Data And Analytics For Neighborhood Development: Smart Shrinkage Decision Modeling In Baltimore, Maryland, Michael P. Johnson Jr., Justin Hollander, Eliza D. Whiteman Jul 2015

Data And Analytics For Neighborhood Development: Smart Shrinkage Decision Modeling In Baltimore, Maryland, Michael P. Johnson Jr., Justin Hollander, Eliza D. Whiteman

Michael P. Johnson

Many older cities in the United States confront the problem of long-term decline in population and economic activity resulting in blighted conditions that make conventional revitalization initiatives unlikely to succeed. Smart shrinkage, a planning approach that emphasizes alternative land uses while preserving quality of life, offers a way for cities to remain desirable places to live and work. However, there is little research on empirical methods to support planning decisions consistent with smart shrinkage. We present results from two studies with planners from the City of Baltimore that provide novel insights regarding ways in which planners can perform vacant property …


Increased Awareness For Maritime Human Factors Through E-Learning In Crew-Centered Design, Gesa Praetorius, Aditi Kataria, Erik Styhr Petersen, Jens-Uwe Schröder-Hinrichs, Michael Baldauf, Nina Kähler Jun 2015

Increased Awareness For Maritime Human Factors Through E-Learning In Crew-Centered Design, Gesa Praetorius, Aditi Kataria, Erik Styhr Petersen, Jens-Uwe Schröder-Hinrichs, Michael Baldauf, Nina Kähler

Gesa Praetorius

In the past two decades, the need to address human factors in shipping through integration of ergonomics in the design of ships and shipboard equipment has increased significantly as a result of the technological development of modern ships. The International Maritime Organization (IMO), the United Nations’ specialized organizationfor ship safety issues, has adopted a vision to address human factors as a key element for the improvement of maritime safety, and in that context acknowledges the human element as complex and multi-dimensional. IMO’s standards focus on the avoidance of human and organization error. But in spite of this, and despite the …

Control And Resilience Within The Maritime Traffic Management Domain, Gesa Praetorius Nov 2014

Control And Resilience Within The Maritime Traffic Management Domain, Gesa Praetorius

Gesa Praetorius

This article presents research conducted within the Vessel Traffic Service (VTS) domain. VTS is a service that is provided close to ports and geographically challenging areas to support merchant vessels in their navigation. Although VTS is legally an advice and assistance service, applying concepts from Cognitive Systems Engineering and Resilience Engineering can highlight how the joint human-machine system works to promote safe and efficient traffic movements. The VTS is a Joint Cognitive System that maintains control through a mixture of opportunistic and tactical control. Strategic control is only partially supported by the higher levels of system aggregation that provide the …

Community Impacts Of Decision Modeling For Foreclosed Redevelopment, Michael P. Johnson Jr., Alvine Sangang, Buki Usidame Nov 2014

Community Impacts Of Decision Modeling For Foreclosed Redevelopment, Michael P. Johnson Jr., Alvine Sangang, Buki Usidame

Michael P. Johnson

Community development corporations purchase distressed housing to rehabilitate for renter or owner-occupancy. These mission-driven organizations, skilled in the business of housing development, often lack analytic expertise to determine which acquisitions to pursue that would maximize social impact. This paper presents results, using actual purchase data from a Boston-area CDC, to assess the potential social benefits associated with using a decision model as compared to conventional practices.

Data And Analytics For Neighborhood Development: Smart Shrinkage Decision Modeling In Baltimore, Maryland, Michael P. Johnson Jr., Justin Hollander, Eliza D. Whiteman

Michael P. Johnson

Many older cities in the United States confront the problem of long-term declines in population and economic activity in certain neighborhoods have resulted in blighted conditions that make conventional revitalization initiatives based on increased residential and commercial development unlikely to succeed. Planning scholars have developed a theory of smart shrinkage in which emphasis is placed on non-residential land uses that can maintain and improve quality of life while positioning some land for future growth-oriented activities (Hollander and Németh 2011). Smart shrinkage research and practice involves application of methods from information technology and decision science to identify vacant and abandoned parcels …


Strategy Design For Community Response To Distress And Decline Using Data Analytics, Michael P. Johnson Jr. Oct 2014

Strategy Design For Community Response To Distress And Decline Using Data Analytics, Michael P. Johnson Jr.

