Term
 Decision Variables
Definition
 variables whose values are under our control and influence system influence
Term
 Optimal Solution
Definition
 Any feasible solution that also optimizes the objective function
Term
 Objective Function
Definition
 Measure of reward (cost) that results from choice of decision variable values
Term
 Transpose of a Matrix (Example)
Definition
 [image]
Term
 Constraints
Definition
 limitations on the values of decision variables
Term
 Static v. Dynamic
Definition
 Static - decision variables don't involve sequences of decisions over time
Term
 Feasible Solution
Definition
 Any assignment of decision variables that satisfies ALL of the constraints
Term
 Deterministics v. Stochastic
Definition
 Deterministic - all problem parameters are known with certainty
Term
 Integer v. Noninteger
Definition
 Integer - decision variable must be integer valued
Term
 Linear v. Nonlinear
Definition
 linear - decision variables in the objective function and constraints are multiplied by constants and are added
Term
 Linear Function
Definition
 for some constants c1, c2,.....,cn we can always write the function as f(x1, x2,...., xn) = c1x1 + c2x2 +..... + cnxn
Term
 Parameters
Definition
 inputs to the model beyond our control
Term
 Multiplying Matrices
