2 Overview of logistics Logistics of business is big and important
The logistical value proposition The work of logistics Logistical operations Logistics integration objectives Logistical operating arrangements Flexible structure Supply chain synchronization

3 What is Logistics? Logistics is the design and administration of systems to control movement and geographical positioning of raw materials, work-in-process, and finished inventories at the lowest total cost. The process that links the supply chain participants into integrated operations

4 Logistics

5 Logistics has risen to a key position in the global economy
Postwar U.S. ( ) Global leader in distribution and logistics, as a direct result of World War II Rise of European Economic Community and Asia ( ) Both regions became major exporters and distributors e-Commerce (1998-Present) Global logistics capability almost everywhere

6 Logistics will continue its renaissance in the future
Information technologies will automate many of the traditionally manual logistical functions: Automated port and rail operations RFID tagging of materials Advanced technologies for warehousing and inventory operations Removal of trade barriers will continue to expand global trade and logistics

7 Future

8 Goal of logistics management
Cost To satisfy customer expectations for delivery of products (or services) while minimizing the total cost Managers must support the requirements for procurement, manufacturing and customer accommodation supply chain operations Service

9 Transportation has become the major logistics cost component in the USA
$ Billion 1980 Logistics Cost of $451 billion is 16.1% of GDP Transportation ($214B) is 47.5% of Logistics Cost 2007 Logistics Cost of $1398B is 10.1% of GDP Transportation ($857B) is 61.3% of Logistics Cost Source: “19th” Annual “State of Logistics Report” © Council of Supply Chain Management Professionals, 2008

10 Logistics costs trends from Table 2.1
Transportation Costs relative to the Total Cost of Logistics have gone up Because of fuel prices and movement of manufacturing to Asia Inventory Costs relative to the Total Cost of Logistics have gone down Adoption of JIT and Lean practices have reduced these Administrative Costs relative to the Total Cost of Logistics have stayed the same

11 Inventory Levels

12 Diminishing inventories
Inventories. Manufacturers’ and trade inventories, adjusted for seasonal variations but not for price changes, were estimated at an end-of-month level of $1,350.0 billion, down 1.1 percent (±0.1%) from May 2009 and down 9.8 percent (±0.4%) from June 2008. Inventories. Manufacturers’ and trade inventories, adjusted for seasonal variations but not for price changes, were estimated at an end-of-month level of $1,359.9 billion, up 0.3 percent (±0.1%) from May 2010 and up 0.2 percent (±0.4%)* from June 2009. Inventories. Manufacturers’ and trade inventories, adjusted for seasonal variations but not for price changes, were estimated at an end-of-month level of $1,489.5 billion, up 0.7 percent (±0.1%) from May 2008 and up 5.6 percent (±0.4%) from June 2007. Inventories. Manufacturers’ and trade inventories, adjusted for seasonal variations but not for price changes, were estimated at an end-of-month level of $1,518.5 billion, up 0.3 percent (±0.2%) from May 2011 and up 11.1 percent (±0.4%) from June 2010.

13 Logistics Pressures Logistics Systems
Product proliferation shorter product life cycles Competitive Pressures Increasing customer service requirements Pressures for improved financial performance & inventory reductions Logistics Systems Regulatory changes Change in players & roles in distribution channels Changing materials handling & transport technologies Pressures to develop supply chain vision and co-operations Increasing customer service requirements Need to redesign and improve efficiency of logistics systems

14 Logistical value proposition
Logistical value proposition consists of a commitment to key customer expectations and requirements at a minimum cost The two elements of this value proposition are Service and Cost Minimization Firms must make appropriate tradeoffs between service and cost for each of their key customers

15 Service benefits are created by logistical performance in 3 areas
Availability involves having inventory to consistently meet customer material or product requirements Operational performance deals with the time required to deliver a customer’s order Key metrics for this area involve delivery speed and consistency Service reliability involves the quality attributes of logistics Key to quality is accurate measurement of availability and operational performance over time

