South African Logistics and Freight Transport Systems

South African Economic Growth and Logistics

Business Logistics is defined as the combination of materials management and physical distribution. It requires a balanced system to manage various flows:

• Heavy Inbound: Managing incoming raw materials.
• Heavy Outbound: Managing the distribution of finished goods.
• Reverse Logistics: Handling returned goods and waste disposal.

It is essential to distinguish between physical flow and information flow, such as the sequence of order, confirmation, announcement, and reply via Electronic Data Interchange (EDI).

Peculiarities of Transport System Elements

• Fixed and Mobile Capital: Infrastructure and transport means are capital intensive with limited alternative uses.
• Economies of Scale: Larger volumes lead to lower unit costs.
• Market Structure: Ranges from monopoly to intense competition.

Transport Service Characteristics

• Complex service structures with derived demand.
• Demand is often unevenly spread over time.
• Services are non-storable.

Logistics Cost Contributions (2013 Data)

• Transport: 59.8%
• Inventory Carrying Costs: 13.5%
• Warehousing: 14.3%
• Management/Administration: 12.5%

Transport Modes and Selection Criteria

Choosing the best mode or combination of modes is vital for logistics coordination. Key criteria include:

• Speed and Flexibility
• Reliability and Reachability
• Ease of Use and Information Availability
• Image

Primary Modes: Deep sea, short sea, rail, inland shipping, road, air, and pipeline.

Distribution Decisions

• Consolidation: Placing a warehouse close to markets to combine smaller units from different plants.
• Break-Bulk: Breaking large volumes into smaller individual shipments.
• Mixing: A combination of consolidation and break-bulk.

South African Economic Context

South Africa's economic activity is highly skewed, with inland centers like Gauteng often being larger than port cities, contradicting traditional theory. Key challenges include:

• Density Issues: Markets are far apart, and Gauteng is distant from ports.
• Ton-km: South Africa requires the distribution of 348 billion ton-km to maintain its economy.
• Corridor Transport: Long-distance movement between industrial centers (e.g., Durban to Gauteng).
• Primary Transport: Exporting mining commodities located far from ports.

A 1% reduction in logistics costs could save South Africa approximately R3.39 billion per annum. Currently, the lack of a well-thought-out freight strategy and geographical distance from major partners (UK, Europe, USA, Japan) places the country at a disadvantage.

South African Trade and Maritime Links

Bulk exports, primarily raw materials like coal and iron ore, represent the main cargo volume. In 2015, 75.4 million tons of coal moved through Richards Bay and 59 million tons of iron ore through Saldanha.

• Rail: Used for the inland transport leg of bulk commodities.
• Liner Trades: Global trends favor integrating port and overland links.
• Container Market: South Africa handled 4.83 million TEUs in 2014, accounting for less than 1% of global trade.
• Modal Split: Since deregulation, the split has shifted heavily in favor of road transport over rail.

Regional Integration and Hubs

Africa hosts 15% of the world's population but only 2.4% of global GDP. Strengthening relationships with neighbors is essential:

• Landlocked Countries: 15 countries in Africa face geographical disadvantages.
• Corridors: Efficient corridors are required for international trade.
• Regional Hub: South Africa aims to be a regional hub. With the exception of Mauritius, South Africa has the lowest logistics costs in Africa.
• Port of Ngqura (Coega): Designed to accommodate ships up to 12,500 TEUs.

Transport Fundamentals

An effective transportation system fosters greater competition, economies of scale, and reduced prices, leading to a higher standard of living.

Service Characteristics

• Price: Line-haul rates plus accessorial charges.
• Average Transit Time: Door-to-door or terminal-to-terminal duration.
• Transit Time Variability: Differences caused by weather, congestion, or stops.
• Loss and Damage: A primary customer service condition.

Intermodal Transport

Logistically linked movement using two or more modes (e.g., Trailer-on-Flatcar or Container-on-Flatcar) to benefit from the advantages of different modes.

Agents and Small Shipment Services

• Freight Forwarders: For-hire carriers that consolidate small shipments.
• Shippers Associations: Non-profit cooperatives for lower shipping costs.
• Transport Brokers: Intermediaries providing information on rates and routes.

International Transportation and Trade Zones

Water carriers dominate international trade. Key considerations include documentation, protective packaging, and insurance.

Foreign Trade Zones (FTZ)

Duty-free areas where goods can be stored, processed, or repacked without incurring duties until they enter the domestic market. Benefits include:

• Storage and manipulation without customs formalities.
• Duties are only paid when goods enter the importing country's territory.
• Savings on unassembled goods and protection against theft.

