Query: Simulation-based optimization of transportation costs in high pressure
  gas grid   Design, architecture and deployment details of a decision support system
engineered to minimize operating costs of compressor stations in a gas network
are presented. The system employs standard simulation software for pipelines,
combined with well known optimization routine for finding optimal station
control profiles in a repetitive way. A list of custom improvements is
presented that make the system capable and robust enough to perform the
optimization tasks. Implementation process is described in detail, covering the
case of handling extra optimality criteria postulated by the user. Benefits
from using the system and lessons learned are presented in the conclusions
section.
