Pugh (1981) Concept selection: a method that works. This paper explores the use of an illustrative Concept of Operation and Pugh matrix as tools when evaluating concepts in the subsea domain. Start-up companies in general explore new applications or new technologies: an environment full of unknowns, uncertainties and other surprises. Continuous Improvement Toolkit Pugh Matrix Continuous Improvement Toolkit . architecture to support the next generation(s) of the product. The publication rate of about 23% Redesign of an In-Market Conveyor System for Manufacturing Cost Reduction and Design Efficiency Using DFMA Methodology, A System-of-Systems Bio-Inspired Design Process: Conceptual Design and Physical Prototype of a Reconfigurable Robot Capable of Multi-Modal Locomotion. Scribd is the world's largest social reading and publishing site. A prominent aspect of PuCC is presentation and dis-cussion of information in the form of a matrix. The resulting papers authored by these students identify challenges and effective practices suitable for knowledge transfer between industry and academia. Figure 6. In: Hubka, V. 497 – 506, Value of functional decomposition to estimate drilling rig time and to understand operational steps in subsea drilling. The rows of the matrix are labeled with concise statements of the criteria by which the design concepts can be judged. The publications, ... An example of a topic where we have a growing amount of publications is concept selection. At the end, the optimal design concept is determined for the liquid spraying machine. - All concepts should be compared at the same level of abstraction and in similar language. The columns of the Pugh matrix are labeled with a description, in drawings and text, of design concepts. 3D drawing of the Optimized Flow-line Spool and with a detail section of the, Figure 3.

Design for manufacturing and assembly is an engineering methodology that can reduce costs without compromising reliability, performance and time to market objectives. It is frequently used in engineering for making design decisions but can also be used to rank investment options, vendor options, product options or any other set of multidimensional entities. The Pugh Matrix was developed by Stuart Pugh, a professor and head of the design division at the University of Strathclyde in Glasgow. The Pugh Matrix is best used when it follows a series of steps. �v�&�X����pK�V�yt���\,X���g���X0���~�Z����Z,8��������笇�v�9�������WOߪSL��B�F!kꪏ��swB_8�q�C$��k��;����� www.citoolkit.com The Continuous Improvement A decision matrix is a list of values in rows and columns that allows an analyst to systematically identify, analyze, and rate the performance of relationships between sets of values and information. In this blog, we are going to look at a weighted version called the Pugh Matrix. -3 being worse that the base design and 3 being better than the base design. The Pugh Matrix is not intended to be a mathematical matrix; it is simply a format for expressing ideas and the criteria for the evaluation of these ideas in a visible, user-friendly fashion. XT is the so-called X-mas tree, the actual tree of. Choose or develop the criteria for comparison. - Based on a set of system requirements and goals. if you decide to build one of these devices then please understand clearly that you do so at your own risk and you, and only you, are responsible for your actions. Six out of 22 students, especially in the sub-sea equipment domain, chose the Pugh Matrix as technique for Concept Selection. Needs and concept analysis; A case study for subsea connections, Dag Jostein Klever, Needs and concept analysis; A case study for subsea connections, Master Pugh decision-making method is a clever way to make decisions. Step 1: List down the Criteria in a Vertical List. Search for more papers by this author. We apply the tools to a conceptual study of an interdisciplinary system expansion to encourage an unbiased holistic mindset of the decision makers. ���k� �/���x[H�-R.`��?Xd��u�u�x�4Um����쐞 z�%:j�Ju�1�p}�{:G����A�Y�@u��@�K��jm�C`��QОŮR�CV��(e��T-Z���Y�H� ��AROD�Y4V���'y(-ؘ�4 Conventional design paradigms for single design purpose may not be able to satisfy this requirement efficiently. We decided to do reverse architecting to be able to decide what changes are needed to the, Systems Engineering originated in the military and aerospace industry. Looking at the tally totals at the bottom of the matrix, we see that pizza delivery has two pluses, one minus, and one S. Factoring in relative weights of the criteria, we see that pizza delivery is still the best option when weighted, at six pluses and two minuses. Keyboard Shortcuts ; Preview This Course. signs and comparing them by a set of criteria that fits the problem. It involves different disciplines, materials, and types and designs of equipment. The Pugh matrix is a tool used to facilitate a disciplined, team-based process for concept generation and selection. Ready, Set, Dominate: Implement Toyota’s Set Based Learning for Prodcut Development. shows that these students contribute actively to the body of Systems Engineering knowledge. architecture, IDEF0 diagrams, Use Case Scenarios, Scenario Tracing and a geographical model. Search for more papers by this author . The optimum design was selected using Pugh controlled convergence method and further tested for its structural performance using finite element analysis. There are three main types of these systems, i.e., straight running, side flexing and multiflex. In this paper, the Pugh analysis is used to evaluate the candidate species against a baseline species (benchmark option) to select the champion species. We teach master students in Systems Engineering many methods and techniques that practi-tioners see as beneficial. valuable lessons learned by applying the industry-as-laboratory approach. Consequently the product has increased in complexity over these years and the architecture was not explicit available. Figure 7. The tools include context diagram, physical. completed master’s projects, with a detailed analysis of 40 papers that have been published in international conferences and journals. Joint gained a lot from the technology and qualification work that had been done. Anders Ekholdt, Concept Development Case Study, Optimized Test Cap for Connection The end product will be better than the product made initially. Pugh Matrix helps you come up with your potential final design. understand operational steps in subsea drilling, Master Project Paper, Buskerud University The Pugh chart is a tool used for evaluating multiple options against each other. The Pugh matrix helps determine which items or potential solutions are more important or ‘better’ than others. One method, called Pugh method, helps engineers in design decisions by establishing a procedure to choose the best design from the considered designs. It is worthwhile to know that equation 9 represents when one of the design concepts is taken as baseline. Klever looked for connection concepts that overcome these disadvantages. Philip Samuel. In this article, an integrated MADM model comprising of Fuzzy Analytic Hierarchy Process (FAHP), Fuzzy Pugh Matrix and Fuzzy VIKOR was developed and applied to evaluate conceptual designs of liquid spraying machine.
