Operations Research Flashcards
What is a model?
A model is a mathematical, graphical, or physical representation of an actual system.
A simplified version of a complex system.
what is Linear Programming?
Linear programming is a mathematical optimization technique used to find the best solution to a mathematical model with constraints.
It involves maximizing or minimizing a linear objective function while satisfying linear constraints.
What is operations research?
operations research is the study of man, machine, materials and time, to aid management decision
Objective function
An objective function is a mathematical expression that represents the goal or objective of an optimization problem.
In mathematical optimization, the objective function is the quantity that needs to be maximized or minimized to achieve the best possible outcome.
Decision Variables
Decision variables are the inputs or unknowns that a decision-maker or user must provide as input to the objective function in an optimization problem.
Constraints
constraints are the limitations or restrictions that an optimizer must adhere to when searching for the optimal solution.
Non-negative constraint
a non-negative constraint is a type of constraint that specifies that the values of the decision variables must be greater than or equal to zero. It restricts the decision variables from taking negative values and confines them to positive values or zero.
