This thesis discusses how companies are now required to review their supply chains in order to be competitive in today's marketplace. Indeed, sudden external events that disrupt the smooth operation of corporate supply chains have been found to be increasingly common, leading the concept of agility, the ability to respond promptly to unexpected circumstances, to be incrementally popular. Agility translates into the concepts of process integrations, market sensitivity, virtual supply chain and network. In fact, today's challenges of companies no longer focus only on achieving a lean supply chain, through cost efficiency and the elimination of all unproductive processes, but also on the concepts of durability, robustness and scalability of all operations involved.
