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...

MAT 510 Midterm Exam (50 Questions and Answers) Why is it so difficult for a person or an organization to improve? A SIPOC map is: Problem solving activities typically include: Understanding variation is important because variation: Improvement is needed for an organization to survive because: In the soccer case study, Coach Hau developed a flowchart of the steps one goes through to properly “head” the ball, and then developed unique drills to develop the team’s skills in each of these st...

DESCRIPTION MAT 540 WEEK 8 CASE STUDY 2: IMPROVING E-MAIL MARKETING RESPONSE MAT 510 Week 8 Case Study 2 Use the data shown in the table to conduct a design of experiment (DOE) in order to test cause-and-effect relationships in business processes for the company. Determine the graphical display tool that you would use to present the results of the DOE that you conducted in Question 1. Provide a rational for your response. Recommend the main actions that the company could take in order to incr...

MAT 510 Week 7 Homework Assignment 6 The data in the table below is from a study conducted by an insurance company to determine the effect of changing the process by which insurance claims are …… The goal was to improve policy holder satisfaction by speeding up the process. And eliminating some non-value-added approval steps in the process. The response measured was the average time ….to approve and mail all claims initiated in a week. The new procedure was ….for 12 weeks, and the resul...

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...
