Maintenance Engineer Interview Preparation Guide

You should research a career path that would flow from the position for which you are interviewing and ensure that you emphasise the intention to master the demands of that position first.

Your answer should include: the way you listened to what the client had to say, confirmed an understanding of their concerns and subsequently took responsibility to resolve the situation by offering a solution, without going into too much detail about the specific complaint.

☛ 1) Starvation. Separating or removing the burning material from the neighbour hood of the fire.
☛ 2) Blanketing. Preventing the air flow to the fire.
☛ 3) Cooling. Lowering the heat created by burning materials.

The role of maintenance in maintaining asset value over time is getting more visible at the business level with the increase in its acquisition and maintenance costs.

various manufacturing systems are introduced along with their distinctive features that influence maintenance strategies and practices.

The main decisive factor for maximizing manufacturing asset value in terms productivity, reliability, cost, etc. is maintenance management, the body of the organization that is in charge of planning, implementing, controlling, and improving maintenance activities. Maintenance management is often considered as a centralized functional unit within the overall organizational structure in parallel with other functional units such as, production, Decentralized maintenance units is another common structure adopted by large organizations with multiple production units. The decision of adopting centralized or decentralized management structure is usually mad at the high management level taking into consideration, the size of the organization, the complexity of its operations, and the organization culture.

Because it is more legible than other styles.

The organizing responsibility of maintenance management includes:

☛ Job design
☛ Time standards
☛ Project management.

Job design involves defining for each major maintenance job, the work content, the method of maintenance the required skills and the needed tools.

Time standards are determined for major components of major maintenance jobs following the scientific approach. This helps in controlling maintenance tasks and efficient utilization of resources. It is also useful for planning and scheduling maintenance activities and forecasting workload.

Project management is used for optimizing and controlling major complex time consuming maintenance operations, such as shutdown maintenance projects for large plants. Critical Path Method (CPM) and Program Evaluation and Review (PERT) are common project management tools.

Some of the key objectives of TPM are:

☛ Focus and improve people management to minimize the targeted losses.
☛ Develop the policy, strategy and early management activities to ensure easy maintenance of the equipment.
☛ Develop the autonomous maintenance system to empower the production operators to take care of the conditions and effectiveness of the equipment.
☛ Develop a planned maintenance of the machine and equipment.
☛ Provide training and education to the operators and maintenance personnel to upgrade their equipment-related knowledge and skills.
☛ Establish safety practices and also prevent adverse environmental effects.
☛ Reduce the wastage of organizational resources.

The primary principles upon which RCM is based are the following:

☛ Function oriented. It seeks to preserve system or equipment function.
☛ Device group focused. It is concerned with maintaining the overall functionality of a group of devices rather than an individual device.
☛ Reliability centred. It uses failure statistics in an actuarial manner to look at the relationship between operating age and the failures. RCM is not overly concerned with simple failure rate; it seeks to know the probability of failure at specific ages.
☛ Acknowledges design limitations. Its objective is to maintain the inherent reliability of the equipment design, recognizing that changes in reliability are the province of design rather than maintenance. Maintenance can only achieve and maintain the level provided for by design.
☛ Driven by safety and economics. Safety must be ensured at any cost; thereafter, cost-effectiveness becomes the criterion.
☛ Defines failure as any unsatisfactory condition. Therefore, failure may be either a loss of function (operation ceases) or a loss of acceptable quality (operation continues).
☛ Uses a logic tree to screen maintenance tasks. This provides a consistent approach to the maintenance of all kinds of equipment.
☛ Tasks must be applicable. The tasks must address the failure mode and consider the failure mode characteristics.
☛ Tasks must be effective. The tasks must reduce the probability of failure and be cost effective.
☛ Acknowledges two types of Maintenance tasks and Run-to-failure. The tasks are Interval (Time- or Cycle-)-Based and Condition-Based. In RCM, Run-to-Failure is a conscious decision and is acceptable for some equipment.
☛ A living system. It gathers data from the results achieved and feeds this data back to improve future maintenance. This feedback is an important part of the Proactive Maintenance element of the RCM program.

It is a plane curve formed by a point moving so that the sum of its distances from two fixed points (foci) is constant and equal to major axis.
