P[DVO=1 | T, O, D]
P[DVL=1 | T, O, D]
FCR|T,O,D(cr|t,o,d) – a CDF of repair cost given T,O,D
CR = repair cost
CO&P = overhead & profit, ~U(0.15, 0.20)
j = index of assembly type
d = index of damage state
Nj,d = number of assemblies of type j in state d
Cj,d = unit cost to restore assemblies of type j from state d, ~LN(mCj,d, bCj,d)
TR,m = time to restore operational unit m
T0 = design, contracting, and mobilization time
Tj,d = time for one crew to restore one unit of assembly type j from state d, weeks.
nj,d = number of crews available
Nt = number of changes of trade
Tt = change-of-trade delay, weeks.
Makris will provide fragilities from top of list through fume hoods by 1 Dec.
Hutchison will provide others. Draft fragilities to be delivered by early to mid-December
