Maintenance and Reliability

Importance of Maintenance

- To achieve a specific level of efficiency, quality and reliability.

Objective of Maintenance

(1) To maximize the useful life of the equipment
(2) To keep the equipment safe and prevent the development of safety hazard
(3) To minimize the frequency and severity of interruption into the operating process
(4) To maximize the production and operation capacity from the given equipment resources.

Type of Maintenance

(1) Breakdown Maintenace
(2) Preventive Maintenance
(3) Formal Preventive Maintenance - Work, Time, Opportunity and Condition Based.

Planning the Maintenance Programme

(1) List work
(2) List Frequency
(3) Prepared standart document and instrunction
(4) Prepared Plan
(5) Issue the instruction to the appropiate staff and contractors
(6) Record the plan when the work has been doned
(7) Carry out the post-maintenace audits & provide information for future policy making

Improving the Maintenance Capabilities

(1) well-trained personnel
(2) Adequate resources
(3) Ability and authority to do material plan
(4) Ability to identify the cause of breakdown
(5) Ability to establish a repair plan and priorities
(6) Ability to design way to extend the mean time between failure

What is realibility?

- is the profitability that a machine part or product function properly for a given length of time

- abilty to be fit for the purpose or function that a product or service has been designed.

- Importnt key function in many purchasing decisions.

Reliability improvement Techniques

(1) Use simple possible technique (KISS)
(2) Design fail-safe
(3) Use power design
(4) Use high reliabulity component