Michael P. Johnson

The foreclosure crisis in the U.S. has resulted in immense economic and social losses for individuals and neighborhoods. Some neighborhoods face long-term declines in population and economic activity that have been compounded by the foreclosure crisis. How can government and non-profit organizations design responses to neighborhood distress that reflect distinctive community characteristics and are consistent with long-term policy and planning goals? In this talk, I discuss alternative decision modeling strategies that support neighborhood health. Where foreclosure responses are likely to ensure that neighborhoods remain vital places for residential housing, productive strategies may include property acquisition and redevelopment. Other neighborhoods, however, …


Vessel Traffic Service (Vts): A Maritime Information Service Or Traffic Control System? Understanding Everyday Performance And Resilience In A Socio-Technical System Under Change, Gesa Praetorius Aug 2014

Vessel Traffic Service (Vts): A Maritime Information Service Or Traffic Control System? Understanding Everyday Performance And Resilience In A Socio-Technical System Under Change, Gesa Praetorius

Gesa Praetorius

Vessel Traffic Service (VTS) is a shore-side maritime assistance service that supports bridge teams in their safe navigation of port approaches and other areas that present navigational difficulties. The VTS is implemented in national waters and provides vessels with information through transmissions and broadcasts on Very High Frequency (VHF) radio. With a continued growth in the number, size and cargo volumes of merchant vessels, the role of the VTS has recently become a matter of discussion, and it has been argued that changes, such as implementing an aviation-like control system, would be of an enormous benefit for stakeholders and guarantee …


Parcel-Level Redevelopment Strategies For Distressed Neighborhoods, Michael P. Johnson Jr., Justin Hollander Oct 2013

Parcel-Level Redevelopment Strategies For Distressed Neighborhoods, Michael P. Johnson Jr., Justin Hollander

Michael P. Johnson

Certain distressed neighborhoods cannot support traditional residential-focused development. For these communities, we develop decision models for acquisition and redevelopment of chronically vacant lands and structures for primarily non-residential and greening uses. We address social benefits and costs of redevelopment strategies, parcel clustering to exploit economies of scale, and conflicting values among stakeholders. We illustrate our models using data from Baltimore, MD.


“Under Dangerous Conditions” – Safety Construction And Safety-Related Work Onboard Of Merchant Vessels, Gesa Praetorius, Monica Lundh May 2013

“Under Dangerous Conditions” – Safety Construction And Safety-Related Work Onboard Of Merchant Vessels, Gesa Praetorius, Monica Lundh

Gesa Praetorius

The following paper presents findings from a qualitative study conducted on board of two merchant vessels. Interviews and observations have been used to obtain insights in how safety is defined and promoted by the personnel working on board. The merchant vessel, the crew and the single mariner are identified to be part of a socio-technical system displaying three levels of system aggregation; person-centred, crew-centred, and vessel-centred. The common ground of a crew, an overlap of the individual mariners’ experience and knowledge, is identified as a basis for trust and predictability of action on board, which is a necessity to be …


A Mechanism For Organizing Last-Mile Service Using Non-Dedicated Fleet, Shih-Fen Cheng, Duc Thien Nguyen, Hoong Chuin Lau May 2013

A Mechanism For Organizing Last-Mile Service Using Non-Dedicated Fleet, Shih-Fen Cheng, Duc Thien Nguyen, Hoong Chuin Lau

Shih-Fen CHENG

Unprecedented pace of urbanization and rising income levels have fueled the growth of car ownership in almost all newly formed megacities. Such growth has congested the limited road space and significantly affected the quality of life in these megacities. Convincing residents to give up their cars and use public transport is the most effective way in reducing congestion; however, even with sufficient public transport capacity, the lack of last-mile (from the transport hub to the destination) travel services is the major deterrent for the adoption of public transport. Due to the dynamic nature of such travel demands, fixed-size fleets will …


Securing Access To Lower-Cost Talent Globally: The Dynamics Of Active Embedding And Field Structuration, Stephan Manning, Joerg Sydow, Arnold Windeler Mar 2013

Securing Access To Lower-Cost Talent Globally: The Dynamics Of Active Embedding And Field Structuration, Stephan Manning, Joerg Sydow, Arnold Windeler

Stephan Manning

This article examines how multinational corporations (MNCs) shape institutional conditions in emerging economies to secure access to high-skilled, yet lower-cost science and engineering talent. Based on two in-depth case studies of engineering offshoring projects of German automotive suppliers in Romania and China we analyze how MNCs engage in ‘active embedding’ by aligning local institutional conditions with global offshoring strategies and operational needs. MNCs thereby contribute to the structuration of field relations and practices of sourcing knowledge-intensive work from globally dispersed locations.Our findings stress the importance of institutional processes across geographic boundaries that regulate and get shaped by MNC activities.


