Beck Manufacturing Capacity Analysis and Bottleneck Solutions
This paper analyzes the current production capacity of Beck Manufacturing across four machining operations: milling, grinding, boring, and drilling. Using per-hour output rates and reject percentages, it calculates daily production totals across two eight-hour shifts and projects output under a proposed third shift. The paper identifies potential bottlenecks created by the significantly higher output rate of the boring center relative to the other operations and proposes a revised routing strategy to balance workloads across all four production centers, maximizing throughput and minimizing idle time.

What makes this paper effective
- Uses concrete numerical data to ground every claim, moving logically from current output rates to daily totals to projected third-shift figures.
- Identifies a specific, quantified bottleneck (the boring center running ~33% faster than grinding and drilling) rather than making vague efficiency claims.
- Proposes a practical re-routing solution that accounts for the relative parity between the grinding and drilling centers, showing awareness of real-world scheduling constraints.
Key academic technique demonstrated
This paper demonstrates applied quantitative reasoning in an operations management context. The author translates machine run times and reject rates into actionable throughput figures, then uses percentage comparisons to pinpoint where production imbalances occur. This is a core technique in manufacturing analysis — using data to diagnose system constraints before prescribing solutions.
Structure breakdown
The paper opens by presenting baseline machine data in tabular form, then calculates two-shift daily output. It introduces the third-shift scenario and immediately stress-tests it by comparing center-by-center output rates. The bottleneck is identified with specific percentage gaps, and the paper closes with a proposed routing workaround. The structure follows a problem-diagnosis-solution arc typical of operations management case analyses.
Current Production Rates and Daily Output
According to the manufacturer's data, Beck Manufacturing is currently producing product at the following rates across its four machining operations:
| Machine | Run Time | Reject Rate | Output |
|---|---|---|---|
| Milling | 5–2 min | 3% | 145 products per hour |
| Grinding | 7–3 min | 5% | 137 products per hour |
| Boring | 3–1 min | 2% | 176 products per hour |
| Drilling | 6–2.5 min | 7% | 136 products per hour |
Operating two eight-hour shifts per day, Beck Manufacturing currently produces the following daily totals:
- Milled: 2,320 products
- Ground: 2,192 products
- Bored: 2,816 products
- Drilled: 2,176 products
Impact of Adding a Third Shift
One immediate option for increasing output is to add a third eight-hour shift to the two already running each day. Under that scenario, daily production totals would rise to:
- Milled: 3,480 products
- Ground: 3,288 products
- Bored: 4,224 products
- Drilled: 3,264 products
On the surface, adding a third shift appears to be a straightforward solution for scaling output. However, a closer comparison of the per-center figures reveals significant imbalances that must be addressed before this approach can be considered viable. Understanding production bottlenecks is essential when evaluating any capacity expansion plan.
