Types of maintenance:
1) Run to failure maintenance.
2) Preventive maintenance.
3) Remedial maintenance
4) Improvement maintenance
5) Predictive maintenance
6) Other types
Run to failure maintenance (RTF): machine or facility need a replace or repair action after its failure to get it back to its working condition. In run to failure maintenance the maintenance policy is to do maintenance only when equipment or machine failed. Run to failure maintenance can be thought as of the strategy that is designed to lower the maintenance cost. The cost for this type of maintenance is low as compared to other maintenance.
Example of run to failure maintenance is: a light bulb a light bulb is allow to run till its failure whenever it fails the new bulb

• Straight forward: in other words easy to understand because the arrangements are effortless so it is easy to understand and implement.
Disadvantages:
• Erratic: as it requires replace or repair when it fails so it’s unpredictable that when machine parts/operators requires repair.
• Expensive: All expenses connected with this system should be considered when it is actualized. These expenses incorporate production expenses and breakdown costs, in addition both direct and indirect costs.
• Inventory cost: the maintenance need to keep the spare parts in inventory in order to repair the facility when it fails.
Preventative maintenance: it is plan maintenance aimed at prevention of breakdown and failure. Its aim is to prevent the breakdown. It designed to enhance the reliability of the equipment as by preventing it from failure.
It’s difficult to manage as compared to run to failure maintenance because it requires the planning schedule.
Preventative maintenance is further classified into following types:
1) Running maintenance
2) Routine

It is further classified into three types:
1. Design out maintenance
2. Service maintenance
3. Shutdown improvement maintenance.
i. Design out maintenance: it is aimed at applying the improvement and modifications in an equipment in order to eliminate the failure cause. It is designed in such a way to eliminate the use of maintenance. ii. Engineering service: it is a type of maintenance concerned with rearranging, modifications of facilities. iii. Shutdown improvement maintenance: improve the maintenance activities while the production line is completely shut down.
Predictive maintenance: it is a type of maintenance which identify the problems in physical condition of the equipment in order to minimize the risk of failure and increase the reliability of equipment.
It is further classified into two types:
1) Condition based maintenance.
2) Statistical maintenance.
a) Condition based maintenance: Condition based maintenance (CBM) monitors the actual condition of the equipment and decides when maintenance required. This type of maintenance is performed when equipment cannot fully

Fault tolerance is the property that enables a system to continue operating properly in the event of a failure.
MillerCoors can establish the context as generalized machinery failure. Through identifying the risk, MillerCoors can identify the source of machinery failure could happen anywhere from production machinery to delivery equipment, with the causation arising from mishandling of machinery, general wear and tear or even sabotage events. Consequently, failures in machinery could not only create operational delays, but would cause financial loss and increased liability. Depending on the age and the extent of personnel training, the likelihood of machinery failure would vary drastically within the organizations and between brewery operations. To properly evaluate machinery failure risk, all eligible assets should be broken down into different levels, based in the type, age and complexity of the machinery. To reduce the risk and loss potential, MillerCoors, should instill performance measure to within policies and procedures to makes sure equipment is regularly inspected. In addition, the organization should focus on provided proper and frequent training to make sure personnel are educated in the use of the organizations machinery. Therefore, through the risk management process MillerCoors can provide treatment to reduce the effects of machinery
High Maintenance is a web series which allows glimpses into people’s everyday lives in a diverse and insightful way. It is available on the website ‘Vimeo’, with four of the ‘cycles’ (seasons) available for free and the fifth one for a low price, with the episodes varying in length (usually shorter than 15 minutes). The series follows the character known as ‘The Guy’, a marijuana dealer who delivers to these people’s homes. Each episode features a different person, couple or group and “The Guy” acts as the audience’s ‘window’ to each, although he often features very little in each episode. This essay analyses High Maintenance through the episodes of “Rachel”, “Helen” and “Matilda” and discusses how the episodes uses space while linking it

Preventive Maintenance Checks and Services (PMCS) means systematic caring, inspecting, and servicing of military equipment to keep it in good condition and to prevent breakdowns. The operator of the vehicle mission is to be sure to perform PMCS each time he/she operate the vehicle. Always do the PMCS in the same order, so it gets to be a habit. Once you've had some practice, you will quickly spot anything wrong.
Not only can preventative maintenance help make your appliances last longer, but it can also help improve the safety in your home. Performing this type of maintenance is a great way to prevent home fires, which are commonly caused by faulty wiring. Identify

For example: with the increase of the number of products produced, the cost of operating a machine also increase. Second we have batch level costs which is associated with batches; producing a multiple units of the same product that are processed together is called a batch. The third type is product level costs which arise from any activity in order to support the production of products. The fourth and the last type is facility level costs, this costs cannot be determined with a particular unit, product or batch; this costs are fixed with respect to batches, products and number of units produced. A single measure of volume is used for allocating costs to each service or product in traditional method for example: direct material cost, machine hours, direct labor cost and direct labor hours. A cost driver is an activity that generate costs, it can be generated by two types of costs the first is a particular machine 's running costs where the costs is driven by production volume as machine hours; the second is quality inspection costs where the cost is driven by the number of times the relevant activity occurs as the number of
These procedures and practices are used both by GM and by their vendors. The policies vary from layered inspections, statistics, process failure modes, effects analysis and control plans (Drew, 2011). All quality measures produce a graded system of quality management utilizing quality tools. An example of quality control test is that of speedy response wherever dilemmas are resolved quickly and immediately throughout visual management. Individuals responsible for specific tasks are kept accountable for some corrective actions that may subsist. What General Motors did was ignore this quality measurement when it was dealing with the problems of the Chevrolet
For example if a company purchases machinery for the production of a certain product the management must take under consideration the equipment’s life cycle, meaning that this machinery has a certain period of time in which it can contribute to the production before it becomes useless. Useless in a sense of a newer machine will be invented in some years which will be probably faster or more capable to produce better quality. The time factor of course always varies depending on the asset. For example the usefulness of a computer may be three years before it needs replacing, as for a building may be fifty years.

As the development of aviation industry grows, more and more aircraft crashes occur. There are many reasons that lead to aircraft crashes, but one of them, is because of improper aircraft maintenance. Why is proper aircraft maintenance so important? Proper aircraft maintenance is critical in order to keep the aircraft can function properly, every aircraft part is in good condition and ensure the safety of pilots and passengers. Proper maintenance has many parts. The most common part is inspections, which pilots do them every day; the main part is overhaul and repair of an aircraft; and maintenance documentation is another important part of aircraft maintenance which improper maintenance documentation has caused many incidents.
