Model ID Codes

Model IDs comprise five components separated by underscores. Each component describes a characteristic of the model, its parameters, or the solution strategies used by the Google OR-Tools routing solver. A list of the possible component values and their meanings follows.

Component 1 – Public Library System Redesign Delivery Workgroup proposal and region number

  • possible values:
    • 'idlX' – 'idl' = Delivery Workgroup ideal proposal, X = region number
    • 'strX' – 'str' = Delivery Workgroup starting point proposal, X = region number

Component 2 – maximum route length parameter

  • possible values:
    • '08' = 8 hours
    • '10' = 10 hours

Component 3 – Google OR-Tools routing solver first solution strategy ("Routing Options | OR-Tools," n.d.)

  • possible values:
    • '01' = PATH_CHEAPEST_ARC
    • '02' = SAVINGS
    • '03' = SWEEP
    • '04' = CHRISTOFIDES
    • '05' = PARALLEL_CHEAPEST_INSERTION
    • '06' = LOCAL_CHEAPEST_INSERTION
    • '07' = GLOBAL_CHEAPEST_ARC
    • '08' = LOCAL_CHEAPEST_ARC
    • '09' = FIRST_UNBOUND_MIN_VALUE
    • '10' = AUTOMATIC

Component 4 – Google OR-Tools routing solver local search metaheuristic ("Routing Options | OR-Tools," n.d.)

  • possible values:
    • '01' = GREEDY_DESCENT
    • '02' = GUIDED_LOCAL_SEARCH
    • '03' = SIMULATED_ANNEALING
    • '04' = TABU_SEARCH
    • '05' = AUTOMATIC

Component 5 – vehicle capacity parameter

  • possible values:
    • '040' = 40 containers
    • '060' = 60 containers
    • '200' = 200 containers
    • '000' = capacity constraint removed