Planning For Meals-On-Wheels: Algorithms And Application, Hakan Yildiz, Michael P. Johnson Jr., Stephen Roehrig Dec 2012

Planning For Meals-On-Wheels: Algorithms And Application, Hakan Yildiz, Michael P. Johnson Jr., Stephen Roehrig

Michael P. Johnson

Home-Delivered Meals provision, also known as Meals-on-Wheels, is a volunteer-staffed activity for which little strategic planning is performed. We develop a Memetic Algorithm to solve the Home Delivered Meals Location Routing Problem. This planning model addresses facility location, allocation of demand to facilities, and design of delivery routes, while balancing efficiency and effectiveness considerations. The case study presented on a large data set shows how trade-off curves, which are very useful for decision making, can be obtained by the method developed.

What Is A Strategic Acquisition? Decision Modeling In Support Of Foreclosed Housing Redevelopment, Michael P. Johnson Jr., Rachel B. Drew, Jeffrey Keisler, David Turcotte Aug 2012

What Is A Strategic Acquisition? Decision Modeling In Support Of Foreclosed Housing Redevelopment, Michael P. Johnson Jr., Rachel B. Drew, Jeffrey Keisler, David Turcotte

Michael P. Johnson

This paper describes and develops a model for calculating location-based strategic values of foreclosed properties considered for acquisition and redevelopment by community development corporations (CDCs). A property’s strategic value refers to its proximity to site-specific neighborhood amenities and disamenities (e.g. schools, public transit, distressed properties), given the relative importance of that proximity to CDC organizational and community objectives. We operationalize the concept of strategic value, and apply this concept to a salient public sector decision problem. Using data and value assessments from a CDC engaged in foreclosed housing redevelopment, we compute measures of strategic value for a set of acquisition …

Analysis Of The Risks And Benefits Of Flight Deck Adaptive Systems, Michael C. Dorneich, William Rogers, Stephen D. Whitlow, Robert Demers Jan 2012

Analysis Of The Risks And Benefits Of Flight Deck Adaptive Systems, Michael C. Dorneich, William Rogers, Stephen D. Whitlow, Robert Demers

Michael C. Dorneich

The objectives of this work were to identify human performance risks and benefits of adaptive systems through a systematic analysis and heuristic evaluation of adaptive system component types and characteristics. As flight deck automated systems have more access to aircraft data, sensor data, stored databases, communicated information, and real time flight crew inputs, as well as more ability to process that information in sophisticated ways to identify situational priorities and context, it is becoming more realistic for those automated systems to adapt their behavior based on context. Automated systems that can make such changes on their own are called adaptive …


Decision Support For Vessel Traffic Service (Vts): User Needs For Dynamic Risk Management In The Vts, Gesa Praetorius Dec 2011

Decision Support For Vessel Traffic Service (Vts): User Needs For Dynamic Risk Management In The Vts, Gesa Praetorius

Gesa Praetorius

Vessel Traffic Service (VTS) is a shore-side service implemented by a “Competent Authority to improve the safety and efficiency of vessel traffic and to protect the environment”. It is a service that operates through VTS centers, from which VTS operators monitor traffic, assist in navigational matters and provide information to all ships in a designated area. As VTS is provided by operators located on shore, they usually make use of several decision support systems to be able to monitor the traffic and to provide information to the vessels. Although several new tools and approaches have been introduced in the VTS …

Safety Within The Vessel Traffic Service (Vts) Domain. Understanding The Role Of The Vts For Safety Within Maritime Traffic Management, Gesa Praetorius

Gesa Praetorius

Vessel Traffic Service (VTS) is a shore-sided service implemented to promote the safety of navigation, safety of life at sea, and the protection of the marine environment. Its purpose is to work for safe and fluent traffic movements within a determined area, a VTS area. VTS is provided by VTS operators, skilled experts that provide vessels with information and advice, and work for the overall traffic organisation. Although VTS is regulated on an international level there are differences in how the service is provided in between countries, and even VTS centres. This licentiate thesis focuses on understanding the role of …


Evaluation Of A Shared Representation To Support Collaborative, Distributed, Coalition, Multilevel Planning, Michael C. Dorneich, David Mott, Ali Bahrami, Jitu Patel, Cheryl Giammanco Sep 2011

