![]() ![]() On the other hand, you can also calculate the days in the week if you. Change the 21 to a cell reference of the number of weeks as desired. You can easily convert a date into the week number in Excel with the WeekNum Function. Look at the following OEE data for two sequential weeks. 3:00 am MONTH (DATE (YEAR (NOW ()),1,1)+217-1) converts 21 weeks to month 5, based on the current year. A single number that captures how well you are doing (OEE) and three numbers that capture the fundamental nature of your losses (Availability, Performance, and Quality). A positive value for days yields a future date a negative value yields a past date. The number of nonweekend and nonholiday days before or after startdate. In the preferred calculation, you get the best of both worlds. Syntax WORKDAY (startdate, days, holidays) The WORKDAY function syntax has the following arguments: Startdate Required. For example, use DATE (2008,5,23) for the 23rd day of May, 2008. Dates should be entered by using the DATE function, or as results of other formulas or functions. This is the role of Availability, Performance, and Quality. Syntax WEEKNUM (serialnumber, returntype) The WEEKNUM function syntax has the following arguments: Serialnumber Required. What your OEE score doesn’t provide is any insights as to the underlying causes of lost productivity. And it makes it easy to track improvements in that process over time. OEE scores provide very valuable insight – an accurate picture of how effectively your manufacturing process is running. And, as described earlier, multiplying Good Count by Ideal Cycle Time results in Fully Productive Time (manufacturing only Good Parts as fast as possible, with no Stop Time). This is the “simplest” OEE calculation described earlier. ![]() OEE = (Good Count × Ideal Cycle Time) / Planned Production Time ![]()