16 Basic logistical service may not fit all customers
Basic logistics service describes the level of service a firm provides all established customers However, some customers require unique or special value-added services Managers must realize that customers are different and that services provided must be matched to accommodate unique requirements and purchase potential

17 Cost minimization using the total cost logistics model
Traditional Cost Logistics Model Total Cost Logistics Model Focused on achieving the lowest possible cost for each individual function of logistics For example, Transport the material the cheapest way possible Expected lowest cost based on decisions that were cheapest for individual functions Ignored the impact of cost decisions across logistics functions Focused on achieving the lowest total cost across each function of logistics A cost decision in one function should consider impact to costs of all other logistics functions For example, Transporting material the cheapest way is slower than other choices. This requires an increase in storage cost to hold the material longer Would it still be a lower cost to use the cheapest mode of transport?

18 Different perspectives on cost minimization
Traditional Cost Logistics Model Total Cost Logistics Model Minimize order processing cost + Minimize inventory cost + Minimize transportation cost + Minimize warehousing, materials handling and packaging cost + Minimize facility cost __________________________ Lowest logistics cost Minimize (order processing + inventory + transportation + warehousing, materials handling and packaging + facility) cost _________________________ Lowest total logistics cost

19 Example of evaluating alternatives to find lowest total cost
Compare two alternative shipping carriers to move a shipment of electronic chips Value of shipment = $25,000.00 Faster shipping is generally more expensive than slower shipping Carrier 1 costs $250 to ship Carrier 2 costs $20 more but delivers 1 day faster Product in transit is a form of inventory Holding costs for shipment is 40% of value per year No other cost differences across remaining logistics functions 19

20 Example of evaluating alternatives to find lowest total cost
Traditional Cost Method Minimize transportation cost Compare 1st carrier at $250 vs. 2nd carrier at $270 Decision is to use 1st Carrier to save $20 Total Cost Method Minimize total of transportation and inventory cost Compare 1st carrier at $250 + $27.40 = $ vs. 2nd carrier at $270 Decision is to use 2nd Carrier since it is a lower total cost Daily cost of holding product = x /365 Annual holding cost Product value = (.40 x $25,000)/ 365 = $27.40

21 Table 1.2 Eight Supply Chain Processes
Integrative management requires simultaneous achievement of 8 processes Table 1.2 Eight Supply Chain Processes

22 Major Functional Areas of Logistics
Order Processing Inventory Transportation Warehousing, Materials Handling, and Packaging Integrated through a network of facilities E.g. warehouses and distribution centers

23 Integrated logistics framework
Goal is to achieve customer satisfaction at the lowest Total Cost Decisions in one functional area will impact cost of all others We integrate the logistical functions into a coherent framework starting with the customer (Order processing) and ending with the customer (Transportation and Delivery)

24 Five interrelated functions of logistical work
Figure 2.1 Integrated Logistics

25 Strategic Planning Overview
External Environment Economic Regulatory Technological Competitive Internal Factors Strengths Weaknesses Opportunities Threats Corporate Objectives & Strategy SWOT PEST Competitive Strategy Functional strategic plans marketing production finance logistics The handbook of Logistics & Distribution Management 4th Edition

26 Order processing Order processing is the transmission of customer requirements to the supply chain Accurate information is needed to achieve superior logistical performance Responsive supply chains require accurate and timely information about customer purchase behavior Fast information flow enables improved work balancing

27 Inventory Inventory requirements of a firm are directly linked to the facility network and the desired level of customer service Inventory strategy seeks to achieve the desired customer service with the minimum inventory commitment Inventory strategy is based on a combination of Core customer segmentation Product profitability Transportation integration Time-based performance Competitive performance

28 Transportation Transportation is the operational area that geographically moves and positions inventory There are three basic ways to satisfy transportation requirements Operate a private fleet of equipment Contract with dedicated transport specialists Engage carriers that provide different transportation services as needed on a per shipment basis

29 Warehousing, materials handling and packaging
These work activities are integral parts of other logistical functions Inventory typically needs to be warehoused at selected times during the logistics process Transportation vehicles require materials handling for efficient loading and unloading Individual products are most efficiently handled when packaged together into shipping cartons Effective integration of these functions facilitates the speed and overall ease of product flow throughout the logistical system

