Some other algorithms are based on the features extracted from retinal images, and usually, the implementation time of these methods is low.
Consequently the average cost decreased because fixed costs spread out horizontally across the number of subjects served every year and vertically along the implementation time.
Thus, test algorithms can be implemented on GPP, reducing the implementation time and allowing tests with real transmissions using actual hardware transceivers.
This will drastically bring down the implementation time and cost making it practically and economical viable.
From the COCOMO II project [8], it is known that the relationship between the implementation time and the complexity measure (in their case lines of code, LOC) can be expressed as a power function with a weak slope.
The implementation time was indicated in only one project.
Therefore, in order to overcome existing analytic weaknesses, we propose a model that optimally subdivides a predetermined rail transit line into sections for phased development and optimizes the implementation times of those sections over a planning horizon.
However, as stated previously, estimating the size does not always give an accurate indication of the implementation difficulty, and the necessary implementation time.
This IP calculate also the urgency criterion of critical tasks according to the implementation and the execution time of their successors.
For each task the implementation PE and the execution time are fixed, so the role of this IP is to calculate the start time of the task and to define its state.
