7.2.6 CORRECTION MODULE
Technological progress and other effects are considered in the Correction
Module to narrow the gap between the statistics and the model calcula-
tions in the Main Module. The correction coefficient is the correction on
the basic assumptions in the other modules of SECA. These assumptions
which are either explicit or implicit include:
• In the Unit Consumption Module, the weighted average of unit consump-
tion changes without being affected by the technological progress.
• In the Productivity Module, the weighted average of unit productivity
changes without being affected by the technological progress.
• In the Main Module, the load factor is proportional to the machinery power
in unit area.
• In the Main Module, the average annual working hours of the other opera-
tion is constant the value of which remains unchanged over the year.
The correction coefficient coc can be calculated with the following
relationship:
(15)
The correction coeffi cient coc can be divided into two parts: techno-
logical progress coeffi cient tpc and the other effect coeffi cient oec. The
relationship between coc, tpc and oec is assumed to following equation:
(16)
Technological progress is typically accompanied with the reduction of
the unit consumption and the increase of the unit productivity. The rela-
tionship between tpc, tpc
uc
and tpc
up
is assumed according to Equation
(17):
