Indicators screen on completion of an optimization

Basic principles

The route optimization process aims to set up visits to the highest possible number of customers, while respecting defined constraints and minimising cost. 

Once the two main phases of optimization have completed, or following a manual stop applied to an optimization treatment, a screen displays the economies that can potentially be made, showing the indicators in the context of two scenarios: 

  • scenario 1, standard utilisation, whereby a series of visits is submitted to TourSolver without any reference to an existing situation: this screen shows the indicators obtained by the route optimization treatment
  • scenario 2: if using evaluation mode, to compare an existing situation with the solution optimized in TourSolver, this screen then presents the gains obtained following optimization of an existing situation. In this second case, gains are calculated in comparison with the real situation as entered in TourSolver before optimization. These gains are therefore the real gains measured in relation to an existing situation. > Find out more about Evaluation mode.

Utilisation

Indicators screen - standard utilization

In the standard utilization scenario, the screen presents the best solution obtained after optimization and gives details of the series of indicators, classified by category. The screen presents the following information:

Visits

This section presents indicators on visits and operational progress on routes. The indicators are as follows:

  • Planned visits: total number of scheduled visits for the period
  • Unassigned visits: total number of unplanned visits (assigned to each route) for the optimized period
  • On time: total number of visits scheduled to arrive at the customer’s premises within the defined visit time window(s)
  • Late: total number of scheduled visits ending outside the defined visit time window(s)
  • Waits: total number of visits scheduled with a specific waiting time allocated before the visit, these waiting times being added to the planning
  • Early: total number of visits scheduled in advance, starting outside the defined visit time windows(s)
  • Lunch breaks: total number of lunch breaks for the optimized period
  • Drive breaks: total number of driving breaks for the optimized period, if these breaks have been enabled
  • Reloads: total number of reloading or unloading operations (depending on whether the routes are pick-up or delivery routes) required for fulfilment of all routes, if these are authorised for the optimized period
  • Non-optimal frequency: total number of visits for which the visit frequency is less than optimum, in the case where a visit frequency is defined for the optimized period

Drive

This section presents indicators on routes and driving required for the fulfilment of all these routes. The indicators are as follows:

  • Total distance: total cumulative distance to fulfil all routes on the optimized period.
  • Drive duration: duration of total cumulative drive-time to fulfil all routes on the optimized period, expressed in HH:MM:SS format (hours, minutes, seconds)
  • Planned tours: total number of planned visits on the optimized period
  • CO₂ equivalent: total quantity of CO2 equivalent released into the environment for all routes, on the optimized period
  • Used resources: total number of resources used on the optimized period, as compared with the total number of available resources subject to route optimization

Work

This section presents the indicators on the work times during routes. The indicators are as follows:

  • Total duration: total duration of all routes on the optimized period, expressed in HH:MM:SS format (hours, minutes, seconds)
  • Visit duration: total duration of visits on the optimized period, expressed in HH:MM:SS format (hours, minutes, seconds)
  • Wait duration: total duration of cumulative waiting times on the optimized period, expressed in HH:MM:SS format (hours, minutes, seconds)
  • Overtime duration: total duration of overtime hours when these are authorised, expressed in HH:MM:SS format (hours, minutes, seconds)
  • Duration of delays: total duration of late events on planned visits, ending outside the defined visit time window(s), expressed in HH:MM:SS format
  • Rest duration: total duration of break times (lunch breaks and driving breaks) when these have been configured, expressed in HH:MM:SS format (hours, minutes, seconds)

Quantity

This section presents indicators on quantities collected or delivered during routes, if these have been configured. The indicators are as follows:

  • Total quantity: total quantity collected or delivered on all routes for the optimized period
  • Average filling rate: average fill rate for all routes on the optimized period, establishing the relationship between quantities to collect/deliver and the capacities of resources for the quantity or quantities expressed

Costs

This section presents the various costs calculated for the optimized period, on the basis of costs configured beforehand for resources and visits. The indicators are as follows:

  • Total cost: total cost of all routes on the optimized period
  • Working cost: total cost of working time for all routes on the optimized period
  • Drive cost: total cost of travel times for all routes on the optimized period
  • Overtime cost: total cost of overtime hours for all routes on the optimized period, if these are enabled
  • Fixed costs: sum of fixed configured costs for all routes on the optimized period, if these have been configured
  • Overnight cost: total cost of nights away for all routes on the optimized period, if these have been enabled
  • Delivery cost: total visit time for all routes on the optimized period
  • Outsourcing cost: total subcontract cost for all routes on the optimized period, if this has been configured

Optimization results - evaluation mode


Where visits to be optimized contain the three fields needed in evaluation mode (Visit day, Resource name, Sequence number) the screen compares the results given for the existing solution - for which the costs, distances and durations have been calculated - with the best solution found by the route optimization. The screen presents:

  • on the left, values yielded at the time the real situation was calculated in evaluation mode  (Before optimization column)  
  • in the central pane, the value of indicators for the best solution found, obtained by theoptimization calculation (After optimization column) 
  • on the right, the gain obtained when comparing these first two columns. The cell displays in green where an improvement of the solution is obtained following optimization of the solution submitted to TourSolver.

The  button at the top left closes the window and displays the exportable route plan.
