Background<\/span><\/h3>\n

A manufacturer is tracking the failures occurring in a product line. When a failure occurs in a machine, the time of occurrence and the time of repair are recorded for the machine and the parts that failed. Using Weibull++\u2019s event log folio, determine the failure and repair distributions.<\/p>\n

Experiment and Data<\/span><\/h3>\n

The machines operate 8 a.m. to 5 p.m. Monday through Friday. The time of occurrence and time of repair for the machine and parts that failed are shown in the following table.<\/p>\n<\/div>

Analysis<\/span><\/h3>\n

Step 1:<\/b> Add an event log folio to an existing project by choosing Insert > Folios > Event Log<\/b>. Once the folio is created, select the Use System column<\/b> option on the Other page of the control panel, as shown. This will allow you to identify the system that experienced each event<\/p>\n<\/div>

\"\"\/<\/div><\/div>
Step 2:<\/b> Enter the data from the above table into the data sheet, as shown next.<\/div>
\"\"\/<\/div><\/div>
\n

Step 3:<\/b> On the Main page of the control panel, select 1<\/b> from the System<\/b> drop-down menu. Enter January 1, 2004<\/b> for the Start Date and 8 AM<\/b> for the Start Time. Enter June 24, 2005<\/b> for the End Date and 5 PM<\/b> for the End Time. Make sure that the System is new on start date<\/b>option is selected, as shown in the previous figure, so the system will be considered new at the start of the analysis period.<\/p>\n

Step 4:<\/b> Repeat the previous step for system 2 using the same data.<\/p>\n

Step 5:<\/b> Click the Shift Pattern icon on the control panel and then set the shift pattern, as shown next.<\/p>\n<\/div><\/div>
