Input JSON format

estimateCode

String → Identification of the input file.

algorithmBaseParamDto

Object → Basic data

platformDtoList

Array → Platform (i.e., pick-up point) info.

platformCode

String → Identification of the platform.

mustFirst

Boolean → Whether the platform should be first visited (bonded warehouse).

truckTypeDtoList

Array → Truck info.

truckTypeId

String → Identification of the truck.

truckTypeCode

String → Unique truck code.

truckTypeName

String → Unique truck name.

length

Float → Truck length (mm).

width

Float → Truck width (mm).

height

Float → Truck height (mm).

maxLoad

Float → Carrying capacity of the truck (kg)

truckTypeMap

Object → Map format of truckTypeDtoList, key is truckTypeId

distanceMap

Object →

• Key is two platform codes connected by “+”: e.g. “platform01+platform02”;
• Value is the float value of the distance (m) between them.

boxes

Array → Boxes (i.e., items) info.

spuBoxId

String → Identification of the box.

platformCode

String → Code of the platform the box is belonging to.

length

Float → Box length (mm).

width

Float → Box width (mm).

height

Float → Box height (mm).

weight

Float → Box weight (kg).

Output JSON format

estimateCode

String → Identification of the output file. Same as the input file.

solutionArray

2D-Array → Array of solutions. Each line is a solution, i.e. an array of trucks. Each element is a truck map.

truckTypeId

String → Identification of the truck. Same as the input file.

truckTypeCode

String → Truck code. Same as the input file.

piece

Integer → Number of boxes packed in this truck.

volume

Float → Total volume (mm^3) of boxes packed in this truck.

weight

Float → Total weight (kg) of the boxes packed in this truck.

innerLength

Float → Truck length (mm). Same as the input file.

innerWidth

Float → Truck width (mm). Same as the input file.

innerHeight

Float → Truck height (mm). Same as the input file.

maxLoad

Float → Carrying capacity of the truck (kg). Same as the input file.

platformArray

Array → Route of the truck, a list of platform codes.

spuArray

Array → Array of boxes packed in this truck.

spuId

String → Identification of the box. Same as the input file.

platformCode

String → Code of the platform the box is belonging to. Same as the input file.

direction

Integer → Direction of the box (100: box length is parallel to the truck length; 200: box length is perpendicular to the truck length).

x

Float → Coordinate of the center of the box (mm) in direction of the truck width, where the origin is the center of the truck.

y

Float → Coordinate of the center of the box (mm) in direction of the truck height, where the origin is the center of the truck.

z

Float → Coordinate of the center of the box (mm) in direction of the truck length, where the origin is the center of the truck.

order

Integer → Order of the box being packed.

length

Float → Box length (mm). Same as the input file.

width

Float → Box width (mm). Same as the input file.

height

Float → Box height (mm). Same as the input file.

weight

Float → Box weight (mm). Same as the input file.

Coordinate System

The coordinates of the center of the boxes are represented in the output files, where the origin coordinate system is the center of the truck, shown in the following graph 1.

The boxes can only be rotated horizontally, thus each of them only have 2 possible directions represented in the output files (100: box length is parallel to the truck length; 200: box length is perpendicular to the truck length), shown in the following graph 2.
