Question 20
In a manufacturing facility, the supervisor is interested in improving efficiency of the assembly line using sensor data. While the modern machines in the facility are able to provide automated data feeds at 1Hz frequency (i.e. one data point every second) over a standard Ethernet port, the older machines have a screen showing the digital readings but no data feeds. She therefore instructs the operators to jot down readings from the screen. Which of the following are possible challenges she will have to overcome?
Ethernet is not a suitable protocol for machine data and so, for the modernmachines too, it is best to have operators read from the screen and jot down manually.
The rate of 1Hz for data feeds is too fast for available streaming technologies.It is best to reconfigure the machines to produce at 0.5Hz or lower.
Manual data entry is prone to error and so she cannot trust the data for theolder machines blindly.
The rate at which operators are able to jot down the readings will not matchthe 1Hz frequency of automated data collection. So, she has to reconfigure the modern machines to produce at 0.1Hz or lower.
The number of operators doing only data readings would be significantlyhigher if she wants to collect data at a reasonable frequency for being useful to increase efficiency.
