Recently, lots of EDI-VAN (Electronic Data Interchange-Value Added Network) companies challenge to convert their business systems into Web-based e-business frameworks to avoid high cost and closed structure of EDI system. This research proposes e-Transformation strategies for EDI-VAN companies to adopt Web-based e-business standard frameworks such as ebXML (e-business using XML) and RosettaNet. Four migration strategies for EDI companies are presented, and their properties are described in detail. Transformation procedures of two representative strategies are also provided fur the convenience of medium-sized companies. The result of this work can be used as a practical guideline for EDI companies to develop there own transformation strategy suitable to its scale and capability, while minimizing the impacts on the pre-existing business processes.

In this study, we investigated how to distinguish customer delivered value to re-purchasing in fierce B2C industry. To identify key managerial variables that could distinctively impact re-purchasing, we first identified customer value proposition as per the customer buying decision process. Next, core value propositions of choice efficiency and competitive price are defined to determine vendor satisfaction during the searching stage and purchasing stage. The trust level is also introduced in the sense of reflecting confirmation to guarantee after purchase security. Then, significant managerial variables to impact on core value propositions are extracted. The resulting structural model illustrated that search convenience and quality assurance affect the choice efficiency, and re-purchase intention is strongly explained by both the vendor satisfaction and trust level. The empirical testing results also support that transaction cost reduction is key determinant of shopping at the Internet shopping mall. Furthermore, trust level should be combined to induce re-purchasing in addition to transaction cost savings.

This article proposes a logic model for assessing the performance of the outcome of public research as a technology valuation method. It consists of two parts and eight steps. The first part is a scoring system and the second part is a validation process of the performance index derived from scoring by valuation method. The scoring in the first part generally requires a focus group method to find out the value drivers and make an evaluation table. The reason why we call it the technology valuation method is that the first part is derived from the simple evaluation of technology value using checklists for value drive. The second part is the regular technology valuation process. The model is designed for the measurement of unquantifiable outcome. Is knowledge or scientific outcome comparable to the measured outcome? If possible, how big is the unquantifiable outcome? This model is based on financial valuation techniques with clear or acceptable market data. Therefore, it cannot work solely for unquantifiable outcomes without comparable measurable outcomes, unlike economic valuation.

Competitiveness of a firm essentially depends on the value of the product or service the firm supply. Product or service of high value derives customer purchase activity. Service mix is the process which creates competitiveness by value creation for customers through optimal combination of physical characteristics of product and service. This research is to contribute competitiveness increase of Korean manufacture industry by study of the effect of service mix as to the business competitiveness. Usually competitiveness advantage approach relies on the industry structure competition theory and the resource-based approach. However, it is said that, while the industry structure competition theory helps finding attractive industry, it rarely helps finding which companies succeed or fail in the specific industry. The resource-based viewpoint approach is limited in that this cannot provide any theory or systematic frame for the analysis even though it has contributed a lot to the competitiveness increase. Power process approach is applied to this study in order to overcome this limit and to Increase the business competitiveness. Power process is the process to create the value, the source of power by interaction of power elements, value, needs, environment and relation, the five power determination elements. Power process is a process that creates value to satisfy the power objective for the attainment of the goals of the power subject. This study is to contribute for the manufacture industry by establishing service mix strategy from the power process viewpoint.

In response to changes in the global market environment, companies in the Information and Communications Technology (ICT) industry have begun to pursue cooperation and competition on a business ecosystem level. In particular, to become a leader in the new growth engine industry of Internet of Things (IoT), companies around the globe aim to consolidate vertically up the value chain through a solid establishment of their platforms. This paper looks at Samsung and Xiaomi, whose strategies for creating an ecosystem based on their own platforms differ in accordance to the ecosystem in which they compete. An analysis of these two companies indicate that Samsung pursues a strategy to become the market standard by openly sharing its platform with complementary companies, whereas Xiaomi pursues a strategy that achieves value as a channel owner through the restriction on which companies may become partners. This paper concludes that as Samsung and Xiaomi strive to become IoT industry leaders, each company pursues a variant of a platform-based value chain integration strategy based on the specific nature of the ecosystems in which they compete, thereby creating value through a symbiotic relationship with their partner companies.

This paper proposes how to design and implement data-driven strategies by investigating how a firm can increase its value using data science. Drawing on prior studies on architectural innovation, a behavioral theory of the firm, and the knowledge-based view of the firm as well as the analysis of field observations, the paper shows how data science is abused in dealing with meso-level data while it is underused in using macro-level and alternative data to accomplish machine-human teaming and risk management. The implications help us understand why some firms are better at drawing value from intangibles such as data, data-science capabilities, and routines and how to evaluate such capabilities.

The collaboration that seeks to complement each other by judging and sharing the comparative advantages between companies is currently being actively progressed as a new and unusual collaboration that is not routine among not only the same industry but also different industries. This trend is increasing consumer interest based on enjoyment and fun. However, these collaborations cannot consistently lead to positive effects, and rather, if all companies collaborate, it could have an adverse effect. The current study explored the consumer's response to the attitude toward product and purchase intention of collaboration through consumption value and brand trust based on the consumer's understanding, assuming that the consumer's response cannot always be positive. As a result, brand trust played a mediating role in the intention to purchase and attitude toward product. This study examines the relationship between consumption value and collaboration products between brands, and from the perspective of a company, it can provide practical implications for establishing brand management and strategy through a unique collaboration strategy based on the understanding of consumers.

Many physical systems are hybrid in the sense that they have continuous behaviors and discrete phenomena. In control system with multiple models, switching strategy and stability of the closed-loop system under switching are very important issues. In this paper, a novel adaptive control scheme based on multiple parameter models is proposed to cope with a change in Parameters. Switching strategy guarantees the non-increase in the global control Lyapunov function if the estimation of Lyapunov function value converges. Least-square estimation is used to find the estimated value of the Lyapunov function. Switching and adaptation law guarantees the stability of closed-loop system in the sense of Lyapunov. Simulation results on anti-lock brake system are shown to verify the effectiveness of the proposed controller in view of a large change in system parameters.

Most realistic control systems contain nonlinearities of some form. One nonlinearity commonly found in control systems is a saturating element. If integral control is applied to such a system to eliminate steady state error, an undesired side effect known as integrator windup may occur when lage setpoint changes are made. This effect leads to a characteristic step response with a large overshoot and a very high settling time. To avoid this situation, many different anti-windup strategies have been suggested. But existing strategies remain over shoot and high settling time. This paper proposes a new anti-windup strategy for PI speed controllers. When the speed control system is changed P controller to PI controller. Integrator has an appropriate initial value. This value results over shoot and high settling time. The SIMULINK/MATLAB-based comparative simulation results and experiment results of speed controller have shown its superior control performance to that of a proposed anti-windup speed controller.
