Model 1 (Steady-state)
Suppose the typical weekday is divided into a few distinct periods h = 1, …, H, each with constant flow Vh for a duration qh. With short-run variable cost given by equation (3.31), the resulting daily cost function is:
![]()
where V is the vector of flows Vh, q is the vector of durations qh, and ρ is the capital recovery factor52 divided by the number of weekdays per year. The first-order condition for minimizing (3.57), with K(VK) given by (3.56), gives the following investment rule:
![]()
The marginal capital cost of expanding the ...
