the right place, at the right time
• The procurement, maintenance, distribution and replacement of personnel and materials –
Webster’s Dictionary
• The science of planning, organizing and
managing activities that provide goods or
services – Logistics World, 1997
Trang 5SDM – Ch 15 Tata McGraw Hill
Logistics

Logistics and Marketing
• Interface on:
– Product design and pricing
– Customer service policies
– Sales forecasts and order processing
– Inventory policies and location of warehouses
– Channels of distribution and despatch planning
– Transportation to reach products to customers
• Production wants larger production runs to
minimise time spent on set up changes on the machines Marketing wants smaller runs of a variety of products

Trang 14– Increasingly demanding, informed customer base
– Purchase decisions on dimensions of quality, price and time
• Innovative supply chain:
– To meet customer driven challenges
– To reduce costs
– Improve service levels
– Enhance speed to market
Trang 15SDM – Ch 15 Tata McGraw Hill
Supply Chain Integration

Trang 17SDM – Ch 15 Tata McGraw Hill
Why Carry Inventory?
• Support production requirements
• Support operational requirements
• Maximize customer service – ensure availability when needed – protect
against uncertainty
• Hedge against marketplace uncertainty
• Take advantage of order quantity
discounts
Trang 18SDM – Ch 15 Tata McGraw Hill
Functions of Inventory
• Inventory serves as a buffer between:
– Supply and demand
– Customer demand and finished goods
– Requirements for an operation and the output from the previous operation
– Parts and materials to begin an operation and the suppliers of the materials
The shock absorber of business !
Trang 19SDM – Ch 15 Tata McGraw Hill
Factors Which Drive Inventory
• Target service level parameters
• Lot sizing practices
• Safety stock and safety time
Trang 20SDM – Ch 15 Tata McGraw Hill
Categories of Inventory
• Anticipation – built in anticipation of future
demand – peak season, strike, promotion
• Fluctuation (safety) – to cover random,
unpredictable fluctuations in supply and
demand and lead time – to prevent disruption
in operations, deliveries etc
• Lot-size – to take advantage of quantity
discounts, reduce shipping, set up and
clerical costs – also called cycle stock
Trang 21SDM – Ch 15 Tata McGraw Hill
Categories of Inventory
• Transportation – pipeline or movement
inventories – to cover the time needed to move from one point to another – factory to distribution point for example
• Hedge – for materials where prices are
volatile
• Maintenance, repair and operating supplies (MRO) – to support M and O – spare parts, lubricants, consumables etc
Trang 23SDM – Ch 15 Tata McGraw Hill
Performance Measures
• Inventory turns = Annual cost of goods
sold /average inventory in value
• Days of sales = inventory on hand /
average daily sales
Trang 24SDM – Ch 15 Tata McGraw Hill
Types of Inventory Systems
• Pure Inventory – when and how much to
order RM procurement Simple
manufacturing operations
• Production Inventory – finite production
rates Demand fluctuation Products compete for manufacturing capacity
• Production – distribution Inventory –
compete for production capacity Geographic placement of inventory for best service of
demand
Trang 25SDM – Ch 15 Tata McGraw Hill
Types of Classification
• ABC category – most common for all
• HML - high, medium, low - similar
• FSND – fast moving, slow moving,
non-moving, dead – spare parts / FG
• SDE – scarce, difficult, easy to obtain –
Trang 26SDM – Ch 15 Tata McGraw Hill
ABC Inventory Analysis
• Based on Pareto’s law:
– A – 20% items worth 80% of value
– B – 30% items worth 15% of value
– C – about 50% items account for 5% of the usage
• Classify items based on the above criteria
• Apply degree of control in proportion to the importance of the group
Trang 27SDM – Ch 15 Tata McGraw Hill
Inventory Related Costs
• Unit costs – basic value of the item carried
• Ordering costs – generating and sending a material release, transport, any other
acquisition costs
• Carrying costs – capital, storage,
obsolescence
• Stock-out costs
• Quality costs – non-conforming goods
• Other costs – duties, tooling, exchange rate differences etc
Trang 28– Safety stocks and forecasting methods
– Excess and obsolete inventory
• Part simplification and re-design
• On-site supplier managed inventory
• Use of supply chain inventory management
systems, Materials Requirement Planning,
Distribution Requirement Planning etc
• Automated inventory tracking systems
• Supplier – buyer cycle-time reduction
Warehouse management…
Trang 29SDM – Ch 15 Tata McGraw Hill
Stores Management
Objectives
• Providing efficient service to users
• Reduce cost of carrying goods
• Providing correct, updated stock figures
Trang 30Temporary Permanent
Receive goods
Identify goods
Sort goods Despatch to storage
Trang 31SDM – Ch 15 Tata McGraw Hill
Purpose of Warehousing
• To provide desired level of customer
service at the lowest possible total cost
• It is that part of the firm’s logistics system that stores products (RM, Packing Materials, WIP, FG) at and between point of origin and point
of consumption and provides info to
management on the status, condition and
disposition of items being stored
• Distribution warehousing relates mainly to FG
Trang 32SDM – Ch 15 Tata McGraw Hill
Reasons for Warehousing
Maintain source of supply
Support customer service
Support JIT programs of
suppliers and customers
Provide customers with the right
mix of products at all times
Temporary storage of materials
to be disposed or re-cycled
Achieve production economies
Achieve transportation economies
