AbstractWhether the design of product innovation can highly match the customer demand is the key to extend the product life cycle, and it is also the basis for enterprises to carry out continuous production and operation. The first step of product innovation is to identify the relationship between customer demands and design factors of product innovation. This paper focuses on the problems of market control, due to the wide range and deep level of knowledge from customer demands in the process of product innovation. To better meet the customer demands, combined with Entropy Theorem, Prospect Theory and Grey Correlation Method, this paper puts forward a method of importance of design factors of product innovation considering customer demands. First, the Entropy Theorem and Prospect Theory are introduced to calculate the importance of demand factors from the perspective of customers and experts. Second, the priority ranking of design factors of product innovation from the perspective of customer demand is calculated through Gray Correlation Method and Fuzzy TOPSIS. Finally, this method is availability and feasibility thought taking the continuous innovation of electric vehicle as an example.

The development of digital technologies offers a wide range of opportunities to increase production efficiency, which relies on known tools and methods that transform in modern conditions. Many researchers note that the specialization most characteristic of complex knowledge-intensive industries has high prospects and is evident in all sectors of the national economy. Its combination with cooperation and outsourcing brings momentum to the development of both individual enterprises and the industry as a whole. It has been found that in light industry, which had a developed system of specializations, the return to this practice is difficult due to significant changes in the industries related to the liquidation of large mass production enterprises and the lag in the creation of digital twins, which are the basis at the stage of production preparation. Lost in the process of transition to a market economy, large production with a complete cycle is now successfully replaced by specialized small and medium-sized production, using high-performance equipment combined with modern digital technologies. It is obvious that the garment industry has entered a new cycle of development characterized by a high degree of specialization against the background of the application of digital technologies at all stages of the product life cycle. The significant lag in the application of digital technologies at the stage of production of light industry products is overcome, especially in the transition to additive technologies. It is noted that the digital shadow complements the information digital twin, which is especially relevant from the point of view of production. The introduction of digital technologies in specialized industries allows to achieve higher productivity and payback of invested capital than in standard production, where such investment is "blurred" due to the lag of related processes of the enterprise. It has been revealed that the modern stage of development of light industry is characterized by the application of fundamentally new technologies based on the creation of a digital twin and digital shadow, which create prerequisites for industrial application of additive technologies in industry. Key words: specialization, cooperation, digitalization, development of light industry

Abstract The design and aeromechanical assessment of turbomachinery blades and vanes comprises a wide range of complex processes that tend to be based on conventional deterministic methods. These processes often provide a ‘snapshot’ evaluation of the new component designs at the nominal operating conditions. While the deterministic methods can predict the high cycle fatigue (HCF) endurance with reasonable accuracy; they assume that the conservative safety factors applied to cover for the parametric variations, uncertainties and unknowns will not change during the product life cycle. This approach is intended to be conservative and in some cases may overlook the lack of robustness. The present paper proposes a robust design analysis approach based on probabilistic methodology for the aeromechanical assessment of rotor blades and stator vanes of turbomachinery. The robust design approach can account explicitly for the effects of design and manufacturing variability. This methodology can reduce the levels of conservatism in the deterministic approach and can provide a more thorough risk assessment. This paper offers a generalised aeromechanical analysis formulation based on probabilistic methods to evaluate the HCF capability of turbomachinery components. Herein, this methodology is demonstrated by using a typical stator vane of an aero engine compressor and it is based on Monte-Carlo and DOE simulations. The methodology consists of parametric sensitivity studies and identification of the most influential parameters that control the HCF endurance. Future ideas and roadmap of the aeromechanical probabilistic analysis capability development are also discussed.

The fast moving consumer goods included a wide range of items. The basic characteristics of the fast moving consumer goods result in that the consumers’ buying habit is: simple, rapid, impulsive, emotional. In the trend of market segmentation, enterprises have to make the products respond quickly to design and manufacture under the premise of meeting functions. In the design process, designers find out design point by axiomatic design method, and then through a modular design, rapidly assemble the various elements thereby to design series of products with distinctive features in batch, so as to help enterprises to extend the product life cycle.

The study about deformations of thermoplastic polyurethane membrane (desmopan membrane) is very important for a lot of industry domains (mechanic, transport, agriculture, chemistry, medicine, ...). This paper presents an original work about deformations by Finite Elements Method (FEM) analysis for desmopan membrane. Thermoplastic polyurethane (desmopan), an anisotropic material, is made in a very wide range of models and types. By Digital Image Correlation Method (DICM) we have determined mechanical characteristics [5].These with geometrical characteristics are required as input for FEM. Stresses [2] and deformations output of FEM, are necessary to calculate the fatigue resistance to limited durability to fracture [7]. After, we can study the membrane reliability of the desmopan membranes for diaphragm pumps.

