1、4.国际多式联运与集装箱运输 4.1 The Nature of Intermodalism Competition between the modes has tended to produce a transport system that is segmented and un-integrated. Each mode has sought to exploit its own advantages in terms of cost, service, reliability and safety. Carriers try to retain business by maximi
2、zing the line-haul under their control. All the modes saw the other modes as competitors, and were viewed with suspicion and mistrust. The lack of integration between the modes was also accentuated by public policy that has frequently barred companies from owning firms in other modes (as in the Unit
3、ed States before deregulation), or has placed a mode under direct state monopoly control (as in Europe). Modalism was also favored because of the difficulties of transferring goods from one mode to another, thereby incurring additional terminal costs and delays. Intermodalism originated in maritime
4、 transportation, with the development of the container in the late 1960's and has since spread to integrate other modes. It is not surprising that the maritime sector should have been the first mode to pursue containerization. It was the mode most constrained by the time taken to load and unload the
5、 vessels. A conventional breakbulk cargo ship could spend as much time in a port as it did at sea. Containerization permits the mechanized handling of cargoes of diverse types and dimensions that are placed into boxes of standard sizes. In this way goods that might have taken days to be loaded or un
6、loaded from a ship can now be handled in a matter of minutes. First Containership, Ideal-X, 1956 On April 26th 1956, the Ideal-X left the Port of Newark, New Jersey to the Port Houston, Texas, which it called 5 days later. It carried 58 35-feet (8 feet wide by 8 feet high) containers, along with a
7、 regular load of 15,000 tons of bulk petroleum. The 35 feet unit represented at that time the standard truck size in the United States. This first containership was converted under the initiative of Malcom McLean (1914-2001), a trucking magnate who saw the tremendous potential of containerization, p
8、articularly in terms of loading and unloading costs. McLean calculated that in 1956 loading a medium-sized ship the conventional way was costing $5.83 a ton. Comparatively, loading the Ideal-X was costing less than $0.16 a ton. The economic advantages of such a mode of transportation thus became cle
9、ar to the shipping industry. In 1960, McLean founded SeaLand, a major container shipping line, which was purchased in 1999 by Maersk, the world's largest container shipping company. The Ideal X carried containers until 1965, when it was scrapped. Since the 1960s major efforts have been made to inte
10、grate separate transport systems through intermodalism, which took place is several stages. What initially began as improving the productivity of shipping evolved into an integrated supply chain management system across modes. This involves the use of at least two different modes in a trip from orig
11、in to destination through an intermodal transport chain. Intermodality enhances the economic performance of a transport chain by using modes in the most productive manner. Thus, the line-haul economies of rail may be exploited for long distances, with the efficiencies of trucks providing flexible lo
12、cal pick up and delivery. The key is that the entire trip is seen as a whole, rather than as a series of legs, each marked by an individual operation with separate sets of documentation and rates. 4.1.1 Integrated Transport Systems: From Fragmentation to Coordination Factor Cause Consequence T

14、nt ownership Commodity chains Globalization Coordination of transportation and production (integrated demand) Networks Consolidation and interconnection Multiplying effect The notion of integrated transport systems received a lot of attention, particularly with improvements in the capacity, e
15、fficiency and reliability of freight transport systems. The conventional fragmented and sub-optimal freight transport systems have substantially been improved. A process of coordination of freight transport is taking place. Several factors can be pondered: (1) Technology Technology has been a pr
16、ime driving force. Containerization is without any doubt the most significant technological factor behind a more efficient coordination of transport modes. Innovations include modes, such as post-panamax containerships or double-stacking trains, but also intermodal equipment to handle significant tr
17、ansshipment demands. Hard (technical) assets require soft (management) assets. Information technologies have gone a long way to help improving the level of control over supply chains, which includes important aspects such as tracking shipments and managing fleets. The issue of e-commerce has particu
18、larly received attention. (2) Capital intensive sector Freight transportation is a capital intensive sector with high entry costs for the maritime and rail segments. The amortization of modes and infrastructures, particularly terminals, has to be spread over a significant time period, sometimes
19、over more than a decade. This environment is prone to risks and many potential investors are unwilling to commit capital for infrastructure projects. This a reason why the government has often been called to step in. Still, freight transport companies are dominantly private entities and must rely on
20、 capital markets to finance their ventures. If through a higher level of coordination with other elements of the supply chain a greater quantity and stability in utilization can be secured, capital costs can be reduced and financial returns improved. Thus, intermodal projects have potentially a lowe
21、r capital risk. (3) New forms of relationships Coordination also implies new forms of relationships between freight forwarders. This was favored by the deregulation of many transport modes in the early 1980s. The Aviation Deregulation Act (1979), the Staggers Act (1980), the Motor Carrier Act (1
22、980) and the Ocean Shipping Act (1984) are significant landmarks in this direction. It became easier for different transport operators to establish contractual agreements. Mergers / acquisitions within the same mode started to take place, mainly in maritime and rail transportation, but also modal an
23、d intermodal alliances. (4) Global commodity chains Globalization has permitted the emergence of a structure of production, often known as global commodity chains or global production networks. This structure requires a high level of coordination. It is thus expected that this production structu
24、re imposes a similar structure of distribution where coordination between modes and different transport systems is required. Under such circumstances, transport demand should increasingly be considered as integrated. (5) Networks Finally, integrated transport systems rely on the respective stren
25、gths of each transport networks. Since networks are expensive to build and operate, linking them promotes efficiency and a higher level of control. This can be considered as a multiplying effect where the efficiency of the whole intermodal network is higher than the sum of its parts. 4.1.2 Evoluti
