MAT 540 Final Exam In an unbalanced transportation model, supply does not equal demand and one set of constraints uses ≤ signs. In a transshipment problem, items may be transported from destination to destination and from source to source. Adjusted exponential smoothing is an exponential smoothing forecast adjusted for seasonality. A cycle is an up and down movement in demand that repeats itself in less than 1 year. If we are solving a 0-1 integer programming problem, the constraint x1 = x2 i...

MAT 540 Final Exam If we are solving a 0-1 integer programming problem, the constraint x1 = x2 is a conditional constraint. In a total integer model, all decision variables have integer solution values. In a transshipment problem, items may be transported from destination to destination and from source to source. Validation of a simulation model occurs when the true steady state average results have been reached. Excel can be used to simulate systems that can be represented by both discrete and...