Subject area Marketing. Study level/applicability Post Graduate. Case overview Rajiv Bapna and Pradeep Bapna co-founded Allied Electronics & Magnetics Limited (widely known as Amkette) in the year 1985 for the production of floppy diskettes in India. By the year 1995, Amkette was the largest selling floppy diskette brand in India. With the advent of new technology in storage media sale of floppy diskette observed a constant decline. By the end of year 2004, floppy diskettes completely vanished from the market. Amkette anticipated the changes in the computer peripherals market and introduced a wide range of products in storage media, wireless and wired peripherals, accessories and digital lifestyle products. After the launch of Evo TV on June 2012, Amkette was hopeful for a major success in digital lifestyle segment. Evo TV, a connected TV device, allowed consumers to use smart apps on their television sets and was a cost-effective substitute to Smart TVs. Amkette was betting very high on Evo TV for revenue generation and market development. Expected learning outcomes Following are the learning outcomes: to review the product life cycle of technology products, to understand evolving customers’ expectations and behavior, to assess the adoption process of innovative products and to explore the challenges associated with innovative products for market development.

AbstractWe have developed new polarizing coating materials and processes which enable the fabrication of polarizers for large-area liquid-crystal displays. The polarizing materials are novel discotic surfactants which self-assemble in aqueous solutions to provide a stable liquid-crystalline phase within a wide range of concentrations and temperatures. These lyotropic liquid crystals in an aqueous medium can be spread on a substrate surface by a variety of techniques including a knife-like doctor blade, a rolling cylinder, or a roll-to-roll method. Under the shearing force applied during deposition, the liquid crystals align on the substrate forming a dichroic polarizer. This alignment process allows continuous production of large-area polarizing films at low cost compared with the current technology that requires stretching of the films. Thin coatings can be applied to flexible plastic films, glass, or rigid plastic substrates. Direct coating of the polarizing material on glass eliminates several process steps in liquid-crystal display production since lamination of the polarizing film is no longer required. These new polarizing films have a high optical performance including a polarizing efficiency of above 98% and a dichroic ratio as high as 7.7.

Gold and uranium tailings (‘slimes’) dams and the adjacent polluted soils in the deep-level mining regions of South Africa (Carletonville, Klerksdorp and Welkom) were surveyed for the frequency of occurrence of naturally colonizing, actively introduced and persisting plant species. Fifty-six tailings dams with a combined area of 5864 ha. and a similar area o f tail- ings-polluted soils, were surveyed between July 1996 and March 1997. During the survey, 376 plant species and subspecies were recorded from the dams and adjacent polluted soils, with an additional  8 6  records obtained between 1998 and 2003 (i.e. a total of 462 taxa: species and infraspecific species). Overall, the most commonly represented families were the Poaceae (107 species and subspecies), Asteraceae (81). Fabaceae (55) and Anacardiaceae (16). with other families represented by just one to 14 species. Only 60 species were common to all three regions, and of these 24 had been introduced during rehabilitation attempts. Most of the species found on tailings were persisters or natural colonizers (53-88%, depending on substrate), with the vast majority being indigenous and perennial taxa (76% and 85% respectively), with semi-woody to woody growth forms (6 6% being resprouters, forbs, shrubs and trees). Less than 4% of the naturally-colonizing taxa found during the survey had also been introduced by vegetation practitioners. The majority of introduced plants were alien herbaceous taxa. The number and frequency of annuals was only high on recently vegetated sites, whereas annuals were rarely present on old-vegetated and never-vegetated dams. This list includes a wide range of indigenous plant species that may be suitable for phytoremediation of tailings dams and polluted soils due to their apparent tolerance of acid mine drainage and salinity.

This paper reports some aspects of the work being carried out on the NEUTRABAS project under the ESPRIT II European research program. The aim of this project is to specify and implement a neutral product definition database for large marine-related artifacts, covering a large part of the complete product life-cycle. The results of this research program will facilitate the effective exchange of product related data between disparate computer-based information systems, and hence promote a movement towards product life-cycle integration. The scope of the product model being developed as the basis for this integration is described in terms of its spatial and steel structural components, together with the implications for integration with other models of outfitting and engineering systems. The model is shown to encompass the wide range of product-related data which is associated with the various precommissioning stages of the product life-cycle. A suitable database architecture designed to support product data exchange and full life-cycle integration based on this product model is described and discussed.

The precisely perception of key customer requirements (CRs) is critically important for customer collaborative product innovation (CCPI) design. A novel approach is proposed based on the Kano model, interval 2-tuple linguistic representation model, and prospect theory. First of all, a Kano model is constructed to preliminarily screen the relatively important product function attributes. For the uncertain and vague information of CRs, an interval 2-tuple linguistic representation model is proposed to determine the weight of CRs. Then, the comprehensive prospects value is utilized for sorting the innovative programs based on the prospect theory. Finally, a numerical example is given to verify the scientific and validity of the proposed method.
