What is Fleet Management?
What is Fleet management?
Fleet management entails overseeing and coordinating vehicle operations to ensure the efficient delivery of services.
Our focus
Balance operational uptime with maintenance cost efficiency
Reactive
Preventative
Cost
Downtime penalty
Cost as a function of Risk
- How likely
- Penalty
Risk as a function of reliability
- Failures over time
RO Data
- Repair description
- Associated costs
Models
- Univariate
- Univariate Weibull
- Multivariate
- Cox Proportional Hazards
Simplicity > Complexity
| Penalty | Risk 30k | Risk 60k | Risk 90k | |
|---|---|---|---|---|
| Transmission | $ 300 | 10% | 33% | 57% |
| Population | 30k | 60k | 90k |
