Trek Mini is a toy bicycle manufacturing company producing a five inch small version of the famous Trek bicycles. The assembly process at Trek Mini consists of seven consecutive steps. The steps are summarized below:

• Step 1 (40 sec.): The plastic tube for the frame is cut to size.
• Step 2 (20 sec.): The tube is put together.
• Step 3 (35 sec.): The frame is glued together.
• Step 4 (20 sec.): The frame is cleaned.
• Step 5 (30 sec.): Paint is sprayed onto the frame.
• Step 6 (20 sec.): Wheels are assembled.
• Step 7 (35 sec.): All other parts are assembled to the frame.

Under the current process layout, workers are allocated to the stations as shown here:

Workstation 1: Steps 1, 2
Workstation 2: Steps 3, 4
Workstation 3: Step 5, 6
Workstation 4: Step 7

a) What is the bottleneck in this process? Find the bottleneck time and the throughput time and explain what they mean.
b) Simulate the process for three toy bicycles. Do you confirm the values found in part (a)?
c) What is the capacity of this assembly line, in finished units/hour?
d) Based on recommendations of a consultant, Atlas Inc. decides to reallocate the tasks among the workstations to achieve maximum process capacity. Assume that if a workstation is in charge of two tasks, then the tasks have to go adjacent to each other. Also, assume that the sequence of steps cannot be changed. What is the % increase in capacity that can be achieved by this reallocation?
e) Is it possible for Atlas Inc. to further increase the capacity found in (d) by adding one parallel workstation to the bottleneck workstation? Why or why not?

Yael decides that she no longer enjoys her job, and she quits to open a gluten-free, dairy-free kosher bakery. she pays a monthly rent for her store of $2,000. her labor costs for one month are $4,500, and she spends $6,000 a month on nut flours, sugar, and other supplies. yael was earning $2,500 a month working as a bank teller. these are her only costs. her monthly revenue is $14,000. which of the following statements about yael’s costs and profit are correct? correct answer(s) an accountant would say she is earning a monthly profit of $1,500. her implicit costs are $2,500 a month. an economist would tell her that she is experiencing a loss. her total costs are $12,500 a month. her explicit costs include the labor, rent, and supplies for her store. her economic profit is $1,500 a month.

Suppose an economy has only two sectors: goods and services. each year, goods sells 80% of its outputs to services and keeps the rest, while services sells 62% of its output to goods and retains the rest. find equilibrium prices for the annual outputs of the goods and services sectors that make each sector's income match its expenditures.
