1. Task 1.2 Hardware and equipment definition
The existing and possible new technical solutions are so many that we
have to work from the end user upwards. This is the reason why the
complete definition of T.1.2. Hardware and equipment definition
(KESLA) is mainly based on the results of WP1- T.1.1.: Users and
System requirements (ITENE). Questionnaire directed to:
•
•
•
•
•
•
Forest owners
Harvesting contractors
Transport companies
Mill companies
Biomass processing companies
Others…

…and system analysis:
The integration of all information described above will allow for the analysis.
The integration of all data in one single system is the key to analyse and provide with
valuable information along the procurement chain. The combination on the described
data will provide more information and that information we will have to decide how and
which
information
is
transferred
(Bluetooth,
wireless,
by
colour
marking, print, USB, other…) MHG expertise is very important here. Systems to be