Cost Characteristics of Transport Modes

• Rail: High fixed costs, low variable costs. Efficient for long distances and high volumes.
• Road: Lowest fixed costs but high variable costs (fuel, labor, maintenance).
• Water: High terminal costs but very low line-haul costs. Significant economies of scale.
• Air: High variable costs influenced by distance; premium service for short lead times.
• Pipeline: Highest ratio of fixed costs to total costs. Requires high volume.

Rate Structures and Pricing

Common rate structures are related to volume, distance, and demand:

• Tapering Rates: Rates increase with distance but at a decreasing rate.
• Blanket Rates: Single rates covering a wide geographic area.
• Class Rates: Linked to product classification (density, stowability, liability).
• Contract Rates: Negotiated rates for specific shippers or volumes.

Documentation and Legal Responsibilities

• Bill of Lading: A legal contract, receipt for goods, and evidence of title.
• Straight Bill of Lading: Non-negotiable.
• Order Bill of Lading: Negotiable; can be traded or sold.
• Freight Bill: An invoice for the transportation charges.

Rail Transport Technology

Rail is a catalyst for economic growth, especially for heavy commodities. Modernization efforts include:

• Conversion to roller bearings and air braking.
• Stainless steel wagon bodies for durability.
• RFID and GPS tracking for rolling stock.
• Road-Railer Concept: Using car racks on standard container wagons for the auto industry.

Storage and Materials Handling Systems

Storage is often called 'transportation at zero miles per hour.' It coordinates supply and demand and assists in production (e.g., aging wine or cheese).

Storage Functions

• Holding: Protection and orderly storage.
• Consolidation: Combining small shipments to reduce costs.
• Break-Bulk: Dividing large shipments for local distribution.
• Cross-Docking: Direct transfer from inbound to outbound with minimal storage.

Materials Handling

• Unitization: Using pallets and containers to increase efficiency.
• Space Layout: Balancing handling costs with space utilization.
• CPO Index: Cube-per-order index used to locate high-turnover items near docks.

Environmental Impact of Transport

Transport contributes to local and global pollution, noise, accidents, and congestion. Optimal fuel efficiency is typically achieved at 70–80 km/h; consumption rises sharply below 40 km/h.

Quantifying Environmental Costs

Impact assessments focus on human health, building materials, and crops, translating these into monetary costs via market prices or 'willingness to pay' models.

Incoterms and Maritime Zones

Incoterms provide consistency in international trade, defining which party pays for transport, taxes, and insurance. It is essential to clarify which version (2000 vs. 2010) is being used.

Fresh Logistics: Perishable Supply Chains

Perishables include fresh food, plants, and frozen products. They require strict temperature control (-0.5°C to 15°C) and ventilation.

Reefer Containers

• Porthole Containers: Insulated boxes cooled by a ship's central plant.
• Integral Containers: Self-contained units with built-in refrigeration powered by electricity or diesel generators.

Inventory Functionality and Management

Inventory serves four main functions: geographical specialization, decoupling, supply/demand balancing, and buffering uncertainty (safety stock).

Inventory Carrying Costs

• Capital: Interest on money tied up in stock.
• Taxes and Insurance: Based on value and risk.
• Obsolescence: Costs from product deterioration.
• Storage: Facility expenses.

Management Policies

• Pull Approach: Driven by customer demand (e.g., Quick Response, VMI).
• Push Approach: Based on forecasted demand (e.g., DRP, MRP).
• ABC Classification: Using Pareto 80/20 analysis to prioritize high-value items.

Green Logistics and Sustainability

Sustainability broadens performance to include social, environmental, and economic factors (The Triple Bottom Line). Initiatives include mode shifting, improved equipment, and optimized routing to reduce 'extra distance' and carbon emissions.

Reverse Logistics and Waste Management

Reverse logistics manages the upstream flow of goods, information, and money. It includes product recalls, returns, and waste management.

Waste Categories

• Hazardous: Negative impact on health/environment (e.g., toxic waste).
• Non-Hazardous: Domestic or light industrial waste.

Life-Cycle Assessment (LCA)

A 'cradle-to-grave' perspective evaluating the environmental burden of a product throughout its entire life cycle, from design and sourcing to distribution and recycling.

ISO 14000

An international standard for environmental management systems, helping firms monitor compliance and commit to specified performance levels.
