Consignment configuration

Consignment generation method

The consignments can be either purely synthetic or based on inspection records (e.g., Form 280 or AQIM). Configuration for the consignments is under the consignment key in the configuration file.

The generation_method key can be either parameter_based to generate synthetic consignments based on user-provided list of parameter values, or input_file to create consignments that match inspection records in a CSV file.

consignment:
  generation_method: parameter_based

Items per box

To create the boxes (of items) for each consignment, a value for items_per_box needs to be specified.

consignment:
  items_per_box:
    default: 200

Only the default value for items_per_box is required, but the user may also vary the value by transport pathway. For example, F280 and AQIM inspections records include information about the consignment pathway, which can be used to vary the value of items_per_box. The following is a configuration for generating consignments using a file called AQIM_sample.csv with items_per_box values that vary by air and maritime pathways. If the consignment arrives via an air pathway, one box will contain 200 items. If the consignment arrives via a maritime pathway, one box will contain 700 items. If the pathway is not air or maritime, a default value of 100 items per box is used.

consignment:
  generation_method: input_file
  items_per_box:
    default: 100
    air:
      default: 200
    maritime:
      default: 700
  input_file:
    file_type: AQIM
    file_name: AQIM_sample.csv

Notice that the values for items_per_box are under a default key. In the future, the simulation may support other keys to vary the number of items_per_box by commodity, origin, or port.

Synthetic consignments

The main keys for the parameter_based consignment generator are the min and max values of boxes. These values determine the range of sizes of consignments within the simulation. In the example configuration below, consignments will have 10 to 100 boxes per consignments.

consignment:
  boxes:
    min: 10
    max: 100

The generator adds origin, flower (commodity type), and port (where consignment was received). These are randomly selected from the lists specified in the configuration. These values are not currently used, but may be used to configure other parameters in the future (e.g., variable contamination rates by origin or inspection efficacy by commodity).

origins:
  - Netherlands
  - Mexico
  - Israel
  - Japan
  - New Zealand
  - India
  - Tanzania
flowers:
  - Hyacinthus
  - Rosa
  - Gerbera
  - Agapanthus
  - Aegilops
  - Protea
  - Liatris
  - Mokara
  - Anemone
  - Actinidia
ports:
  - NY JFK CBP
  - FL Miami Air CBP
  - HI Honolulu CBP
  - AZ Phoenix CBP
  - VA Dulles CBP
  - CA San Francisco CBP
  - WA Seattle Air CBP
  - TX Brownsville CBP
  - WA Blaine CBP

Create consignments to match an input file

To use a file of inspection records, set the generation_method to input_file and specify the file_type and file_name. Currently, the options for file_type are F280 and AQIM. Additional type of inspection data can be supported upon request, or you can format the inspection records in the same way as F280 or AQIM data, described below. The file_name is a path absolute or relative to the place where the Python program is running.

consignment:
  consignment_generator: input_file
  input_file:
    file_type: AQIM
    file_name: aqim_sample.csv

F280-based consignments

Consignments in the simulation can be based on real F280 records. In that case, a CSV file needs to be specified using the file_name key.

The CSV is expected to have the following columns:

  • QUANTITY which will be used as number of items,
  • PATHWAY which is used to determine the items_per_box value (case insensitive),
  • REPORT_DT is used for date,
  • COMMODITY as the flower (commodity type),
  • ORIGIN_NM as origin, and
  • LOCATION as port (where consignment was received).

The CSV file should be comma-separated (,) using double quote for text fields ("). The path is absolute or relative to the place where the Python program is running.

AQIM-based consignments

Consignments in the simulation can also be based on AQIM inspection records. In that case, a CSV file needs to be specified using the file_name key.

The CSV is expected to have the following columns:

  • UNIT which is used to specify the unit (must be items or boxes) used in QUANTITY.
  • QUANTITY which is used as number of items or number of boxes depending on UNIT specified,
  • CARGO_FORM which is used to determine the items_per_box value similar to PATHWAY in F280 (case insensitive),
  • CALENDAR_YR is used for date (YYYY only),
  • COMMODITY_LIST is used as the flower (commodity type),
  • ORIGIN as origin, and
  • LOCATION as port of entry (where consignment was received).

The CSV file should be comma-separated (,) using double quote for text fields ("). The path is absolute or relative to the place where the Python program is running.
