Calculating Tracking Transactions per minute

Each time the location of a unit moving down the production line is tracked by the Youtilize system,

a tracking transaction is recorded in the Youtilize database. Tracking transactions are typically

generated by the workstations specified in your line definition. However, X45, X46, and other

functions may also be optionally configured to generate tracking transactions, so these must be

accounted for as well in your calculations.

The calculation itself is very straightforward. The goal is to determine how many transactions per

minute will be recorded across the entire line. This is done by multiplying the total number (N) of

workstations and/or tracking functions with the line production rate in units per minute.

For example, consider a line with 10 workstations and 3 tracking functions. The line operates at 600

units per hour, or 10 units per minute. The transaction rate would be calculated as follows:

(10 workstations + 3 tracking functions) * 10 units per minute = 130 Transactions per minute

Parallel Processing Workstations Treated as Single Workstation

One very important consideration is that parallel processing workstations may be treated as one

single workstation in your calculation. This is because the transaction rate of workstations in this

configuration is slower than the actual line rate. Only as a whole do they generate tracking

transactions as the line production rate. Consider the following example:

In this example, the 3 workstations in parallel configuration have a total effective throughput equal

to the line production rate. Therefore, they may be treated as one (1) single workstation in your

load calculation. So, for this line, rather than using 5 total stations, you would use 3 instead (Station

1 + (Station 2-4 cluster) + Station 5 = 3 effective stations). Therefore, the transaction rate would be

as follows:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 ... 124 125
