Operations Research MCQs

✅ The correct answer is option A.
Maximization of objective function in an LP model means Value occurs at allowable set of decisions. Linear programming refers to choosing the best alternative from the available alternatives, whose objective function and constraint function can be expressed as linear mathematical functions.

✅ The correct answer is option A.
Any column or raw of a simplex table is called a vector. The simplex method, in mathematical optimization, is a well-known algorithm used for linear programming.

✅ The correct answer is option B.
While assigning random numbers in Monte Carlo simulation, it is Necessary to develop a cumulative probability distribution. A cumulative probability refers to the probability that the value of a random variable falls within a specified range. Frequently, cumulative probabilities refer to the probability that a random variable is less than or equal to a specified value.

✅ The correct answer is option B.
Key concept under Network Analysis are network of events and activities , resource allocation, time and cost considerations, network paths and critical paths. Network analysis is any structured technique used to mathematically analyze a circuit (a “network” of interconnected components).

✅ The correct answer is option C.
Analytical results are taken into consideration before a simulation study so as to Identify suitable values of decision variables for the specific choices of system parameters. A true analytical result presumes an analytical procedure without systematic errors. They can be detected by comparing the analytical results with the true value or with an accepted reference.

✅ The correct answer is option B.
The solution need not be in whole numbers.

✅ The correct answer is option D.
In designing queueing systems we need to aim for a balance between service to customers (short queues implying many servers) and economic considerations (not too many servers).

✅ The correct answer is option B.
Every LPP called the primal is associated with another LPP called dual. Either of the problems is primal with the other one as dual.

✅ The correct answer is option D.
Linear programming is a mathematical technique for solving constrained maximization and minimization problems when there are many constraints and the objective function to be optimized, as well as the constraints faced, are linear (i.e., can be represented by straight lines).

✅ The correct answer is option C.
The transition matrix elements remain positive from one point to the next. This property is known as Regular property. A transition matrix (stochastic matrix) is said to be regular if some power of T has all positive entries.
