What cycle time would match capacity and demand if demand is 120 units a day, there are two shifts of 480 minutes each, and workers are given three half-hour breaks during each shift, one of which is for lunch or dinner?

Material delays have routinely limited production of household sinks to 400 units per day. If the plant efficiency is 80%, what is the effective capacity?

The statement Michael will sell his car and buy a bicycle or rent a truck. could be interpreted to mean either a: Michael will sell his car, and he will buy a bicycle or rent a truck. or b: Michael will sell his car and buy a bicycle, or he will rent a truck. Describe a situation in which b is true and a is false

In simple linear regression, the dependent variable is the: A. Input variable B. $x$ variable C. $y$ variable D. Coefficient of determination

The Friendly Sausage Factory (FSF) can produce hot dogs at a rate of 5,000 per day. FSF supplies hot dogs to local restaurants at a steady rate of 250 per day. The cost to prepare the equipment for producing hot dogs is $66. Annual holding costs are 45 cents per hot dog. The factory operates 300 days a year. Find a. The optimal run size. b. The number of runs per year. c. How many days does it take to produce the optimal run quantity?

Find the number of batches of sugar that should be manufactured annually in the earlier exercise.

A tourist center is open on weekends (Friday, Saturday, and Sunday). The owner-manager hopes to improve scheduling of part-time employees by determining seasonal relatives for each of these days. Data on recent traffic at the center have been tabulated and are shown in the following table:

a. Develop seasonal relatives for the shop using the centered moving average method.

b. Develop seasonal relatives for the shop using the SA method.

c. Explain why the results of the two methods correlate the way they do.

Elite Style inspects 500 hair dryers manufactured and finds 495 to have no defects. There are 20,000 hair dryers in their warehouse. a. What is the experimental probability that a hair dryer will have no defects? b. Predict the number of hair dryers that will have no defects in the warehouse.

b. Predict the number of hair dryers that will have no defects in the warehouse.

Determine the number of cycles per day and a production quantity per cycle for this set of products that achieves fairly level production:

Assume the production sequence will be F-G-H-K.

Consider the following tasks that must be assigned to four workers on a conveyor-paced assembly line (i.e., a machine-paced line flow). Each worker must perform at least one task. There is unlimited demand.

$$\begin{array}{lc} & \text{Time to Complete Task (seconds)} \\ \hline \text{Task 1} & 30 \\ \text{Task 2} & 25 \\ \text{Task 3} & 15 \\ \text{Task 4} & 20 \\ \text{Task 5} & 15 \\ \text{Task 6} & 20 \\ \text{Task 7} & 50 \\ \text{Task 8} & 15 \\ \text{Task 9} & 20 \\ \text{Task 10} & 25 \\ \text{Task 11} & 15 \\ \text{Task 12} & 20 \\ \end{array}$$

The current conveyor-paced assembly-line configuration assigns the workers in the following way:

• Worker 1: Tasks 1, 2, 3
• Worker 2: Tasks 4, 5, 6
• Worker 3: Tasks 7, 8, 9
• Worker 4: Tasks 10, 11, 12

a. What is the capacity of the current line? b. What is the direct labor content? c. What is the average labor utilization (do not consider any transient effects such as the the line being emptied before breaks or shift changes)? d. How long would it take to produce 100 units, starting with an empty system? The firm is hiring a fifth worker. Assume that tasks are allocated to the five workers to maximize the capacity of the line, subject to the conditions that (i) a worker can only perform adjacent operations and (ii) all tasks need to be done in their numerical order. e. What is the capacity of this line now? Again, assume the firm has hired a fifth worker. Assume further that tasks are allocated to maximize the capacity of the line and that tasks can be performed in any order. f. What is the maximum capacity that can be achieved? g. What is the minimum number of workers that could produce at an hourly rate of 72 units? Assume the tasks can be allocated to workers as described in the beginning (i.e., tasks cannot be done in any order).

Update the master schedule shown in before given these updated inputs: It is now the end of week 1; customer orders are 25 for week 2, 16 for week 3, 11 for week 4, 8 for week 5, and 3 for week 6. Use the MPS rule of ordering production when projected on-hand inventory would be negative without production. Prepare the master schedule for weeks 2–8.

Specifications for a part for a DVD player state that the part should weigh between 24 and 25 ounces. The process that produces the parts has a mean of 24.5 ounces and a standard deviation of .2 ounce. The distribution of output is normal.

a. What percentage of parts will not meet the weight specs?

b. Within what values will 95.44 percent of sample means of this process fall, if samples of n = 16 are taken and the process is in control (random)?

What is the kanban aspect of JIT?
