APS allows users to input discrete Work Schedule Delays as well as Time Usage Factors which affect availability, utilisation and rate.
Loaders / Other Equipment
Loaders, diggers, drills, etc. each have 4 different factors which affect agent capability.
Unplanned Availability (UPA) - Affects available hours
Use of Availability (UA) - Affects Engine On hours
Operator Efficiency (OE) - Affect Productive hours
Productivity Factor (PF) - Affect Productive hours
Note: These factors are applied after Work Schedule Delays are taken into account.
If an agent has 6 hrs of Work Schedule Delays in a 12 hr period, then the above factors apply to the remaining 6 hrs of the period.
Delays
Delays are discrete events which can be recurring or once off.
There are 4 possible delay states:
Available & Engine On: Relocation, Wall Scaling
Available & Engine Off: Meal Break, Shift Change
Not Available & Engine On: Maintenance Live Testing
Not Available & Engine Off: Service, Fuel Up
| Info |

Order of delays is important. If the overlapping delays occur, then the higher ranked delay takes precedence and will be reported. |
Calendar Fields
| Note |

Scheduled Delays include ‘Do Nothing’ delays which occur if the agent is idle for any reason other than a specified delay. |

Direct Utilisation | UPA * UA * OE * PF |
Engine Factor | OE * PF |
Agent Working Calendar Hours | Calendar Hours - Scheduled Delays |
Available Hours | Agent Working Calendar Hours * UPA + Scheduled Delays Marked as Available |
Engine Hours | Agent Working Calendar Hours * UPA * UA + Scheduled Delays Marked as Powered |
Productive Hours | Agent Working Calendar Hours * Direct Utilisation |
Report Fields
Field | Calculation |
|---|---|
Agent.Availability | Available Hours / Calendar Hours |
Agent.Utilisation | Productive Hours / Calendar Hours |
Agent.Productive Rate | Nominal Rate * Direct Utilisation |
Examples:
Period 1: Has a 6 hr delay where the machine is Available and Engine is Off.
Period 2: Has a 6 hr delay where the machine is Not Available and Engine is Off.
Period 3: Has 2 delays: 3 hr Available and Engine On, 3 hr Not Available and Engine On.
Calendar Results
Period 1
Agent Working Calendar Hours = 12 - 6 = 6 hrs
Available Hours = 6 * 0.9 + 6 = 11.4 hrs
Engine Hours = 6 * 0.9 * 0.9 + 0 = 4.86 hrs
Productive Hours = 6 * 0.6561 = 3.94 hrs
Period 2
Agent Working Calendar Hours = 12 - 6 = 6 hrs
Available Hours = 6 * 0.9 + 0 = 5.4 hrs
Engine Hours = 6 * 0.9 * 0.9 + 0 = 4.86 hrs
Productive Hours = 6 * 0.6561 = 3.94 hrs
Period 3
Agent Working Calendar Hours = 12 - 6 = 6 hrs
Available Hours = 6 * 0.9 + 3 = 8.4 hrs
Engine Hours = 6 * 0.9 * 0.9 + 6 = 10.86 hrs
Productive Hours = 6 * 0.6561 = 3.94 hrs
