This paper presents a new method of using a convolutional neural network(CNN)in machine learning to identify brand consistency by product appearance variation.In Experiment 1,we collected fifty mouse devices from the past thirty-five years from a renowned company to build a dataset consisting of product pictures with pre-defined design features of their appearance and functions.Results show that it is a challenge to distinguish periods for the subtle evolution of themouse devices with such traditionalmethods as time series analysis and principal component analysis(PCA).In Experiment 2,we applied deep learning to predict the extent to which the product appearance variation ofmouse devices of various brands.The investigation collected 6,042 images ofmouse devices and divided theminto the Early Stage and the Late Stage.Results show the highest accuracy of 81.4%with the CNNmodel,and the evaluation score of brand style consistency is 0.36,implying that the brand consistency score converted by the CNN accuracy rate is not always perfect in the real world.The relationship between product appearance variation,brand style consistency,and evaluation score is beneficial for predicting new product styles and future product style roadmaps.In addition,the CNN heat maps highlight the critical areas of design features of different styles,providing alternative clues related to the blurred boundary.The study provides insights into practical problems for designers,manufacturers,and marketers in product design.It not only contributes to the scientific understanding of design development,but also provides industry professionals with practical tools and methods to improve the design process and maintain brand consistency.Designers can use these techniques to find features that influence brand style.Then,capture these features as innovative design elements and maintain core brand values. 展开更多

In the present paper, we derive some third-order differential subordination results for analytic functions in the open unit disk, using the operator Bcκf by means of normalized form of the generalized Bessel functions of the first kind, which is defined as z(Bκ+1^c f(z))′= κBκ^c f(z)-(κ- 1)Bκ+1^c f(z),where b, c, p ∈ C and κ = p +(b + 1)/2 ∈ C / Z0^-(Z0^-= {0,-1,-2, … }). The results are obtained by considering suitable classes of admissible functions. Various known or new special cases of our main results are also pointed out. 展开更多

By building a duopoly model based on product differentiation, both of the clean firm's and the dirty firm's performances are studied under the assumptions that consumers have different preferences for the product environmental attributes, and that the product cost increases with the environmental attribute. The analysis results show that under either the case with no environmental regulation or that with a tariff levied on the dirty product, the clean firm would always get more profit. In addition, the stricter the regulation is, the more profit the clean finn would obtain. This can verify that from the view of product differentiation, a firm could improve its corporate competitiveness with environmental management. 展开更多

Supposing that the consumer preference compiles with triangular distribution instead of uniform distribution, we establish the model of vertical product differentiation. The simulation shows that there exists stable equilibrium along with unstable equilibrium. In stable equilibrium, high quality products gain an advantage over low quality products. In unstable equilibrium, the former does not possess an apparent advantage in competition, likely to be at a disadvantage. In order to evolve from unstable equilibrium to stable equilibrium, it is necessary for firms to solve such problems as high prices and consumers' perception of scarcity on product qualities. In general, both product qualities and firm profits increase with the consuming capacity and quality perception, and the latter more rapidly. 展开更多

Focusing on B2B market, this paper studies the effect of product differentiation on business model perlbrmance. After interviewing several experts and analyzing numbers of distributing questionnaires. the author discovered that product differentiation has a positive effect on business model performance. Through SEM. it is revealed that product differentiation at each level have positive effect on business model, with different effect weight. The main contributions of this research are summarized as follows: Firstly, the proposed model of the product differentiation on business model performance lays the basis for scientific measurement of product differentiation and its effect on business model performance; Secondly, this research ranks the importance of product differentiation at different level in B2B market; Finally, this research provides a good reference for enterprises to update their product strategy for better business model performance. 展开更多

In this paper, we consider a general quasi-differential expressions t1,t2 Tn, each of order n with complex coefficients and their formal adjoints are t1+,t2+- x+ on [0, b) respectively. We show in the direct sum spaces LZ(Ip), p = 1,2 N of functions defined on each of the separate intervals with the case of one singular end-points and under suitable conditions on the function F that all solutions of the product quasi-integro differential equations are bounded and LZw -bounded on [0,b). 展开更多

In many equipment manufacturing industries, firms compete with each other not only on products price, but also on maintenance service. More and more traditional products oriented finns are offering their customers products bundled with maintenance service (P&S bundles). In this study, we examine finns' incentive to offer customers products bundling with long-term maintenance or repair support service in a duopoly competitive environment. When providing P&S bundles, a finn need to determine the service level (in terms of average response time guarantee for the service in this paper) to offer and needs to build a service facility to handle the maintenance service requirements. Based on the analysis of three sub-game models, we characterize the market conditions in which only one firm, both finns or neither finn will offer P&S bundles. Finally, we analyze the affects of serval market factors on firms' strategy choices. 展开更多

We analyze product differentiation in a multi-dimensional model with non-uniform consumer distribution.The level of product differentiation is measured by both unit transport costs and firms'locations.Our analysis concerns both measures.First,fixing firms'locations,we show that equilibrium prices can increase or decrease with unit transport costs.The overall result depends on the interplay of a shifting effect and a rotating effect-the latter exists only in multi-dimensional models.Second,fixing unit transport costs,we find that under non-uniform distribution,there may exist no equilibrium where firms maximize differentiation on one dimension but minimize differentiation on other dimensions.Instead,there may exist an equilibrium where firms choose intermediate locations,contrary to common findings in existing studies which assume uniform distribution. 展开更多

This paper brings together a number of robust trade models to shed some light on the likely evolution of the global automotive industry. Vertical product differentiation, intra-industry trade and fragmentation of production leading to international outsourcing are important features of the existing global automotive sector. The global automotive sector will most likely experience groundbreaking changes over the coming decades. The sector is confronted with a multidimensional technological revolution spurred by radical product innovation, shifts in customer demand and government incentives. A dominant driver will be growing public concern about climate change. China and India might well become leading players by 2050, if not earlier. 展开更多

This article analyses on why China Mobile and China Unicom have chosen price war rather than tacit collusion these years. On the basis of the analysis on factors that influence tacit collusion, and combined with the facts of wireless communication market, the author suggests that the market asymmetries, cost asymmetries, and product differentiation are the basic factors, which trigger price competition between the Chinese wireless operators. By constructing a game model based on Chum rate, this article discusses how these factors cause a fight between the operators and how vigorous the price competition will be. At last, the author suggests that to keep vigor in this industry, continuous structural adjustment is essential. Besides, the number portability policies may cause tacit collusion. 展开更多
