Abstract:

This paper presents the authors’ perspectives on some of the open questions and opportunities in Process Systems Engineering (PSE) focusing on process synthesis. A general overview of process synthesis is given, and the difference between Conceptual Design (CD) and Process Design (PD) is presented using an original ternary diagram. Then, a bibliometric analysis is performed to place major research team activities in the latter. An analysis of ongoing work is conducted and some perspectives are provided based on the analysis. This analysis includes symbolic knowledge representation concepts and inference techniques, i.e., ontology, that is believed to become useful in the future. Future research challenges that process synthesis will have to face, such as biomass transformation, shale production, response to spaceflight demand, modular plant design, and intermittent production of energy, are also discussed.

Abstract:

Exploring wide multi-disciplinary solution spaces to create conceptual design solutions is a difficult task for human designers due to lack of sufficient multi-disciplinary knowledge. A viable approach would be to develop a computer-aided system to synthesize the wide variety of knowledge for a given design task. However, the existing design synthesis systems are mainly domain-specific, focusing on conceptual design synthesis in a single or few limited disciplines. Therefore, this article introduces the development of a knowledge-based system for multi-disciplinary conceptual design synthesis, including the establishment of a knowledge base for organizing multi-disciplinary principle solutions and a design synthesis algorithm. The implementation of a prototype software is also reported, with the conceptual design of a solar fountain as a demonstrative case. The results of the case study show that the system can automatically and conveniently generate multi-disciplinary conceptual solutions.

Abstract:

Research into conceptual design of mechanical systems has evolved as an area of interest since last few decades. Conceptual design plays a significant role as an early stage of design to produce designs with higher quality by economically exploring a larger solution space. Several attempts have been made by researchers to automate the conceptual design synthesis process using computer support. However, most of that work has been focused on single state design problems. This paper deals with multiple state mechanical design problems and proposes a systematic method for synthesizing a larger solution space. A web-based tool is developed to guide designers through the step-by-step synthesis process by providing automated retrieval of initial solution proposals and modification rules.

Abstract:

Conceptual design of mechanisms has attracted a number of research efforts in recent years due to its significance in product development. However, existing approaches for automated conceptual design of mechanisms are either prone to a loss of optimal solutions or inextensible to achieve conceptual design of complex mechanisms. This paper is devoted to developing a comprehensive and extensible methodology for automated conceptual design of mechanisms utilizing a design prototype synthesis methodology. To support automated mechanism synthesis effectively, the traditional morphological matrix is improved as a motional function matrix (MFM). In addition, a mechanism prototype knowledge base is developed to provide systematic knowledge support for conceptual design decision-making. Based on the integrated MFM, an exhaustive mechanism synthesis algorithm is developed to yield as many solutions as possible to desired functions to facilitate the discovery of novel and optimal combinatorial solutions. To curb the possible combinatorial explosion from the exhaustive search, a performance constraint verification approach is proposed to help designers filter out combinatorial solutions violating performance constraints, followed by a satisfaction degree-based approach for evaluating the total performances of combinatorial solutions according to the performances of their subsolutions. An automated mechanism conceptual design prototype system is developed and a design case is presented to illustrate the feasibility and practicality of the proposed methodology.

Abstract:

The purpose of this paper is to present a design approach based on the geometric constraints of joints for synthesizing differential mechanisms with two degrees-of-freedom, including some mechanisms with the same functions but distinct structures. The concept of virtual axes is presented. And, there are five steps in the design process. Step 1 is to decide fundamental entities by the properties of existing mechanisms and the technique of number synthesis, and 10 suitable fundamental entities of differential mechanisms are available. Step 2 is to compose geometric constraints, and 14 items are obtained. Step 3 is to compose links, and 15 items are derived. Step 4 is to assign fixed constraints for inputs or outputs, and 15 results are found. The final step is to particularize the obtained events by the properties of existing mechanisms and the structures of fundamental entities. As a result, 8 feasible results for differential mechanisms with two degrees-of-freedom and two basic loops are obtained in which 2 are existing designs and the other 6 are novel.

