Problem #3 - Jasper Inc. has an air conditioning manufacturing facility in Lakeland - FL for air conditioning SKUS: J101 and J104. The assembly process for each SKU is similar and both require a certain number of hours in the Assembly Department and in the Finishing Department. As a business consultant, Jasper Inc. asked you to apply Linear Programming (LP) to determine the combination for the number of SKUs J101 and J104 to assemble in every month to maximize its revenue when its facility and business operate under the following conditions: ● Each SKU J101 takes 4 hours in the Assembly Department and 2 hours in the Finishing Department. ● Each SKU J104 takes 3 hours in the Assembly Department and 1 hour in the Finishing Department. ● The Assembly Department has 235 hours available in the current production period, while the Finishing Department has 95 hours available. ● Each SKU J101 is sold for $400. Each SKU J104 is sold for $300. Answer the following questions: a. -Identify and…

Mike Reynolds has four assignments due in class tomorrow, and his class times are as follows: Class Psychology 304 Finance 385 Marketing 216 OM 200 Time 9 a.m. 11 a.m. 1 p.m. 2:30 p.m. Each class lasts one hour, and Mike has no other classes. It is now midnight, and Mike estimates that the marketing, finance, psychology, and OM assignments will take him two, three, six, and one hours, respectively. Assume that all time till the last class begins can be spent on completing assignments but each assignment should be done till the time of the class on the same subject. (Mike can prepare assignments for the next classes during previous classes.) ✓ Use the Excel Sequencing template to determine how he should schedule the work. Use minus sign to enter negative lateness values, if any. Enter the half an hour value as 0.5, e.g., 3:30 p.m. should be entered as 15.5. If your answer is zero, enter "0". Round your answers for the due date, lateness, and tardiness to one decimal place. Round your…

James Mason is an excellent sportsman and in his earlier years he represented his country in basketball. James still plays competition basketball and also trains a District Representative Team preparing for the National Championships. James is required to keep accurate medical records for each member of the squad, especially recording any physical weakness or injury that they may display. James requires the District Team to train three nights per week on the outside courts that are provided by the Local Smithfield Council. The team trains under lights from 6:00pm to 7:00pm on Monday, Wednesday and Friday nights. James is always there to supervise the team and improve the team’s skills. On Friday 17th March it had been raining and two of the lights for the courts were not working and this resulted in very poor visibility for all players. However, James decided to go ahead with the training session even though it had been raining and the courts were very slippery and the lighting was…
Supertronics, Inc., would like to know how the firm’s profit-ability is altered by product mix. Currently, product mix isdetermined by giving priority to the product with the highestper-unit contribution margin (defined as the difference be-tween price and material cost). Details on the Supertronicsproduct line, including processing time at each workstation,follow:a. Assume that Supertronics has 5,500 minutes of capacityavailable at each workstation each week. Develop a linearprogram to define the production mix that maximizescontribution margin.b. Solve your formulation using a computer package such asPOM for Windows. c. Given your solution for part (b), which machine is thebottleneck?d. How would your formulation and solution in part(b) change if 50 units of each product were alreadycommitted to customers and thereby had to beproduced?
A garment manufacturing has already finishedgarments to iron/press in order to prepare for selling them in the market. There aretwo kinds of garments, namely: poloshirt and t-shirts. Poloshirt is to be sold atP200 per piece while t-shirt at P50 each. Ironing/pressing one piece of polotshirttakes 30 minutes while t-shirt takes 12 minutes. The owner of the garment factoryhas a total of 7 finishing workers, who each works 8 hours per day. Four (4) ofwhich are assigned as pressers and three (3) as packagers. For one day, theowner would like to maximize his profit.Using linear programming, determine how many pieces of poloshirts and howmany pieces of t-shirts should be sold in the market in day in order to maximizethe profit. In line with your answer on the number of pieces of poloshirts andnumber of pieces of t-shirts to be sold in the market, compute for the profit.Select the best answer from the choices enumerated below.You may use linear equations and/or inequalities to arrive at the…
Gerald Glynn manages the Michaels Distribution Center. After careful examination of his database information, he has determined the daily requirements for part-time loading dock personnel.

Give preference to the S-Su pair in case of a tie. (Note: If there is a tie that cannot be broken by following the preference to the S-Su pair, choose the pair closest to the beginning of the considered week.) The minimum number of workers is 7 workers. (Enter your…
Assuming the following: Warehouse 1 has outbound goods volume - 2,500 units Warehouse 2 has outbound goods volume - 1,300 units Warehouse 3 has outbound goods volume - 5,000 units Given the assumptions and grid coordinates above, the following: d1x= 200, d2x= 300, d3x= 100, d1y= 50, d2y= 100, d3y= 150 And V1= 2,500, V2= 1,300, V3= 5,000 Which is equal to: Cx= (200 x 2,500) + (300 x 1,300) + (100 x 5,000) / (2,500 + 1,300 + 5,000) = 158 Cy= (50 x 2,500) + (100 x 1,300) + (150 x 5,000) / (2,500 + 1,300 + 5,000) = 114 Use the numerical example set up above to demonstrate how the centre of gravity location technique is used.
