Multi-criteria selection of manufacturing processes in the conceptual process planning

Abstract

Process planning is one of the most difficult tasks in product development caused by the large number of technical, technological, economic, environmental and other criteria. Accordingly, the selection of manufacturing processes is a complex multi-criteria decision making problem since it considers a number of possible alternative manufacturing processes in addition to a large number of specified criteria. This paper represents the computer-aided methodology for the multi-criteria evaluation and selection of manufacturing processes at the stage of conceptual process planning. The developed methodology is primarily focused on the mapping of product design and manufacturing requirements. Manufacturing processes that fail to meet the given conditions on the basis of 10 criteria such as materials, production volume, productivity, dimensional accuracy, surface finish, etc., are eliminated according to the developed rules. Then, the multi-criteria evaluation and ranking of manufacturing processes is performed based on 5 criteria: manufacturing cycle time, process flexibility, material utilization, quality and operating costs. Based on this methodology, a system is developed for the multi-criteria selection of manufacturing processes, whose implementation is presented in the case of the hip joint endoprosthesis.

An Ontology-Enabled Case-Based Reasoning Decision Support System for Manufacturing Process Selection

“…(i) Multicriteria decision-making approaches (MCDM) rank available candidate processes based on a set of weighted criteria. Such approaches were suggested in [6,19,20]. (ii) Systematic approaches develop step-by-step procedures to facilitate the selection of materials and/or processes.…”

Integrated product-process design: Material and manufacturing process selection for additive manufacturing using multi-criteria decision making

“…It is suitable for multiple domains, especially manufacturing sector as it relies on the innate human inclination to conduct comparison by catering both subjective and objective attributes [45] . It is applied to material selection in gears [46] , selection of non-traditional machining processes, defining weight coefficients for selection of manufacturing processes in conceptual design stage for the body of modular hip joint endoprosthesis [47] , and selection of best material for design of lightweight aircraft metallic structures [48] .…”

An Integrated Open Approach to Capturing Systematic Knowledge for Manufacturing Process Innovation Based on Collective Intelligence

“…The technological developments of information and communication technology (ICT) and innovation theory have provided a more structured knowledge-driven environment for technicians and market decision-makers [40][41][42]. Computer-based applications, such as CAD/CAE/CAPP/CAM, help users to achieve better solutions and hence to introduce better products, processes, and services to the diversified markets [17,43,44]. Meanwhile, the combination of innovation theory and ICT to support technological innovation has become a new research category known as CAI [40].…”