Abstract:

This thesis suggests the use of tools from the disciplines of Computational Linguistics and Knowledge Representation with the idea that such tools would enable the partial automation of two processes of Conceptual Design: the analysis of Requirements and the synthesis of concepts of solution. The viewpoint on Conceptual Design developed in this research is based on the systematic methodologies developed in the literature. The evolution of these methodologies provided precise description of the tasks to be achieved by the designing team in order to achieve successful design. Therefore, the argument of this thesis is that it is possible to create computer models of some of these tasks in order to partially automate the refinement of the design problem and the exploration of the design space. In Requirements Engineering, the definition of requirements consists in identifying the needs of various stakeholders and formalizing it into design speciႡcations. During this task, designers face the problem of having to deal with individuals from different expertise, expressing their needs with different levels of clarity. This research tackles this issue with requirements expressed in natural language (in this case in English). The analysis of needs is realised from different linguistic levels: lexical, syntactic and semantic. The lexical level deals with the meaning of words of a language. Syntactic analysis provides the construction of the sentence in language, i.e. the grammar of a language. The semantic level aims at Ⴁnding about the specific meaning of words in the context of a sentence. This research makes extensive use of a semantic atlas based on the concept of clique from graph theory. Such concept enables the computation of distances between a word and its synonyms. Additionally, a methodology and a metric of similarity was defined for clarifying requirements at syntactic, lexical and semantic levels. This methodology integrates tools from research collaborators. In the synthesis process, a Knowledge Representation of the necessary concepts for enabling computers to create concepts of solution was developed. Such, concepts are: function, input/output Ⴂow, generic organs, behaviour, components. The semantic atlas is also used at that stage to enable a mapping between functions and their solutions. It works as the interface between the concepts of this Knowledge Representation.

Abstract:

A numerical design synthesis methodology for new generations of combat aircraft has been developed. It incorporates advanced technology in the form of design for low observables. Aircraft capable of being modelled with this methodology will have internal or external Weapons carriage, side mounted intakes, a straight-tapered trapezoidal wing, aft-mounted tail with the option of single or twin ns, and one or two engines with rectangular or axisymmetric nozzles. The design methodology incorporates sufficiently accurate and realistic algorithms for the calculation of the geometry and the estimation of the aerodynamic, mass and performance properties of the aircraft. The inherent flexibility of the design permits the examination of a wide range of configurations whilst maintaining the accuracy required to examine minor changes in the design requirements. A numerical optimization routine was linked to the synthesis, allowing the determination of optimum aircraft design variables for a given set of mission and performance requirements. Results were obtained showing the usefulness of this design tool for setting up parametric trend studies. The numerical accuracy, flexibility of configuration options and high level of advanced aircraft technology of this synthesis make a significant contribution to the continuing development of automated design tools.

Abstract:

La caracterización de arreglos de micro hilos de óxido de Zinc (ZnO) se ha realizado con la finalidad de diseñar una batería experimental que utiliza la energía de deformación como fuente de energía. El principio de almacenamiento está basado en la compresión simple de un muelle cuya fuerza de compresión se encuentra asociada a la energía que es cosechada. Mediante el mismo principio se propone la compresión de un arreglo de nano hilos de ZnO crecidos de forma alineada perpendiculares al sustrato de crecimiento, funcionando como muelles elásticos que almacenen energía en un medio enteramente mecánico. El ZnO se ha elegido por ser un material en el que se pueden crecer nano estructuras con forma de hilos, barras y filamentos de manera sencilla y de bajo coste a través de un método de síntesis llamado método hidrotérmico. Tomando en cuenta las mejores muestras alineadas de micro hilos de ZnO, se realizó un proceso para su caracterización mecánica en dos fases principales. La primera fase consiste en el estudio estadístico para dimensionar su morfología y tamaños así como su densidad de crecimiento media por toda la muestra. En segundo lugar se llevó a cabo la realización de la aplicación de la teoría lineal elástica que después fue corroborada y replicada con simulaciones de elementos finitos (FEM). Las condiciones de contorno consideradas como comportamientos posibles en los micro hilos de ZnO fueron libre-empotrado y articulado-empotrado. Finalmente los micro hilos se sometieron a pruebas de compresión simple utilizando un nanoindentador comercial, para llevar a cabo el análisis experimental puntual de las propiedades del material del que se conforman y así determinar la discrepancia con el modelo teórico así como su capacidad de almacenamiento de energía real.
The synthesis and characterization for a ZnO array have been done in this research, with the aim of design an experimental mechanical battery, which uses the strain energy as energy source. The storage principle is based on a common spring, which is loaded by the force associated to the energy to be harvested. By following the same principle our approach is based on the compression of a ZnO fine wires array (ZnOfws), grown vertically on a substrate surface, working as regular springs and storing energy entirely on the mechanical domain. The ZnO has been chosen as a “spring-like” material, due to the fact the fine wires growth is cheap and simple, using an aqueous synthesis called “hydrothermal method”. By taking the best aligned ZnO array obtained, the dimensions measurement was carried out through a statistically method, based on the SEM images analysis. From this study the average growth density, diameters and lengths were obtained. Afterwards, a mechanical study for a single fine wire was done, applying the linear elastic theory and FEM simulations. In order to, analyze the most likely mechanical behaviors for a single ZnOfw. Finally, the fine wires samples were submitted to a mechanical characterization through the nanoindentation technique, with the objective of see the real deformation levels and, mechanical energy storage capability that they have. As an alternative to this measurement a customized compression set-up was fabricated, in order to, analyze the mechanical behavior of a ZnOfws array at a larger scale.

