Reconciliation of temporal semantic heterogeneity in evolving information systems
(Massachusetts Institute of Technology. Engineering Systems Division, 2009-04)The change in meaning of data over time poses significant challenges for the use of that data. These challenges exist in the use of an individual data source and are further compounded with the integration of multiple ... -
Research Initiative to Understand & Model State Stability: Exploiting System Dynamics
(Massachusetts Institute of Technology. Engineering Systems Division, 2005-02)In its Preface, The 9/11 Commission Report states: “We learned that the institutions charted with protecting …national security did not understand how grave this threat can be, and did not adjust their policies, plans, and ... -
Residential satisfaction close to highways: The impact of accessibility, nuisances and highway adjustment projects
(Massachusetts Institute of Technology. Engineering Systems Division, 2013-01)In this paper we focus on gaining insight into the residential satisfaction of households near highways, based on survey data collected among 1,225 respondents in the Netherlands living within 1,000 meters from a highway. ... -
Reutilization and Legal Protection of Non-Copyrightable Database Contents
(Massachusetts Institute of Technology. Engineering Systems Division, 2006-08)The availability of data on the web and the improvement of technologies have made it increasingly easy to reuse existing data to create new databases and provide value-added services. Meanwhile, initial database creators ... -
Revisiting R[subscript 0], the Basic Reproductive Number for Pandemic Influenza
(Massachusetts Institute of Technology. Engineering Systems Division, 2008-02)This paper focuses on a fundamental input parameter for most existing mathematical models of pandemic influenza, the ‘basic reproductive number R[subscript 0],’ defined to be the mean number of new influenza infections ... -
Revisiting the Question: Are Systems of Systems just (traditional) Systems or are they a new class of Systems?
(Massachusetts Institute of Technology. Engineering Systems Division, 2014-03)This paper revisits a question asked and debated widely over the past decade: are Systems of Systems (SoS) just traditional systems or are they a new class of systems? Many have argued that SoS are a new class of systems, ... -
The Role of Subproject Task-Specific Attributes in Managing Enterprise-Wide Projects
(Massachusetts Institute of Technology. Engineering Systems Division, 2014-03)Realizing that different types of projects require different styles of management is becoming part of the mainstream theory and practice in project management. This paper addresses the question of whether the same notion ... -
Role of Technology in Manufacturing Competitiveness
(Massachusetts Institute of Technology. Engineering Systems Division, 2003-07)A manufacturing revolution has emerged in the past 50 years that is as significant as the industrial revolution of the 19th century. From 1950 to 2000, the average productivity growth in manufacturing in the United States ... -
Screening for Real Options “In” an Engineering System: A Step Towards Flexible System Development; PART I: The Use of Design Matrices to Create an End-to-End Representation of a Complex Socio-Technical System
(Massachusetts Institute of Technology. Engineering Systems Division, 2006-05)The goal of this research is to develop an analytical framework for screening for real options “in” an engineering system. Real options is defined in the finance literature as the right, but not the obligation, to take an ... -
