can you solve numbers 4 and 5 please. I have provided the answer for the first 3 questions. thanks.

all clear?

Question 2 (21points) Those of you who have eaten at Bliss House know that they have a very efficient production process. But is it as efficient as possible? Sandwich preparation at Bliss is as follows: customers place and pay for their order, they give the receipt to the bald dude who shouts their order, the meat is then grilled while, simultaneously, the onions/mushrooms/peppers are sauted with seasonings, the meat and sauted items are then assembled in a sandwich, which is toasted, and wrapped. This process is depicted below: each box represents a step in the process and specifies the time required by the person/machine used for that step. Note there are five grilling machines, three griddles for sauteing, and four toasters. Grill Meat 10 minutes Grill 1 Grill 2 Grill 3 Toast Grill 4 1 minute Toaster 1 Grill 5 Cash Register: Place order and pay 1 minute Order Dude: Give receipt to dude to start order 30 seconds Assemble Toaster 2 Wrap 15secs 15secs Toaster 3 Sautee: Sautee onions and add seaoning 3 minutes Toaster 4 Griddle 1 Griddle 2 Griddle 3 1. (3 points) What is the process cycle time of this process? 2. (4 points) Where is the bottleneck? Explain. Would the bottleneck be affected if one griddle is out of order? 3. (3 points) What is the process time of the system? 4. (5 points) it is forecasted that in one day (1day = 20 hours), Bliss House experiences demand for 750 sandwiches. Does current production process have the capacity accommodate demand? Explain. 5. (6 points) Assume that the marginal profit from one sandwich is $2. Bliss house has capital of up to $250000 that can be invested to improve the business and increase capacity. The cost of a new toaster is $50000; the cost of a new grill is $125000; and that of a new griddle is $75000. We assume that Bliss House will undertake an investment if that investment generates, in the next two years, additional profits that cover the initial capital; (1 year = 350 days). Having in mind your previous analysis (1-4), what do you recommend Bliss House does? 1. process cycle time of this process 20x60 750 -1.6 min Process capacity order process 60 0.5 120 per hour Gorill process 5x 60 30 per hour 10 60 60 per hour cash register - Sauteing 3x60 3 3. 4XGO Go per hour Toast - *240 per hour Assemble 60 = 240 per hour 0.25 Wrapping 60 0.25 =) 240 per hour. 2. Bottleneck is the grilling process with output of 30 per hour. If one griddle is out of order, this output will be down by 2/3 factor that is 60 - 40 per hour. 23 If one griddle foils, the bottleneck will remain same 3. process time 16 min ie sum of all the steps. The process is able to produce 30x20 Wat is equal to 600 items, since the max capacity is 30 per hour. which is less than thie needed capacity Hence, this process is incapable of meeting the demand. * If the process is improved to meet the demand, increase in the capacity, new bottleneck capacity 6x60 10 = 36 per hour. * Increase in daily capacity = (36-30) x20 =120 profit = 120x2 = 240 per day. profit in next two years = 350x240 - 84000 the modification should not be undertaken, since the profit is not sufficient to meet the expenses
