Questions and Answers
What is the definition of availability?
Availability is the ability of the system to perform required functions over the life of the system. It is the probability that a system is not failed or undergoing a repair.
How is availability related to system reliability and maintainability?
Availability is the parameter that translates system reliability and maintainability characteristics into an index of effectiveness.
What are the elements of availability?
The elements of availability include total intended utilization period, total corrective (unscheduled) maintenance time per specified period, and total preventive (scheduled) maintenance time per specified period.

Study Notes
Definition of Availability
- Availability refers to the ability of a system to perform its required functions throughout its lifespan.
- It represents the probability that the system is operational and not under repair.
- It assesses whether equipment is operational when needed, emphasizing immediate usability.
- Acts as a metric connecting system reliability and maintainability to overall effectiveness.
Elements of Availability
- Availability is fundamentally time-related, involving multiple metrics.
- Total Intended Utilization Period (TT): Represents the complete timeframe expected for equipment usage.
- Total Corrective Maintenance (TCM): Encompasses all unscheduled maintenance time during a defined period, crucial for assessing unplanned downtimes.
- Total Preventive Maintenance (TPM): Accounts for scheduled maintenance efforts, which help mitigate potential failures and ensure reliability.
Importance of Availability Assessment
- Evaluates the operational state of equipment, aiding in strategic maintenance planning.
- Facilitates understanding of the balance between uptime and downtime across equipment lifecycles.
- Assists organizations in improving maintenance strategies to enhance overall system effectiveness.
