    Due to the fact that the double margin exists in the decentralized supply chain, many papers focus on the coordination of decentralized supply chain. In this paper, we classify these papers into three parts according to the structure of supply chain. The first kind of supply chain consists of one upstream supplier and one downstream retailer. The second one consists of multiple suppliers and a single retailer. The last one refers to the supply chain with multiple suppliers and a single retailer. This paper can enable readers to get the knowledge of existing research on supply chain coordination. We also give some interesting future research concerning this topic

    Examining price and service competition among retailers in a supply chain under potential demand disruption

    © 2017 Elsevier Ltd Supply chain disruptions management has attracted significant attention among researchers and practitioners. The paper aims to examine the effect of potential market demand disruptions on price and service level for competing retailers. To investigate the effect of potential demand disruptions, we consider both a centralized and a decentralized supply chain structure. To analyze the decentralized supply chain, the Manufacturing Stackelberg (MS) game theoretical approach was undertaken. The analytical results were tested using several numerical analyses. It was shown that price and service level investment decisions are significantly influenced by demand disruptions to retail markets. For example, decentralized decision makers tend to lower wholesale and retail prices under potential demand disruptions, whereas a proactive retailer needs to increase service level with an increased level of possible disruptions. This research may aid managers to analyze disruptions prone market and to make appropriate decision for price and service level. The manufacturer or the retailers will also be able to better determine when to close a market based on the proposed analysis by considering anticipated disruptions. The benefits and usefulness of the proposed approach are explained through a real-life case adopted from a toy supply chain in Bangladesh

    Social Services Viewed Through New Lenses: Agency Problems in Education and Health in Latin America

    Latin America spends large amounts of resources on social services, yet its life expectancy and education levels are low compared to other regions with similar levels of income. A key reason is the inherent difficulty of making social services produce efficiently in reponse to demands and needs. This article shows how improving the organization of these service systems can make a significant difference in health conditions and student learning. A general framework applying the lessons of theories of the firm to the particularities of social services is developed, followed by a summary of case studies which assessed the impact of organization on performance in education (in Brazil, Venezuela and Chile), and in health (in Uruguay, Chile and the Dominican Republic). The paper shows that the relationships and rules followed by governments, service providers, and consumers can mean the difference between success and failure. It also describes a wealth of approaches, some of them with long histories, that point toward better ways of organizing social services and ultimately improving health and education in the region. This document is the first chapter of the Research Network book entitled "La organizacion marca la diferencia: Educación y salud en América Latina. "

    Traditionally supply chain management has meant factories, assembly lines, warehouses, transportation vehicles, and time sheets. Modern supply chain management is a highly complex, multidimensional problem set with virtually endless number of variables for optimization. An Internet enabled supply chain may have just-in-time delivery, precise inventory visibility, and up-to-the-minute distribution-tracking capabilities. Technology advances have enabled supply chains to become strategic weapons that can help avoid disasters, lower costs, and make money. From internal enterprise processes to external business transactions with suppliers, transporters, channels and end-users marks the wide range of challenges researchers have to handle. The aim of this book is at revealing and illustrating this diversity in terms of scientific and theoretical fundamentals, prevailing concepts as well as current practical applications

    Comparison of institutional arrangements for river basin management in eight basins

    This study represents an effort toward understanding conditions that affect successful or unsuccessful efforts to devolve water resource management to the river basin level and secure active stakeholder involvement. A theoretical framework is used to identify potentially important variables related to the likelihood of success. Using a comparative case-study approach, the study examined river basins where organizations have been developed at the basin scale and where organizations perform management functions such as planning, allocation, and pricing of water supplies, flood prevention and response, and water quality monitoring and improvement. This paper compares the alternative approaches to basin governance and management adopted in the following river basins: the Alto-Tiete and Jaguaribe River Basins, Brazil; the Brantas River Basin, East Java, Indonesia; the Fraser River Basin, British Columbia, Canada; the Guadalquivir Basin, Spain; the Murray-Darling River Basin, Australia; the Tarcoles River Basin, Costa Rica; and the Warta River Basin, Poland. The analysis focuses on how management has been organized and pursued in each case in light of its specific geographical, historical, and organizational contexts and the evolution of institutional arrangements. The cases are also compared and assessed for their observed degrees of success in achieving improved stakeholder participation and integrated water resources management.Agricultural Knowledge&Information Systems,Water Supply and Sanitation Governance and Institutions,Town Water Supply and Sanitation,National Governance,Drought Management

    Out of sight, not out of mind: developments in economic models of groundwater management

    Get PDF
    Dynamic models of natural resource management have been applied to groundwater for decades, incorporating at least two inescapable aspects: first, since groundwater stocks are carried over to future periods, dynamic analysis is essential and any costs and benefits included in the analysis will require discounting; second, the positive and normative aspects of management must be clarified at the outset. The difference is fundamental even if the results of the two model types sometimes turn out to be fairly close. A whole strand of literature has been preoccupied with the question of whether policy interventions at least have the potential of improving groundwater management in a meaningful sense. However, given the well-documented parlous state of many aquifers around the world today, the focus has mostly shifted from debating whether or not intervention is worthwhile to identifying the relevant features of complex groundwater systems, designing better policies and facilitating their successful implementation. We survey developments in economic models relevant to groundwater management, focusing especially on the depiction of uncertainty and on the different methods applied to estimate the total economic value of groundwater.info:eu-repo/semantics/acceptedVersio
