“…In the evaluation of NC machine tools recycling also has no consensus and authoritative view, so to make an objective, comprehensive evaluation is more difficult. NC machine tools recycle evaluation is a system evaluation process, and is a series of quantitative scientific argumentation .Based on the composition of NC machine tools, this article proposes a method to evaluate recycle of NC machine tools based on fuzzy AHP(Analytical Hierarchy Process) , in order to achieve more scientific evaluation to the recycling of NC machine tools [16][17][18].…”

According to the idea of green manufacturing, recycling of CNC machine tools is researched. Flow chart of CNC recycling is analyzed, after several evaluation methods compared, the fuzzy analytic hierarchy process and linear weighting method are presented to evaluate the CNC machine tools recycling, evaluation indexes selected principles are researched, and then a comprehensive and rational evaluation index system of CNC machine tools recycling is established and a prototype system is developed based on theory study. It provides theoretical and technical reference for the recycling of CNC machine tools.

“…Given one product design, we could generate a set of disassembly paths. [24][25][26][27] Using the above method, we can obtain the best retirement plan and the overall cost for each of them. The optimal disassembly path for this design is the one whose overall cost is the least.…”

Sustainable industrial development seeks to meet current needs of society without compromising the ability of future generations to satisfy their own needs. In order to be able to sustain further the growth and development, we have to become more environmentally conscious in the development, manufacturing, use, and post-life treatment of products. Based on the concept of design for environment and multilifecycle engineering, this paper introduces a multi-lifecycle product recovery model, optimal retirement planning, and design selection methods. Two electronic products are used to illustrate the proposed concepts and methods. The results are useful in helping designers take into account the environmental impact into their product and process design activities.

“…The complexity in assembling and manufacturing a designed product has a tremendous effect on cost, profit and recyclability (Mok et al , 2000; Mok et al , 2001; Srinivasan et al , 1997; Lee et al , 1997). Product's design cannot be viewed as a stand‐alone process but should rather be treated as part of a larger product creation process that may be evaluated and modified before it is released for manufacturing and production.…”

PurposeVirtual product design has become a key technology in reducing costly design errors that are often difficult to detect manually. In order to evaluate product assembly in a virtual environment, it is important to link a product's design in CAD with the constrained complexity of assembly operations in CAM so that the design can be evaluated and modified in a virtual environment before production begins. The paper aims to focus on this.Design/methodology/approachThe proposed virtual system includes the following components: a product assembly coding model, named Open Structured Assembly Coding System (OSACS), that codes part‐mating operations for assembling any two parts in CAM; a rule‐based code extractor that identifies OSACS codes for assembling product from the part‐mating information encoded in Standard for the Exchange of Product Model Data AP‐203 CAD data; and an assembly‐sequence generator that generates a binary assembly‐tree for the designed product coded with OSACS assembly codes, representing assembly operations in CAM for product assembly.FindingsThe proposed system links the design phase in CAD with the manufacturing phase in CAM. Simulation studies were made using CAD Ap‐203 data files from an actual mobile phone housing assembly. A binary assembly‐tree assigned with OSACS assembly codes was generated for assembling the product. The assembling complexity between any two parts was coded with the unique OSACS assembly codes. The final binary assembly tree represents how the product is going to be assembled in CAM with the mating complexity encoded in the assigned OSACS codes.Research limitations/implicationsThe advantage of this virtual product assembly system is that a design can be validated first in a virtual environment without building the expensive physical production system. Moreover, additional design iterations can be performed in the same amount of time to improve product quality.Practical implicationsLinking product design in CAD with assembly operations in CAM can help realize significant cost savings by preventing future manufacturing problems. With the proposed virtual system, a company can prevent a potential problematic design from reaching production.Originality/valueThis paper introduces the conceptual design of a virtual system that links product design in CAD with assembly operations in CAM. This system provides a designer with a virtual product assembly process to evaluate a designed product.
