The Sensitivity of a Water Distribution System to Regional State Parameter Variations

Table 1

Different types of sensitivity analysis ordered from most to least complex.

	Which state parameters change? p = parameter(s), m = multiple, s = single	Cor	Max	Number of modifications	Results that apply	R
A	All p individually	No	1	All	None	m
B	All p of a type individually	No	1		1, 6	m
C	P of a type in m regions	Yes	>1	>1	7, 8
D	All p of a type in a s region	Yes	>1	1	5	s
E	P of a type in a s region	Yes	>1	1	1, 2	s
F	One p individually	No	1	1	3, 4

The first column labels the category. The column “Cor” indicates whether state parameters are correlated in a specific way. The column “Max” indicates the maximum number of parameters that change in the same way. The column “Number of modifications” indicates the number of different modifications that are made to parameters, e.g., if there are two parameter regions in which change is made, there are two modifications. refers to the number of parameters that exist of a specific type. The enclosed boxes under “Results that apply, R” can apply to multiple categories. The column “R” indicates the number of parameter regions.
