To produce competitive advantage, a product has to be designed according to the criteria of consumer needs. The results of identifying consumer needs become technical requirements and target specifications in robust product design. The purpose of this research was to propose a robust design of gluten-free spaghetti product concept using the Taguchi method. The selection of factors and experimental levels utilized the zero one matrix and the evaluation matrix. The results showed that the priority quality attributes required by consumers include good product display, nutrition, acceptable taste, competitive prices, and made from local ingredients. Product specifications that are targeted at product quality are closer to commercial spaghetti products. Based on the experimental design, 4 factors and 3 levels with an orthogonal matrix (Taguchi) L9 (34) resulted in 9 product concepts. The selected concept has confirmed the quality of its spaghetti products.

A simulation approach to heat pump systems is proposed in this paper. The evaluation of working fluids is conducted. Moreover, the selected refrigerants are used in the simulation. Subsequently, the system is analyzed in terms of the coefficient of performance (COP) and energy efficiency. Some alternative refrigerants, instead of R22 used R290 refrigerent. It is described the selection of refrigerants adapted to each utilization, based on the thermodynamic and -physical properties, the technological behaviour, costs and use constraints as principal aspects of the environmental protection. Also, it is performed a comparative analysis in function of the total equivalent warming impact (TEWI) for some possible substitutes of refrigerant R22 used in various refrigeration and heat pump systems.

As a new generation of printing technology, thermal inkjet (TIJ) has been widely adopted to meet the increasing demand for high printing quality and efficiency at an affordable price. High air barrier tubes play an important role in the reliable operation of the printhead in a commercial thermal inkjet printer. Desired tube qualities include low stiffness and low pressure drop, along with others. Tube stiffness and pressure drop can be lowered through the selection of proper tube layer configuration, geometry and material properties. However, the existing tube design practice is highly heuristic and design results are not optimal. Furthermore, there is no robust design consideration in the current design, and it is hard to trace and compare the tube quality from different groups of designers. In this work, a comparative study using industrial examples is conducted to search for a reusable robust design methodology for TIJ tube design. Two cases using different optimization strategies are investigated. In case A, a performance based optimization strategy is used, and the design objectives are the target performances without variation consideration. In Case B, a robust design based optimization strategy is used, and the variations of the target performances are incorporated in the design objectives. A comparison of their results with the current practice shows that the optimization strategies can greatly improve the efficiency of the current tube design process. More important, the optimization strategy with variation consideration yields robust results and provides much richer design knowledge to support designers with various experiences to make better decisions.

Design of tolerances impacts quality, cost, and cycle time of a product. Most literature on deterministic tolerance design has focused on developing exact and heuristic algorithms to minimize manufacturing cost. Some research has been published on probabilistic tolerance synthesis and optimization. This paper presents the design of experiments (DOE) approach for concurrent selection of component tolerances and the corresponding manufacturing processes. The objective is to minimize the variation of tolerance stackups. Numerical examples illustrate the methodology. The Monte Carlo simulation approach is used to obtain component tolerances and tolerance stackups. Process shift, the worst case and root sum square tolerance stackup constraints, and setup reduction constraints have been incorporated into the proposed methodology. Benefits of the proposed DOE approach over exact algorithms are discussed. [S1087-1357(00)00202-1]

Abstract This paper proposes a design chart incorporating demanufacturing complexity metrics in robust design for recyclability. The proposed recyclability map relates sort complexity and material recovery efficiency for major subassemblies. The map helps designers to reduce product retirement costs and scrap through the appropriate selection of design modularity, material selection and disassembly strategy. Our method focuses on the dismantling process associated with multiple product families and generations and incorporates changes in recycling process technology capabilities. The recyclability map allows designers to understand the effects of uncertainties in product recycling and helps them to reach a strategy that is insensitive to these changes. The paper uses recycling of an inkjet printer as a validation example.
