Modern Supply Chain The city where I was born was more like a company, since more than half of the population was composed of employees from one giant corporation: the largest domestic automaker. I used to take overlook at the whole city from the top of the tallest building in town . More than 30 Large-scale plants interspersed among the city. What I could see was the endless transportation, What I couldn’t see were the countless ever-running product lines. At that time, I had been thinking about how the city ran? How the corporation ran stable? How the thousands categories of components head off accurately to every single product line in different plants and at the end into a complete car from assemble line? 15 years past. The modern supply chain has ridden a remarkable wave of innovation in which new ideas has been springing up all the time. ___The organization system of material and manpower that make the chain work has also been significantly reformed. The concept of supply chain has been broaden and deepen. From the previous taken-as-internal procedure which is known as “raw material procurement-production transformation-sale”(or is this one better?：From the previous “raw material procurement-production transformation-sale” which was simply confined to a internal procedure) to the latter value added chain, where the end user and consumer were given highly concern(attention？focus？) and were adopted into supply chain management. __Thereafter_, the global e-business under up-to-date SC conception, in which the Inventory-Cost management has been unprecedentedly take into consideration. Such an evolution is the inevitable consequence of the extraordinary focus on efficiency. People explore the interlocking chains of supply and demand, from the simplest steel screw to the sleekest brand-new car. The manufacture under the modern SCM has greatly fueled the local economy, it also has shaped this city and reshaped who we are and what we make .Yet where will the ruthless competition and relentless innovation lead us?
