Questions and Answers

What is the relationship between the model type and solution method in operations research?

  • The model type determines the solution method
  • They are both part of the operations research technique (correct)
  • The solution method determines the model type
  • They are independent of each other

    • When a mathematical model is solved, what does it imply about the associated problem?

  • The problem is partially solved
  • The problem is solved as well (correct)
  • The problem is not necessarily solved
  • The problem is represented more complexly

    • What is the meaning of the objective function in a mathematical model?

  • It aims to minimize the profit
  • It aims to maximize or minimize an outcome like profit (correct)
  • It represents the decision variables of the model
  • It represents the constraints of the model