Abstract:

A computer-aided technique is developed in this thesis to systematically generate concepts for sensors of a wide variety. A database of building blocks, based on physical laws and effects that capture the transduction rules underlying the working principles of sensors, has been developed to synthesize concepts. The proposed method uses the database to first create a concept-space graph and then selects concepts that correspond to paths in the graph. This is in contrast to and more efficient than existing methods, such as, compositional synthesis and graph-grammar synthesis, where solution paths are laid out first and then a concept-space graph is generated. The research also explores an approach for synthesis of concepts for closed-loop sensors, where a quantity is sensed indirectly after nullifying its effect by using negative feedback. These sensors use negative feedback to increase the dynamic range of operation without compromising the sensitivity and resolution. According to the literature, generation of un-interesting solutions is a major drawback of the building block-based synthesis approaches. In the proposed approach, this shortcoming is mitigated substantially by using some rules. For a number of the concepts generated, in the sensor problems attempted, we found that those concepts were already implemented in existing patents; thus emphasising the usefulness of the concepts produced. The synthesis approach proposed new, feasible sensor concepts, thereby indicating its potential as a stimulator for enhancing creativity of designers. Another important problem is to improve the robustness of designs. Robustness can be achieved by minimizing the side effects. Side effects are defined as unwanted effects that affect the intended working of the sensor. The research presents an algorithm that (a) predicts the potential side effects for the synthesized concepts of sensors; (b) aids in quantifying the magnitude of the side effects, thus helping the designer to predict the significant side effects; and (c) suggests ways to improve the robustness of the design.

Abstract:

Conceptual design synthesis is part of the conceptual phase of the design process, which focuses on creating alternative, candidate solutions. Conceptual design phase has the greatest influence on the cost and characteristics of the final product; an excellent detailed design based on a poor and inappropriate concept can never compensate for the inadequacy of the concept. Conceptual design is difficult, which currently relies on the designer’s intuition and experience to guide the process. A major issue in conceptual design is that often not many alternative candidate solutions are explored by the designer during the design process. The major reasons for this are the tendency to delimit a design problem area too narrowly and thus not being able to diversify the possible set of design solutions, possible bias towards a limited set of ideas, and time constraints. Many researchers recommended a thorough search of the design space for developing a good solution; this requires generation of a large solution space. Mechanical devices (mechanisms and machines) have fascinated the mankind throughout recorded history. Conceptual design synthesis of mechanical devices is difficult even for humans, and is also difficult to completely automate. In a single state design task, the relation between an input and output are fixed, but in a multiple state design task, the relation is not fixed. Much of the current research has been focused on supporting synthesis of single state devices, in particular where the device has to convert an input motion into an output motion. Synthesis of multiple state device is in contrast rather poorly understood and supported. Complete automation is unlikely to be possible; developing support taking into account the strength of computer and and human is important mechanical device is not adequate the biggest source for understanding of this process, and for its subsequent support, is human designers. The concept of state for a mechanical device is explained in detail by analyzing the existing multiple state mechanical devices. An operating state described by elemental functions (defined by efforts- motions of input and output components) and their associated Understanding and Supporting Conceptual Design Synthesis of Multiple State Mechanical Devices configurations and configuration changes. However, study of current literature indicates that little has been known about the actual processes carried out by designers in synthesizing multiple state devices. The main objectives of this thesis, therefore, are as follows: (1) understand the multiple state device design synthesis process carried out by designers, and (2) develop methods for supporting synthesis of multiple state mechanical devices to enhance the number of solution alternatives generated. Empirical studies are conducted to understand how designers currently carry out multiple state design tasks. Ten designers are given a multiple state design task and asked to generate as many solutions as possible. The designers are asked to think aloud while carrying out their synthesis processes. All these synthesis processes are video recorded, and analyzed to identify what activities are involved in the multiple state design synthesis, what the inputs are to each activity, and what the outcomes are from each activity. It has been found from these studies that design fixation is quite common, and the majority of the designers pursued developing a single solution to the given design task. A generic descriptive model of the multiple state mechanical device design synthesis process, explaining how this is carried by the designers, is developed. Based on this model, a prescriptive model of multiple state design synthesis process, explaining how the multiple state synthesis process should be carried by designers in order to develop a large solution space, is also developed. The prescriptive support, for synthesizing a large solution space for a given multiple state design task, has been evaluated. Eight engineering designers participated in the evaluation procedure, where each designer had to synthesize solutions for two, given multiple state design tasks. Results indicate that use of the prescriptive support, even without the power of a computational implementation, may have been beneficial in helping designers develop feasible solutions in a greater number of cases in a more efficient manner (that is, by considering fewer solution proposals and in similar amounts of time). All the designers who participated in this exercise gave a positive feedback regarding the prescriptive support. However, in none of the design sessions did the designers develop more than one feasible solution. This, along with various other comments from designers, indicates that a faster and more proactive support – implemented on computer – might be more useful in supporting the tasks. The various aspects for a potential computer support are discussed.