Take advantage of Quantity Purchase discounts and forward buys
Least Logistics cost for a desired level of customer service
Trang 34SDM – Ch 15 Tata McGraw Hill
Distribution Warehousing
• The objective is to set up a network of
warehouses closest to the customer
locations to service markets better and minimise cost
• Could be C&FA s, depots or distribution centers
• Macro location strategies:
– Market positioned
– Production positioned
– Intermediately positioned
Trang 35SDM – Ch 15 Tata McGraw Hill
Distribution Center
• Warehouse designed to speed the flow
of goods and avoid unnecessary costs
• Speeds bulk-breaking to avoid
inventory carrying costs
• Helps to centralise control and
co-ordination of logistics activities
• Products can also be cross-docked
(one vehicle to another)
Market positioned
Trang 36• Factors influencing are:
– Order cycle time
Trang 37• Factors influencing are:
– Perishability of raw materials
– Number of products in the product mix
– Assortments ordered by customers
– Transport consolidation rates ex; FTL
In between…
Trang 38SDM – Ch 15 Tata McGraw Hill
Intermediate Positioned
• Mid point locations between the final
customer and the producer
• High customer service levels possible even if
products made in number of units
• Other macro approaches look at cost
minimisation or cost and demand elements to
maximise profitability
Transportation management….
Trang 39SDM – Ch 15 Tata McGraw Hill
Transportation
• Very important in the Logistics function:
– Movement across space or distance adds value to products
– Transportation provides time and place utility
• Role of transportation includes:
– Provides opportunity for growth under competitive conditions
– Deeper penetration into markets
– Can influence product prices favourably
Principles….
Trang 40SDM – Ch 15 Tata McGraw Hill
Transportation Principles
• Continuous flow
• Optimise unit of cargo - stackability
• Maximum vehicle unit – capacity utilization
• Adaptation of vehicle unit to volume and
nature of traffic
• Standardisation
• Compatibility of unit load equipment
• Minimum of dead weight to total weight
• Maximum utilization of capital, equipment and personnel
Process….
Trang 41SDM – Ch 15 Tata McGraw Hill
The Selection Criteria
• Environmental analysis: shipper, carrier, government regulations, public influence
• Deciding objectives
• Selecting mode
• Select transport type within the mode
• Define functions of transport
• Evaluation and control – customer
perception / satisfaction, best practice benchmarking
Trang 42SDM – Ch 15 Tata McGraw Hill
Cost Factors
• Can be product related or market related
• Product related: density, stowability, ease or difficulty of handling and liability
• Market related: competition, location of
markets, Government regulations, traffic in and out of the market, seasonality of
movements and impact on customer service
• Five prominent modes:
– Road, rail, air, water and pipeline
– Sixth one is use of Ropeways
Trang 43• Coverage – door-to-door for example
• Flexibility in handling a range of
products
• Loss and damage performance
• Additional services provided
Reverse logistics…
Trang 44SDM – Ch 15 Tata McGraw Hill
Reverse Logistics
• Movement of goods from the market or
customer back to the company
• The need:
– Increased awareness of the environment
– Stringent legislation
– For some it is part of the business
– Profitability of dealing with scrap, surplus
• Surplus, obsolescence can result due to:
– Over optimistic sales forecasts, change in product
specs, errors in estimating material usage, losses
in processing or overbuying based on incentives
Comparison of modes……
Trang 46• Not suitable for remote stations
• Costly terminal handling facilities
• Inflexible time schedules
Road transport…
Trang 47SDM – Ch 15 Tata McGraw Hill
Road Freight Advantages
• Through movement – direct from consignor to consignee, no transshipment
• Flexibility – routes and loading routines can
be easily altered, operate day and night
• Less capital costs – for own fleet + immunity from industrial action
• Fast turn-around – if articulated units like
tractors and trailers are used
• Minimum delays
Trang 48• Unsuitability for heavy loads – rail transport
more economical for bulk loads
• Unsuitability for long distances – again the rail telescopic rates are more favourable
Air transport….
Trang 49SDM – Ch 15 Tata McGraw Hill
Air Transport Advantages
• Faster mode
• Reduction in cost particularly inventory
• Broad service range
• Increasing capabilities
• Disadvantages:
– High cost
– Weather affects flight conditions
– Limitations on heavy consignments
Water transport……
Trang 50SDM – Ch 15 Tata McGraw Hill
Water Transport
• Advantages:
– Mass movement of bulk
– Lowest freight cost
– Preferred for long haul of low value commodities
• Disadvantages:
– Not for quick transit
– Suitable for certain types on commodities only
Pipeline….
Trang 51SDM – Ch 15 Tata McGraw Hill
Pipeline Movement
• Advantages:
– Reliable, continuous, all weather transport
– Low maintenance and operating costs
– Can traverse difficult terrain
– Minimal transit losses
– Operation round the clock, safe
– Economies of scale – double the throughput for only 30% additional cost
• Disadvantage is in the investment cost
Ropeways….
Trang 52SDM – Ch 15 Tata McGraw Hill
Ropeways
• Advantages:
– In hilly or inaccessible areas
– Long and circuitous routes with streams / deep
valleys
– For commodities capable of movement in ropeway
buckets
– Short haulages of less than 50 kms
– Areas where other carriers are uneconomical
• Disadvantages:
– Heavy investments
– Limitations on size and quantity of haul
