Question
As an aircraft technician, we would routinely install parts just to learn at a later time that the part was defective. When this happens, hours of manpower as well as U.S. taxpayer money is wasted during the process of diagnosing, removing the part, reordering the part, waiting for the part to arrive, reinstalling it, then retesting. As a flight line technician, it is very difficult to diagnose problems within the parts once they are installed, especially the electrical components such as computers, throttle modules, etc. Also, once the parts reach the suppliers from the manufacturer, they are not tested at all, although they are insulated from outside forces that may damage them. An NP control chart would help both the supply warehouse and the flight line technicians diagnose defective parts early in order to save a tremendous amount of resources if a part happens to be defective. What chellaneges may he has using the NP control chart and what can he substitiute with and why? Discuss briefly
Explanation / Answer
ANSWER:-
NP control chart:-
An np control chart is used to look at variation in yes/no type attributes data. There are only two possible outcomes: either the item is defective or it is not defective. The np control chart is used to determine if the number of defective items in a group of items is consistent over time.
chellaneges in using NP cntrol chart in aircraft technology:-
Control charts are used to monitor the output of a process over time to determine whether or not the process is stable and exhibiting common cause variation, or unstable and exhibiting special cause variation
Prior to collecting data, stratification should be considered
how much of the available data to use and which control chart to use. The type of control chart that you should use under a given set of circumstances can be determined by using the following decision flowchart. In this chart, n refers to size of the subgroup of data that will be selected from each time period
substitiute he can do in np contrl chart in aircraft:
Choose the appropriate control chart for your data.Determine the appropriate time period for collecting and plotting data.Collect data, construct your chart and analyze the data.Look for “out-of-control signals” on the control chart. When one is identified, mark it on the chart and investigate the cause. Document how you investigated, what you learned, the cause and how it was corrected
hence this the using np cntrol chart in aircraft technolgy challenges and substitution
