THE DESIGN AND ANALYSIS OF EXPERIMENTS. By Oscar Kempthorne. New York, John Wiley and Sons, Inc., 1952. 631 pp. $8.50. This book by a teacher of statistics (as well as a consultant for \"experimenters\") is a comprehensive study of the philosophical background for the statistical design of experiment. It is necessary to have some facility with algebraic notation and manipulation to be able to use the volume intelligently. The problems are presented from the theoretical point of view, without such practical examples as would be helpful for those not acquainted with mathematics. The mathematical justification for the techniques is given. As a somewhat advanced treatment of the design and analysis of experiments, this volume will be interesting and helpful for many who approach statistics theoretically as well as practically. With emphasis on the \"why,\" and with description given broadly, the author relates the subject matter to the general theory of statistics and to the general problem of experimental inference.

A review of dynamic vehicle routing problems

Location-based services (LBS) use positioning technologies to provide individual users with reachability and accessibility that would otherwise not be available in the conventional commercial realm While LBS confer greater connectivity and personalization on consumers, they also threaten users' information privacy through granular tracking of their preferences, behaviors, and identity To address privacy concerns in the LBS context, this study extends the privacy calculus model to explore the role of information delivery mechanisms (pull and push) in the efficacy of three privacy intervention approaches (compensation, industry self-regulation, and government regulation) in influencing individual privacy decision making The research model was tested using data gathered from 528 respondents through a quasi-experimental survey method Structural equations modeling using partial least squares validated the instrument and the proposed model Results suggest that the effects of the three privacy intervention approaches on an individual's privacy calculus vary based on the type of information delivery mechanism (pull and push) Results suggest that providing financial compensation for push-based LBS is more important than it is for pull-based LBS Moreover, this study shows that privacy advocates and government legislators should not treat all types of LBS as undifferentiated but could instead specifically target certain types of services

The Role of Push-Pull Technology in Privacy Calculus: The Case of Location-Based Services

Purpose – The purpose of this paper is to review the growing literature examining supply chain risk management (SCRM) and to develop a typology of risks in the supply chain.Design/methodology/approach – The paper draws its insights and conclusions from a review of the literature on supply chain risk, and a synthesis of the broader domain of risk management.Findings – While the literature on SCRM is growing, the literature lacks an organized structure for the sources of supply chain risk. The current paper bridges this gap by synthesizing the diverse literature into a typology of risk sources, consisting of environmental factors, industry factors, organizational factors, problem‐specific factors, and decision‐maker related factors.Practical implications – The paper devises a typology that can be used by managers to measure and assess the vulnerabilities of their company and supply chain. The typology also provides avenues for future research that further guides practitioners in the management of their supp...

Supply chain risks: a review and typology

Since the late 70s, much research activity has taken place on the class of dynamic vehicle routing problems DVRP, with the time period after year 2000 witnessing a real explosion in related papers. Our paper sheds more light into work in this area over more than 3 decades by developing a taxonomy of DVRP papers according to 11 criteria. These are 1 type of problem, 2 logistical context, 3 transportation mode, 4 objective function, 5 fleet size, 6 time constraints, 7 vehicle capacity constraints, 8 the ability to reject customers, 9 the nature of the dynamic element, 10 the nature of the stochasticity if any, and 11 the solution method. We comment on technological vis-i-vis methodological advances for this class of problems and suggest directions for further research. The latter include alternative objective functions, vehicle speed as decision variable, more explicit linkages of methodology to technological advances and analysis of worst case or average case performance of heuristics. © 2015 Wiley Periodicals, Inc.

Dynamic vehicle routing problems: Three decades and counting

Wireless positioning determination has received increased attention during the past few years. Several wireless applications have been envisaged when mobile terminal location can be determined with sufficient accuracy at any time. In this paper, we attempt to identify the various indoor and outdoor positioning techniques that can be used for the provision of mobile and wireless applications and services. In order to maximize the benefits of this research in the area of positioning technologies, we propose a novel taxonomy with detailed analysis and evaluation of these techniques based on the accuracy that is needed for various mobile location-based services.

Vehicle routing (VR) is critical in successful logistics execution The emergence of technologies and information systems allowing for seamless mobile and wireless connectivity between delivery vehicles and distribution facilities is paving the way for innovative approaches to real‐time VR and distribution management This paper investigates avenues for building upon recent trends in VR‐related research towards an integrated approach to real‐time distribution management A review of the advances to‐date in both fields, ie the relevant research in the VR problem and the advances in mobile technologies, forms the basis of this investigation Further to setting requirements, we propose a system architecture for urban distribution and real‐time event‐driven vehicle management

– The paper examines the circumstances of success in telematic use and strategic effects resulting from the implementation and use of such technologies from SMEs in the Greek Market., – The analysis is based on a three‐phased triangulated research methodology; that is literature review, interviews from 15 logistics directors and a questionnaire survey of 73 logistics SMEs in Greece., – The basic finding that has been derived from both phases 2 and 3 (survey and interviews) is that although the penetration of telematics is still low in Greece, logistics operators understand the importance of mobile services and they already know which they plan to their customers., – An inherent limitation of this survey is the fact that it address, like all surveys, the requirements of its respondents only, without taking into account., – This paper explores customer perceptions and requirements for the implementation of mobile real‐time support services for city logistics. The requirements, elicited by the results of the survey, are used to propose a systemic representation of a real‐time vehicle management mechanism for urban transportation.
