The relentless growth in Mexico City’s aviation traffic has inevitably strained capacity development of its airport, raising thedilemma between the possible solutions. In the present study, Mexico’s Multi-Airport System is subjected to analysis by meansof multi-model simulation, focusing on the capacity-demand problem of the system. The methodology combines phases ofmodelling, data collection, simulation, experimental design, and analysis. Drawing a distinction from previous works involvingtwo-airport systems. It also explores the challenges raised by the Covid-19 pandemic in Mexico City airport operations, with adiscrete-event simulation model of a multi-airport system composed by three airports (MEX, TLC, and the new airport NLU).The study is including the latest data of flights, infrastructures, and layout collected in 2021. Therefore, the paper aims toanswer to the question of whether the system will be able to cope with the expected demand in a short-, medium-, and longtermby simulating three future scenarios based on aviation forecasts. The study reveals potential limitations of the system astime evolves and the feasibility of a joint operation to absorb the demand in such a big region like Mexico City.
Cut, cooled, packed, transported and traded all over the world, flowers represent a showcase of a worldwide integrated trade-logistics system. As one of the most perishable, vulnerable and time-critical products, speed is everything in harvesting, moving and trading of flowers. In the international trade of flowers and logistics of florticulture products, the Netherlands is the largest center of trade and logistics of flowers, taking a share of more than 40% in global cut flower export volume. When COVID-19 hit the world, this ever-moving system came to a full stop. What did this mean for the trade and logistics system? Which players were hit most? Did the crises change the system, just interrupt it or has it set the stage for developments already under way to strengthen and accelerate? This chapter presents and discusses the international position of the Dutch trade-logistics system as the most dynamic part of a worldwide flower industry. It sketches key trends in the industry over the last decade and draws a line towards possible post-COVID-19 scenarios for the worldwide flower industry and the international position of the Netherlands. The Dutch flower industry has shown incredible resilience to the external shock of COVID-19, but the crisis also has uncovered some weaknesses of the international flower industry. However, the chapter concludes that it is unlikely that these weaknesses will change the direction of developments in the sector, some of which already started to take shape in the 1970s. The chapter is based on pre-COVID-19 research and literature on the trade-logistics hub of the Netherlands, an analysis of trade and logistics data from around 2000 up to the first months of 2021, and existing economic scenarios for the flower industry and world trade.
