This document outlines the principles and techniques of Availability Centered Maintenance (ACM) which aims to make engineered systems anti-fragile by modulating their behavior to optimize availability of time and resources. ACM combines breakdown, preventative, and condition-based maintenance strategies. It can reduce failures by 99% and maximize uptime by understanding system oscillations, wear, and flows based on history and patterns. Case studies show how ACM achieved zero failures for several companies. The document concludes by promoting a workshop to dynamically plan for applying ACM principles like observations, questioning, and creativity to achieve failure-free, anti-fragile systems.

2. Level 1 course
1. Problem & Case Studies
2. Strategies
3. Principles - Flow, Oscillation, Wear
4. Sensing system behavior & intentions
5. Techniques for improvement
6. Dynamic Plan -- Workshop

3. Definition of ACM
Responses aimed at modulating system
behavior of engineered systems for anti-fragility
to make time &resources available for
productive use.
Goal: Life style management

4. Why ACM?
More than 68% failures in a manufacturing
system are random in nature.
On average 26 days are used in recovering
overheads. Only 4 days to make profits.
In a manufacturing system as high as 40% of
the total production cost goes in maintenance

5. Case studies
1. Consolidated Fibres -- Zero failure - anti-
fragile
2. Vikram Cement -- Zero failure - anti-fragile
3. Tata Metaliks -- Zero failure - anti-fragile
4. Tata Metaliks Kubota Pipes -- Zero failure -
anti-fragile
5. Gujarat Cement Works -- Zero failure - anti-
fragile

6. Maintenance Strategies
1. Breakdown -- react to surface events -
fragile
2. Preventive -- effort to bring order & control -
fragility
3. Condition Based -- monitor & respond --
fragility reduced but not eliminated

7. Availability Centered Maintenance
Combine all 4 strategies for anti-fragility to
optimize cost & energy to improve productivity
through increased availability of time &
resources
What can be achieved?
Failures come down by 99%

8. Principles of ACM
1. Oscillations
2. Wear
3. Flow
The underlying principle is entropy

9. Sensing System Behavior
1. History.
2. Interdependent Interactions - evidence
based
3. Understanding Relationships, Patterns, No-
patterns, Causes

10. Techniques/Methods/Processes
(Summary)
1. Observations
2. NEME - Notice, Engage, Mull, Exchange
3. Why- Why?? -- systemic application
4. Creativity

11. ACM - Dynamic Plan for Anti-fragility
Workshop
