6. Dimensions of Logistics: Introduction
Logistics has come a long way since the 1960s.
The big challenge is to manage the whole logistics system in such a way that order fulfillment meets or exceeds customer expectations.
Focus of this chapter is upon the individual firm’s logistics system but also recognizing that no logistics system operates in a vacuum.

9. Logistics in the Economy: A Macro Perspective
As indicated in Figure 2-2, logistics costs as a percentage of GDP have declined from 16 percent in 1980, to under 10 percent in 1999.
Early to mid-1970s saw the figure closer to 20 percent.
This reflects a serious improvement in the efficiency of logistics systems.
Figure 2-3 shows a further breakdown of logistics costs for 1999.

12. Logistics in the Economy: A Macro Perspective
As indicated in Figure 2-4, the Federal Reserve measure of inventory to sales ratios from 1991 to 1999 clearly indicate that companies are getting better at managing inventory.
Companies have been supporting larger amounts of sales with decreasing amounts of inventory.
Chapter 2
Management of Business Logistics, 7th Ed.

13. Logistics in the Economy: A Macro Perspective
The two largest cost categories in logistics systems are transportation and inventory.
While we will look at this in Chapter 9, motor carriers’ share of total freight expenditures is $450 billion versus $99 billion for all other carriers.
The most frequent trade-off in logistics is between transportation and inventory cost.

17. What is Logistics?: 21st Century View of Logistics
Business Logistics – supply chain process that plans, implements, and controls the efficient, effective flow of goods, services, and related information from the point of origin to the point of use or consumption in order to meet customer requirements.
Military Logistics – design and integration of all aspects of support for the operational capacity of the military forces, and their equipment to ensure readiness, reliability, and efficiency.
Chapter 2
Management of Business Logistics, 7th Ed.

18. What is Logistics?: 21st Century View of Logistics
Event Logistics – network of activities, facilities, and personnel required to organize, schedule, and deploy the resources for an event to take place and to efficiently withdraw after the event.
Service Logistics – acquisition, scheduling, and management of the facilities/assets, personnel, and materials to support and sustain a service operation or business.
Chapter 2
Management of Business Logistics, 7th Ed.

19. What is Logistics?: Value-Added Role of Logistics
Most commonly referred to in terms of economic utilities:
Form utility (what)
Place utility (where)
Time utility (when)
Possession utility (why)
Also referred to as the seven Rs --- Right product, Right quantity, Right condition, Right place, Right time, Right customer, and Right cost.

Logistics in the Firm: Logistics Interfaces with Operations Manufacturing
Length of production runs
Balance economies of long production runs against increased costs of high inventories.
Seasonal demand
Acceptance of seasonal inventory to balance lead production times.

23. Management of Business Logistics, 7th Ed.
Logistics in the Firm: Logistics Interfaces with Operations/Manufacturing
Supply-side interfaces
Stocking adequate supplies to ensure uninterrupted production now a logistics function.
Protective packaging
Principal purpose is to protect the product from damage.
Foreign & third party alternatives
Some logistics functions are being outsourced.

Logistics Interfaces with Marketing: The Marketing Mix – Four Ps
Price
Product
Promotion
Place
Chapter 2
Management of Business Logistics, 7th Ed.

25. Logistics in the Firm: Price
Carrier pricing
Generally, since the larger the shipment, the cheaper the transportation rate, shipment sizes should be tailored to the carrier’s vehicle capacity where possible.
Matching schedules
Quantity discounts should be tied to carrier quantity discounts.
Volume relationships
Volumes sold will affect inventory requirements.
Chapter 2
Management of Business Logistics, 7th Ed.

26. Logistics in the Firm: Product
Consumer packaging
Generally, since the size, shape, weight and other physical characteristics of the product impact on its storage, transportation and handling, the logistics managers should be included in any decisions regarding these product traits.
A minor correction in any of the above could conceivably cost (or save) millions of dollars in logistical costs.
Logistics costs are not necessarily paramount, but they need to be considered in the decision making process.
Chapter 2
Management of Business Logistics, 7th Ed.

27. Logistics in the Firm: Promotion
Push versus pull
The most important factor is that the logistics division is aware of any changes in demand patterns so that it can plan for any consequences.
Pull strategies tend to be more erratic.
Push strategies tend to more predictable.
Channel competition
The more popular a product, the easier it is to persuade channel members to promote your product.
Chapter 2
Management of Business Logistics, 7th Ed.

28. Logistics in the Firm: Place
Wholesalers
Generally, since wholesalers are combining purchases for multiple retailers, the shipment sizes tend to be larger and the number of transactions that have to be processed are fewer, with the result that logistics costs are smaller.
Retailers
With the exception of very large retailers who act more like wholesalers, smaller sales are the norm. These generally cost more for transportation and order processing.
Chapter 2
Management of Business Logistics, 7th Ed.

29. Logistics Interfaces with Other Areas
Manufacturing and marketing are probably the two most important internal, functional interfaces with logistics.
Other important interfaces now include finance and accounting.
Logistics can have a major impact on return on assets and return on investment.
Logistics costs reported by cost systems measure supply chain trade-offs and performance.

31. On the Line: Toyota Distribution
Moves more than 8 million parts and accessories every month.
Computer modeling re-designed the 30 year old distribution network.
Software looked first at Lexus Division and then at the entire network.
Resulted in two DCs, one in California, another in Kentucky, feeding nine smaller DCs located around the country.
The new network both improved customer service and lowered costs.

32. Management of Business Logistics, 7th Ed.
Approaches to Analyzing Logistics Systems: Materials Management v. Physical Distribution
Frequently the movement and storage of raw materials is far different from the movement and storage of finished goods.
Four different classifications of logistics systems
Balanced system - e.g., consumer products
Heavy inbound - e.g., aircraft, construction
Heavy outbound - e.g., chemicals
Reverse systems - e.g., returnable products
Chapter 2
Management of Business Logistics, 7th Ed.

33. Approaches to Analyzing Logistics Systems
Cost Centers
Treating logistics activities as cost centers makes it easier to study cost trade-offs between the centers. (see Tables 2-2 and 2-3)
Nodes versus Links
Nodes are spatial points (warehouses, plants, etc.);
Links are the transportation network (rail, motor, air, pipe and water). (see Figure 2-6)
Logistics Channel
The network of intermediaries involved in the logistics system. (see Figures 2-7, 2-8, and 2-9)

40. Logistics and Systems Analysis
Cost Perspective
Keep in mind that the most efficient systems are not always comprised of each system component operating at its lowest possible cost.
The critical concern is to have the entire system operating at its lowest total cost.
Chapter 2
Management of Business Logistics, 7th Ed.

41. Logistics and Systems Analysis
Level of Optimality
There are often constraints working which result in sub-optimal outcomes.
Additionally, logistics systems must work in harmony with marketing, finance, production, etc.--- this may also result in sub-optimal logistics performance.
See Figure 2-10 on next slide.

43. Techniques of Logistics System Analysis: Short-Run/Static Analysis
This technique is illustrated in Table 2-4.
Comprised a matrix-like table which presents each of the logistics and other relevant costs for two or more alternative logistics systems.
The major downside to the model is that it presents a solution which is not necessarily the correct one at all possible volume levels.
Examine the data presented in Table 2-4.

45. Techniques of Logistics System Analysis: Long-Run/Dynamic Analysis
This technique is illustrated in Figure 2-11.
Comprised a graph of the fixed and variable costs of at least two alternative logistics systems.
The graph may have at least one indifference point, but may have multiple points of indifference.
