David J. Singer

Research Interests

Dr. Singer’s new research direction in the area of Complexity Theory and Network Science within the Naval ship design context is on track. This new area of research has recently been awarded an ONR grant totally 2.4 million dollars. Additionally, Dr. Singer is currently pursing opportunities to expand the newly developed Spectral Markov Decision Process framework to the include methods that will enable rapid military engagement modeling within the early stage design of naval combatant design. Lastly, Dr. Singer is pursuing opportunities to expand his research to the automotive and aerospace domains.

Set-Based Design in Naval Ship Design
Dr. Singer has expertise in Set Based Design (SBD) as applied to ship design. As a critical member of the Navy’s Ship-to-Shore Connector (SSC) program during its preliminary design, he educated the design team on SBD theory and managed the SBD process within the overall design effort. This was the first time SBD was employed in a Navy design acquisition program and Dr. Singer has been involved with the introduction and use of SBD in the Navy’s Ohio replacement program, CGx program and DDG 51 Flight III programs. Since the successful implementation of SBD on SSC, Dr. Singer has significantly advanced SBD methods. Drawing off his previous work in applying fuzzy logic agents to SBD, he extended the method by introducing Type-2 Fuzzy Logic to add consideration for uncertainty in the evaluation of the set range. Most recently, Dr. Singer applied design space mapping methods and Markov Decision Process methods to SBD. The combination of these two approaches improves a designer’s ability to understand how a decision to narrow the design space impacts the relationships among design variables and performance metrics.

Ship Arrangements
The University of Michigan Intelligent Ship Arrangements (ISA) system has been delivered and will become part of the U.S. Navy’s Rapid Ship Design Environment which is the main ship design and analysis software used by the Navy. Dr. Singer’s current ship arrangement research has shifted away from the current trajectory toward higher-fidelity 3-D layout models and re-vector toward a perspective that focuses on understanding and inherently respects the fundamental underlying relationships among elements within those models. This is being achieved through the use of network science to re-envision the layout problem from a new perspective. In this view, design relationships are information inputs into layout-related analyses rather than only post-processors for evaluating layouts. This is consistent with existing design processes where human designers attempt to keep relevant relationships in the back of their mind at all times to inform decisions.

Design Decision Frameworks
As stated earlier, Dr. Singer’s research is focused on one primary goal; “how can the design of complex Naval combatants be improved?” This has been achieved by focusing on how complex design teams interact and evolve a design as well as developing methods that bring traditional late stage design activities into early stage design. These goals are being achieved through the development of early stage design decisions frameworks. The current novel design evaluation frameworks are:

• Network Theoretic Approach Design Framework
• Ship-Centric Markov Decision Process Framework
• Utility-Based Real Option Framework
• Multidisciplinary Decision Making Heuristic Framework
• Dynamic Control of Flexible Ship Production Framework

Responsibilities

Dr. Singer is the sole faculty within the department responsible for teaching the required ship production portion of naval architecture and marine engineering curriculum. He teaches both a required undergraduate (NA 260) and graduate (NA 562) courses in ship production. In 2006 Dr. Singer completed a major revision of NA 562. NA 562 was transformed from a low quality shipyard operations course to a true graduate course that goes through the systematic description of the underlying behavior of manufacturing systems put into the context of shipbuilding. The course addresses shipyard and boat yard business and product strategy definition, operations planning and scheduling, performance measurement, process control and improvement strategies.