Abstract:

Mathematics instruction for young children should begin early, elaborate on and mathematize children’s everyday mathematics, promote a meaningful integration and synthesis of mathematics knowledge, and advance the development of conceptual understanding, procedural fluency, and use of effective strategies. The affordances provided by computer programs can be used to further these goals by involving children in activities that are not possible with traditional methods. Drawing on research and theory concerning the development of mathematical cognition, learning, and teaching, high quality mathematics software can provide a productive learning environment with several components: (1) useful instructions and demonstrations, scaffolds, and feedback; (2) mathematical tools (like a device that groups objects into tens); and (3) virtual objects, manipulatives and mathematical representations. We propose a five-stage iterative research and development process consisting of (1) coherent design; (2) formative research; (3) revision; (4) learning studies; and (5) summative research. A case study ofMathemAntics, software for children ranging from age 3 to grade 3, illustrates the research and development process. The chapter concludes with implications for early childhood educators, software designers, and researchers.

Abstract:

It is well recognized that conceptual design is the most critical stage of product development process. Yet, existing MEMS (Micro-Electro-Mechanical Systems) design synthesis models or methods are very restrictive in supporting MEMS conceptual design, in that they are only applicable to specific or specific types of designs, where building blocks for design synthesis have to be pre-specified by the designers. To address this problem, this paper proposes a MEMS conceptual design synthesis framework, which consists of a behavior representation that caters for the multidisciplinary MEMS design characteristics and a design synthesis strategy that is able to explore multidisciplinary phenomena for the development of MEMS initial design concepts. The behavior representation incorporates information of both physical interactions and chemical/biological/other reactions that take place during a MEMS device’s behavioral process. The design synthesis is accomplished by both forward and backward synthetic search strategies in identifying the relevant phenomena for the development of the desired behavioral processes. The framework can be used to develop both the physical structure of a MEMS device and the substances that are necessary for the chemical/biological/other reactions. A software prototype implementing the proposed framework is also presented, followed by a MEMS design case study.

Abstract:

Synthesis of spatial compliant mechanisms for morphing surfaces in three dimensions is challenging as it not only involves meeting the kinematic requirement for spatial shape change, but also providing support against external loads. In three dimensions, there are no existing insightful techniques for synthesis, and the computational approaches are rendered complex. This paper builds on a new insightful technique to synthesize compliant mechanism topologies by visualizing a kinetostatic field of forces that flow through the mechanism geometry. Such a framework when extended to three dimensions, enables a maximally decoupled synthesis framework of shape morphing compliant surfaces, where a primary mechanism meets the shape change requirement, and an auxiliary mechanism provides the required support under external loads. The preliminary design guidelines are implemented using an immersive Virtual Reality based design tool, and verified using finite element simulations for several spatial compliant mechanisms. This design framework is deemed useful for a larger class of shape morphing structures beyond the examples presented in the paper.

Abstract:

In this paper, we investigate a methodology for the conceptual synthesis of compliance at a single point based on a building block approach. The methodology lays the foundation for more general compliant mechanism synthesis problems involving multiple points of interest (i.e. inputs and outputs). In the building block synthesis, the problem specifications are decomposed into related sub-problems if a single building block cannot perform the desired task. The sub-problems are tested against the library of building blocks until a suitable building block is determined. The synthesized design is composed of an assembly of the building blocks to provide the desired functionality. The building block approach is intuitive and provides key insight into how individual building blocks contribute to the overall function. We investigate the basic kinematic behavior of individual building blocks and relate this to the behavior of a design composed of building blocks. This serves to not only generate viable solutions but also to augment the understanding of the designer. Once a feasible concept is thus generated, known methods for size and geometry optimization may be employed to fine tune performance. The key enabler of the building block synthesis is the method of capturing kinematic behavior using Compliance Ellipsoids. The mathematical model of the compliance ellipsoids facilitates the characterization of the building blocks, transformation of problem specifications, decomposition into sub-problems, and the ability to search for alternate solutions. The compliance ellipsoids also give insight into how individual building blocks contribute to the overall kinematic function. The effectiveness and generality of the methodology are demonstrated through a synthesis example. Using only a limited set of building blocks, the methodology is capable of addressing generic kinematic problem specifications.

