Introduction
Published in Yogesh Jaluria, Design and Optimization of Thermal Systems, 2019
The design phase of the enterprise is where much of the effort and time are spent and determines, to a large extent, the final outcome of the undertaking. The design process could and usually would seek technical inputs from many other groups within the company, particularly from the research and development section. Such inputs may concern information on available materials and their properties, on new techniques and processes, on the analysis and evaluation of different designs, and on possible solutions to various problems encountered during design. The design effort may be concerned with a single device such as a heater; a component or subsystem of the system, such as a pump; or the overall system itself, such as a solar energy water heating plant. Though the design of components is an important consideration in design, in this book we are mainly concerned with the design of systems consisting of several components interacting with each other. System design may be directed at different types of systems such as electronic, mechanical, thermal, or chemical. The design of thermal systems is obviously of particular interest to us.
From Virtual to Real—A Progressive Simulation-Based Design Framework
Published in Gabriel A. Wainer, Pieter J. Mosterman, Discrete-Event Modeling and Simulation, 2018
System design is a process evolving a system from an initial conceptual formulation, to model development and verification, to physical prototyping and experimentation, and to the final system realization in the field. For large scale distributed real-time systems, such a process is not easily achieved. This is because of factors such as distributed processing, temporal requirements, limited resources, concurrent environmental entities, and high-reliability requirements. The increasing complexity of these systems calls for systematic methods as well as supporting environments to design, test, and measure them. To serve this purpose, modeling and simulation (M&S) are frequently employed. With M&S, the system under development and its environment can be modeled. This allows designers to test and evaluate the models on computers.

Methods for system design can be divided into three categories: strategies, procedures, and techniques. While some methods strictly belong to one category, others are combinations of methods from one or many categories. The focus in this chapter is on holistic methods that aim to address all needs during the design phase. These holistic methods are often based on the whole design process, with amended techniques, strategies, and procedures; e.g., systems engineering, KTH-IPM [17] Design for Six Sigma [18], ModArt [19], Manufacturing System Design Framework Manual–MIT [20]. These methods try to aid the designer through the greater part of the system design phase and interrelate other common support systems wherever necessary.

System design is a process of mapping from a set of stakeholder needs, via the functions that contribute to meeting those needs, to a description of the physical system that will meet those functions (Suh 2001). A function is generally considered to be what a system does (de Weck, Roos, and Magee 2011). In ship design, subsystems defined by volumes and weights are assigned to functions, and then integrated and balanced within the ship hull (Erikstad and Levander 2012). The design process results in a description of the ship in the form of drawings and models dictating shipbuilding, as well as plans describing how the ship should be operated. After delivery, the vessel enters the operational phase, where it performs the functions necessary for the mission at hand. The operational phase constitutes the greatest part of the ship lifecycle, whose phases are shown in Figure 1.

System performance can be improved by system design. For example, the inclusion of a carbon-enriched saturated zone in biofilters can mitigate against the impacts of extended dry periods, providing a more stable anaerobic zone for better nutrient removal and reduced nutrient leaching after extended dry periods (Zinger et al. 2007b; Zinger, Fletcher, and Deletic 2007a; Blecken et al. 2009a). Expanding system size could also increase the retention time, but may not always be feasible in space-constrained urban areas, and may also have the effect of accentuating impacts of long dry periods on system function. The passive nature of nature-based SCMs thus intrinsically limits their ability to respond to variations in operating conditions.
Development and Evaluation of an Attendance Tracking System Using Smartphones with GPS and NFC

The presented App system aims to help the educational systems in colleges become more effective and productive. The student attendance tracking system uses smartphone devices based on the technological trends over the last few years. Many people use smartphones, not only in Taiwan but also everywhere in the world. In the universities of Taiwan, professors sometimes ask students to do research in class by using their smartphones. Expecting each one to have an Android smartphone, we have designed the methodology based on the Android device with GPS and NFC. After the system requirements are specified correctly, the system design is performed, and then the system implementation is finished.