Evaluation Of A Shared Representation To Support Collaborative, Distributed, Coalition, Multilevel Planning, Michael C. Dorneich, David Mott, Ali Bahrami, Jitu Patel, Cheryl Giammanco

Michael C. Dorneich

This paper presents the extension and evaluation of a formal representation that enables planners at different levels of command, and in different functional area, to jointly share, develop, and modify plans. Planning has moved from a co-located, concurrent, small team activity to an activity that involves a large, culturally diverse, hierarchical, globally-distributed team. However, significant benefits of distributed planning can only come if the team is able to communicate and maintain a shared understanding of the commander’s intent, objectives, resources and constraints, as well as decisions made and justifications for planning options chosen or alternatives rejected. Effective automated support must …

Michael C. Dorneich

This paper presents an open loop adaptive system intended to address workload imbalances in future, high-workload flight decks. Air traffic in Europe is expected to more than double by 2020. New technologies being proposed will significantly add to pilot roles and responsibilities, and has the potential to add further periods of high workload to pilot operations. The CAMMI (Cognitive Adaptive Man Machine Interface) program addresses human factors priorities in the aviation domain by developing concepts that balance operator workload, support added future operator roles and responsibilities and resulting new task and information requirements, while allowing operators to focus on the …

Safety Is Everywhere-The Constituents Of Maritime Safety, Gesa Praetorius, Margareta Lützhöft Dec 2010

Safety Is Everywhere-The Constituents Of Maritime Safety, Gesa Praetorius, Margareta Lützhöft

Gesa Praetorius

Although maritime safety is one of the key terms in regulation, guidelines and recommendations, such as SOLAS (International Convention for the safety of life at sea (IMO, 1974), in the shipping domain, there is, to the best of our knowledge, neither an explanation of this specific type of safety nor any explicit understanding on how it is promoted by those who work on board of merchant vessel. This qualitative study approaches maritime safety from a crew perspective and discusses what constituents should be considered to be part of maritime safety.

Hybrid Rationale For Shared Understanding, David Mott, Cheryl Giammanco, Michael C. Dorneich, Dave Braines Sep 2010

Hybrid Rationale For Shared Understanding, David Mott, Cheryl Giammanco, Michael C. Dorneich, Dave Braines

Michael C. Dorneich

Understanding the reasoning of others is a key aspect to achieving a shared understanding when collaboratively solving a problem, such as the generation of a plan, and recent observations of military planners suggest that it plays a key role in the planning process. An example of rationale is described where a misunderstanding is only resolved by the joint exploration and cross-challenging of the rationale. A prototype tool is described that permits the creation and visualization of the basic rationale via the use of Controlled English (CE). Using the example, the paper explores mechanisms that could potentially make more effective use …


Making Plans Alive, Jitu Pater, Michael C. Dorneich, David Mott, Ali Bahrami, Cheryl Giammanco Sep 2010

Making Plans Alive, Jitu Pater, Michael C. Dorneich, David Mott, Ali Bahrami, Cheryl Giammanco

Michael C. Dorneich

Over the years, researchers have expended considerable effort in attempts to improve military planning, most notably via the provision of automated planning support tools. While there have been some successes (e.g. the DART system which was used for movement planning during Gulf war), planning still remains a very human‐orientated activity with little technical support. Why? A possible reason for this predicament is that researchers have not fully conceptualized the problem that planners face. For instance, a common approach has been to consider planning as a single process or a homogenous set of problems to be solved. Unfortunately, military planning is …


Senior Center Network Redesign Under Demand Uncertainty, Osman Ozaltin, Michael P. Johnson Jr., Andrew Schaefer Mar 2010

Senior Center Network Redesign Under Demand Uncertainty, Osman Ozaltin, Michael P. Johnson Jr., Andrew Schaefer

Michael P. Johnson

Senior centers off#11;er a variety of services to facilitate independent living of older adults. In the U.S., increasing suburbanization and aging of suburban residents necessitate reconfiguring senior services. We propose a two-echelon network of senior centers across large study areas and formulate a stochastic facility location/allocation model with mixed-integer recourse. We apply our model to Allegheny County, Pennsylvania, which has one of the oldest population in the U.S. Our model shows that a two-echelon network design is appropriate for increasing the occupancy of senior centers as community focal points while maintaining customized and accessible programming in small neighborhood areas.
