Question

4. What control chart would you use for one of the following situations and why1 a. The manufacture of corn syrup where raw materials enter a reactor on a continuous basis (400 gallons per minute). The finished syrup leaves the reactor after approximately 20 minutes of processing. b. A packing line of a specialized sugar process is as follows: Bags are filled to +1- 1 pounds, the bags are dropped onto a conveyor which takes them across a scale (in other words, each bag is weighed). The bags are then mechanically placed onto a pallet. Bags that are either under or over weight by 3lb are diverted and weight adjusted. A company makes machines. They have eight stations where very experienced laborers (all in excess of 15 years experience) perform final assembly of a critical component (the assembly has 85 parts). c. A window manufacturer is concerned about the condition of lumber as it comes to the factory. In particular the 3" by 12" wood (of varying length) seems to have a lot of imperfections. d.

Explanation / Answer

(a) In this example finished product leaves the reactor every 20 minutes which means one data point is collected at each point in time,

Here data type is continious.

We can use I-MR chart

(b) In this example also data is collected individualy for bag weight ie we are looking at measurement data for individuals which is also continious typr of data

we an use I-MR chart

(c) In this example data is collected for each of eight station to make the control charts. Here there are total eight stationwhich means we can have eight subgroups of data.

We can use Xbar-R chart in this situation

(d) As we can observe that from given example window manufacturer is concerned about defecets ofr imperfection in the lumbers, ie data is collected for different defects in lumbers.

data type : Descrete

Defects : Multiple

and sample size is contant we can use C chart
