نگهداری و تعمیرات برنامه ریزی شده

Planned maintenance and repair refers to a set of activities that are carried out regularly and preventively to maintain and optimize the performance of various equipment, buildings and systems. In this method, repairs and maintenance are carried out based on a specific schedule and independent of the occurrence of failures.

Planned maintenance begins with a problem and identifies the materials, tools, and tasks necessary to work on the problem. The planning process includes inspection, part ordering, process description and work prioritization. These responsibilities rest with the maintenance scheduler. A planned Maintenance and repair schedule for a facility may include scheduling, but sometimes scheduling is done separately through a maintenance schedule.

The main purpose of planned maintenance and repairs is to determine what work should be completed and how it should be done, or in general, it can be said that its purpose is to prevent breakdowns and reduce the risks of sudden equipment stoppage. By performing regular and preventive repairs and maintenance, the useful life of the equipment increases and the possibility of breakdowns and unexpected stops is reduced.

  • Planned maintenance workflow:

The workflow for planned maintenance consists of several steps, which we will mention below:

  1. Identify the problem and create an action plan:
    Planned maintenance begins by specifying the scope of work to be completed. This is often done in response to a work order, although it may also be based on a recurring schedule. In both cases, accurate information is essential. The operator or supervisor who detects the problem must provide the correct information to the maintenance scheduler. This information includes details about the problem, the asset in question, and any additional problems that may be associated with it.
  2. Inspect the property and the location where the work will be done:
    After gathering all the necessary information and pinpointing the problem, the maintenance planner outlines the details of what needs to be done. This includes the scope of work, tools required and whether replacement parts or special materials are required. In addition, workplace inspection is very important.
  3. Order the necessary parts and prescribe a process to complete the job:
    It is also important to detail the procedures required to successfully complete the task. Things like shutdown procedures, access requirements, and safety precautions are all critical to completing a maintenance job, and it’s important that these considerations are identified during the planning phase.
  4. Add a priority level to the task sequence:
    Once the work is determined, it should be prioritized and any necessary materials should be ordered. Planned maintenance and repair should perform these tasks to ensure that the work is ready to be performed after the schedule. Assigned priority levels may be low, medium or high:

    • Low: Tasks that are not time sensitive or do not involve critical equipment.
    • Moderate: Time-sensitive preventive maintenance tasks performed on critical equipment.
    • A lot: emergency and urgent work.

    When assigning priority to maintenance tasks, planners must consider the importance of the equipment, the hazards these tasks treat, and the resources currently available.

  5. Schedule and complete planned maintenance and repair:
    Once the planning process is complete, the scheduling phase begins. The maintenance planner may do the planning or a separate planner may take over. Maintenance scheduling is a separate process from maintenance planning, but the two rely heavily on each other to ensure that preventive maintenance is carried out successfully.

  • Benefits of planned maintenance and repairs:

  1. Increasing the useful life of equipment: with regular repairs and preventing sudden breakdowns, the useful life of equipment and systems increases. This helps to save costs and time related to equipment repair and replacement.
  2. Reducing the possibility of sudden stoppage: By performing regular maintenance and repairs, the possibility of sudden stoppage of equipment is greatly reduced. This causes no interruption in activities and reduces negative effects on production or services provided.
  3. Improved performance and efficiency: Equipment and systems that are regularly maintained and repaired perform better and provide higher efficiency. By performing periodic repairs and necessary updates, hardware and software problems are fixed and lead to increased performance and productivity and reduced operational costs.
  4. Increased safety: Equipment is safer when it is regularly inspected and repaired. By applying security updates and regular testing, potential risks and mishaps related to equipment malfunctioning are reduced.
  5. Update and optimization: In the process of planned maintenance and repairs, there is an opportunity to update and optimize equipment and systems. These measures can improve the performance, efficiency and facilities of the equipment and bring more efficiency.
  6. Reducing costs: By doing planned repairs and regular maintenance, the costs of emergency and sudden repairs are reduced. Timely diagnostics and repairs fix small problems and prevent major and costly breakdowns.
  • Disadvantages of planned maintenance and repairs:

  1. Financial costs: planned repairs and maintenance incur costs. This includes the cost of repairs, spare parts, software updates and hiring a technical team. Some organizations may not be able to pay the necessary costs and this can lead to delays in repairs and reduced efficiency of equipment.
  2. Time Required: Performing planned maintenance and repairs requires time and effort. This process may require stopping and suspending normal business activities in order to carry out repairs, which can lead to project delays and reduced productivity.
  3. Complexity of management: planning and managing planned maintenance and repair requires careful planning and coordination between teams and activities. Coordination between schedules, provision of spare parts, hiring of technical team and management of financial resources can lead to complications.
  4. Need for proper planning: To carry out planned maintenance and repairs effectively, there is a need for proper and accurate planning. In case of lack of proper planning, repairs may be delayed and a favorable result may not be obtained.
  5. Risks due to errors: If repairs and maintenance are performed incorrectly or incompletely, serious risks may be introduced to devices and systems. Mistakes in repairs can cause further damage to the equipment and also increase the possibility of creating security problems.

In general, planned maintenance and repair has its advantages and disadvantages. Performing regular and correct repairs and maintenance can help to improve the performance and useful life of the equipment, but it requires costs, time and effective management.

  • Planned vs Unplanned Maintenance:

Obviously, the opposite of planned maintenance and repair is unplanned maintenance and repair, and it’s generally preferable to have a higher percentage of scheduled tasks. Unplanned work is done in two different ways, including emergency and so-called “free effort”.

