Tombro Industries is in the process of automating one of its plants and developing a flexible manufacturing system. The company is finding it necessary to make many changes in operating procedures. Progress has been slow, particularly in trying to develop new performance measures for the factory.
In an effort to evaluate performance and determine where improvements can be made, management has gathered the following data relating to activities over the last four months:
| Month | ||||||||
|---|---|---|---|---|---|---|---|---|
| 1 | 2 | 3 | 4 | |||||
| Quality control measures: | ||||||||
| Number of defects | 185 | 163 | 124 | 91 | ||||
| Number of warranty claims | 46 | 39 | 30 | 27 | ||||
| Number of customer complaints | 102 | 96 | 79 | 58 | ||||

| Use as a percentage of availability | 95% | 92% | 89% | 85% | ||||
| Setup time (hours) | 8 | 10 | 11 | 12 | ||||

| Delivery cycle time | ? | ? | ? | ? | ||||
| Percentage of on-time deliveries | 96% | 95% | 92% | 89% |
The president has read in industry journals that throughput time, MCE, and delivery cycle time are important measures of performance, but no one is sure how they are computed. You have been asked to assist the company, and you have gathered the following data relating to these measures:
| Average per Month (in days) | ||||
|---|---|---|---|---|
| 1 | 2 | 3 | 4 | |
| Wait time per order before start of production | 9.0 | 11.5 | 12.0 | 14.0 |
| Inspection time per unit | 0.8 | 0.7 | 0.7 | 0.7 |
| Process time per unit | 2.1 | 2.0 | 1.9 | 1.8 |
| Queue time per unit | 2.8 | 4.4 | 6.0 | 7.0 |
| Move time per unit | 0.3 | 0.4 | 0.4 | 0.5 |
Required:
1-a. Compute the throughput time for each month.
1-b. Compute the manufacturing cycle efficiency (MCE) for each month.
1-c. Compute the delivery cycle time for each month.
3-a. Refer to the inspection time, process time, and so forth, given for month 4. Assume that in month 5 the inspection time, process time, and so forth, are the same as for month 4, except that the company is able to completely eliminate the queue time during production using Lean Production. Compute the new throughput time and MCE.
3-b. Refer to the inspection time, process time, and so forth, given for month 4. Assume that in month 6 the inspection time, process time, and so forth, are the same as in month 4, except that the company is able to eliminate both the queue time during production and the inspection time using Lean Production. Compute the new throughput time and MCE.

Over the past three years, since the popular Reverend Timothy Becker has taken over leadership of the congregation, the church has more than doubled in size. It now has approximately 400 registered households. Reverend John Howard has also recently been added as a second minister. Since the Church was rather small in the past, most of its records have been kept on paper forms. However, the Church’s Business Manager, Margie Roberts, has suggested to Reverend Becker that a computerized system might help the Church better meet its information needs and manage its activities. In addition to Ms. Roberts, the Church employs a part-time administrative assistant, Mabel McGregory. Mabel performs clerical duties such as filing, record keeping, answering phone calls, and typing the weekly church bulletin using WordPerfect for Windows on the Church’s only personal computer. A retiree, Leroy Stricty, is…arrow_forward

This results from a surge in the number of customers who have contacted her to highlight problems they have encountered while shopping at the Pet Kingdom store. The complains seem to focus on two areas; billing errors being made at the checkout and variations in the weight of Pet Kingdom branded dried dog food bags. To better understand the situation, Ms Lionheart has requested detailed data to be collected. Table 3 shows the data from the audit of 50 random bills per day issued over the past 30 days. Table 4 presents the weight sampling data (mean and range in kg) for 27 random samples of five observations each taken from the daily dog food deliveries. Ms Lionheart noticed that the number of billing errors increased in the last third of the month. She knows that the company wants high quality standards and wonders if both processes meet 3 sigma standards. She…arrow_forward
