GATE CSE 2015 | Set 2 | Question: 12

Question

Consider the basic COCOMO model where $E$ is the effort applied in person-months, $D$ is the development time in chronological months, $KLOC$ is the estimated number of delivered lines of code (in thousands) and $a_b, b_b, c_b, d_b$ have their useful meanings. The basic COCOMO equations are of the form

• A. $E=a_b (KLOC) exp(b_b), D=c_b(E) exp(d_b)$
• B. $D=a_b (KLOC) exp(b_b), E=c_b(D) exp(d_b)$
• C. $E=a_b exp(b_b), D=c_b (KLOC) exp(d_b)$
• D. $E=a_b exp(d_b), D=c_b (KLOC) exp(b_b)$

Answer 1

Answer: A

In basic COCOMO model,

Effort Applied, E = a*(KLOC)^b
Development Time, D = c*E^d
People Required, P = E/D

where KLOC = Estimated number of delivered lines in thousands and a,b,c,d depends upon the software being Organic, Semi detached or Embedded.

Answer 2

COCOMO Model stands for Constructive Cost Estimation Model widely used in software engineering. 

If E is the effort applied in person-months, D is the development time in chronological months, KLOC is the estimated number of delivered lines of code (in thousands) and a_b,b_b,c_b,d_b have their useful meanings. The basic COCOMO equations are of the form

_^E =a_b(KLOC)exp(b_b), D=c_b(E)exp(d_b)
