The respiration of a tree is the sum of its maintenance respiration, R m, and its growth respiration, R g, a constant fraction of (GPP-R m ).
The annual investment costs (left( {dot{C}_{text{anu}} } right)) are the sum of equipment, maintenance, and annual fuel costs which is calculated by Eq. (44).
Mr. Glynn said the utility had always spent appropriate sums on maintenance, coming within one-half of one percent of the amount built into rates over a 20-year period.

The model results showed that the total workers' maintenance time (114,204.74 h) of Period 4 for overhaul maintenance activities was less than the sum of total workers' maintenance time for overtime (100,255.15 h) and rework (22,560.59 h) maintenance activities with about 8611.01 h (Table 7).
The amounts of total workers' maintenance time for Period 3 (101,905.72 h) was more than the sum of total workers' maintenance time for overtime (63,100.49 h) and rework (11,139.82 h) maintenance activities with about 27,665.41 h (Fig. 6).
R has been calculated as the sum of growth and maintenance components (respectively, Rg and Rm.
This is defined as the cost of one cubic meter of water applied to crops, and is the sum of investment (Ca), maintenance (Cm) and energy (Ce) costs.
These long-run marginal costs are the sum of the operation, maintenance and fuel costs and the initial investment expenses, the latter of which are annualized by means of a discount rate which can depend on the scenario used (the scenarios are described in the following section).
