1- Use the process information provided in the following table, when the sequence of flow is A B (any machine can be used if available) C D (any machine can be used if available).

Operation	Number of Units of Equipment	Design Capacity (by equipment)	Planned Utilization (overall)
A	1	255 units/hr	82.5%
B	4	50, 60, 45, 40	86.0%
C	1	265 units/hr	60.0%
D	2	155, 120	87.5%

Calculate the maximum (design) capacity and effective capacity. (Round "Effective capacity" to 2 decimal places.)

2-

Maximum capacity (labor hours):	420 hours per week
Effective capacity ratio:	87%
Actual time worked:	301 hours per week over the last two weeks
On-time delivery %:	83 percent of the jobs are being completed on time

a. Calculate the effective capacity and actual utilization. (Round your answers to 2 decimal places. Enter "Actual utilization" as a percentage rounded to 2 decimal places.)

b. Do we need to add more capacity

• Yes - No

3- Electronics Assembly Inc. is a contract manufacturer that assembles consumer electronics for a number of companies. Currently, the operations manager is assessing the capacity requirements as input into a bid for a job to assemble cell phones for a major global company. The company would assemble three models of cell phones on the same assembly line. Setup time between the phones is negligible. Electronics Assembly Inc. operates two 8-hour shifts for 275 days per year.

Cell Phone	Demand Forecast (phones/year)				Processing Time (minutes/phone)
Mars		36,500				35.6
Saturn		35,500				22.5
Neptune		27,000				18.1

a. Calculate total capacity required.

b. Determine the total operating time available for each assembly line.

c. Calculate the total number of assembly lines required. (Round up your answer to the next whole number.)

4- You have been approached by one of the staff who works testing equipment that passes through your facility. Every day, you receive computers from the university that have been repaired but now need to be tested to ensure that they can work under high stress. This means running them in your test labs. Because the test labs are as stressful on the test equipment as it is on the computers, you have planned for downtime in the past. To get this downtime, you have tried to ensure that effective capacity utilization is about 71 percent. Yet, the staff person has informed you that a backlog of yet-to-be tested equipment is building up. Furthermore, the test equipment is now starting to break at a rate faster than anticipated. To address this issue, you know that the design or maximum capacity is 780 hours and that over the last three weeks, you have spent 630 hours per week testing equipment.

Based on this data, what is our design capacity utilization? (Round your answer to 1 decimal place.)