  1. Emergency maintenance: Emergency maintenance often occurs when critical pieces of equipment break down. In most cases, maintenance teams want to minimize the amount of emergency maintenance required on their facilities.

To minimize emergency maintenance, maintenance teams can:

  • Implement an effective preventive maintenance program.
  • Improve existing PMs.
  • Use predictive analytics to focus on key maintenance tasks.

Tip: While preventive maintenance is generally preferred, sometimes disruptive maintenance is best for some non-critical assets, so unplanned work isn’t always a bad thing.

  1. Free effort maintenance: Any non-emergency maintenance work that is performed without prior planning is called free effort maintenance (also known as minor maintenance). Effortless tasks are usually simple and may not require much planning. However, sometimes maintenance technicians find and fix the problem without having the necessary tools or parts available on site. It can turn into the same types of waste as emergency work, such as:
  • Time taken to retrieve required equipment or replacement parts.
  • Time spent on LOTO procedures (hard when equipment operators don’t expect it).
  • The possibility of servicing equipment too much.
  • Task delays the completion of work orders that have already been scheduled.

As such, these tasks should be minimized. At the very least, it should be limited to low-risk tasks that don’t require much planning anyway.

Advantages and disadvantages of planned maintenance and repairs
  • Reducing planned maintenance and repair costs:

To reduce the costs of planned maintenance and repairs, you can consider the following measures:

  1. Regular and preventive planning: Regular and preventive planning for repairs and maintenance can help identify problems early and prevent serious breakdowns. By carefully planning the timing of repairs and maintenance, sudden and emergency costs can be reduced.

Solutions to improve the management of planned maintenance and repairs
  • The difference between planned and preventive maintenance:

Planned work can be divided into two main categories: preventive maintenance and planned maintenance.

Preventive maintenance and repairs includes all the work that is done not in response to a failure, but to prevent future failures.(Click for more information) while planned maintenance and repair as above It is work that must be done as a result of wear and tear where the equipment has not yet broken down and can still operate reliably until the maintenance department is equipped with the necessary materials, labor, and shop space to properly handle this. Start repairs.

The difference between planned and preventive maintenance
  • Ways to improve planned maintenance and repairs in facilities:

Planned maintenance and repair is most effective when done well. Some of the ways your facility can improve maintenance planning include the following:

  1. Improved event reporting: Any maintenance planning process is only as good as its information, which means event reporting should be as complete and up-to-date as possible. Whenever something happens in the facility, personnel should be encouraged to report it. report it, even though they may technically be guilty of it.
    One way to facilitate incident reporting in your facility is to make it a penalty-free process. This can be done by anonymizing work requests.
    Additionally, encouraging people in other departments to report breakdowns or equipment problems can help round out your incident report overall.
    Note: However, coordination between maintenance and operations is part of maintenance best practices, and the two departments must be in constant contact.
  2. Optimize existing PMs: Preventive maintenance and repairs offer higher cost savings but can still lead to waste if not optimized. Part of this waste includes time spent scheduling work that may not do anything. do not do
    Preventive maintenance that does not provide real benefits to your facility’s equipment should be eliminated. On average, this can mean eliminating about 30% of PMs, which can help your planners use their time more effectively.
    In addition, PM optimization can improve overall equipment reliability, which means less time is spent planning maintenance tasks after a breakdown.
  3. Control “free-effort” work: As mentioned earlier, free-effort work should either be carefully defined or minimized. If operators or technicians notice that there is a problem with a particular piece of equipment, they should be encouraged. to complete a work request or to repair it themselves.
    The exception to this is if the work does not require specialized equipment, tools or methods to complete. Typically, freelance work should be limited to tasks that can be done with the tools already at hand and that will take no more than half an hour to complete.
    In addition, focusing on key performance indicators can further encourage maintenance staff to limit unplanned work. Planned Maintenance Percentage (PMP) is the main key indicator to track in this case.
  4. Consider workers and backlogs: When your maintenance planners work depends on a variety of factors, including your current capacity and backlog. For example, if your crew consists of 15 technicians, each working 40 hours per week, your maintenance planner should plan for a total of about 600 work hours.
    Some of this work should involve recurring PMs, and the current backlog may fill some of that time as well. A large amount of work must be prioritized
  5. .Optimize MRO inventory: MRO inventory is the inventory that is required to assemble and sell the finished product but is not built into the product itself. For example, gloves are considered for packaging an MRO product. Even office supplies such as pens, highlighters and paper are also included in this group.
    Planned maintenance should consider MRO inventory items. If the MRO inventory is not optimized, it can mean that the scheduler has to factor in more hours per work order. Additionally, it may mean delaying some work until suitable replacement parts can be obtained.
    To support recurring PMs and overall maintenance efficiency, MRO inventory must be well organized and properly stored. The maintenance planner must also be aware of how the facility’s inventory is performing in order to calculate lead times and other related factors.
  6. Schedule recurring PMs through CMMS: Maintenance scheduling takes time. If this time can be reduced by automating some scheduling tasks, it can improve the efficiency and effectiveness of maintenance scheduling. help you
    Using a CMMS to automatically generate recurring PM tasks can reduce your maintenance scheduling workload while supporting reliability in your facility.(Click for more information about CMMS software)
  7. Track maintenance data: As you know, maintenance planning is only as effective as the information available. It is important to track maintenance data to ensure you have the information you need. Work order completion time, MRO inventory turnover, frequency of assigned tasks, and other criteria should be considered when planned maintenance and repairs.

As a result, planned maintenance is a key component of any facility’s maintenance process, and when well supported and properly implemented, can improve the overall quality of maintenance work.
