As part of our work developing STEM, we evaluated a simplified air transportation model, where all individuals flow through a single hub, in comparison with a fully saturated model where all routes are modeled individually, and a "gravity" model where the probability of travel between airports is scaled by their physical distance.
Simplified, very simplified.
They investigated a simplified methodology for ranking transportation projects by using an integrated multiple criteria decision making process for prioritizing transportation projects when there are groups of decision makers with multiple opinions and biases [13].
The study may be regarded as one of the few studies to integrate an agent- or activity based model of travel demand, albeit admittedly simplified, with a fine-grained transportation network, a detailed traffic micro-simulation, and a project-level emissions model.
It requires less laboratory infrastructure and workload and allows for safer transportation of specimens and simplified survey logistics [ 23, 24].
This paper presents a simplified methodology for selecting an appropriate public transportation system by using an integrated multiple criteria decision making1 process.
One novel contribution is the modelling of the transportation of the pyrolysis products by a simplified "bubbling" mechanism and the quantitative description of the thermal and kinetic changes which occur during the pyrolysis process.
On Monday, having already been granted permission by federal regulators to relax the new emissions test when waiting times exceed 45 minutes, the state transportation commissioner ordered the central inspection stations to conduct only a simplified version of the test -- which measures fewer emissions -- through the end of the month.
In order to facilitate the understanding of the ion transportation in this complex system, a theory was also set up based on simplified Nernst-Planck equation and Donnan equilibrium, which helps to understand the experimental data.
Our simplified case study also excluded emissions related to tree planting, such as maintenance, tree production, transportation, planting, irrigation, processing of dead biomass and tree removal.
