“…Nevins and Whitney (1989) address the interactions between product design and production processes, with particular emphasis on assembly processes. In an influential article, De Fazio and Whitney (1987) extended the work of Bourjault (1984) to model the space of possible assembly sequences for a product. Boothroyd et al (1994) provide a methodology for designing components that are easy to assemble.…”

T his paper is a review of research in product development, which we define as the transformation of a market opportunity into a product available for sale. Our review is broad, encompassing work in the academic fields of marketing, operations management, and engineering design. The value of this breadth is in conveying the shape of the entire research landscape. We focus on product development projects within a single firm. We also devote our attention to the development of physical goods, although much of the work we describe applies to products of all kinds. We look inside the "black box" of product development at the fundamental decisions that are made by intention or default. In doing so, we adopt the perspective of product development as a deliberate business process involving hundreds of decisions, many of which can be usefully supported by knowledge and tools. We contrast this approach to prior reviews of the literature, which tend to examine the importance of environmental and contextual variables, such as market growth rate, the competitive environment, or the level of top-management support.

“…Commonly, AAP employs 2D engineering drawing and related assembly information to derive an APD diagram based on the contact-base or the feature-base relationships of the parts (Eng et al, 1999). De Fazio and Whitney adopted the concept of Bourjault (1984) to generate a complete set of assembly sequences (De Fazio and Whitney, 1987). They generated sequences in two stagescreating the precedence relations between liaisons or logical combinations of liaisons in a product and verifying liaison sequence.…”

This study proposes a three-stage integrated approach with heuristic working rules to assist the planner to develop a better assembly plan. In the first stage, Above Graph and transforming rules were used to create a correct Explosion Graph of the assembly models. In the second stage, a three-level relational model was developed to create a complete relational model graph and an incidence matrix. In the third stage, a mathematical model, based on a penalty index was formulated, and a revised minimum spanning table method was used to generate and evaluate a feasible assembly sequence. The example of a military system is presented to demonstrate the feasibility of the proposed method. The contribution of this study is based on a design for assembly potential applications of three-dimensional (3D) component models to assist manual or automatic assembly in a virtual environment, and allows the designer to recognize the relative position, constraints and relationships of 3D components using graph-oriented methods: Above Graph, assembly precedent diagram, and relational model graph. r
