“…The idea and sketches form a concept that will be assessed through evaluation methods with a matrix based on assessment schedule, developed by Professor Stuart Pugh, known as the Pugh Concept Selection (Jalil, 2000;Ulrich & Eppinger, 2012) to obtain the final design concepts that meet specifications. Thus, based on the Assessment Schedule with the matrix, the selection of the final design concept will be translated into a selection of drawings by making improvements if necessary (Olabanji & Mpofu, 2014;Ulrich & Eppinger, 2012).…”

Product design is a complicated process and requires a systematic requirement and specification to produce sufficient quality to remain competitive. One of the most important components in the design process is Computer-Aided Design (CAD), which renders a detailed drawing in either two-dimensional (2D) or threedimensional modeling (3D). This paper discusses the conception of quality design to produce a creative design product. This study employed a systematic review to produce a framework of quality product design based on Computer-Aided Design (CAD). Out of 210 papers that were identified, 102 were reviewed and also 12 other relevant articles, books, reports, and documents, hence a total of 114 papers were included in this review. The reviews revealed that there are main aspect drivers of the product design, design process, design quality, customer need on the product, product evaluation, and design concept of quality products. The study also showed that the initial stage of idea-generating is an essential phase to produce innovative, creative and quality product design. This framework is useful as a guide for teachers to standardize product design concept and to assist Malaysian design and technology trainee teachers in producing a quality product design. Finally, this research proposes a conceptual framework based on our propositions. The proposed quality product design framework is beneficial to be used as a guideline for the Malaysian Technical Teacher Training Institute and policy makers to enhance the skills in the development of a quality product.Keywords: Product design framework, quality of product, design product concept, Computer-Aided Design 114 (100.0%) This studied systematic reviews were also analysed based on publication across the Scopus Q1 journal rankings. This information is shown in Table 3.

“…The reconfiguration of tools and fixtures is related to the use of the same tool and/or fixture for more than one part of the same part family, the design of tools and fixtures that can accommodate different orientations, or variable production capacity (e.g. variable number of mold prints) [46][47][48][49]. The reconfiguration of machines, workstations, and/or production cells can be associated with addition of devices and capabilities, more axis motions and larger tool magazines [39,50,51].…”

“…Similarly, the reconfiguration of material handling systems involves decisions related to dynamic combination and use of several types of material handling equipment (trucks, automated guided vehicles, rail guided vehicles, conveyors, cranes, and hoists), as well as modification of transportation layout in the plant [43][44][45]. The reconfiguration of tools and fixtures is related to the use of the same tool and/or fixture for more than one part of the same part family, the design of tools and fixtures that can accommodate different orientations, or variable production capacity (e.g., variable number of mold prints) [46][47][48][49].

Many advanced product manufacturing approaches have been introduced in the market in recent years. Thus, it is critical to develop modern techniques which can effectively familiarize budding minds with the latest manufacturing procedures. In fact, the contemporary training methods and advanced education practices are crucial to uphold the interest of the new generation as well as to equip them with state-of the art systems. There is a need for innovative ideas and effective methodologies to inculcate the desired competency and prepare students for prospective manufacturing set ups. In the latest Industry 4.0 paradigm, visualization technologies, especially virtual reality, have been emphasized to sustainably train and educate young students. This work presents a technique for utilizing the leading visualization method based on virtual reality in product manufacturing. It aims to acquaint students with the prominent concept of Industry 4.0, the reconfigurable manufacturing system (RMS). The RMS has been a demanding topic for the novice and, most often, amateurs are not able to grasp and interpret it. Therefore, this paper outlines the various steps that can be useful for students in order to anticipate the RMS design, interact with it, understand its operation, and evaluate its performance.

“…1). In actual fact, having an allencompassing design that satisfies all design requirements or features is a goal that seems not achievable because of the dynamic nature of the market that is swamped with diverse design due to customers' requirements (Olabanji & Mpofu, 2014;Renzi et al, 2015;Toh & Miller, 2015). Given this, the design process usually involves the development of different design concepts based on functional requirements and design features.…”

Deciding conceptual stage of engineering design to identify an optimal design concept from a set of alternatives is a task of great interest for manufacturers because it has an impact on profitability of the manufacturing firms in terms of extending product demand life cycle and gaining more market share. To achieve this task, design concepts encompassing all required attributes are developed and the decision is made on the optimal design concept. This article proposes the modeling of decision making in the conceptual design stage of a product as a multicriteria decision making analysis. The proposition is based on the fact that the design concepts can be decided based on considering the available design features and various sub-features under each design feature. Pairwise comparison matrix of fuzzy analytic hierarchy process is applied to determine the weights for all design features and their sub-features depending on the importance to the design features to the optimal design and contributions of the sub-features to the performance of the main design features. Fuzzified Pugh matrices are developed for assessing the availability of the sub-features in the design concept. The cumulative from the Pugh matrices produced a pairwise comparison matrix for the design features from which the design concepts are ranked using a minimum degree of possibility. The result obtained show that the decision process did not arbitrarily apportion weights to the design concepts because of the moderate differences in the final weights. .
