Chapter 7, Problem 1CS
Rochester Manufacturing’s Process Decision
Rochester Manufacturing Corporation (RMC) is considering moving some of its production from traditional numerically controlled machines to a flexible manufacturing system (FMS). Its computer numerical control machines have been operating in a high-variety, low-volume manner. Machine utilization, as near as it can determine, is hovering around 10%. The machine tool salespeople and a consulting firm want to put the machines together in an FMS. They believe that a $3 million expenditure on machinery and the transfer machines will handle about 30% of RMC’s work. There will, of course, be transition and startup costs in addition to this.
The firm has not yet entered all its parts into a comprehensive group technology system, but believes that the 30% is a good estimate of products suitable for the FMS. This 30% should fit very nicely into a “family”. A reduction, because of higher utilization, should take place in the number of pieces of machinery. The firm should be able to go from 15 to about 4 machines, and personnel should go from 15 to perhaps as low as 3. Similarly, floor space reduction will go from 20,000 square feet to about 6,000. Throughput of orders should also improve with processing of this family of parts in 1 to 2 days rather than 7 to 10. Inventory reduction is estimated to yield a one-time $750,000 savings, and annual labor savings should be in the neighborhood of $300,000.
Although the projections all look very positive, an analysis of the project’s return on investment showed it to be between 10% and 15% per year. The company has traditionally had an expectation that projects should yield well over 15% and have payback periods of substantially less than 5 years.

- Two manufacturing processes are being considered for making a new product. Process A is less capital intensive, with fixed costs of $60,000 per year and variable costs of $700 per unit. Process B has fixed costs of $400,000 annually, with variable costs of $300 per unit. What is the break-even quantity for the two processes? If annual sales are expected to be 700 units, which process should be selected? Operations and Engineering have found a way to reduce the cost of Process B, such that the fixed costs for this process decrease from $400,000 to $300,000 annually. All other costs remain the same. Does this change the process selection for the annual sales volume of 700 units?arrow_forwardTwo different manufacturing processes are being considered for maing a new product.

It has manufactured children’s toys before but nothing as advanced as its latest robot so historical data is at a minimum. The company believes that they can secure the materials for manufacture for between $65-85 per unit and labor costs would be between $15-25 per unit. Management’s expectations are that materials will cost $70 per unit and labor $25 per unit and that 800 units will be sold monthly. Should FAY decide to manufacture the robots in-house, maintenance of the factory machine would cost $15,000 per month. However, management has found that another alternative is for the company to outsource the labor for a flat rate of $35 per unit. The company expects to sell between 750-1000 units per month initially at a price of $149. Provide recommendations for FAE technologies that will maximize profit.
