Machine downtime has long been recognized as a formidable obstacle to productivity within the manufacturing industry. The significance of this issue lies in the fact that when machines remain idle, the value created for customers diminishes. Each minute spent in downtime equates to potential profits lost, amounting to thousands in damages. Although planned maintenance and changeover processes necessitate some downtime, many industrial companies grapple with preventable instances of unplanned downtime. If production goals are consistently missed, it is highly likely that the overall equipment effectiveness (OEE) is also suffering. By examining the primary causes of excessive downtime in manufacturing facilities, implementing necessary solutions, and leveraging advanced connected workforce platforms like Nirmalya Enterprise Platform Suite, factories can effectively boost uptime and optimize operational efficiency.
Machine downtime is a critical aspect of manufacturing operations, encompassing any periods when machines are not operating. This downtime can be broadly classified into two categories: planned downtime and unplanned downtime. Planned downtime is scheduled and can arise due to factors such as maintenance, material shortages, or team meetings. On the other hand, unplanned downtime is unpredictable and often results from mechanical issues or operator errors. While some downtime is normal in manufacturing, excessive and persistent unplanned downtime may indicate underlying systemic issues within a facility. Therefore, it is essential for companies to proactively address downtime to enhance operational efficiency and minimize production interruptions.
Unforeseen downtime in machines can occur due to a variety of reasons, leading to the loss of valuable production time and materials for manufacturers. This ultimately impacts profits negatively. Below are some of the typical causes for unplanned machine downtime:
Maintenance Culture
In environments that adopt a break/fix strategy, where issues are addressed only after they have caused a breakdown, downtime occurs more frequently and lasts longer compared to environments that prioritize proactive maintenance to prevent failures.
Equipment Failure
Machinery and equipment may experience failures due to reasons such as normal wear and tear, inadequate maintenance, improper operation, or substandard repairs, resulting in unexpected halts in production.
Supply Chain Disruptions
Supply chain disruptions lead to production halts from material shortages, supply delays, or quality issues, impacting deadlines and customer orders. Businesses should anticipate and address these issues to minimize delays and maintain efficiency.
Power Outages
Power outages can lead to an abrupt halt in production and may cause delays in resuming operations. It is an unexpected event that can have a significant impact on the workflow.
Issues with Software and Systems
Instances of software and system malfunctions can cause glitches, bugs, or failures in machinery, leading to unplanned downtime. These disruptions can delay operations and affect productivity. Prompt identification and resolution of these issues are essential to minimize their impact on manufacturing.
Employee Mistakes
Errors made by employees, including lack of attention, misunderstanding of instructions, or errors in judgment, have the potential to cause production stoppages.
Safety Incidents
Safety incidents, such as accidents, can lead to immediate shutdowns either directly following the incident or during the investigation and response process.
While some causes like power outages and material shortages are typically beyond our control, the majority of unplanned downtime can be prevented or promptly addressed. By engaging your team with the appropriate tools and strategies to optimize Overall Equipment Effectiveness (OEE), you can effectively reduce downtime.
In order to minimize downtime, it is essential to have a thorough understanding of the calculations involved. This involves collecting sufficient data from various sources, such as equipment, personnel, systems, and procedures, to identify areas in need of enhancement. Manufacturers typically measure machine downtime by establishing a planned operating schedule and tracking both planned and unplanned downtime occurrences on a monthly basis. This data is then reviewed to identify trends and compare against previous months. Utilizing advanced EAM solutions like Nirmalya EAM simplifies digital storage of production data, making the task more efficient. To calculate actual operating time, total downtime is subtracted from the planned operating time. For example, if 40 hours of downtime occur within a 240-hour planned period, the actual operating time would be 200 hours. This result can be converted to a downtime percentage, which in this case is approximately 16.7%.
To analyse downtime on an individual asset level, calculate daily revenue by dividing total revenue by planned operating time. Then, identify how much revenue is affected when a particular machine is down. This helps in determining asset criticality and quantifying the financial impact of downtime. By comparing the impact of different assets on daily revenue, you can prioritize maintenance efforts and improve overall operational efficiency.
To prioritize equipment failures and save money, it is important to identify the costliest issues first. This can help stop financial losses in your factory. However, simply knowing about the failures is not enough. You need the proper tools and systems in place to address the root cause of these problems effectively.
