DreamInflate is a balloon manufacturing company. Balloon manufacturing consists of seven work stations, each performing a single step as indicated in the table below. There are five workers manned for the seven work stations as shown.

Each balloon pack is sold for $6 and has a variable cost of $1. The company has fixed costs of $200 per hour. There is more demand than the overall production system can provide. Based on the information provided, answer the following questions: • What is the cost of direct labor for balloons? • How much profit does DreamInflate make every hour? (note that the cost of direct labor is also a variable cost). What would the profit of DreamInflate be if the variable costs were 10…
Esplanade Marine Parts Inc. wants to produce parts in batches of 60 parts. Each part must be processed sequentially from workstation A to B. Processing Workstation Batch Size (Q) Time per Part 40 seconds A B 60 60 15 seconds a. How many seconds are required to produce the batch under the assumptions of batch processing? Round your answer to the nearest whole number. seconds b. How many seconds are required to produce the batch under the assumptions of single-piece flow processing? Round your answer to the nearest whole number. seconds C. Compare the two solutions in terms of time saved. Round your answer to the nearest whole number. Using the assumptions of -Select- processing saves seconds.
A production process at Kenneth Day Manufacturing is shown in the figure below. The drilling operation occurs separately from, and simultaneously with, the sawing and sanding, which are independent sequential operations. A product needs to go through only one of the three assembly operations (the operations are in parallel). Q 2.1 units/hr Sawing 5 units/hr Sanding Drilling 5 units/hr Welding 2.5 units/hr a) Sawing is the bottleneck. b) The bottleneck time is 28.57 minutes per unit (round your response to two decimal places). c) The throughput time of the overall system is minutes (round your response to two decimal places).

I already find a. I need help with b Bill's Barbershop has two barbers available to cut customer's hair. Both barbers provide roughly the same experience and skill, but one is just a little bit slower than the other. The process flow below shows that all customers go through steps B1 and B2 and then can be served at either of the two barbers at step B3. The process ends for all customers at step B4. The numbers in parentheses indicate the minutes it takes that activity to process a customer. b. What single activity is the bottleneck for the entire process? B what?
Natura has to fill 7 orders for its clients. He requires placing the required product in work boxes and subsequently closing them properly so that the product reaches the customer correctly. The process consists of filling the box and later closing it. As the content of each box and the size of these is different, the filling and closing times of each order is different. These times are shown in the table below. Orders Place in box (minutes) Closing Box (minutes) 1 9 6 2 8 5 3 7 7 4 6 3 5 1 2 6 2 6 7 4 7 a) Find the sequence to complete the orders in the shortest time possible. b) Using a Gantt chart, find the total time in which all orders will be completed using the sequence from part a.

Canine Kernels Company (CKC) manufactures two differenttypes of dog chew toys (A and B, sold in 1,000-count boxes)that are manufactured and assembled on three differentworkstations (W, X, and Y) using a small-batch process (seeFigure 5.12). Batch setup times are negligible. The flowchartdenotes the path each product follows through the manu-facturing process, and each product’s price, demand perweek, and processing times per unit are indicated as well.Purchased parts and raw materials consumed during pro-duction are represented by inverted triangles. CKC can makeand sell up to the limit of its demand per week; no penaltiesare incurred for not being able to meet all the demand. Eachworkstation is staffed by a worker who is dedicated to workon that workstation alone, and is paid $6 per hour. Totallabor costs per week are fixed. Variable overhead costs are$3,500/week. The plant operates one 8-hour shift per day, or40 hours/week. Which of the three workstations, W, X, or Y,has the highest…
