What is Logistics • What is Logistics • Logistics is the process that integrates and coordinates the elements within the supply chain to ensure that best possible flow of materials and information, in order to meet customer requirements in the most efficient manner and at the lowest possible cost.
What is Logistics • Definition: • The art of science and management, engineering, and technical activities concerned with requirements, design, and supplying and maintaining resources to support objectives, plans, and operations.1 • The branch of military science having to do with procuring, maintaining, and transporting material, personnel, and facilities.2
What is Logistics • Definition: • Logistics is the process of planning, implementing and controlling the efficient, cost effective flow and storage of raw materials in-process inventory, finished goods and related information from point of origin to point of consumption for the purpose of conforming to customer requirements.3
What is Logistics • Definition: • Logistics is a support element of the organ-ization that incorporates elements such as: Transportation Storage Spare & Repair Parts Facilities Personnel and Training Technical Publications Test and Support Equipment • “The process of having the right quantity of the right item in the right place at the right time.4

What is Logistics • Evolution of Logistics (Prior to 1950)5: • Prior to the 1950’s, the typical enterprise treated the process of logistical management on a fragmentary basis. • Concerns were place on: 1. Line-item proliferation 2. Selling identical products through a wide variety of marketing channels 3. Widespread offering of product- contained services
What is Logistics • Evolution of Logistics (Prior to 1950)5: • Two reasons why logistics was neglected and subsequently late in development were: 1. Computers were not a commonplace and quantitative analysis was rarely used 2. The volatile economic climate and profit margins were not typically scrutinized
What is Logistics • Evolution of Logistics (1956 to 1965)5: • During the period of 1956 to 1965, four major concepts began to materialize: 1. Development of total cost analysis 2. Application of the system approach 3. Increased concern for customer service 4. Revised attention to marketing channels
What is Logistics • Evolution of Logistics (1966 to 1970)5: • A time which basic logistics were tested. • For the most part, logistical concepts passed the test of time. • Managerial emphasis focused on improved operating performances. • Firms placed a great deal of attention on finished-goods inventory management and support of customer orders.
What is Logistics • Evolution of Logistics (1966 to 1970)5: • Material management began to develop as an attempt to integrate the planning and logistical dimensions of purchasing and manufacturing. • Some draw backs: 1. Traffic mangers had a difficult time embracing that the overall total cost might be reduced by spending more on a specific activity such as transportation
What is Logistics • Evolution of Logistics (1966 to 1970)5: • Some draw backs (continue): 2. Widespread adoption of either physical distribution or materials management was the difficulty in presenting a case to support the hard-core return on investment that would materialize from implementation 3. Given the accounting practice of the times, it was difficult to place a monetary return or value on superior customer service performance
What is Logistics • Evolution of Logistics (1971 to 1979)5: • Energy shortages arose causing companies to place more emphasis on logistics. 1. Transportation 2. Inventory • Overnight, enterprise priorities shifted from servicing demand to maintaining supply. • Material management matured from the hazards of potential supply discontinuity. • Just-in-time was adopted. • Long term contra
What is Logistics • Evolution of Logistics (1971 to 1979)5: • Long term contracts were introduced. • Attention began to be directed to third-party logistical arrangements as an alternative solution to the growing complexity of logistical support. • The institutionalization of logistics within the organizational structures of countless private and public enterprises.
What is Logistics • Evolution of Logistics (1980 to 1985)5: • The early years of the 1980s experienced more change in logistical operations than was the case in any previous time period.6 • The most significant changes were: 1. Transportation Deregulation 2. Microprocessor Technology 3. Communication Revolution
What is Logistics • Evolution of Logistics (1986 and beyond)5: • The attainment of strategic goals rests with the development and implementation of a single overall logic. Integrated logistical management provides such a logic and is becoming increasingly relevant for at least five reasons.7 1. A great deal of interdependence between all logistical areas which can be exploited to the advantage of the enterprise
What is Logistics • Evolution of Logistics (1986 and beyond)5: 2. A narrower or restricted approach creates the potential for a dysfunctional interface 3. The control requirements for each operation are similar 4. An increasing awareness that many trade- offs exist between manufacturing economies and marketing requirements that can be reconciled by a wall-designed logistical system
What is Logistics • Evolution of Logistics (1986 and beyond)5: 5. The final and perhaps most significant reason for integrated logistics is that the complexity of contemporary logistics require innovative solutions
What is Logistics • Mission: • The mission of logistics Is to get the right goods or services to the right place, at the right time, and in the desired condition, while making the greatest contribution to the firm.
What is Logistics • From Cradle to Grave9 Market Volume Time Tech Obsolescence Tech Dev App Launch App Growth Mature Tech
What is Logistics • 3PL’s • Third party logistics are companies that specialize in logistics. • Firms hire them out for their knowledge and expertise. • Allows firms to concentrate on their core competence. • Complete confidence and trust must take place between both the 3PL and the firm hiring the 3PL.
What is Logistics • 3PL’s • Examples of 3PL’s 1. EDS 2. i2 Technologies 3. KPMG 4. Manugistics, Inc 5. Ryder Logistics 6. UPS Logistics
Why Logistics • Cutting Cost • Viewing the Life Cycle Cost • Logistics Management and the Balance Sheet • Technology Infusion Dilemma
Why Logistics • Cutting Cost • Chrysler Corp.’s Drive to Cut Costs10 Saved $2.1 billion this year as part of a drive to cut supply costs, a $900 million increase over last year “We’re constantly working with our suppliers as teammates to discover new ways to be more efficient” Suppliers submit proposals aimed at reducing logistics and manufacturing costs
Why Logistics • Cutting Cost • Forward thinking retailers, e.g., Wal-Mart, are using technology and optimizing transportation to better serve customers and squeeze cost out of the supply chain11 • Dell uses UPS to design a network of distribution models to help improve the time in transit of their products and reduce overall inventory
