13 ADDITIONAL FINDINGS OF FACT (FF)
14 We make the following additional enumerated findings of fact, which are
15 supported by at least a preponderance of the evidence.
16 Baum
17 11. Baum describes an approach to modeling labor resources, and
18 emphasizes techniques for modeling equipment breakdowns (Baum,
19 p. 448).
20 12. Baum portrays a chart that analyzes machine uptime against the
21 frequency of that uptime (Baum, Fig. 6, p. 452).
22 13. Baum’s analysis regards scheduled and unscheduled downtime and
23 relates the analysis to mean-time-between-failures and mean-time-to-
24 repair (Baum 449).
25 14. Time between failures is the time gap between the events of a machine
26 beginning operation and its subsequent failure. Mean-time-between-
