IoT-based systems will require a high level of decision making automation both in terms of infrastructure management and within the logic of the IoT applications themselves. Decision support systems (DSSs) are an essential tool in this context on account of their ability to enhance human decision-making processes with machine intelligence. The cognitive automation framework that we have created at Ericsson speeds up the development and deployment of intelligent DSSs by reusing as much knowledge as possible, including domain models, behaviors and reasoning mechanisms. The framework substantially reduces operational costs for IoT-based system management by enabling DSSs to make decisions about how to adapt to changes in their context and environment with minimal or no human interaction.

Internet of Things (IoT) applications transcend traditional telecom to
include enterprise verticals such as transportation, healthcare, agriculture,
energy and utilities. Given the vast number of devices and heterogeneity
of the applications, both ICT infrastructure and IoT application providers
face unprecedented complexity challenges in terms of volume, privacy,
interoperability and intelligence. Cognitive automation will be crucial to
overcoming the intelligence challenge.
The IoT is built on the concept of cross-
domain interactions between machines that
can communicate with each other without
human involvement. These interactions
generate a vast number of heterogeneous
data streams full of information that must be
analyzed, combined and acted on.

Specification of route(s) as graph(s), which includes vertices, edges
and edge-traversal costs (such as travel time and fuel spent).
Number of vehicles, vehicle IDs and vehicle capacity.
Number and ID of transportable entities (passengers, cargo).
The starting location of the transport agents
and transportable entities.
The transitions that transport agents can perform. Current
prototype implementation contains three transitions: pickup,
drop, and move-to-next-coordinate.
Which criteria need to remain constant for the transport service
to complete the specified route (usually this means that all
transportable entities are picked up and dropped off at specific
points along the route).
