NYTimes.com author Matt Hudgins writes about companies that are changing their “just-in-time” inventory model to a “just-in-case” strategy. This shift, due to storms like Hurricane Sandy and other disastrous events, has altered supply chains by adding additional distribution hubs, even in areas outside the traditional east and west coast seaport hubs. Just-in-time has been very popular since the 1990s and refers to keeping only small amounts of inventory on hand. Just-in-case planning “helps retailers keep merchandise on store shelves in the event a supply chain disruption affects one of the major distribution markets.”
