Tm= 14) g) Calculate the Normal time per unit? h) Calculate the standard time (ST) per unit produced (Total allowances (PDF1 Style)= 23% ) i) 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 ? i) What can be said about the operators performance rating when total of 5000 units were produced during 100hrs
