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...

MAT 540 Week 2 Homework Chapter 12 (New Data) 1. A local real estate investor in Orlando is considering three alternative investments: a motel, a restaurant, or a theater. Profits from the motel or restaurant will be affected by the availability of gasoline and the number of tourists; profits from the theater will be relatively stable under any conditions. The following payoff table shows the profit or loss that could result from each investment: Gasoline Availability Investment Shortage Stable...

Process improvement activities typically include: A manufacturing process has been experiencing problems. The operators charting the process data have identified the cause to be due to an unanticipated change in incoming raw materials. This problem should be considered: Sub-optimization occurs when: Service processes are different from manufacturing processes in that: The Problem Solving Framework begins with a “Document the Problem” phase. The Process Improvement Framework does not begin ...

MAT 540 Final Exam Fractional relationships between variables are not permitted in the standard form of a linear program. In an unbalanced transportation model, supply does not equal demand and one set of constraints uses ≤ signs. Excel can be used to simulate systems that can be represented by both discrete and continuous random variables. In a transshipment problem, items may be transported from destination to destination and from source to source. In a total integer model, all decision var...

MAT 540 Final Exam The linear programming model for a transportation problem has constraints for supply at each source and demand at each destination When the right-hand sides of 2 constraints are both increased by 1 unit, the value of the objective function will be adjusted by the sum of the constraints’ prices. The standard form for the computer solution of a linear programming problem requires all variables to the right and all numerical values to the left of the inequality or equality sig...

MATH 225N Week 1 Assignment Comparing Sampling Methods Q & A A television station plans to send a crew to a polling center on an election day. Because they do not have time to interview … each individual voter, they decide to count voters leaving the polling location and ask every 20th voter for an interview. What type of sampling is this? In order to study the shoe sizes of people in his town, Billy samples the population by dividing the residents by age and randomly … selecting a proporti...