30 Facilities network The number, size and geographical relationship of facilities used to perform logistical operations directly impacts customer service capability and cost Types of facilities in the logistics network include Manufacturing plants, warehouses, cross-dock operations and retail stores

31 The scope of integrated logistical operations
Inventory Flow Information Flow Figure 2.2 Logistical Integration

32 Inventory flow Managers must be concerned with the movement and storage of inventory in 3 major forms Materials Work-in-process Finished products Logistical operations should add value by moving inventory when and where needed Materials and components gain value at each step of their transformation into finished inventory

33 3 areas of value-added logistic process
Customer accommodation is the movement of finished product to customers Manufacturing support concentrates on managing work-in-process inventory as it flows between stages of manufacturing Procurement is concerned with purchasing and arranging inbound movement of materials, parts, and/or finished inventory from suppliers into manufacturing or assembly plants, warehouses or retail stores

34 Information flow Information flow identifies specific locations within a logistical system that have requirements Information also integrates the three operating areas Information facilitates coordination of planning and control of day-to-day operations Logistical information has two major components Planning / coordination information Operational information needed to complete work

35 Logistical integration requires achieving six objectives simultaneously
Responsiveness Variance reduction Inventory reduction Shipment consolidation Quality Life cycle support

36 Logistical operating arrangements
All logistical arrangements share two common characteristics They are designed to manage inventory The range of logistics alternatives is limited by available technology Three widely utilized structures are Echelon (traditional) is a linear flow from origin to destination through buffers or warehouses/distribution centers Direct is designed to ship products directly to customer’s destination from one or a limited number of centrally located inventories Combined is a combination of Echelon and Direct, depending on the product, market, or customer

37 Echelon Structured Logistics

38 Combined Echelon and Direct Delivery

39 Flexible structures are programs to service customers using alternatives
Flexible operations are preplanned contingency strategies to prevent logistical failures For example, a warehouse is out of an item so a contingency policy assigns the total order to another warehouse The structure appears the same as a combined arrangement, but with the ability to change the logistical structure to suit the service need Different approaches for different situations Very common with “factory-less” companies like Nike and Best Buy

40 Example situations for flexible logistics structure
The customer-specified delivery facility might be near a point of equal logistics cost or equal delivery time from two different logistics facilities The size of a customer’s order creates improved logistical efficiency if serviced through an alternative channel arrangement Decision to use a selective inventory stocking strategy Agreements between firms to move selected shipments outside the established echeloned or direct arrangements

41 Flexible Echeloned and Direct Delivery

42 Supply chain synchronization
Supply chain synchronization is the operational integration of multiple firms across a supply chain Seeks to coordinate the flow of materials, products and information between supply chain partners to reduce duplication of effort Seeks to reengineer internal operations of individual firms to leverage overall supply chain capability

43 The logistics performance cycle
The performance cycle represents elements of work necessary to complete the logistics related to customer accommodation, manufacturing or procurement A performance cycle consists of the following elements Nodes Links Inventory Base stock Safety stock Input and output requirements

44 Logistical Performance Cycles
Input and output requirements are not illustrated

45 Performance cycle uncertainty
Major objective of logistics in all areas is to reduce performance cycle uncertainty Operational variance is randomly introduced during the cycle through The structure of the performance cycle itself Operating conditions The quality of logistical operations

46 Total time is based on each task within the cycle
Figure 2.8 Performance Cycle Uncertainty

47 Ways to improve performance cycle times
EDI (Electronic Data Interchange) or Internet order management and tracking RFID or Bar code material tracking Automated inventory management Automated order selection and picking Communication with customers to determine their needs Communication with suppliers to determine their capabilities Lean Concepts

48 Performance cycle synchronization
Delayed or faster performance at any point along the supply chain results in potential disruption of operations Once consistent operations are achieved, managers can focus on reducing the time to complete the performance cycle to a minimum
