Systems Engineering Homework 1  Homework submission deadline: 20:00, 2014‐April‐11  Discussions with fellow students are encouraged. However, the homework must be completed and submitted on an individual basis. If two or more students submit identical homework solutions, each student will get only a fraction of the grade for this assignment.  Late policy: first late day will reduce your assignment grade by 50%. Additional days will reduce the entire homework grade to 0. If you have a special circumstance, please contact jianjun.gao@sjtu.edu.cn ahead of the submission deadline.  Control the font size to 10 or 11. Question 1 (15) We have discussed some of the characteristics of systems—hierarchy, interaction, emergence, dynamics, and interdisciplinary. As a CLGO fellow, you must have worked with complex systems or observed them. Please choose an example of a complex system, and discuss how these characteristics of the systems apply to this example. You should discuss at least 3 characteristics. You can also add other system characteristics that you recognized beyond what was discussed in the lecture. In addition to explaining how each characteristics apply to the system example of your choice, please also comment on whether these characteristics make the system desirable, challenging, or both. Hint: you may want to connect this question to the project proposal assignment. Question 2(15) During the lecture 3, we have discuss the case that a company want to develop a sports training monitoring systems to help professional sports athlete. You can also search the related products and documents on the web to know more about this system. Identify 3 three stakeholder of this systems. For each stakeholder, design 4 questions to explore their needs and expectations. For each of the question, please describe your objective (why you ask this question). Question 3 (70 points) Before start working on this question, please first spend some time to familiarize yourself with the Boeing 787 Lithium Ion battery pack problem. A number of good references have been sent to you. This reference list is meant to help your work with the best information that we

have.It isn't meant to limit the information source.You should look for additional useful information if you see the need. 2.a(20 points) Who are the stakeholders for the Li-ion battery pack design and maintenance?What are the needs of these stakeholders?List at least three stakeholders.Draw a boundary diagram for each stakeholder that clearly shows their internal system elements and external interfacing elements.For each stakeholder,identify at least 3 needs.Briefly explain why these needs exist.Provide references to the sources of your information. 2.b(25 points) Choose two operational concepts for the Li-ion battery system.Draw a functional diagram for each scenario.Draw N2 Diagram to identify the interface relationship of these functions 2.c(25 points) Generate a list of system requirements,based on your answers to Questions 2.a and 2.b above.Use tools such as QFD to map the relationship between the system requirements and the Stakeholder needs.These requirements may be written in a draft format,and you will be asked to refine them in the next question using the "good requirements"quidelines. 2.d(10 points) Choose two system requirements from Question 2.c,and expand them into full-length requirements that meet the listed attributes of good requirements as listed in section 4.2.2.2 of the INCOSE SE Handbook v3.2.2.Use"TBD"where you do not know the range of the specification values.Make sure the requirements are verifiable by describing how you might test your product against these requirements.However,it is not required that you provide the technical details of the testing procedures.This question intends to reinforce your understanding if what is a good/bad requirement,not your technical knowledge about the electricity substation design. Optional Bonus Question(10 points) Do you see conflict among the needs of various stakeholders involved in the Li-ion battery pack design?Discuss if safety would naturally occur if each stakeholder just focuses on its needs.Use the concept of hierarchy and control to illustrate how such conflict may be resolved/balanced

You should look for additional useful information if you see the need. 2.a (20 points) Who are the stakeholders for the Li-ion battery pack design and maintenance? What are the needs of these stakeholders? List at least three stakeholders. Draw a boundary diagram for each stakeholder that clearly shows their internal system elements and external interfacing elements. For each stakeholder, identify at least 3 needs. Briefly explain why these needs exist. Provide references to the sources of your information. 2.b (25 points) Choose two operational concepts for the Li-ion battery system. Draw a functional diagram for each scenario. Draw N2 Diagram to identify the interface relationship of these functions. 2.c (25 points) Generate a list of system requirements, based on your answers to Questions 2.a and 2.b above. Use tools such as QFD to map the relationship between the system requirements and the Stakeholder needs. These requirements may be written in a draft format, and you will be asked to refine them in the next question using the “good requirements” guidelines. 2.d (10 points) Choose two system requirements from Question 2.c, and expand them into full-length requirements that meet the listed attributes of good requirements as listed in section 4.2.2.2 of the INCOSE SE Handbook v3.2.2. Use “TBD” where you do not know the range of the specification values. Make sure the requirements are verifiable by describing how you might test your product against these requirements.
