Transportation [Ref. Bowersox page 311]The most visible of all functions of logistics and high contributor to logistics costTransportation functionality: Functions of transportation1. Product movement: * What is moved?Raw Material, Semi Finished items, WIP, Finished goods, packaging material, rejected material- movement is required up or down the supply chain
04/17/23 2
How is this done? What resourcesare used?Resources used by transportation: a. Temporal Costs - product is locked up during transit, hence inaccessibleb. Financial Costs- • several cost elements like Admn. Costs, salaries, maintenance costs are incurred. • Loss on account of product loss and damage also needs to be accounted for.• Cost of fuel for prime moverc. Environmental Costs - • fuel guzzler, eats up natural fuels
04/17/23 3
•67% of all domestic fuel used in the US is for transportation.• Creates congestion, air pollution and noise pollution. • Environmental cost is tangible and substantially intangible.• As transportation utilizes temporal, financial and environmental resources items must be moved only when product value is raised
2. Product Storage:
a. temporary storage when loading
and unloading is more expensive than
storage in vehicles
b. when storage space is limited
04/17/23 4
c. Vehicles kept moving on circuitous route. Product storage is expensive in a transport vehicle. But some times keeping overall cost in mind this is adopted.Principles of transportation1. Economy of scale• Bulk shipping brings down per unit transportation cost2. Economy of distancecost per unit kilometer decreases as the distance moved increases• Principles of transportation are fundamental in evaluating transportation strategies.

Participants in transportation decisions• Who are participants in most of the commercial decisions?• What makes transportation environment different?• Who are the participants in transportation decisions?• Who is a shipper?• Who is a consignee?• Who is a carrier?• The government & publicRoles and perspective of each partyShipper and consignee: • What do they want? Predictable and minimum transit time, minimum cost, specified pick up and delivery times,
04/17/23 6
zero loss and damage, timely exchange of information and invoicingCarrier:• What does he want? Revenue maximization and cost[labor, fuel and vehicle costs] minimization. Flexibility in pick up and delivery times to consolidate movesGovernment:• keen interest, flourishing national economy and transportation• Soviet Union and the break up• Hunger deaths in India Vs self sufficiency in food production
04/17/23 7
• Government control on carrier rates and licenses • Government owned carrier service• Government support - net work of roads, Airports and ATC, Ports and HarborsPublicWhat do public want?• Public as consumers trigger transportation activity by demanding products• Easy accessibility transport• Goods and services from all over the world at minimum cost
04/17/23 8
• Safety - accidents of various kind, oil spills• Environmental Concerns - atmosphere, water, noiseWhen these parties with separate and distinct interests interact transportation environment is createdWhat is transportation mode? Mode identifies transportation method or form• Rail, Road, Water, Air, Pipeline & Ropeway Impact of transport mode & transport time on costs of transportation• inventory
04/17/23 9
• transit capital• obsolescence• packaging• insurance - air, high insurance• breakageWhat constitutes Transport infrastructure[Transport elements]? What Factors affect the smooth functioning of transport?• Terminal facilities - well maintained loading unloading facilities, space for movement of vehicles, platforms, railway yards• Vehicles- trucks, ships or wagons. Their size, shape & speed
04/17/23 10
• rights of way- passage. Rails, roads, airways, limitations on speed, weight, height• Prime movers• Routs and sectional capacity• Transit Time• Weigh bridge facility• Distribution Pattern• Nature of product• Carrier organizations
04/17/23 11
What are various features of modes or modal characteristics? How do we measure relative importance of each mode?• System mileage, traffic volume, revenue, nature of traffic compositionRail Net Work:• Stands out in terms of tonne kilometres moved • 226 billion tonne kilo metres and 55.8% of total tonne kilo meters moved in 1982 in India• In US 37.4% of ton miles moved were by rail in 1990• Facing very stiff competition after II World War
04/17/23 12
• High capital investment due to right of way, switching yards, terminals but low operating costs• Focus on specific products than on broad range. Raw material extractive industries away from water ways.• Customer friendliness• Inter modal transport through alliances and acquisitions in US Development of Specialized Equipment • Enclosed tri-level automobile car• Cushioned appliance cars
04/17/23 13
• Unit trains - entire train carrying a single product that can go directly to the customer• articulated cars - flexible unit with extended chasis that can hold ten containers• double stack containers- containers in two levels• Advantages and disadvantagesRoad Transport• High flexibility and speed• ultimate mode of transport• rapid growth, post war• low capital cost as compared to railways• 179.2 billion tonne kilometres and 44.2% of total tonne kilo metres moved in 1982 in India
04/17/23 14
• Operating costs are higher• Ideal for small shipments over short distances• Highly labor intensive• Occasional fuel shortages• Disputes with government• Vehicle availability• Maintenance and spares costs and availability of service facilities• Octroi• Old MVA• Bad and unsafe road conditions• Restrictive permits
04/17/23 15
Developments in this area• Entry of several manufacturers of trucks• Trailers• National grid of highwaysWater transport• Sailing vessels, steamships-1800, diesel driven ships-1920• Deep water transport and navigable inland water transport• Domestic water transportation- lakes, rivers, canals• Main advantage of water transportation is its capacity to move extremely large shipments
04/17/23 16
• Deep water vessels-designed for ocean and lakes limited to deep water ports• Diesel towed barges- high flexibility, disadvantages are range of operation and speed• Inland water Transport is not used to its full potential in India although we have used Mechanized IWT since early 1800.• Lack of policy, clarity in thinking, receding water levels in the rivers, & tough competition appear to be the hurdles
04/17/23 17
PipelinesWhat is transported in a pipe line?• Liquids - oils, crude, petroleum products, In India, extensively used for transporting crude and petroleum products. More than 5,000 km of pipeline exists in India for crude and petroleum products• Slurries - coal slurry, iron ore, lime, huge quantity of water is necessary which is a concern for environment. In India pipe line is used for transporting iron ore.• Gases and vapors- natural gas, LPG, in India LPG pipe line is in existence
04/17/23 18
• Pulverized dry bulk material - cement by hydraulic suspensionMain features of this mode of transport• Reliable all weather means of transport• Low energy consumption• Pipeline being under ground space occupation is minimal• Pipe line operates all the time except when it is shut down for maintenance• No empty container or wagon to be brought back
04/17/23 19
• Highest fixed costs, right of way and laying of pipeline, and lowest operating costs[ not labour intensive]• Not flexible by nature. Pipe lines are stationary • Physical state of the commodity is a limitation.• This is mode of transport can release capacity of• Other modes for transport of essential commodities Rope ways & their suitability • hilly and otherwise inaccessible area• steep gradients • cause minimum ecological imbalance
04/17/23 20
• Point of supply and demand can be connected by shortest route.Air transport• Speed of transport is highest• Fixed costs are lower than rail or road or pipe line. But operating costs are highest• Air transport brings distant markets closer - perishables market in gulf countries• Overcomes the hassle and cost of setting up depots and service centers overseas• Full potential of peak seasonal demand can be taken• Moving entire facility & R/M to meet peak demand• Test marketing is easy. Products can be shipped directly from the factory

