Optimization Modeling for Logistics: Options and Implementations

Logistics optimization has significantly grown in popularity over the last few decades. Improvements in computing power, modeling software, and the willingness of companies to invest time in the modeling effort have allowed models that were once too unwieldy to solve to optimality to be solved quickly. This has led to a more wide‐spread recognition by logistics managers of the potential advantages of using optimization. The scope of logistics optimization in companies and organizations has expanded to address strategic, tactical, operational, and collaborative decision making. Spreadsheets, an analytical tool familiar to managers, have played a crucial role in the expanded modeling efforts of companies. Although optimization’s role in logistics has grown tremendously, there still are areas that remain to be explored that will allow it to achieve an even larger and more successful role in the management of companies. Additionally, there are some models that are still too large or too complex to currently solve to optimality, despite the advances in computing power and modeling/solving software.

More Than a Penny Saved: Long-Term Changes in Behavior Among Savings Program Participants

This article examines the levels of savings of former participants in a matched savings program. Findings from a survey of Individual Development Account (IDA) participants and a general low-income population sample show that participants who successfully completed the savings program report higher household savings than both participants who left the program early and a non-participant comparison group, suggesting that successful completion of an IDA program may improve the financial dispositions and behaviors associated with long-term savings. Three predictors of saving behavior emerged: access to the financial mainstream, individual psychological disposition, and the presence of children in the household.     

电子商务下的城市社区逆向物流柔性联合体平台

近年来,随着我国电子商务的不断发展以及社区功能的日益完备,逆向物流的规模和种类也不断增加,但目前电子商务环境下我国城市社区逆向物流发展还存在很多不足之处.为更好地解决电子商务环境下城市社区逆向物流环节中存在的问题,应借鉴供需网理念,建立一种包括逆向物流管理中心、逆向物流回收中心、逆向物流区域回收站、逆向物流社区回收点等多种角色的逆向物流柔性联合体协作模式,以弥补城市社区物流分散模式的弊端,提高效率,充分整合城市电子商务逆向物流相关企业的可用资源,降低社会总成本;应建立城市社区电子商务逆向物流联合体智能化信息平台,针对联合体中的四种主要角色,分别给出相应的信息平台,以满足不同层级信息处理与信息共享的需要.     

Competition In Mediation Services: Modeling the Role of Expertise,Satisfaction, and Switching Costs

This article analyzes competition among mediation service providers that match clients and vendors in a horizontally differentiated market. This is an issue that is important for decision support of mediators in determining pricing and service strategies. We present a simulation model to simultaneously represent search as well as the behaviors of clients, vendors, and multiple competing mediators. Among our findings: intermediaries find it optimal to offer registration fee incentives and derive revenues from transaction fees from successful matches; as switching costs increase, incumbent utilities increase and entrant utilities decrease; expertise, modeled as the ability of mediators to assess vendor attributes accurately, is a powerful competitive weapon for entrants to erode the incumbent intermediary's first mover advantage. On the other hand, client satisfaction is an instrument for an incumbent intermediary to deter entrance by competitors.

Negotiation for Cooperation in Logistics Networks: An Experimental Study

This paper investigates the negotiation problem in a supply chain in which a supplier can realize cost savings if she reaches an agreement with a retailer to use the retailers accurate market data for production planning. We study the participants behavior in an asymmetric and a symmetric information scenario and model the experimental study as a reverse ultimatum game. The main finding is that the revelation of information in the game leads to higher payoffs for both parties and to a higher welfare.     

Modeling e-loyalty: a moderated-mediation model

ABSTRACT

This work proposes a research model that elaborates upon the development of e-loyalty based on the signaling theory and attachment theory. In the model, e-loyalty is indirectly related to both visual appeal and an e-tailer’s service reputation through the full mediation of trust and affection. At the same time, the relationships between trust and e-loyalty and between affection and e-loyalty are hypothetically moderated by an e-tailer’s service reputation. The proposed hypotheses of this research were empirically tested using data from working professionals in high-tech firms in terms of online retailing. This study surveyed the same research participants at two different time points, one month apart, to verify the theoretical inferences. The empirical findings herein complement the previous literature by presenting how visual appeal and an e-tailer’s service reputation simultaneously influence e-loyalty through various mediating and moderating mechanisms.

Logistics Coordination in Dyads: Some Theoretical Foundations for EDI-Induced Redesign

Organizations are redesigning business processes in order to cope with changing organizational environments. Some of these redesigns are enabled by improved information technology. In this article, the redesign of logistics processes in dyadical partnerships is central. By focusing on the operational coordination between partners in the dyad, elements of a theory of logistics coordination are presented. A definition of coordination is given, the cause of coordination is assessed, and the factors that influence coordination are given. Uncertainty is identified as the core concept that causes and is simultaneously affected by coordination. Two process characteristics, "Degree of Freedom" and "Action Variety," are introduced to examine the potential of electronic data interchange (EDI) to redesign logistics coordination. EDI is perceived as a means that supports and intensifies coordination.
