Shipping Network Design is an API to tackle the Liner Shipping Network Design
and Scheduling Problem (LSNDSP). The problem involves the design and scheduling
of a liner shipping network that minimizes operational costs, while maximizing
revenue from the shipping of commodity demand between ports. The network design
subproblem focuses on determining the set of ports serviced by the network, the
number of vessels to be allocated to each route, and the routes to be taken by
the vessels. The scheduling subproblem, is concerned with developing sailing
schedules for the vessels, considering factors such as sailing time between
ports, cargo loading, unloading and transshipment times, and the demand for
transportation between different ports.
API overview
The input of the API is a request that describes
Ports with vessel class specific costs and restrictions
Vessel classes with capacity and fleet size
Leg candidates corresponding to possible connections between ports for a
given duration and vessel class compatibility
Demands between ports, with freight rate and optional transit time
restrictions
(optional) Existing vessel services
For details about the input request, refer to the request section in the
REST reference.
The output of the API is a response providing vessel services and
commodity demand paths. Vessel service schedules are defined as a sequence
of leg candidates with a given departure time. Each vessel service has an
assigned vessel class. Commodity demand paths are described as sequences of
vessel service legs.
For details about the output response, refer to the response section in the
REST reference.

It determines optimal port service, vessel allocation per route, and vessel routes. Inputs include ports, vessel classes, possible port connections (leg candidates), and inter-port shipping demands. The API outputs vessel service schedules, which detail sequences of legs and departure times for specific vessel classes, along with commodity demand paths that describe how demands will be routed across those services. Users can get API access by following instructions in setup page.\n"]]
