The Excel Solver can issue all the following reports except:

a$)$ Answer Report

b$)$ Sensitivity Report

c$)$ Breadth Report

d$)$ Limits Report

True or False Infeasibility is a condition that arises when no solution satisfies all of the LP problem constraints?

True or False $-$ The feasibility region contains points which satisfy all constraints but may not be the optimal solution?

True or False The most common type of Linear Programming Problem is the product mix or relative inventory size problem.

Constraints that MUST be included in an Excel Solver setup if they exists, except:

a$)$ Product or Component mix constraints

b$)$ Redundant constraints

c$)$ Non$-$negativity constraints

d$)$ Time limit constraints

We may need to look at the Answer Report and$/$or Sensitivity Report for all these reasons, except:

a$)$ In the real world things are often dynamic and changeable

b$)$ One or more products or components may have suffered a price change

c$)$ An optimal solution could not be resolved

d$)$ There has been a change in available resources

e$)$ "What$-$if$"$ analysis and justification for projects to make changes

Forecasting

$15.$ True or False Every forecast problem should include error calculations to assess best fit.

$16.$ Which of the following is usually the best determination of the error in a forecast?

a$)$ Lowest MAD

b$)$ Highest MSE

c$)$ MAPE in general

d$)$ Lowest MAPE

e$)$ Highest raw error

$17.$ True or False The most common forecasting problem is inventory or demand.

$18.$ For a $N-$period moving average forecast, the first error calculation:

a$)$ Should be assumed

b$)$ Should begin in the $N$ period

c$)$ Should begin in the $N+1$ period

d$)$ Should be $0$

$19.$ True or False For an exponential smoothing forecast, the period one value is always $0$ and the error is also $0.$
