This page describes how to use dual crew management feature in Axiodis and corresponding key points.



Goals


Manage dual crew constraints for the system to be able to take into account if an attendant is necessary for the route realization and depending on different constraints  (products requirement, sites requirements, ...). 

This feature is mainly used in mill activity and can help the user to decide how many accompanist or drivers have to be taken into account during routes optimization.


Realization of transport plans, in which the solver can propose routes with double crews, on the basis of constraints related to the quantities on a route and / or sites.

  • Quantities constraints on a route
    Example: Starting from 7 tons of bagged products, triggering an escort


  • Site constraints
    Example: On this site, for delivery / collection of products packaged in bags, triggering an attendant.


All while taking into account :

  • The number of drivers / gui des available and the legation according to the composition of the double crew.
    Example: Propose a number of routes consistent with the number of drivers available


  • The composition of the double crew
    Example : driving time can be increased in the case of two drivers



Dual crew features must be activated in the licence to be used.


Data and constraints


Dual crew management constraints are available in "Data and Constraints" module :

  • "Products / Products families"  for triggering a double crew on a quantity constraint on a route
  • "Logistic sites / Logistic profiles" for trigering a double crew on a quantity constraint on site


Triggering a double crew on a quantity constraint on a route


  

This group of fields is used to indicate the limit from which, for a family of products, an attendant must be triggered on a route. This limit can be defined on one or more types of units :

  • Weight unit
  • Volume unit
  • Handle unit


Trigering a double crew on a quantity constraint on site


This group of fields is used to indicate if an attendant must be triggered on a tour.
  • Mandatory : Define that the presence of an attendant on the route is mandatory whatever quantities delivered / collected
  • Minimum limit : Define the limit from which, for a logistic site (and potentially for a corresponding product family), an attendant must be triggered for all the sites attached to this logistics profile. This limit can be set to one or more types of units (Weight unit, Volume unit, Handle unit).


Default value is blank (it means no specific limit).

Calculation parameters

Dual crew management parameters are available in "Data and Constraints" module, "Routes optimization profiles" screen :


Planning module


Some options are available in the global calculation screen about dual crew management :



In this part, can be precised number of drivers can be used and number of them as accompanist, with impact on the driving times (double crew as checked).

Can be also specified number of accompanists. Accompanists can't drive, so no impact on the driving time. 


  • « Number of drivers» : Define for the system and calculation the number of drivers available
  • « whose accompanist» : Define for the system and calculation the number of drivers that can be also considered as attendant
  • « Number of accompanists » : Define for the system and calculation the number of accompanist available
  • « Double crew » : Define for the system and calculation if attendant can also be considered as a driver (in this case, driving time can be increased).


A field can be displayed in routes grids to precise if the route need an attendant or not (and which kind of attendant) :

  • None
  • Attendant
  • Driver
