Question
APPLICATION PROBLEMS tuation described in this problem is the filling of 10-ounce juice Ten different kinds of juice may be filled by a 12-headed filling machine weig hts from this machine have been erratic with many underweight Fill needing to be removed from the packaging line. A list of reasons for boxes variation in the fill weights is being developed, with the current list as follows within-head variation, between-head variation, the average fill from the machine may drift over time, juice is spilled as the boxes move along the conveyor belt prior to being sealed, the conveyor belt does not run at a constant speed; it may be slowed down or sped up, operators adjust the equipment if they believe the fill is too much or too little, e some juice types are more "pulpy" than others, and the same juice type may be more "pulpy" at some times than others. Three different sampling plans and subgroup structures are described. For each of the three, answer the following three questions: a. What sources of variation impact subgroup ranges? b. What sources of variation are reflected between subgroups? c. What learning objectives would be supported by this subgrouping plan? Subgroup Plan 1 Twice each shift, for 10 consecutive shifts, 12 boxes filled by a cycle. measure the net weight of the Subgroup Plan 2 Randomly choose five containers from the 12 filled during a cycle five net weights will form a subgroup. Collect one subgroup of 20 consecutive shifts. . The on each shiftExplanation / Answer
a)
Group1)we'll just be able to identify the overall variations that we come across in consecutive shifts.
2) we'll get variations in different types of juices as well as the error analysis would be accurate because of the number consecutive shifts we are analysing is more than that of the previous one.
3)we'll be able to analyse the consistency of different types of juices and also we can find out whether the problem is with the conveyor belt's speed or not.
b) 1)consistency of different cycles and problems in belt speed
2) problem in different heads and their operations.
3)problems in different heads and the texture and consistency of the juice filled in.
c) objectives of learning supported by these subgroup plan are that we'll learn to design techniques that helps us diagnose the actual problem in every process.
