I currently work for supply chain and risk mitigation consultancy and have begun investigating online options to circumvent blockages at "major hubs". An example would be ogpnetwork.com. We use these to help our clients find suitable alternatives to established supplier, especially on a regional basis.
yes, Singapore and Asia are the well knowned logistic hubs but there are several other logistic hubs like Los Angeles, Chicago, Hong Kong, Tokyo, London and Paris—that form the backbone of today’s global supply chain.
