PA 8-4 (Algo) In the welding operations of a bicycle manufacturer…

In the welding operations of a bicycle manufacturer, a bike frame has a flow time of about 13.55 hours. The time in the welding operation is spent as follows: 1 hour waiting in front of the cutting machine for the batch to start, 2 hours waiting for the setup of the machine, 1 hour waiting for the other pieces of the batch to go through cutting, 2 minutes at the cutting machine, and 4 hours waiting for the transfer to the welding machine. Then, at the welding machine, the unit spends 2 hours waiting in front of the welding machine for the batch to start, 2 hours waiting for the setup of the welding machine, 0.55 hours waiting for the other pieces of the batch to go through welding, 0.3 minutes at the welding machine, and 1 hour waiting for the transfer to the next department.

Determine the exact flow time. What is the value-added percentage of the flow time? Note: Round your percentage answer to 4 decimal places.

PA 8-7 (Algo) The welding department supplies parts to…

The welding department supplies parts to the final assembly line. Management decides to implement a kanban system and has collected the following data.

The daily demand is 2,500 units.
The production lead time is 4 days (this includes processing time, transport time, and waiting time).
Management has decided to have 2 day(s) of safety stock
One container fits 400 units

How many kanban containers will be needed to support this system? Note: Round up to next whole number.

Additional Algo 8-13 Information Turnaround Time

A manufacturing process with five steps has a cycle time of 2.9 minutes per unit.

What is the maximum inventory that can be maintained in the process without exceeding an information turnaround time of 100 minutes? Note: Round your answer down to the next lowest integer value.

Additional Algo 8-4 Wasting Time of a Flow Unit

In a manufacturing process, a molded part spends 8 hours in inventory before being placed in a deburring machine, where the part is processed for 3 minutes. After deburring, the part spends 5 hours in inventory waiting for its turn on the polishing machine. The part then spends 6 minutes in polishing before waiting 8 hours in line to be painted. The part goes through a painting process that takes 9 minutes, then spends 10 hours in inventory before being shipped to the customer.

What is the percentage of value-added time for the part? Note: Round your answer as a percentage to 4 decimal places.

Additional Algo 8-6 Utilization in a Pull System

Oranges are processed through a two-step process. First, the fruit is cleaned in a machine with a capacity of 1,850 oranges per hour. Next, the fruit is labelled with a machine that has a capacity of 900 oranges per hour. Demand for oranges exceeds supply.

In a pull system, what will be the utilization of the first machine? Note: Round your answer to 3 decimal places.

Additional Algo 8-3 Wasting Time of a Flow Unit

In a salon, an average customer will wait 27 minutes before spending 26 minutes with the stylist.

What is the percentage of value-added time? Note: Round your answer as a percentage to 1 decimal place.

Additional Algo 8-9 Target Staffing

The labor content of a book is determined to be 35 minutes. If 66 books need to be produced in each 8-hour shift.

What is the target manpower? Note: Round your answer to 1 decimal place.

Additional Algo 8-5 Percent Value-Added Time

Patients seeking care at the County General emergency room wait, on average, 7 minutes before seeing the triage nurse who spends, on average, 4 minutes assessing the severity of their problem. The most serious cases are seen first and the less serious often have to wait. On average, the wait time before being taken to the examination room is 83 minutes. In the examination room, a nurse spends about 8 minutes taking vitals and making notes on the patient’s condition. The patient then waits for the doctor. This wait averages 27 minutes. Treatment times by the doctor average 16 minutes. Following treatment, patients wait 18 minutes for the nurse to come to discuss the post treatment instructions. It takes about 3 minutes to review with the patient these instructions before they leave. Considering any time spent interacting with a nurse or doctor as value-added time.

What is the present value-added time in a trip to the emergency room? Note: Round your answer as a percentage to 2 decimal places.

PA 8-4 (Algo) In the welding operations of a bicycle manufacturer…

Determine the exact flow time. What is the value-added percentage of the flow time? Note: Round your percentage answer to 4 decimal places.

Answer and Explanation

The exact flow time is 815.30 minutes. Of this, only 2.3 minutes are value-added time. Thus, the percentage of value-added time is:

Value-added time of the flow unit / Flow time = 2.3 minutes / 815.30 minutes = 0.002821 = 0.2821%

How many kanban containers will be needed to support this system? Note: Round up to next whole number.

Answer and Explanation

We first determine the amount of demand during the production lead time.

Demand during lead time = Lead time × Daily demand = 4 days × 2,500 units / day = 10,000 units Please click on the Icon below to purchase the full answers at only $5
