Supply Chain Management Manage what? materials,information and financial flows a network consisting of suppliers,manufacturing,distributors,and customer within the enterprise and outside the firm's allied business partners How? efficiently integrate suppliers,manufactures,warehouses,and stores synchronizing the flow of marketplace products,services,and information. Objective produce and distribute at the right quantities,to the right locations,and at right time (3R) minimize system wide costs while satisfying service level requirements highly competitive,customer-enriching supply system to create unique,individualized sources of customer value

Supply Chain Management Manage what? • materials, information and financial flows • a network consisting of suppliers, manufacturing, distributors, and customer • within the enterprise and outside the firm’s allied business partners How? • efficiently integrate suppliers, manufactures, warehouses, and stores • synchronizing the flow of marketplace products, services, and information. Objective • produce and distribute at the right quantities, to the right locations, and at right time (3R) • minimize system wide costs while satisfying service level requirements • highly competitive, customer-enriching supply system • to create unique, individualized sources of customer value

Introduction The Definition of Supply Chain Management (SCM) Hau-Lee,the head of Stanford Supply Chain Forum (1999): SCM deal with the management of materials,information and financial flows in a network consisting of suppliers, manufacturing,distributors,and customer. Simchi-Levi et al.(1999,p1):SCM is a set of approaches utilized to efficiently integrate suppliers,manufactures, warehouses,and stores,so that merchandise is produced and distributed at the right quantities,to the right locations,and at right time,in order to minimize system wide costs while satisfying service level requirements

Introduction The Definition of Supply Chain Management (SCM) • Hau-Lee, the head of Stanford Supply Chain Forum (1999): SCM deal with the management of materials, information and financial flows in a network consisting of suppliers, manufacturing, distributors, and customer. • Simchi-Levi et al.(1999,p1): SCM is a set of approaches utilized to efficiently integrate suppliers, manufactures, warehouses, and stores, so that merchandise is produced and distributed at the right quantities, to the right locations, and at right time, in order to minimize system wide costs while satisfying service level requirements

Introduction SCM is a continuously evolving management philosophy Seeks to unify the collective productive competencies and resources of business functions found both within the enterprise and outside the firm's allied business partners located along intersecting supply channels into highly competitive,customer-enriching supply system Focused on developing innovative solutions and synchronizing the flow of marketplace products, services,and information to create unique, individualized sources of customer value

Introduction SCM is a continuously evolving management philosophy ; Seeks to unify the collective productive competencies and resources of business functions found both within the enterprise and outside the firm’s allied business partners located along intersecting supply channels into highly competitive, customer-enriching supply system Focused on developing innovative solutions and synchronizing the flow of marketplace products, services, and information to create unique, individualized sources of customer value

Management philosophy Information,service,materials,financial flow along intersecting supply channels 。 Integrate resource;synchronizing the flow Objective: Competitive supply system Customer value added supply system

Management philosophy • Information, service, materials, financial flow • along intersecting supply channels • Integrate resource; synchronizing the flow Objective: • Competitive supply system • Customer value added supply system

Introduction The Supply Chain as a Strategy Weapon 0 The design of supply chain reflects a firm's strategic positioning;(low cost /fast response) Supply chain trade off between cost and response time; Third party logistic (3PL)is becoming more common Less expensive to subcontract logistics than to do it in- house. Maintain core competency SCM make it possible to move product quickly and efficiently so as to gain an edge over their competitors; (Outsourcing) New technologies will trim costs from the supply chain without compromising service

Introduction The Supply Chain as a Strategy Weapon • The design of supply chain reflects a firm’s strategic positioning; (low cost /fast response) • Supply chain trade off between cost and response time; • Third party logistic (3PL) is becoming more common  Less expensive to subcontract logistics than to do it in￾house.  Maintain core competency • SCM make it possible to move product quickly and efficiently so as to gain an edge over their competitors; (Outsourcing) • New technologies will trim costs from the supply chain without compromising service

Transportation Problem The transportation problem is a mathematical model for optimally scheduling the flow of goods from production factories to distribution centers. The transportation problem can be viewed as prototype supply chain problem Example 6.1 The Pear Disk Corp.produces 8GB drives in three plants and supply four distribution centers.The production capacities for the three factories in the next month are 45,000,120,000,and 95,000.The amounts shipped to the four DCs.are 80,000, 78,000,47,000,and 55,000.The unit cost for shipping 1,000 units drives from each plant to each warehouse is given.The goal is to determine a pattern of shipping that minimize the total transportation costs
