4) JMMJ Shop needs to assign 4 jobs to 4 workers. The cost of performing a job is afunction of the skills of the workers. The table below shows the cost of theassignments. Worker 1 cannot do job 3 and worker 3 cannot do job 4.Requirements:a) Discuss what needs to be done to address the restriction that worker 1cannot do job 3 and worker 3 cannot do job 4.b) Determine the optimal assignment using the Hungarian method.Worker2342$50 $50$70$90$70$40$30$20Job3$20$50$604$20$30$70

One possible solution method for the machine-to-job assignment problem is the following heuristic procedure. Assign the machine to job 1 that completesjob 1 quickest. Then assign the machine to job 2 that, among all machines that still have some capacity, com-pletes job 2 quickest. Keep going until a machine has been assigned to all jobs. Does this heuristic procedureyield the optimal solution for this problem? If it does,see whether you can change the job times so that theheuristic does not yield the optimal solution.
Suppose a furniture builder has two models of a bookcase: standard and artisan. The standard model requires 5 hours to assemble and 1 hours for finishing touches. The artisan model requires 2 hours to assemble and 4 hours for finishing touches. Based on their current staffing, they can manage a maximum number of assembly hours available is 50 per day, and the maximum number of finishing hours available is 64 per day. Let x = the number of standard model bookcases produced per day and y = the number of artisan model bookcases produced per day. Write the system of inequalities that represents the maximum number of bookcases that can be produced in one day. 0 Graph the system of inequalities, remember to include x >0 and y > 0 in your graph to get full credit. You will need to include four lines. 25 24 VI
3. Create the following calculated columns. a) In I4, and J4, use a VLOOKUP function that will look up the Product Price and Product Cost based on the Product Sold column which lists an ID number. [Hint: The Product Table sheet lists the Price and Cost] If any error messages appear, check the Range Lookup. b) In K4, use a formula to calculate Profit. Hint: Profit =(Product Price-Product Cost)*Units Sold 4. Format columns I, J, and K as currency with two decimal places. 5. Make a copy of the Sales sheet and rename it Online Sales by Date. Place this sheet to the right of the Sales sheet. Answer the following question by filtering the data accordingly.a) What was the total Profit for Online Sales? b) Sort the results by Date Sold (A/Z). * so apparently I need to learn to use the VLOOKUP to find a product on the first page and be able to get the Product Price and Cost from the second page. The following formula is NOT working - =VLOOKUP(D4, ProductTable!A:B, 2,FALSE). I need an EXACT…

An optimization study is conducted for a plant layout and operations. The final design for the operations layout may have several options. The process will initially utilize six devices running at the same time, then, five groups of employs will conduct manually the final process. State the possible number of different process routes that will be adopted. Select one:
Q2. Pharmaceutical company producing a single product sold it through five agencies situated in different cities. All of sudden there rouse a demand for the product in another five cities that didn't agency of the company. The company is now facing the problem of deciding on how to assign the existing agencies in order to dispatch the product to needy cities in such a way that the travelling distance is minimized. The distance between the surplus and deficit cities in kilometer is given the following table. Surplus city Deficit cities Deficit cites a b d. e A1 160 130 115 190 200 B1 135 120 130 160 175 C1 140 110 125 170 185 D1 50 50 80 80 110 E1 55 35 80 80 105 Determine the optimum assignment schedule.
At Long John Silver’s (LJS), Platter 1 comes with 2 pieces of fish, 3 pieces of chicken, and 5 fried shrimp, while Platter 2 comes with 3 pieces of fish, 1 piece of chicken, and 8 fried shrimp. Platter 1 sells for 8 dollars and platter 2 sells for 10 dollars. If LJS has access to 1000 pieces of fish, 1200 pieces of chicken, and 2600 fried shrimp, what is the optimal number of platters LJS should make in order to maximize its profit? Note that the constraints relate to (please use these in order) fish, chicken, and shrimp. Note that problem 7 had three constraints (excluding the non-negativity constraints), and setting two pairs of those constraints to equality led to two extreme points on the feasible region. What INFEASIBLE point was at the intersection of the other pair of constraints? In the optimal solution to problem 7, the optimum was found at the intersection of two of the constraints that were not non-negativity constraints. Call these “binding” constraints. One of those…
(4) Assume that a website www.funwithmath1600.ag has three pages: Page A: KingAlgebra Page B: Learn1600andWin • Page C: Linear AlgbraIsEverywhere Each page has some links to the other pages of this website and no pages links to any page outside this website. Page A has three links to page B and only one link to page C. • Page B has three links to page A and two links to page C. • Page C has one link to page A and two links to page B. A student decides to explore this website starting from page A. Since reading content is always a boring task (is it?!) they decide to choose one of the links in page A with equal probability and click on the link to see the next page. As a result, on the next step, they will end up on page B with probability 3/4 and on the page C with probability 1/4. This process is then continued by the student with the same rule: Go the next page by clicking, with equal probability, on one of the existing links that are on the present page.

Richard Dulski's firm is about to bid on a new radar system. Although the product uses new technology, Dulski believes that a learning rate of 75% is appropriate. The first unit is expected to take 700 hours, and the contract is for 40 units. a) The total amount of hours to build the 40 units = 9606 hours (round your response to the nearest whole number). b) The average time to build each of the 40 units = hours (round your response to two decimal places).
