2-The process of making hotdogs involves six activities: “grind”, “mix”, “stuff”, “cook”, “peel”, and “inspect”. If the capacity of activity “cook” determines the process capacity, which of the following statements are true?
a- Activity “cook” is a bottleneck activity.
b- The activity time of all the other five activities is shorter than activity "cook".
c- Cycle time of the process of making hotdogs is equal=1/capacity of activity “cook”.
d- Increasing the capacity of activity “grind” can increase the capacity of the process of making hotdogs.
All statements are correct
Only statement 'b' is correct
Only statements 'a' and 'b' are correct
Only statements 'a', 'b' and 'c' are correct
Only statement 'a' is correct

Consider a production line with five stations. Station 1 can produce a unit in 9 minutes. Station 2 can produce a unit in 10 minutes. Station 3 has two Identical machines, each of which can process a unit in 12 minutes (each unit only needs to be processed on one of the two machines). Station 4 can produce a unit in 5 minutes. Station 5 can produce a unit in 8 minutes.
a. which station is the bottleneck station?Explain with a diagram.
b. What is the capacity of the production line ?
c. Compute the throughput time.

In a job shop, effective capacity is only 88 percent of design capacity, and actual output is 69 percent of effective output. What design capacity would be needed to achieve an actual output of 11 jobs per week? What is its effective capacity?a. The Design Capacity needed to achieve the required actual job outputs =( ) (round to whole number)b. The Effective Capacity needed to achieve the required actual job outputs =( ) (round to whole number)

The following diagram describes a service system where customers go through either of the two parallel three-step processes (A1-A2-A3 or B1-B2-B3) and then merge into a single line for the final step (F4). Each step has one worker assigned to it (total of 7 workers). The numbers in parentheses are the times in minutes for each step of the process.
( see attached image)
What is the capacity of the entire system in terms of customers per hour? Hint: Start with calculating hourly capacity of A1-A2-A3 and B1-B2-B3.
How much will the system capacity change if a second worker is assigned to step F4?

To meet holiday demand, Penny’s Pie Shop requires a pro-duction line that is capable of producing 50 pecan pies perweek, while operating only 40 hours per week. There areonly four steps required to produce a single pecan pie withrespective processing times of 5 minutes, 5 minutes, 45 min-utes, and 15 minutes.a. What should be the line’s cycle time?b. What is the smallest number of workstations Penny couldhope for in designing the line considering this cycletime?c. Suppose that Penny finds a solution that requires onlyfour stations. What would be the efficiency of this line?

A young mechanical engineer devised two different approaches to completing aproduction task. Both methods entail the purchase of the same working space as well asother capital equipment that will only be employed for this operation.A crew of three guys costing P30.00 per hour is required for Method A. This approachwill produce 10 units per hour, two of which will be rejects. Method B requires aworkforce of two workers, each of whom costs P35.00 per hour, to produce eight unitsper hour, one of which will be rejected. Each reject costs P20.00 because direct materialis lost. If a certain total number of units is to be produced, find which method iseconomical.

The roller coaster at Treasure Island Amusement Park consists of 20 cars, each of which can carry up to two passengers. According to a time study, each run takes 4.5 minutes, and the time to unload and load riders is 5.5 minutes. What is the theoretical capacity of the system in number of passengers per hour? Round your answer down to the nearest whole number.
_________ passengers per hour