Freight rate structure
Principle of freight rates:1. Cover actual cost of transportationFactors influencing cost of transportationa. Fixed costs:• interest on capital• depreciation• insurance premium • administrative overheads and expenses on fixed facilitiesb. Semi fixed costs: • salaries of the staff• miscellaneous maintenance expenses directly related to running
04/17/23 22
c. Variable costs:• Cost of fuel and lubricants• Maintenance directly attributable to a particular trip• Damage to the vehicle and also the cargo. Eg. hilly roads, bad roads, war effected sea routesd.Vehicle utilization: Carrier likes to gain maximum mileage out of his vehicle• Run the vehicle at top speed to cover max. distance at min time Quote higher rates if following are not conducive to the above• Road conditions
04/17/23 23
• Terminal detentions [ congestion, formalities, loading/unloading etc.]• Obtaining a return load [market factors]• Nature of goods, hazardous, corrosive [liability, insurance]• Density, consignment light by weight• Stowability, shape and size of the product2. Traffic Bearing Capacity:• Value addition by transportation. Transportation cost should not upset the value added
04/17/23 24
3. Public use:• items to satisfy basic needs of common man should be moderately charged 4. Government Policy:freight rates are controlled by the state for• promotion of certain type of trade• development of certain type of industry• freight rates are hiked or depressed by state 5. Profit: freight rate should cover• costs of operation, capital investment and margin for reasonable return on investment
04/17/23 25
• entrepreneurial time and efforts• funds for future development of business Selection of Carrier• constitution of the carrier’s organization• business turn over• area of operation• branch offices or associates’ offices• strength of fleet• list of current clients, for# ascertaining reliability# nature and volume of business# normal transit time quoted by carrier# record of claims settlement by carrier

• reference from shippers banks, carriers’ association Inland Container Depots I C Ds are dry ports• connect major ports [able to handle container ships] to hinterland• facilitate customs clearance, export import formalities• ICD to be located after ascertaining export import potential and good road net work• serve as consolidation facility and should have handling equipment. Facility to group small consignments • goods transfer from road to rail and otherwise• increase the export potential of industries in the hinterland• decongest major ports
04/17/23 27
Transportation policy
Components of transportation decisions• Mode of transportationAir - most expensive, but very fastRoad - relatively quick and inexpensive, highly flexibleRail - An inexpensive mode for large quantitiesWater - the slowest but most economical for large overseas consignmentsPipeline - primarily for oil and gas• Route and network selection - route is the path the product takes and network is locations and routes along which a product can be shipped
