it helps in converting the verbal description and numerical data into mathematical expression

decision-makers prefer to work with formal models

it captures the relevant relationship among decision factors

it enables the use of algebraic technique

constrained optimization technique

technique for economic allocation of limited resources

mathematical technique

all of these

value of the objective function

value of a decision variable

use of the available resource

all of these

relationship among all variables is linear

it has single objective function and constraints

value of decision variables is non-negative

 all of the above

Is possible when the value of the variable is known 

reduces the scope of judgement and intuition known with certainty in decision making 

require the use of computer software

none of these

must be deterministic

represents data in numerical form

all of these

requires computer aid for its solution

an iconic model

an analogue model

a verbal model 

a mathematical model

provides the best decision

provides a decision within its limited context 

helps in evaluating various alternatives 

all of these

logical approach 

rational approach 

scientific approach 

all of these

sensitivity analysis

cost/benefit analysis

model validation 

input variation
