In the last decades of the twentieth century, there has been a significant expansion of the supply chain to international locations, particularly in the automotive, computer and clothing industries. This growth in globalization, as well as additional management challenges, have prompted specialists and academics to explore more about global supply chain management. Global supply chains have become a common way of organizing investment, production and trade in the global economy. The development of the supply chain depends on the establishment of theoretical and practical business models. Effective supply chain management uses models to ensure system improvements. Models represent effective tools that use simulations of real and potential processes. It should be stressed that the roles of suppliers must be fully and comprehensively explained at the beginning of each new relationship, with special measurable measures formulated, shared, discussed and agreed upon.