26、on of Intermodal Integration It can be argued that three major paradigm shifts have taken place within containerized freight distribution systems: (1) Containerization of maritime transport systems. At first, the introduction of the container and its penetration within maritime systems took p
27、lace. This is particularly the case from the mid 1965s when standardization resulted in common container size and latching systems. The efficiency of port transshipments improved and inland services, dominantly relying on trucking, began to be established. Still, maritime services tended to be on a
28、point-to-point basis and between major ports. (2) Containerization of inland transport systems. Containerization moved inland, mainly in an attempt to improve the continuity already established within maritime transportation, particularly with the setting of pendulum services. The introduction
29、of doublestacking rail services in the mid 1980s required the setting and redesign of inland container rail terminals in North America. The adoption of the container in Europe gained momentum when an intermodal system started to emerge in the late 1970s. For example, the shift from conventional and
30、highly irregular barge services to scheduled and reliable container services in the second half of the 1970s gave impetus to a fast containerization process along the Rhine basin up to the main ports of Rotterdam and Antwerp. (3) Intermodal and transmodal operations. Since containerization has
31、expanded to cover maritime and inland transport systems, the next phase dominantly aims at improving its overall efficiency. This efficiency is mainly based in the reduction of the number of times a container is handled as well as the velocity at which intermodal and transmodal operations are perfor
32、med. Also, the growth in containerized shipments placed additional pressures on intermodal transport systems, which for the maritime segment resulted in the setting of offshore hubs. They mainly act as intermediary locations between major systems of maritime circulation/ Establishment of commodity c
33、hains. Inland transport systems accommodated a growing amount of traffic, which in many cases resulted in the setting of large inland freight distribution centers (inland ports). 4.1.3 Intermodal Transport Chain Four major functions define an intermodal transport chain: (1) Compositio
34、n. The process of assembling and consolidating freight at a terminal that offers an intermodal interface between a local / regional distribution system and a national / international distribution system. Commonly referred as the "first mile". Ideally, loads of freight coming from different supplie
35、rs are assembled at distribution centers so they can be forwarded to high capacity modes such as rail and maritime shipping. The dominant mode for such a process tends to be trucking as it offers flexibility and door-to-door services. Activities such as packaging and warehousing are also included in
36、 the composition process, which is closely linked with the function of production. (2) Connection. Involves a consolidated modal flow, such as a freight train or a containership (or even fleets of trucks), between at least two terminals, which takes place over national or international freight
37、distribution systems. The efficiency of a connection mainly is mainly derived from economies of scale, such as doublestacking or post-panamax containerships, coupled with an adequate frequency of service. (3) Interchange. The major intermodal function takes place at terminals whose purpose is t
38、o provide an efficient continuity within a transport chain. Those terminals are dominantly within the realm of national or international freight distribution systems, with ports (transshipment hubs) being the most notable example. (4) Decomposition. Once a load of freight has reached a terminal
39、 close to its destination, it has to be fragmented and transferred to the local / regional freight distribution system. Commonly referred as the "last mile" and often represents one of the most difficult segments of distribution. This function, which is linked with the function of consumption, domin
40、antly occurs within metropolitan areas and involves unique distribution problems also known as urban logistics. 4.1.4 Integrated Freight Transport Systems: Intermodal and Transmodal Operations From a functional and operational perspective, two components are involved in intermodalism: Intermodal
41、 transportation. The movements of passengers or freight from one mode of transport to another, commonly taking place at a terminal specifically designed for such a purpose. Transmodal transportation. The movements of passengers or freight within the same mode of transport. Although "pure" transmoda
42、l transportation rarely exists and an intermodal operation is often required (e.g. ship to dockside to ship), the purpose is to insure continuity within the network. The function of transshipment is of core importance in contemporary freight distribution as it is concomitantly an intermodal and a t
43、rans-modal activity. In integrated transport systems the time component has become increasingly significant. Since modal speed improvements tend to be marginal, it is at the terminal and with the function of transshipment that most of the time and cost benefits are achieved. Transshipment is more th
44、an an intermodal activity; that is movements between modes. It also concerns movements within segments of the same mode; modal transshipment. As commodity chains became more complex and longer the pressure on intermodal and trans-modal transportation has increased. In this geography of transshipment
45、s connecting different parts of the transport systems, freight markets and freight forwarders are interacting with increasing efficiency. Intermodal transshipments have received the bulk of the attention, particularly their port and rail terminals segments, as massive investments in those facilities
46、 were required to set global commodity chains. However, intramodal transshipments are comparatively uncovered, the main reason being that until recently they mainly took place within fragmented and regulated national transport systems. The three main transmodal dimensions include: (1) Transmodal r
47、oad Mainly takes place at distribution centers, which have become strategic elements in freight distribution systems. It is probably one of the few cases where intramodal transshipments can be combined with added value activities, such as labeling and packaging. Although distribution centers were
48、conventionally warehousing facilities in which commodities could be stored while waiting to be sold to customers down the supply chain, this function has substantially receded. Time constraints in freight distribution impacted on road based distribution centers, whose function is increasingly relate
49、d to transmodal operations and much less to warehousing. The true time-dependent intramodal facility remains the cross-docking distribution center. (2) Transmodal maritime Ship-to-ship transshipments mainly concerns intermediary hubs such as in the Caribbean, the Mediterranean or ship-to-barge a
50、ctivities. Although in many cases the containers are actually unloaded onto a temporary storage facility (commonly next to the piers), an off-shore hub is functionally a transmodal facility. They have emerged at intermediary locations by offering transshipment advantages in view of costs related to
