You can further break this equation down into:

ܣݒ݈ܾ݈ܽ݅ܽ݅݅ݐݕ =

൫(ܣݏݏ݁ݐ ݄ܵܿ݁݀ݑ݈݁݀ ܶ݅݉݁ െ ݈ܲܽ݊݊݁݀ ܦ݋ݓ݊ݐ݅݉݁ ) െ ܷ݊݌݈ܽ݊݊݁݀ ܦ݋ݓ݊ݐ݅݉݁൯

(ܣݏݏ݁ݐ ݄ܵܿ݁݀ݑ݈݁݀ ܶ݅݉݁ െ ݈ܲܽ݊݊݁݀ ܦ݋ݓ݊ݐ݅݉݁)

For example, at Advanced Manufacturing, John wanted to see his Overall Equipment Efficiency (OEE) for
last Friday’s evening shift on a production line he’s watching. He clicked the Line 1 Container in the Asset
Tree, clicked the OEE tab and generated a custom OEE report, setting the specific date, selecting the
Evening shift and selecting to group the report by hour. This displays the OEE figures for each hour in the
Evening shift.

Figure 9.7 Availability Example

CheckPoint™ calculated the Availability factor for each hour of the shift for the K2803-1 PW AC/DC 1000 SD
welder in Figure 9.7 using the data in Table 9.1 below . *
