DAD is a digital application for the lifetime asset management of systems such as Power, Control and ICT.  So we begin by defining –

A set of interconnected devices performing the complex (often software based) functions required to operate an asset or plant.

System Information Model (SIM)
A set of interconnected digital objects describing the physical make up and functions of a system
The SIM is fundamentally different to the current system documentation.

SIM Documentation
A set of interconnected digital Objects describing the devices, connections and functions of a system Large quantity of individual files
Simply looking in the model brings you the data Finding data is labour intensive and error prone
Data can be edited instantly Editing, checking, and issuing documents is slow, labour intensive and requires special skills
Edits are clash detected No equivalent
Edits are recorded in the Object history No equivalent
In design, construction and operations all teams work on the same real system.  The SIM lets them work seamlessly. Design, construction and operations independently create documents.  There is no shared common view
The SIM acts as a “a single live stream of data” connecting teams along the life of a system The documentation is “a growing number of stagnant data pools”
Lifetime asset management is simple. No equivalent
Real work is recorded in the Object history No equivalent
The current state of the system is always available in the model No equivalent
Data improves over time as lessons are learnt Documentation always deteriorates over time

DAD replaces documentation with a digital model.  It brings huge benefits to the owners of power, control and ICT systems.

We call the digital model a System Information Model (SIM).  You can explore any real system in a SIM:

  • discover the functions it performs and how it does each one
  • start with cabling and probe down to individual terminations
  • start with fibre optic cable and probe to find the data carried in each fibre
  • find how to isolate a device and see what else may be affected

You can manage systems better for their life:

  • you can design a new system or “as build” existing ones by creating a SIM
  • you can specify and manage every work activity to deliver or modify a system
  • you answer site queries and to record site changes
  • you can record all tests, all repairs and routine maintenance on the system.

The SIM has a detailed history.   Users can be held responsible for their work. 

Lifetime cost and risks of ownership are significantly reduced.

DAD is both practical and proven.

DAD should be a first step for organisations working to converge IT/OT.
