hello, i need to get answer to the question attached. thank you

rev: 02_06_2015_QC_CS- Problem 6-6 -2-2 http://ezto.mhedu Twelve tasks, with times and precedence requirements as shown in the following table, are to be assigned to workstations that have a fixed machine cycle time of 1.5 minutes. Two heuristic rules will be tried: (1) greatest positional weight, and (2) greatest number of following tasks. In each case, the tiebreaker will be shortest task time. Length (minutes) 0.1 0.2 0.9 0.6 0.1 0.2 0.4 0.1 0.2 0.7 0.3 0.2 Task a b c d e f g h i j k l Immediate Predecessor a b c d, e f g h i j k b. Assign tasks to stations under each of the two rules. (1) greatest positional weight (shortest task time as tiebreaker) Work Station Tasks I (Click to select) II (Click to select) III (Click to select) (2) greatest number of following tasks (shortest task time as tiebreaker) Work Station Tasks I (Click to select) II (Click to select) III (Click to select) c. Compute the percentage of idle time for each rule. (Round your answer to 2 decimal places. Omit the "%" sign in your response.) Percentage of idle time rev: 02_04_2015_QC_CS-1678 Problem 7-2 % rev: 0 Problem 7-2 -2-2 http://ezto.mhedu A job was timed for 60 cycles and had an average of 1.5 minutes per piece. The performance rating was 98 percent, and workday allowances are 10 percent. Determine each of the following: a. Observed time. (Round your answer to 1 decimal place.) minutes Observed time b. Normal time. (Round your answer to 2 decimal places.) minutes Normal time c. Standard time. (Round your answer to 2 decimal places.) minutes Standard time Problem 7-3 -2-2 http://ezto.mhedu A time study was conducted on a job that contains four elements. The observed times and performance ratings for six cycles are shown in the following table. OBSERVATIONS (minutes per cycle) Element 1 2 3 4 Performance Rating 90% 85 110 100 1 0.44 1.50 0.84 1.10 2 0.50 1.58 0.89 1.14 3 0.43 1.47 0.77 1.08 4 0.45 1.51 0.83 1.16 5 0.42 1.49 0.89 1.16 6 0.46 1.52 0.80 1.26 a. Determine the average cycle time for each element. (Round your answers to 3 decimal places.) Element Average cycle 1 2 3 4 b. Find the normal time for each element. (Round your answers to 3 decimal places.) Element Normal time 1 2 3 4 c. Assuming an allowance factor of 11 percent of job time, compute the standard time for this job. (Round your answers to 3 decimal places.) Element 1 2 3 4 Standard time
