Systems Engineering broadly covers how to integrate different components in engineering systems. Applications range from operations research and mathematical solutions to business problems to control engineering, the basic theory and practice used to control diverse systems such as jet airplanes, electric power grids, or the nation's economy. The Systems Science and Engineering program is ideal for students interested in math, physics and computing; business, finance or financial engineering; or applied mathematics.

The Bachelor of Science in Systems Science & Engineering (BSSSE) program lays the engineering and mathematical foundations for modeling, analyzing and designing complex systems and highlights their applications in contemporary engineering and scientific application domains. Graduates will be competent in employing a versatile, interdisciplinary systems perspective to translate practical problem formulations into mathematical models, recognizing structural commonalities across diverse systems, and solving analysis and design objectives using suitable methods at the core of systems science and engineering. The basic methodological knowledge at the core of systems science includes mathematical competence and knowledge of systems analysis, control, design methods, numerical methods, differential equations, dynamic systems theory, automatic control theory, system stability, estimation, optimization, modeling, identification, simulation and basic computer programming. Graduates will have an engineering outlook and be able to interact fully with other engineers. They will also possess sufficient proficiency in computer use to design algorithms for simulation, estimation, control and optimization. 

The Bachelor of Science in Systems Science and Engineering (BSSSE) degree program is accredited by the Engineering Accreditation Commission of ABET.

BSSSE Degree Requirements

The course sequence designed to achieve the type of education outlined above requires at least 120 units, satisfies the residency and other applicable requirements of Washington University and the McKelvey School of Engineering, and meets the following program requirements:

  1. Common Studies program of the McKelvey School of Engineering: This includes courses in engineering, mathematics, physics, chemistry, humanities, social sciences and technical writing. The required chemistry sequence is Chem 111A-Chem 151 (recommended) or Chem 105-Chem 151.
  2. Engr 4501 Engineering Ethics and Sustainability (1 unit)
  3. Required courses in systems science and engineering: ESE 105 Introduction to Electrical and Systems Engineering (3 units); ESE 205 Introduction to Engineering Design (3 units)ESE 230 Introduction to Electrical and Electronic Circuits (4 units);ESE 318 Engineering Mathematics A (3 units) and ESE 319 Engineering Mathematics B (3 units); ESE 326 Probability and Statistics for Engineering (3 units); ESE 351 Signals and Systems (3 units); ESE 403 Operations Research (3 units) or ESE 415 Optimization (3 units); ESE 441 Control Systems (3 units); ESE 448 Systems Engineering Laboratory (3 units); and ESE 499 Systems Science and Engineering Capstone Design Project (3 units)
  4. Two of the following three computer science courses: CSE 131 Introduction to Computer Science (3 units); CSE 247 Data Structures and Algorithms (3 units); and CSE 132 Introduction to Computer Engineering (3 units). Students are encouraged to take CSE 131 and CSE 247. The other possible sequence is CSE 131 and CSE 132.

  5. One of the following two laboratory courses: ESE 447 Robotics Laboratory (3 units) or ESE 488 Signals and Communication Laboratory (3 units)
  6. 12 units in elective courses in systems science and engineering are required: ESE 400 through 428; ESE 437; ESE 440 through 459; ESE 470 through 497; ESE 497; ESE 502 through 529; ESE 540 through 559; SWCD 5660 Designing Sustainable Social Policies & Programs: A System Dynamics Approach. Up to 3 units of the following business courses may be part of the 12 units of systems science and engineering electives: OSCM 356 Operations Management, OSCM 458 Operations Analytics, OMM 576 Foundations of Supply Chain Management, and OMM 577 Information Technology and Supply Chain Management.
  7. 12 units in engineering concentration outside of systems science and engineering are required. These units must all be taken in one of the following engineering areas: Biomedical Engineering, Chemical Engineering, Computer Science & Engineering, Electrical Engineering (ESE 102; ESE 230 through 239; ESE 260 through 290; ESE 330 through 339; ESE 360 through 390; ESE 429 through 439; ESE 460 through 469; 490 through 496; ESE 498; ESE 530 through 539; ESE 560 through 589), or Mechanical Engineering & Materials Science. Of the 12 units, 9 units must be at the 200 level or higher. Sequences for concentrations in economics, mathematics, physics, pre-medicine and other fields can be arranged with special departmental approval to meet a student's specific needs. When a non-engineering discipline is chosen as the outside concentration, the student needs to pay special attention to the engineering topics unit requirement and make sure that enough engineering content is obtained from the other courses. The use of basic required courses to fulfill the requirement for an outside concentration is not permitted.
  8. The entire course sequence for the BSSSE, containing engineering topics of at least 45 units, must be completed. The number of engineering topics units assigned to undergraduate courses in the McKelvey School of Engineering vary from none (0) to the number of credits given to the course. For the precise number for each course, please refer to the table of Topics Units — Engineering Courses provided by Engineering Undergraduate Student Services.
  9. Limitations: No more than 6 units of the combined units of ESE 400 Independent Study and ESE 497 Undergraduate Research (including 497A and 497B) may be applied toward the SSE elective requirement (item 6 above) of the BSSSE degree. Any remaining combined units are allowed as free electives to satisfy the requirement for the total number of units.
  10. The courses taken to satisfy the following BSSSE degree requirements must be taken for a letter grade and not on a pass/fail basis: item 3 (required ESE courses), item 5 (elective laboratory course) and item 6 (elective ESE courses).
