Applied Operations Research Challenge

What is the objective of linear programming?

• To find the maximum value of a nonlinear function without constraints.

• To minimize a quadratic objective function under nonlinear constraints.

• To solve systems of equations without any optimization.

• To optimize a linear objective function subject to linear constraints.

Which method is commonly used to solve linear programming problems?

• Dynamic programming

• Graphical method

• Simplex method

• Integer programming

In a network flow problem, what does the term 'flow' refer to?

• The maximum capacity of a network's bandwidth.

• The speed at which data is processed in a network.

• The total number of nodes in a network.

• The quantity of a resource being transferred in a network.

What is the primary goal of simulation techniques in operations research?

• To model and analyze complex systems for better decision-making.

• To simplify operations by reducing costs.

• To eliminate the need for data analysis.

• To create random outcomes without any purpose.

Which of the following is a key characteristic of CPM?

• Focusing solely on resource allocation.

• Ignoring task dependencies in planning.

• Emphasizing team communication over scheduling.

• Identifying the critical path in project scheduling.

What does PERT stand for in project management?

• Project Evaluation and Review Technique

• Program Evaluation and Review Technique

• Program Evaluation and Resource Technique

• Project Evaluation and Resource Tool

In the North West Corner method, what is the first step?

• Allocate to the last row of the cost matrix.

• Allocate to the top-left cell of the cost matrix.

• Allocate to the bottom-right cell of the cost matrix.

• Allocate to the middle cell of the cost matrix.

What is the purpose of the simplex method in linear programming?

• To identify all feasible solutions of a linear programming problem.

• To convert a linear programming problem into a non-linear one.

• To minimize the number of variables in a linear programming problem.

• To find the optimal solution of a linear programming problem.

How do you determine the critical path in CPM?

• The critical path is determined by the number of tasks in the project.

• The critical path is the shortest path through the project network.

• The critical path is the path with the least amount of resources used.

• The critical path is the longest path through the project network, determining the shortest time to complete the project.

What is a dummy activity in PERT analysis?

• A dummy activity is a real task that contributes to project completion.

• A dummy activity is a task that requires resources but no time.

• A dummy activity is a placeholder for a future task that consumes time.

• A dummy activity in PERT analysis is a representation of a dependency that does not consume time or resources.
