1 Write short notes on the following:
Categories of maintenance activities
Answer : Types of Maintenance activities:
1. Breakdown maintenance
It means that people waits until equipment fails and repair it. Such a thing could be used when the equipment failure does not significantly affect the operation or production or generate any significant loss other than repair cost.
Mean Time Between Failures (MTBF)
Answer : MTBF (mean time between failures) is a measure of how reliable a hardware product or component is. For most components, the measure is typically in thousands or even tens of thousands of hours between failures. For example, a hard disk drive may have a mean time between failures of 300,000 hours. A desired MTBF can be used as a quantifiable objective when designing a new product. The MTBF figure can be
Advantages of a Sound Replacement Program
Answer : Advantages of a Sound Replacement Program
Now that we have understood the reasons for equipment replacement, let us now discuss some of the advantages of adopting a sound replacement program. A sound equipment replacement program practiced will accrue many benefits and afford advantages as detailed below:·
- It reduces the cost and
TPM implementation
Answer : Following are the steps involved by the implementation of TPM in an organization: Initial evaluation of TPM level, Introductory Education and Propaganda (IEP) for TPM, formation of TPM committee, development of master plan for TPM implementation, stage by stage training to the employees and stakeholders on all eight pillars of TPM, implementation preparation process, establishing the TPM policies and goals and development of a road map for TPM implementation (Prabhuswamy, et al., 2013).
2 Explain briefly the functions of maintenance planning. What are the benefits of maintenance planning?
Answer : Main functions
The Maintenance Service is entrusted with the overall responsibility for keeping the irrigation and drainage systems working in a satisfactory manner, within the limitations imposed by the initial design.
Similarly to the Operation Service, the main functions to be undertaken are:
– planning the maintenance activities;
3 What are the three stages in the lifecycle management of any machinery? Explain in brief the Life cycle management system.
A Listing of the three stages
Description of the stages with help of diagram(Life cycle management process), examples
Answer : Three satages :
1. Development
The development stage can be a protracted stage and will involve activities such as design, planning, costing, test marketing, etc. The costs are high, with no earned revenue (and thus it does not register as a stage on the diagram at Figure A1-1). Promotion for awareness may commence in advance of introduction of the product to the
4 Effective implementation of maintenance management in Quarta Technologies Quarta Technologies is a leading manufacturing company in Bhopal. It manufactures six million tubes a year. Each year, production shuts down for few weeks allowing capital investment projects and deep maintenance to be performed. These include process changes and a variety of maintenance activities are executed.
The Challenge
Ramping up to full production capacity after the shut sown was a slow process with attendant quality issues. The equipments used in this organisation were used for several years before it was either discarded or replaced with a similar new machine. From the time the equipment were brought, the production and maintenance personnel accumulated considerable knowledge about the equipment, the manner in which failures occur and the symptoms that it develops before a particular failure or malfunctioning happen. The organisation recognised an opportunity to reduce the quality costs of the annual shutdowns by planning and troubleshooting techniques.
The Solution
The organisation, worked with the plant leadership to improve project and risk management skills by introducing the common process. A progressive learning was done with respect to equipment usage and systematically captures many types of information and put to use. One method was to develop good trouble shooting mechanisms. This mechanism was a structured approach to identify the root cause of the problem that needs some correction when viewed from the maintenance. By successively checking on a set of condition about the equipment, several alternatives pertaining to the possible problematic areas will get eliminated and progressively narrows down to a few. Once this stage is reached, it is possible to conduct a detailed analysis to locate the problem and take corrective measures.
This helped the organisation to implement trouble shooting techniques which reduce the shutdown period and a total of 110 distinct maintenance projects and capital investments were managed. It also eliminated schedule conflicts that would have caused delays. This technique helped them to achieve their goals, ramping up faster to full production and improved team corporation.
What was the challenge faced by Quarta Technologies? What steps were taken by them to reduce it?
Answer : Challenge in implementation of maintenance management :
The Changing World of Maintenance
Over the past twenty years, maintenance has changed, perhaps more so than any other management discipline. The changes are due to a huge increase in the number and variety of physical assets (plant, equipment and buildings) which must be maintained throughout the world, more complex designs, new maintenance techniques and changing views on maintenance organization and responsibilities.
5 Write short notes on the following:
Routine maintenance
Answer : Defects that can be deferred without serious discomfort, inconvenience or nuisance to the tenant or another person or the long term deterioration of the building can wait the next convenient maintenance visit. Likewise, all other repairs, of no threat to the security or safety of the tenant can be with this 21 day period. Examples of normal or routine maintenance include:
- General joinery repairs
- Repairs to internal doors, floors and windows
- Repairs to walls (external & internal), brickwork and slate/tiles
- Repairs to gutters and downpipes
6 Explain briefly the twelve steps to be firmed up and practiced for successful implementation of the Autonomous principles in a production unit.
Answer : Combining roles of operators and maintenance specialists into a shared responsibility for maintaining equipment. The transition to full workplace ownership by operators is divided into seven steps, each followed by a management audit. Topics covered during the workshop include overview of TPM, 6 Big Losses, Preventive Maintenance and a seven step Autonomous Maintenance implementation.
The practical part of the workshop focuses on the first three steps of AM: Initial Cleaning, Elimination of the Sources of Contamination and Cleaning and Lubrication Standards. A pilot machine is used as a training ground to learn machine
