Energy Systems Engineering Curriculum

A University of Maryland Field Committee has developed the interdisciplinary ESE curriculum. It will provide a coherent approach to energy engineering by equipping its students with the tools needed to conceptualize, analyze, design and integrate advanced energy systems. This approach is informed by a broad perspective on energy production, transmission and utilization technology options and trade-offs, and an appreciation for public policy and regulatory issues.

The curriculum will focus on the science and engineering that underpins energy conversion systems and will address engineering, science, and societal issues in the areas of fossil, nuclear, and renewable power generation, including hydrogen production and generation, energy usage, conservation and optimization, and sustainable development.

Research and education in the science and engineering of fossil, nuclear, and renewable energy production are current areas of strength at UMD and are perceived to be of critical importance to the future well being of this nation. ESE students will be uniquely qualified to participate in the formulation and implementation of future energy strategies and will provide a leadership cadre for the energy engineering community.

Participating students will be expected to complete the MS or PhD degree requirements of their respective departments' programs, while taking as many courses as possible from the ESE Curriculum. The final decision on course selection is reached in coordination with the student, his/her adviser and the respective department's graduate director.

Students participating in the ESE Curriculum must be accepted as advisee by one of the faculty participating in the ESE Curriculum and should have completed a BS in an engineering discipline.

Examples include: maximizing an organization's profit while also maximizing reliability and minimizing environmental pollution, or minimizing both time and cost on a project at the same time. This course is an introduction to the theory and algorithms behind optimization under such competing objectives, also called "multiobjective optimization". In this course, we explore the concepts of dominated solutions, Pareto optimal or "efficient" solutions, as well as several approaches to finding such points. We develop the theory for general nonlinear multiobjective optimization problems but concentrate the majority of effort on the linear case for the algorithms. In addition, we consider other multi-objective type models such as goal programming to solve problems with competing objectives. (Gabriel)

ENME 799 - MASTER THESIS RESEARCH (1-6)

ENME 808 - ADVANCED TOPICS IN MECHANICAL ENGINEERING (2-3)
Prerequisite: Consent of instructor. Advanced topics of current interest in the various areas of mechanical engineering. May be taken for repeated credit.

ENME 808D - AUTOMOTIVE CONTROL SYSTEMS (3)

ENME 808I - HYBRID ELECTRIC VEHICLES (3)

ENME 808O - ANALYSIS OF INTERNAL COMBUSTION ENGINES AND FUEL CELLS
(Former title: ADVANCED POWER PLANT FOR HYBRID ELECTRIC VEHICLES (2-3)
Prerequisite: None. This course will emphasize analysis of various power plant technologies being considered for the next generation of hybrid electric vehicles. The course will focus on the theory and design of power plants, including proton-exchange membrane fuel cells, direct injection diesel engines, and conventional spark ignition engines. A few weeks will also be set aside for looking at battery and electric motor technology being computational models for thermodynamic analysis and performance assessment of integrated hybrid vehicle power plants, both series and parallel configurations. Theoretical analysis will be presented in the context of outstanding problems related to hybrid electric vehicle power plant development and systems integration. Topics such as combustion cycle analysis and modeling of reacting flows will be presented in the context of specific technologies such as diesel engines or fuel cells. Students will perform an independent analysis on a hybrid system, which they will propose or extract from an industry design concept. Smaller assignments will allow the student to use the theoretical tools that are taught along with the individual technology topics to analyze a problem related to the specific technology (i.e., PEM fuel cells, DI diesels, etc...)

ENME 808R - ADVANCED ENGINEERING STATISTICAL METHODS (3)
Prerequisite: Elementary statistics. The course introduces the statistical methodology used 1) for the analysis, control and improvement of processes, and 2) to quantify certain system characteristics in vibrations and turbulence. The fundamental techniques that form the basis of this methodology include: designed experimentation, which is employed to obtain the input/output relationships of a process and to determine appropriate input levels; statistical process control, which is used for monitoring process performance; reliability techniques, which are employed to minimize or eliminate premature failure; acceptance sampling, which supports quality assurance, and the statistical analysis of time-varying random signals, which are used to describe the attributes of physical systems. Several of these techniques are implemented by student teams through laboratory activities. Software is employed to support these activities and to supplement the classroom material.

ENME 808X - ENGINEERING DECISION-MAKING (3)
Prerequisite: Graduate standing or permission of instructor. Engineers make decisions on a daily basis, some have consequences relevant to their current task and others join add to the portfolio of decisions accompanying a task as it moves through the enterprise.
Thus, engineering decision-making is at the interface between implementing
systems level performance requirements and enterprise level strategy implementation. Understanding the decision environment is vital to world-class engineering. This course studies decision production systems, which have an information flow that is governed by decision-makers who process information and make decisions under time and budget constraints, and teaches engineers how to identify their role within the decision making flow and be most effective in contributing to it.The course covers models and related methods for understanding and improving the behavior of these systems. Modeling of decision systems will be done by viewing the information and decision networks created during the course of key decision-making in the organization. Network flow models are one type of tool that will be uses to study decision production systems. Applications include product development organizations, manufacturing planning and control systems, and other organizations that operate in dynamic environments where there are multiple sources of uncertainty.
