SE Taiz EM 01a1 Taiz master program Engineering & Management Course Systems Engineering Introduction Lecturer : John L Simons

SE Taiz EM 01a2 Just an example ! Enhancing safety procedures for a small airfield (i) What is safety? What affects safety? What to include/exclude? How to define a solvable problem?

SE Taiz EM 01a3 Just an example ! Enhancing safety procedures for a small airfield (ii)  Rather than separate, well- defined functions, systems today interact in complex ways to perform operational missions. Seemingly minor design errors can cost lives.  Error Cost explosion >>>  The discipline and concepts of systems engineering provide ways to manage this complexity  System (re)design is the key Definition1 System design 3 Preliminary design 10 Detail design50 Development200 Use500

SE Taiz EM 01a4 SE Today overview  About the course setup  What are systems? What is SE?  Applicability  Methodology  List of cases  List of caput items for research  List of journal articles

SE Taiz EM 01a5 What is Systems Engineering? From INCOSE … an interdisciplinary approach and means to enable the realization of successful systems. It focuses on defining customer needs and required functionality early in the development cycle, documenting requirements, and then proceeding with design synthesis and system validation while considering the complete problem. Systems Engineering considers both the business and the technical needs of all customers with the goal of providing a quality product that meets the user needs …

SE Taiz EM 01a6 What are systems? From INCOSE … A “system” is a construct or a collection of different elements that together produce results not obtainable by the elements alone. The elements include hardware, software, facilities, people, policies and information. The results include system level requirements, properties, characteristiscs, functions, behavior and performance …

SE Taiz EM 01a7 The blinder of System Engineers ! Everything is a system that can be redesigned to perform better !

SE Taiz EM 01a8 The focus of SE SE (1) deals with real life problems of problem owners and (2) advocates systematic solving these problems by designing a system. This being the case, a university course cannot equally pay attention to these two aspects since lecturer and students practice SE methods and techniques under laboratory conditions.

SE Taiz EM 01a9 Yet another view on SE ! A more abstract view on SE emphasizes the translation process of a world problem Pw to a model problem Pm to a model solution Sm to a world solution Sw and the necessity to define these milestone products and their relations.

SE Taiz EM 01a11 The role of SE in the E&M master  Methods in this course elaborate on methods in courses OR, Methods engineering, Product design and Production systems.  The courses Strategic management and Methods of research reflect on methods of SE.  SE offers the student a range of models, methods and techniques which can be used in the individual master’s research.

SE Taiz EM 01a12 About the course setup (i)  Student working groups of 2-3 students  Self-activity with (E-)coaching  Group assignment covers model analysis for case, caput study, journal article review, methodology questions  Each group presents two times (for active audience) with feedback from lecturer  Report on time on target i.e. in this two week period

SE Taiz EM 01a13 About the course setup (ii) Daily four hours schedule  Introduction of theoretical key concept by lecturer and/or students  Groupwise case study (caput, journal, methodology) discussion  Presentation of results (case, caput,jornal article) by groups  Feedback on approach, methodology, real life SE organisations

SE Taiz EM 01a14 Cases (from the Blanchard book)  Failure mode effects and critically analysis FMECA  Fault tree analysis FTA  Reliability centered maintenance RCM  Maintenance task analysis MTA  Level of repair analysis LORA  Design evaluation of alternatives  Life cycle cost analysis LCCA. > If such a case is chosen the focus is on the managerial aspects of SE. The approach must be applied to a new problem (preferably real life example from organization of the student).

SE Taiz EM 01a15 Other cases (full text from lecturer)  Spread of sleeping sickness. Model (system of differential equations) of populations of active and non-active malaria flies and infected and non- infected humans in a rural area. Analysis of spreading speed and stability points.  Waiting queues for study loan processes. Simulation of queues based on arrival and processing assumptions. Analysis via random number generation. Modeling of university schedule quality.  Definition and evaluation of schedule quality. Least squares model fitting to survey results of perceived quality. See /1996/j.h.oldenkamp/ /1996/j.h.oldenkamp/ > If one of these last cases is chosen, the focus shifts to applying a mathematical method and reflecting on the applicability.

SE Taiz EM 01a16 SE is a team effort ! staring or doing

SE Taiz EM 01a17 Student’s goals for today (and tomorrow)  Form groups of 2 students. Each group chooses a case (use your preferences)  Each group must choose two presentation slots in the coming two weeks  Each group presents its problem definition, analysis, solution (1) and its caput or article (2) according to schedule  Schedule fixed after today  Choice of caput and journal article during days 1 and 2

SE Taiz EM 01a18 Presentation slots  Day 2 (first week) up to day 11 (second week)  Each day has two slots of max 20 minutes and max 10 slides  Each group chooses two slots (one for case, other for caput or article)  First come first serve  Quality groups choose early slots for optimal feedback

SE Taiz EM 01a19 Further plans for today (second hour)  Forming groups, choosing a case study, applying for presentation slots.  Start of group discussion. Anything goes.

SE Taiz EM 01a20 Further plans for today (third hour)  Continuation of group discussion. > At the end third hour each group must have at least one slide with three remarks/questions for plenary discussion (SE field, case, plans, caput, confusion...)

SE Taiz EM 01a21 Further plans for today (fourth hour)  Plenary discussion on items raised by groups  Feedback and tips for groups from lecturer
