On-stream Factor

What is On-stream Factor?
The percentage of time that an NGL plant's production units are operational and producing products, as opposed to being down for maintenance or other reasons.




On-stream Factor measures the efficiency of production processes, directly impacting operational efficiency and financial health.

A high On-stream Factor indicates that assets are being utilized effectively, leading to increased output and reduced costs.

Conversely, a low factor may signal equipment downtime or inefficiencies, which can erode profitability.

Organizations that prioritize this KPI often see improvements in their ROI metric and overall business outcomes.

By leveraging data-driven decision-making, companies can align their strategies to enhance performance indicators like the On-stream Factor.

On-stream Factor Interpretation

A high On-stream Factor reflects optimal asset utilization, while a low value suggests inefficiencies or equipment issues. Ideal targets typically hover around 85% or higher, indicating that production systems are functioning at peak capacity.

  • 85% and above – Excellent performance; minimal downtime
  • 70% to 84% – Acceptable; room for improvement
  • Below 70% – Critical; requires immediate investigation

Common Pitfalls

Many organizations overlook the On-stream Factor, focusing instead on lagging metrics that fail to capture real-time performance.

  • Ignoring scheduled maintenance can lead to unexpected downtimes. Equipment that isn't regularly serviced often breaks down, disrupting production schedules and inflating costs.
  • Failing to train staff on operational best practices results in inefficient workflows. Employees may not utilize equipment optimally, leading to unnecessary delays and resource waste.
  • Overcomplicating production processes can create bottlenecks. Streamlined operations are essential for maintaining high On-stream Factor values, yet many firms add unnecessary steps that hinder efficiency.
  • Neglecting to analyze downtime causes can perpetuate issues. Without a structured approach to variance analysis, organizations may miss opportunities to enhance performance and reduce costs.

Improvement Levers

Enhancing the On-stream Factor requires a proactive approach to operational efficiency and continuous improvement.

  • Implement predictive maintenance strategies to minimize unplanned downtimes. By using data analytics, organizations can anticipate equipment failures and schedule maintenance before issues arise.
  • Invest in employee training programs focused on operational excellence. Well-trained staff are more likely to operate machinery efficiently, reducing errors and improving output.
  • Streamline production workflows to eliminate bottlenecks. Regularly review processes and remove unnecessary steps to enhance throughput and reduce cycle times.
  • Utilize real-time monitoring systems to track performance. Dashboards that provide analytical insights into production metrics enable quick adjustments to maintain optimal operations.

On-stream Factor Case Study Example

A leading manufacturer in the automotive sector faced challenges with its On-stream Factor, which had dropped to 68%. This decline resulted in significant production delays and increased operational costs, threatening the company's market position. To address this, the executive team initiated a comprehensive review of their production processes, identifying key areas for improvement.

They implemented a robust predictive maintenance program, utilizing IoT sensors to monitor equipment health in real-time. This allowed them to schedule maintenance proactively, reducing unexpected downtimes by 30%. Additionally, they revamped employee training programs, focusing on best practices for equipment operation and maintenance.

Within a year, the On-stream Factor improved to 82%, translating into a 15% increase in production output. The company also reported a significant reduction in operational costs, enabling them to reinvest savings into innovation and product development. This strategic alignment not only enhanced their competitive position but also improved overall financial health.

FAQs

What is a good On-stream Factor?

A good On-stream Factor typically ranges from 85% to 95%. Values in this range indicate that production processes are running efficiently with minimal downtime.

How can I calculate the On-stream Factor?

The On-stream Factor is calculated by dividing the actual production time by the total available production time. This metric provides insight into how effectively production resources are utilized.

What impacts the On-stream Factor?

Factors such as equipment reliability, workforce efficiency, and production scheduling significantly impact the On-stream Factor. Addressing these areas can lead to substantial improvements.

Is the On-stream Factor the same as overall equipment effectiveness (OEE)?

While related, the On-stream Factor focuses specifically on production time, whereas OEE considers availability, performance, and quality. Both metrics are essential for a comprehensive view of operational efficiency.

How often should the On-stream Factor be reviewed?

Regular reviews, ideally on a monthly basis, are recommended to identify trends and address issues promptly. Frequent monitoring allows for timely interventions to maintain high performance.

Can the On-stream Factor be improved quickly?

While some improvements can be made quickly, sustainable changes often require a long-term strategy. Focusing on training, maintenance, and process optimization yields the best results over time.
