The formation of the Decision Sciences and Engineering Department in 1987 is a prime example of Rensselaer’s ability to anticipate the changing needs of the engineering profession. The department was created to (1) prepare engineers to design, develop, and implement complex systems and (2) to conduct research that leads to better understanding of how information technology and quantitative analysis and modeling can support individuals, groups, and systems in problem solving and decision making. DSES achieves these objectives by extending and integrating knowledge from the disciplines of industrial engineering, information systems, operations research, mathematical statistics, computational intelligence, bioinformatics, and systems engineering.

The Department of Decision Sciences and Engineering Systems offers programs in industrial and management engineering, service and manufacturing systems engineering, and operations research and statistics. Curricula in management engineering and/or industrial engineering have been offered since 1933. The interdisciplinary graduate program in operations research and statistics (OR&S) at Rensselaer was established in response to the rapid increase in the use of mathematical models for characterizing systems, understanding operations, and making decisions. Both a master’s and a doctoral program were initiated in 1967. However, in 1988, the department replaced the OR&S Ph.D. with a unique Ph.D. degree in Decision Sciences and Engineering Systems, reflecting the focus of the new department. The program in Manufacturing Systems Engineering was inaugurated in the fall of 1992, and has been updated to the current degree program in Service and Manufacturing Systems Engineering. This program is designed to emphasize modeling, statistical, computer, and management skills as they relate to service operations and the process of manufacturing. A common theme throughout these programs is the use of mathematical, statistical, and computational/simulation models to better understand engineering, managerial, operational, and physical processes.

Research and Innovation Initiatives

Manufacturing Systems

Faculty have developed methodologies and procedures for infrastructure and operating systems (e.g., production planning and control, scheduling, and dispatching in flexible manufacturing systems), simulation of production facilities, manufacturing logistics, materials handling engineering, facility design, information integration for design and manufacturing, control systems, and methodologies to integrate statistical quality control with computer graphics.

Service Systems

This area concentrates on the application of traditional and evolving industrial and systems engineering methodologies to the design and operation of service systems in both industry and the public sector. Areas of interest include simulation modeling and analysis, distribution and logistics, facilities design, work design, quality assurance, intelligent transportation systems, and engineering economic analysis. Also included is research in the deployment, allocation, and operation of urban service systems using computationally- intensive, real-time decision support approaches.

Information Systems

Information and decision support systems have been developed and extensively used for disaster preparedness and management of disasters (e.g., searches for ships lost at sea, earthquakes) and manufacturing enterprises (e.g., manufacturing-driven design and scalable adaptive integration of data- bases over wide area networks). New theory and methodologies for Internet-based information integration, e-commerce, data mining, and knowledge discovery are being developed. Decision support systems are being developed using a variety of knowledge engineering and computational intelligence tools. Also under development are methods, models, and technologies to aid in the planning and design of distributed information systems, information visualization, and user interfaces.

Mathematical Programming

Research topics include linear, nonlinear, integer, large-scale, multiple-objective, combinatorial, geometric, and stochastic programming. Of particular interest is research on the development and analysis of algorithms, computation, and the integration of uncertainty in optimization.

Statistics and Applied Probability

Research is conducted in the areas of real-time data fusion and analysis, data mining, knowledge discovery, and design of experiments—including optimality, efficiency, and robustness; nonlinear and robust estimation; statistical computing; probability; stochastic processes; queuing theory; reliability; quality control; and forecasting.

Facilitating these research programs are two research centers based directly within the Decision Sciences and Engineering Systems Department. Every department faculty member is involved in one or more of these research centers. In addition, several other faculty in the School of the Engineering, as well as in the other four schools, are also participating in activities conducted in the centers described below:

Center for Services Research and Education (CSRE)
http://www.dses.rpi.edu/research/csre.cfm
The goal of the CSRE is to enhance our understanding of the service sector and its function, and to educate students and managers seeking careers in the services industry, which accounts for more than three- quarters of the U.S. gross national product. CSRE faculty were one of the first groups to highlight the duality between services and manufacturing; many manufacturing methods are applicable to service systems and can be employed to enhance productivity and competitiveness. The CSRE takes a holistic approach to the multifaceted service sector and brings together experts from engineering, marketing, psychology, economics, and management policy and organization, among others. Experts examine the comon elements that characterize all aspects of the service sector and develop generic principles that apply across the wide spectrum of services, including the advancement of a focus in service systems engineering.

Rensselaer Statistical Consulting Center (RSCC)
http://www.dses.rpi.edu/research/rscc.cfm
The RSCC provides statistical planning and analysis services to Rensselaer researchers who require them. It also consults with companies and government agencies that require advice on state-of-the-art statistical and probabilistic methods and their applications. In addition, it allows graduate students to apply, in a supervised manner, established and new statistical and probabilistic approaches to real-world problems, and offers general and organization-specific short-term training programs and state-of-the-art courses in statistical methodologies and practices. The Center’s faculty represent a range of statistical expertise, and they have extensive research and consulting experience. These faculty members, together with talented graduate students, provide advice and guidance on the appropriate use of statistical and probabilistic methods, on a consulting or short course basis.

Special Undergraduate Opportunities

Cooperative Education Program
DSES encourages this option, which allows students to gain professional experience as part of the educational program. Additional information on co-op opportunities is included in the Educational Programs and Resources section of this catalog, as well as through the faculty adviser or the Career Development Center.

Graduate Programs
http://www.dses.rpi.edu/programs/masters.cfm

Master’s Programs

The Department of Decision Sciences and Engineering Systems offers two master’s level degrees, both of which can be earned within each of three curricula. These curricula and their individual requirements are described in the programs.

Doctoral Programs

http://www.dses.rpi.edu/programs/doctoral.cfm

Students working toward the Ph.D. in DSES may choose to major in industrial engineering, information systems, service and manufacturing systems engineering, operations research, or statistics. Advanced research and a dissertation in the chosen field are required in the doctoral program. In addition, Ph.D. students must complete the following:

• Institute requirements established by the Office of Graduate Education.
• Seminar in DSES research: Doctoral students must complete DSES-6900 during the fall semester of the first academic year of residency. This course is intended to introduce the student to the research environment at Rensselaer and to provide background on the process of doctoral research in DSES. Another intent of the course is to develop the student’s communication skills.
• Doctoral qualifying examination: The doctoral qualifying exam consists of two components — a written exam component and a research component. The written exam covers the core areas of DSES and the basis for this examination, including DSES 4530, DSES 4750, DSES 4760, DSES 4770, and DSES 6500 or their equivalents. A more detailed description of this and other required examinations is available from the DSES doctoral program director.
• Doctoral area requirement: Doctoral students must register for and complete course work in a selected major area. See the DSES doctoral program director for detailed documentation of DSES doctoral area requirements.
• Doctoral candidacy examination: Each student must take an oral candidacy examination after passing the DSES area requirement but before completing 45 credit hours of graduate work beyond the master’s degree. This examination tests the candidate’s background for the proposed research, appropriateness of the thesis research, and the ability of the candidate to successfully complete the research. The thesis research proposal must contain at least one result that meets journal publishing standards.
• Doctoral dissertation and defense: Each student must write a doctoral thesis and give a formal oral public defense.

Apart from the seminar in DSES research, doctoral area course requirements, and equivalent course material for the doctoral qualifying examination, there are no additional course requirements for the doctoral degree. However, the student is expected to develop in-depth knowledge in his/her dissertation area through appropriate course work, as well as supervised research. A Plan of Study is required, which must be approved by the thesis adviser and the DSES doctoral program director. Representative programs of study are available from the DSES doctoral program director.
