Figure 1: Example of a completed Pugh Matrix Figure 1 shows a completed Pugh Matrix for four candidate design concepts called A, B, C and D which can be found along the top of the matrix. against a set of criteria by means of a matrix. In this paper, the Pugh analysis is used to evaluate the candidate species against a baseline species (benchmark option) to select the champion species. 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. This matrix, named after Stuart Pugh, is commonly used to evaluate design concept alternatives though it need not exclusively be used in these applications, we are going to demonstrate the use in a concept selection decision. methodology. This paper discusses the application of the Pugh matrix in six different cases in the domain of subsea equipment. Modern engineering problems require solutions with multiple functionalities in order to meet their practical needs to handle a variety of applications in different scenarios. We learned that "A3 Architecting Overview" is more usable than traditional document, and easier to use as it only required a single sheet of paper. Installation of a rigid flow-line spool, line connects the Pipe Line End Termination Structure (PLETS) with the manifold. The Pugh Matrix can then be used to choose specific aspects of the all the alternatives and then combine them to make the most feasible product. It involves different disciplines, materials, and types and designs of equipment. the battery charger of ron pugh thanks is due to ron pugh who has kindly shared the construction details of his very successful battery charger which is cop=13 when operating at 24 volts.