Abstract:

Abstract In automated synthesis of electro-mechanical systems, considering both behavioral and spatial information is a challenging problem. This paper describes an approach to generate first-cut spatial configurations of electro-mechanical assemblies that satisfy side-effect constraints and also adhere to the basic behavioral interconnectivity specified during conceptual design. This approach is based on the branch-and-bound search technique and tightly integrated with conceptual design of electro-mechanical systems. We believe that by integrating behavioral and spatial information, one can provide a framework for effective exploration of a large number of design alternatives and increase the effectiveness of solid modelling-based assembly tools.

Abstract:

While there are multiple discussions regarding what HSS is, the most popular and cited definition is that of the World Health Organization (WHO). It says: “HSS is the process of identifying and implementing the changes in policy and practice in a country’s health system, so that the country can respond better to its health and health system challenges. Additionally, it is also an array of initiatives and strategies that improves one or more of the functions of the health system and that leads to better health through improvements in access, coverage, quality, or efficiency” (WHO, 2019, p. 11). Scope of this rapid review: The aim of this rapid review is to provide a rapid synthesis of the different frameworks and approaches that have been designed and proposed for HSS. The synthesis includes frameworks conceptualised by international development and health agencies as well as those proposed by individual researchers and smaller organisations. While there are multiple frameworks, many of these frameworks build upon the WHO (2007) HSS framework and adapt this as per their needs and perspectives. Furthermore, considering the shake-up of health systems due to the COVID 19 pandemic, this review also includes frameworks which have reconceptualised HSS in response to the pandemic’s impact on health systems. Key findings: The rapid review found that a multitude of HSS frameworks exist in the public health literature. Some of these frameworks are modified from the WHO (2007) building blocks frameworks or use this framework as a basic conceptual foundation to propose new frameworks. Furthermore, there is some conflation of health systems frameworks and HSS frameworks in the literature. This review, however, has focused specifically on HSS frameworks. Evidence base: The frameworks and approaches were extracted from agency documents, journal articles and grey literature.

Abstract:

At any point in the drug development process, systematic reviews and meta-analysis can provide important information to guide the future path of the development programme and any actions that might be needed in the post-marketing setting. This report gives the rationale for why and when a meta-analysis should be considered, all in the context of regulatory decision-making, and the tasks, data collection, and analyses that need to be carried out to inform those decisions. -- There is increasing demand by decision-makers in health care, the biopharmaceutical industry, and society at large to have access to the best available evidence on benefits and risks of medicinal products. The best strategy will take an overview of all the evidence and where it is possible and sensible, combine the evidence and summarize the results. For efficacy, the outcomes generally use the same or very similar predefined events for each of the trials to be included. Most regulatory guidance and many Cochrane Collaboration reviews have usually given more attention to assessment of benefits, while issues around combining evidence on harms have not been as well-covered. However, the (inevitably) unplanned nature of the data on safety makes the process more difficult. -- Combining evidence on adverse events (AEs), where these were not the focus of the original studies, is more challenging than combining evidence on pre-specified benefits. This focus on AEs represents the main contribution of the current CIOMS X report. The goal of the CIOMS X report is to provide principles on appropriate application of meta-analysis in assessing safety of pharmaceutical products to inform regulatory decision-making. This report is about meta-analysis in this narrow area, but the present report should also provide conceptually helpful points to consider for a wider range of applications, such as vaccines, medical devices, veterinary medicines or even products that are combinations of medicinal products and medical devices. -- Although some of the content of this report describes highly technical statistical concepts and methods (in particular Chapter 4), the ambition of the working group has been to make it comprehensible to non-statisticians for its use in clinical epidemiology and regulatory science. To that end, Chapters 3 and 4, which contain the main technical statistical aspects of the appropriate design, analysis and reporting of a meta-analysis of safety data are followed by Chapter 5 with a thought process for evaluating the findings of a meta-analysis and how to communicate these.
