Systems engineering is a discipline with methods and techniques to address complex problems. We want to study how Systems Engineering methods can help to address today's grand challenges, such as the energy problem. The first step is problem definition which aims at articulating the problem in its context as clearly as possible. Humanity will have to cope with the energy problem, one of the most critical challenges of humanity in this century. The energy problem itself is related to other challenges facing humanity like water, food and poverty. The key challenges concerning energy are climate change and other environmental impact of energy production and use, energy security, and long-term sustainable and affordable access to energy. The intention is to investigate the energy problem through applying system engineering practices aiming to reach a more clear, concise, and consistent understanding of the energy problem. This will help in both reaching a common understanding platform for all those involved in the energy problem and pave the way to identify the needs and thus suggesting and assessing solutions. Our first attempts to formulate a problem statement and to identify energy needs indicate that there are many assumptions in current literature.

The article will present an innovative educational project to introduce Systems Engineer-ing to third year’s students in industrial design engineering at the University of Twente. In a short period the students are confronted with new technology, namely sensors and actuators. They have to apply this technology in a complex situation, the design of a home climate system or an intelligent automobile. They work in large groups without tutor. In parallel a basic course on systems engineering is given to provide the students with tools for handling this situation. The aim is that students are forced to apply the systems engineering tools in a concrete situation, thus directly experiencing the benefits. The project is implemented and the article describes the context, the goals, the setup, and the experiences of both teachers and students. The article concludes with an evaluation of the first and second year it has been executed 1

The field of Engineering Systems is distinguished from traditional engineering design in part by the issues it brings to the top. Engineering Systems focuses on abstractions like architecture and complexity, and defines system boundaries very broadly. It also seeks to apply these concepts to the process of creating systems. This paper summarizes the role and influence of architecture in complex engineering systems. Using the research literature and examples, this paper defines architecture, argues for its importance as a determinant of system behavior, and reviews its ability to help us understand and manage the design, operation, and behaviors of complex engineering systems.

Operation is the user function and includes activities necessary to satisfy defined operational objectives and tasks in peacetime and wartime environments. Support includes the activities necessary to provide operations support, maintenance, logistics, and material management. Disposal includes the activities necessary to ensure that the disposal of decommissioned, destroyed, or irreparable system components meets all applicable regulations and directives. Training includes the activities necessary to achieve and maintain the knowledge and skill levels necessary to efficiently and effectively perform operations and support functions. Verification includes the activities necessary to evaluate progress and effectiveness of evolving system products and processes, and to measure specification compliance. Systems Engineering Considerations Systems engineering is a standardized, disciplined management process for development of system solutions that provides a constant approach to system development in an environment of change and uncertainty. It also provides for simultaneous product and process development, as well as a common basis for communication. Systems engineering ensures that the correct technical tasks get done during development through planning, tracking, and coordinating. Responsibilities of systems engineers include: • Development of a total system design solution that balances cost, schedule, performance, and risk, • Development and tracking of technical information needed for decision making, • Verification that technical solutions satisfy customer requirements, Milestones • Process entry at Milestones A, B, or C (or within phases) • Program outyear funding when it makes sense, but no later than Milestone B

can play an important role in driving the overall success of the system. This work seeks to create a multidimensional understanding of change activity in large systems that can help in improving future design and development efforts. This is achieved by a posteriori analysis of design changes. It is proposed that by constructing a temporal, spatial, and fi-nancial view of change activity within and across these dimensions, it becomes possible to gain useful insights regarding the system of study. Engineering change data from the design and development of a multiyear, multibillion dollar development project of an off-shore oil and gas production system is used as a case study in this work. It is shown that the results from such an analysis can be used for identifying better design and manage-ment strategies (in similar systems and projects) and for targeting design improvement in identified subsystems. The isolation and identification of change hotspots can be helpful in uncovering p...

The world, today, is passing through a period of great turmoil, socially, politically and environmentally, in spite of the numerous technological wonders that are taking place almost everyday. One needs to take a systems view of the influencing factors and their interactions and impacts in order to find the root causes of these problems and to arrive at viable policy options. System dynamics provides such an approach. The book authored by Professor Bala, Professor Fatimah and Professor Noh presents the principles of system dynamics in very simple language and illustrates its use with the help of five real-life case studies. This book is divided into two parts. The first part of the book presents, in a very simple way and starting with the fundamental principles, how complex interactions among the interacting forces can be modelled by capturing their cause-effect interrelations through dynamic models, how the models can be simulated and evaluated to depict reality and how policy interventions can be tested for testing their viability. Although the material covered in this part of the book is not new, the examples supporting the theoretical nuances of the subject covering population growth, grain storage, food security, commodity production, food relief, crop livestock, shrimp farming, crop irrigation and pollution are very interesting and appealing. In the second part of the book, the authors discuss case studies related to the areas of agriculture, aquaculture and environment in Bangladesh and Malaysia. Both hilsa fish and rice are important for the economy of Bangladesh, just as food security and cocoa production for Malaysia. The case study for solid waste management is well chosen as it is a perennial problem in third-world countries. This part of the book is illustrative of the power of system dynamics methodology as to how it can address many complex issues of today very easily. I believe that a newcomer to the field of system dynamics will find the book extremely useful and will be highly motivated to use system dynamics and systems thinking in understanding and addressing the issues that arise out of the behaviour of systems that are integral part of their lives.
