A transport planner with more than 20 years of experience, Mr. Ayzanoa analyzes waterborne freight logistics and develops operations/financial simulation and forecasting models to assess the feasibility and performance of ports, waterways, and intermodal systems. Drawing on his knowledge of mathematical modeling and information management, he designs, builds, and analyzes large datasets on macroeconomic indicators, commodity flows, port facilities, shipping patterns, and vessel costs to support modeling, forecasting, and planning.

Mr. Ayzanoa has worked extensively in the United States and Latin America and the Caribbean. He has examined the performance and productivity of transport operations and designed and developed simulation models to optimize intermodal transportation networks, including the physical components and interfaces of logistics chains for containerized and bulk cargo. He has contributed as well to several important projects in the port and shipping industry:

  • Expansion of the Panama Canal and its impact on liner container shipping and transshipment;
  • Evaluation of the construction plan for the Yangshan deep water port in Shanghai, the world’s largest container port;
  • Expansion and development of Port of Santos, Brazil, the largest port complex in Latin America; and
  • Development of long-term non-grain bulk commodity forecasts for the upper Mississippi.

Mr. Ayzanoa began his career at the National Institute for Ports and Waterways, the only academic and research center in the United States dedicated to performing technical and economic evaluations for the planning of maritime and river terminals and waterway navigation systems. Before joining Nathan Associates he worked for The Louis Berger Group as port planner and maritime systems analyst.
