**Explanation:**
A production line is said to be balanced when the operation time at each station is the same. Let's understand why this is the correct answer.
**What is a production line?**
A production line is a sequence of workstations or machines where a product is assembled or manufactured. Each workstation performs a specific task, and the product moves from one workstation to another until it is completed.
**Balanced Production Line:**
A balanced production line is one where the work is evenly distributed among all the workstations, ensuring that each workstation has a similar workload. This balance is achieved by matching the operation time at each station.
**Importance of Balanced Production Line:**
Having a balanced production line is important for several reasons:
1. Efficiency: A balanced line ensures that work is distributed evenly, minimizing idle time and maximizing productivity.
2. Cost-effectiveness: By evenly distributing the workload, a balanced line reduces the need for excess machinery or labor, resulting in cost savings.
3. Quality Control: A balanced line helps maintain consistent quality throughout the production process by ensuring that each workstation has a similar amount of time to complete its task.
4. Flexibility: A balanced line allows for easier adjustments and modifications in the production process. If one workstation needs to be changed or modified, it can be done without disrupting the entire line.
**Why Operation Time Matters:**
The operation time refers to the time required to complete a specific task or operation at each workstation. When the operation time is the same at each station, it ensures that the workload is evenly distributed.
If the operation time varies significantly between workstations, it can lead to imbalances in the production line. For example:
- If one workstation takes longer than others, it can cause bottlenecks and slow down the entire production process.
- If one workstation completes its task too quickly, it can lead to idle time at subsequent workstations, resulting in inefficiency.
By matching the operation time at each station, a balanced production line can be achieved, ensuring that the workload is evenly distributed and maximizing efficiency.
**Conclusion:**
In conclusion, a production line is said to be balanced when the operation time at each station is the same. This ensures that the workload is evenly distributed, leading to increased efficiency, cost-effectiveness, and quality control.
