buying materials to support the manufacturing process Manufacturing - making the product Fulfillment - managing the activities involved in delivering the product, i.e., moving and storing Copyright (c) 2004 Accenture All rights reserved You may only use and print one copy of this document for private study in connection with your personal, non-commercial use of a Supply Chain Academy course validly ...Reproduced with permission of the copyright owner.

I consider two practical motivations: vaccine for seasonal influenza (flu) epidemic and high-fashion luxury goods. In Chapter 2, I study the impact of yield uncertainty (supply side) and self-interested consumers (demand side) on the inefficiency in the influenza vaccine supply chain. Previous economic studies, focusing on demand side, find that the equilibrium demand is always less than the socially optimal demand since self-interested individuals do not internalize the social benefit of protecting others via reduced infectiousness (positive externality). In contrast, I show that the equilibrium demand can be greater than the socially optimal demand after accounting for the limited supply due to yield uncertainty and manufacturer’s incentives. The main driver for this result is a second (negative) externality: self- interested individuals ignore that vaccinating people with high infection costs is more beneficial for the society when supply is limited. I show that the extent of the negative externality can be reduced through more efficient and less uncertain allocation mechanisms. In order to investigate the relative effectiveness of government interventions on supply and demand sides under various demand and supply 4 characteristics, I construct two partially centralized scenarios, where the social planner (government) intervenes either on the demand side or the supply side but not both, and conduct an extensive numerical analysis. In Chapter 3, I develop a mechanism which coordinates a supply chain with consumption exter- nalities and a profit-maximizing manufacturer having uncertain production process in the presence of rational consumers. This mechanism includes tax/subsidy payments on the demand side (individual con- sumers) and a transfer payment on the supply side (manufacturer). I show that, under the mechanism, the manufacturer is ex ante better off; moreover, expected total utility of all individuals are higher. I also show that the mechanism allows arbitrary division of ex ante total social welfare between individuals and the manufacturer. Chapter 4 develops an analytical model to study the impact of snobbish (exclusivity-seeking) con- sumer behavior on a firm’s price and quantity decisions. I consider a profit-maximizing monopoly firm selling a product over two periods to two segments of consumers (with high and low valuation of the product), who are forward-looking and snobbish, i.e., their valuation of the product decreases as more people in the population consume it. This modeling framework enables me to explain the heterogeneity in pricing ANALYSIS OF THE SUPPLY CHAIN DESIGN AND PLANNING ISSUES: MODELS AND ALGORITHMS HUANG YIKAI (B.E. and M.

The goal of production planning is to support the manufacturing process by determining the resources and sequence of operations required to build a product During the production planning process, a company generates the detailed production schedule required to build a product The production schedule must be tightly linked with a detailed materials plan to ensure the raw materials are available when needed The planning process also communicates required materials to the purchasing department The primary business issues addressed by production planning include: • • Ensuring machines and materials are available for production when needed Maximizing throughput and utilization of factory resources Copyright (c) 2004 Accenture All rights reserved You may only use and print one copy of this document for private study in connection with your personal, non-commercial use of a Supply Chain Academy course validly licensed from Accenture This document, may not be photocopied, distributed, or otherwise duplicated, repackaged or modified in any way Note: interactive elements such as activities, quizzes and assessment tests are not available in printed form How is a Production Planning Integrated with Supply Chain Planning? Production planning is one component of the supply chain planning process Supply chain planning is an integrated process that allows companies to plan and integrate the supply chain functions of procurement, manufacturing, and fulfillment Demand, supply, production, and fulfillment planning operate as interdependent supply chain planning functions The goal is to integrate these processes so that all the plans are synchronized with one another Plans generated during one process are used by one or more of the other processes In other words, planners need to know: • • What to with the information generated How the different processes relate to one another Specifically, a materials planner may wonder, "What if my suppliers can't deliver to our requested quantities and timing?" There are many ways to resolve this issue One viable option is to delay the production of some of the items until materials are available, and inform fulfillment planning about the delay in meeting customer requirements Another option may be to work with Procurement to determine if the finished goods could be sourced from another vendor Copyright (c) 2004 Accenture All rights reserved You may only use and print one copy of this document for private study in connection with your personal, non-commercial use of a Supply Chain Academy course validly licensed from Accenture This document, may not be photocopied, distributed, or otherwise duplicated, repackaged or modified in any way Note: interactive elements such as activities, quizzes and assessment tests are not available in printed form Objectives After completing this module, you should be able to: • Discuss the purpose, objectives, and benefits of production planning • Describe the different components of production planning, the business problems it solves, and the key capabilities production planning offers • Identify key inputs, constraints, and other considerations for the components of production planning • Describe the measurements and metrics for production planning Copyright (c) 2004 Accenture All rights reserved You may only use and print one copy of this document for private study in connection with your personal, non-commercial use of a Supply Chain Academy course validly licensed from Accenture This document, may not be photocopied, distributed, or otherwise duplicated, repackaged or modified in any way Note: interactive elements such as activities, quizzes and assessment tests are not available in printed form Introduction to Production Planning Overview Once a company has developed demand and supply plans, it must plan how to manufacture the product Production planning (sometimes referred to ... Supply Chain Planning Functional Areas Supply chain planning allows companies to manage their supply chains by connecting the functions in the supply chain via a set of plans and processes Companies... available in printed form Supply Chain Planning Model Overview A supply chain planning (SCP) model is comprised of process, technology, and organizational assets Companies use these assets to intelligently... to meet the market demand for a product over time, and in the most profitable manner possible Supply chain planning allows companies to plan and integrate their supply chain functions at the execution,
