Operations Research or Qualitative Approach MCQ Questions and Solutions with Explanations | Management

The quantitative approach to decision analysis is a scientific approach. In quantitative decision analysis, we use scientific methods to inform the decision-making process. These methods help data scientists put a value to several critical pieces of information, which include the: Problem facing the organization.

Operations Research approach is typically based on the use of Mathematical model. A mathematical model is an abstract model that uses mathematical language to describe the behaviour of a system.

In a manufacturing process, Production manager takes the decisions as to what quantities and which process or processes are to be used so that the cost is minimum and profit is maximum. Production managers ensure that manufacturing processes run reliably and efficiently. Responsibilities of the job include: planning and organising production schedules.

For analyzing a problem, decision-makers should study both its qualitative aspects and Its quantitative aspects.

A model is an essence of reality an approximation and an idealization.

Managerial decisions are based on an evaluation of quantitative data, the use of qualitative factors and results generated by formal models.

The initial solution of a transportation problem can be obtained by applying any known method. However, the only condition is that the rim conditions are satisfied.

The dummy source or destination in a transportation problem is added to satisfy rim conditions.

Degeneracy in a transportation problem occurs when there are fewer independent allocations than required, i.e., fewer than (m + n - 1), where m is the number of rows and n is the number of columns.

Option A: "Total supply equals total demand" is a necessary condition for feasibility but does not define degeneracy.

Option B: "The solution is not feasible" is incorrect because degeneracy does not automatically lead to infeasibility. A valid solution can still exist despite degeneracy.

Option C: "The few allocations become negative" is also incorrect because negative allocations are not allowed in a transportation problem. This would indicate an infeasible solution, which is unrelated to degeneracy.

Therefore, the correct answer is Option D: None of the above, as none of the options accurately describe degeneracy. Degeneracy specifically refers to having too few independent allocations, which complicates the solution process but does not inherently make it infeasible.

An alternative optimal solution to a minimization transportation problem exists whenever opportunity cost corresponding to unused route of transportation is Positive with at least one equal to zero.
