Is my solution correct and did I fully answer the questions? (see attachment for my solution) Question: There are three factories on Momiss River. Each emits two types of pollutants, labeled P1 and P2, into the river. If the waste from each factory is processed, the pollution in the river can be reduced. It costs $1,500 to process a ton of factory 1 waste, and each ton processed reduces the amount of P1 by 0.10 ton and the amount of P2 by 0.45 ton. It costs $2,500 to process a ton of factory 2 waste, and each ton processed reduces the amount of P1 by 0.20 ton and the amount of P2 by 0.25 ton. It costs $3,000 to process a ton of factory 3 waste, and each ton processed reduces the amount of P1 by 0.40 ton and the amount of P2 by 0.50 ton. The state wants to reduce the amount of P1 in the river by at least 125 tons and the amount of P2 by at least 175 tons. a. Use Solver to determine how to minimize the cost of reducing pollution by the desired amounts. Are the LP assumptions…
One possible solution method for the machine-to job assignment problem is the following heuristic procedure. Assign the machine to job 1 that completes job 1 quickest. Then assign the machine to job 2 that, among all machines that still have some capacity, completes job 2 quickest. Keep going until a machine has been assigned to all jobs. Does this heuristic procedure yield the optimal solution for this problem? If it does, see whether you can change the job times so that the heuristic does not yield the optimal solution.
Solve the question below using the attached excel templates with formulas for renting both slow and fast copies (labeled in the excel tabs). Question: The Decision Sciences Department is trying to determine whether to rent a slow or a fast copier. The department believes that an employee’s time is worth $15 per hour. The slow copier rents for $4 per hour, and it takes an employee an average of 10 minutes to complete copying. The fast copier rents for $15 per hour, and it takes an employee an average of six minutes to complete copying. On average, four employees per hour need to use the copying machine. (Assume the copying times and interarrival times to the copying machine are exponentially distributed.) Which machine should the department rent to minimize expected total cost per hour?
Easy Moving, a moving company, is seeking outside advice from a consultant (you) about the appropriate selection measures to use to analyze job candidates. The position that the company most often hires for is a Driver/Mover. Individuals in this job must be able to drive long hours, and lift and carry heavy objects for long periods of time. When people are moving from one home to another they contact Easy Moving to take care of relocating all of their belongings. The people responsible for the move are the Drivers/Movers. Because driving a truck is an essential function of the job, individuals must not only be physically capable of driving, but also must have an impeccable driving record. Driving a truck can be considered a safety hazard if the individuals were not in the right frame of mind to be a good driver. Easy Moving should keep these things in mind when analyzing applicants. Additionally, individuals applying for a Driver/Mover position with Easy Moving must have the physical…

Consider again the case of One Hour Loan. Recall that activity 1 takes 4 minutes/loan,activity 2 takes 5 minutes/loan, activity 3 takes 7 minutes/loan, activity 4 takes 2 minutes/loan, and activity 5 takes 4 minutes/loan. Recall further that currently the assignment of tasks to workers is as follows: W1 does activity 1, W2 does activities 2 and 3,and W3 does activities 4 and 5.How would you rebalance the process to maximize process capacity, assuming that thefive activities have to be carried out in the given order?
During an eight-hour shift, 750 non-defective parts are desired as a result of a manufacturing operation. The default operation time is 15 minutes. As the operators of machine are inexperienced, the actual time they take to perform the operation is 20 minutes, and, on average, a fifth of the parts that start to be manufactured are lost. Assuming that each one of the machines used in this operation will not be available for one hour in each shift, determine the number of machines needed.
