Initially,logistics was an activity divided around the While cycle time requirements substantially decreased supplying,warehousing,production and distribution from the 1960s to 1980s,this came at the expense of functions,most of them being fairly independent from growing logistics costs,notably inventory.From that the other.With the new organization and management point on,the major achievements were related to pro-subcontractors (Dicken and Thrift, 1992; Gertler, 1992; Hudson, 2001). The supply chain bundles together all this by information, communication, cooperation, and, last but not least, by physical distribution (Bowersox et al., 2000). Globalization means that the spatial frame for the entire economy has been expanded, implying the spatial expansion of the economy, more complex global economic integration, and an intricate network of global flows and hubs (cf. Dicken, 1998; Held et al., 1999; Knox and Agnew, 1998). Logistics thus developed against the background of long-term structural change in economy, technology and society affecting all major industrialized countries (IMF, 2001). These interrelated changes comprise sectoral and structural changes, mainly the rise of service economies, the increasing share of goods with high value and low weight, consumerism, the upcoming high tech and knowledge based sectors (Castells, 1996); they also include a new political framework, namely the policies of deregulation and liberalization that were effective for the US in the late 1970s and early 1980s, and for Europe since the introduction of the Single European Market in 1992 (Knowles and Hall, 1998). These policies are now also being adopted by many developing countries, with varied success. The principles of modern logistics can be traced back to Taylor (1947), the conceptual creator of fordism. Although his ideas were related to improving efficiency within the factory by organizing the worker’s tasks along an assembly line, the temporal dimensions introduced, such as sequence, duration, schedule, rhythm, synchronization and time perspective are of high significance to logistical management. What Taylor’s principles of management were able to achieve within the factory in terms of productivity improvements, logistics are able to achieve between elements of the supply chain: a system of integrated factories. A milestone that marked rapid changes in the entire distribution system was the invention of the concept of lean management, primarily in manufacturing (Womack et al., 1990; Harrison, 1997). One of the main premises of lean management is eliminating inventories and organizing materials supply strictly on demand, replacing the former storage and stock keeping of inventory. During the 1980s, the application of this ‘‘principle of flow’’ permitted the reduction of inventories in timesensitive manufacturing activities from several days’ worth to several hours. Much of these efforts initially took place within the factory, while supply and output flowed as batches from suppliers and to distributors. High rack storages, which later became automatically driven, or the internal movement of packages by flat robots were early expressions of logistical engineering. Initially, logistics was an activity divided around the supplying, warehousing, production and distribution functions, most of them being fairly independent from the other. With the new organization and management principles, firms were following a more integrated approach, thus responding to the upcoming demand for flexibility without raising costs. At the same time, many firms took advantage of new manufacturing opportunities in developing countries. As production became increasingly fragmented, activities related to its management were consolidated. Spatial fragmentation became a by-product of economies of scale in distribution. In the 1990s, with the convergence of logistics and information technologies, this principle was increasingly applied to the whole supply chain, particularly to the function of distribution. In some highly efficient facilities, the warehousing function went down as far as 15 min worth of parts in inventory. It is now being introduced in service functions such as wholesale and retail where inventory in stores are kept at a minimum and resupplied on a daily basis. Whereas contemporary logistics was originally dedicated to the automation of production processes, in order to organize industrial manufacturing as efficiently as possible, the subsequent modernization of logistics can been characterized by an increasing degree of integration. This trend was already on the way in the 1960s, as a key area for future productivity improvements (Bowersox et al., 1968). However, only with the implementation of modern information and communication technologies did this assumption become possible. They allow for the integrated management and control of information, finance and goods flows and made possible a new range of production and distribution systems (Abernathy et al., 2000). Step by step, and according to improvements in information and communication technologies, the two ends of the assembly line became integrated into the logistics of the supply chain: the timely supply of raw materials and components from outside, and the effective organization of distribution and marketing (Fig. 2). Flexible order and supply behavior is actually made possible by new technologies, primarily through the realtime exchange of information. Because of information and communication technologies, firms are able to order from point-of-sale, to adjust inventories to meeting demand (if not to eliminate them entirely) and to reduce redundancy almost totally. Features such as electronic data interchange (EDI), automated product flow in distribution centers (DCs) and warehouses, or the recent computer based tracing-and-tracking systems––which offer on-line control of shipped parcels via the web––are primary sources of enormous productivity gains over last two decades (Fig. 3). They still seem to be more important than innovations associated with the upcoming electronic commerce (Hesse, 2002a; OECD/ECMT, 2001). While cycle time requirements substantially decreased from the 1960s to 1980s, this came at the expense of growing logistics costs, notably inventory. From that point on, the major achievements were related to pro- 174 M. Hesse, J.-P. Rodrigue / Journal of Transport Geography 12 (2004) 171–184
