Purpose - This study examines a bundling effect on production and distribution in a patent-protected industry. Despite the heavy use of bundling strategies in the information and technology industry, literature has paid scant attention to bundling of intellectual property rights. This study examines a theoretical exploration of the bundling effect on licensing behavior. Research design, data, and methodology - To address this behavior, we build a simplified model consisting of three stages: 1) bundling decision, 2) licensing agreement, and 3) competition. The subgame perfect Nash equilibrium is applied to the model. Results - A single-patent holder with superior technology grants its own license to the multiple-patent firm, thereby leaving the market. Anticipating the single right holder's licensing strategy, the multiple-patent firm offers a bundle, making the single-right holder's bargaining position weaker. Conclusions - Bundling is an effective business strategy, resulting in multiple products for a firm as it faces other firms with single-product lines in each market. Taking advantage of the multi-patent or multi-product lines, the firm utilizes the bundling strategy obtaining better technology from the standalone single-patent firms.

Most of companies have analyzed markets continually and founded market strategies based on these analyses to gain competitive advantage. But sometimes some mistaken market analyses make the strategic decision-making of companies bring unexpected results. This because many companies just research or consider only the present condition, so they can't reflect dynamic change and the delayed feedback effect and then found the market strategy in the short-term angle rather than analyze the structural features of market on the whole. For that reason, this paper will describe how effective system thinking and system dynamics are as they found strategy of company for solving the problems and trying to find better alternative proposal by explaining process of founding market strategy with a casual loop diagram and a simulation model in the local government server market.

During the last decade many enterprises spent a huge amount of money for investment on Information Technology (IT) & Information System (IS) to attain competitive advantage and to maximize their business performance by satisfying the various requirements of customers. Under such circumstances, methodologies for evaluating IT impact on business performance are very important issues for strategic decision making on investment. In this study, we propose a performance evaluation model that adopts the concept of the Balanced Scorecard (BSC) and the Value Chain to analyze the financial impact and non-financial impact of IT & IS at each critical work area. This model combines the 4 evaluation areas from BSC and 6 critical work areas from Value Chain and measures the Key Performance Indicator (HPI) and the effect of KPI. Also, we present a case study of which the evaluation model has been conducted on a major manufacturing company. finally. we address some important notes to improve the IT & IS performances in the real-world.

In order to have competitive advantage for the business firms, companies need to raise competitiveness through the effective distribution and practical use of management resources along with strategic management of integration of existing management systems such as quality and business environment. Upon resulting of questionnaires to expert group, it is definite to have an integration of quality and environment system for the better efficiency of firms, and also recommended to have either a mixture of two systems or build up new integration system through uniform of two systems. The effects of the integrated system can be summarized as an increase of company image, efficiency of system operation, simplification of system management, synergy effects on the integration.

This paper deals with the energy saving problem of the follower aircraft in the loose leader-follower formation geometry in which the lateral separation between formation members is more than a wingspan of the leader aircraft. This formation geometry offers no drag benefit, but has a strategic advantage. In the case of loose formation flight, the follower aircraft usually consumes more energy than the leader aircraft because the follower aircraft should use more thrust to maintain given formation geometry, especially during the turning phase from the outside of the leader"s flight path or join-up phase. A formation control scheme based on the energy maneuverability is proposed in this paper. To design the proposed control law, the velocity command is designed using feedback linearization for the horizontal formation geometry and then coverts it to the altitude command using the energy equation. Numerical simulation is performed to verify the effectiveness of the proposed controller.

We investigate a systematic design procedure of automatic rule generation of fuzzy logic based controllers for highly nonlinear dynamic systems such as an engine dynamic modle. By "automatic rule generation" we mean autonomous clustering or collection of such meaningful transitional relations from one conditional subspace to another. During the design procedure, we also consider optimaly control strategies such as minimum squared error, near minimum time, minimum energy or combined performance critiera. Fuzzy feedback control systems designed by our method have the properties of closed-loop stability, robustness under parameter variabitions, and a certain degree of optimality. Most of all, the main advantage of the proposed approach is that reliability can be potentially increased even if a large grain of uncertainty is involved within the control system under consideration. A numerical example is shown in which we apply our strategic fuzzy controller dwsign to a highly nonlinear model of engine idling speed control.d control.

The marketing literature suggests that personal relationships between customers and service providers influence consumers' evaluation of goods and services. In this paper, we investigate the effects of service providers' conversation types (non-physical communication) on customers' evaluation and satisfaction in conversation with service providers. The empirical results show that the non-physical communication affect consumers' satisfaction in communication with service providers. This implies that the non-physical communication could be considered as a strategic tool when corporations need to differentiate their services from competitors to gain an advantage in competition.

We draw on well-established thinking in the complementary fields of organization theory and strategic management to develop a model explaining why fit among a firm's competitive strategy, its structure, and its technology is a prerequisite for superior performance. The contributions of this theoretical treatise are twofold. Firstly, it helps reduce the disconnect in thinking that exists between the strategy and organization-theory literatures on business-level issues. Secondly, it reveals the importance of managing the coalignment among strategy, structure, and technology which, in turn, forces recognition that competitive advantage does not exist in a static state but in a dynamic condition.

In modern business organization, the most important strategic factor in maintaining competitive advantage in business is to manage and utilize human resources effectively, which has eventually increased workload and psychological pressure in organizations. And research show that increased workload and psychological pressure has produced various tensions in business organizations, and it appears that those tensions have increased the workplace aggressive behavior among employees. In various types of aggressive behavior, this study focuses on verbal aggression. The study also attempts to find out the relationships among verbal aggression, job involvement, and turnover intention among administrative workers in colleges from May 20 to May 26, 2015. Summary of the research result is as follows. First of all, the study shows that verbal aggression directly increases the employee turnover intention.

We investigate a systematic design procedure of automated rule generation of fuzzy logic based controller for uncertain dynamic systems such as an engine dynamic model.“Automated Tuning”means autonomous clustering or collection of such meaningful transitional relations in the state-space. Optimal control strategies are included in the design procedures, such as minimum squared error, minimum time, minimum energy or combined performance criteria. Fuzzy feedback control systems designed by the cell-state transition method have the properties of closed-loop stability, robustness under parameter variabtions, and a certain degree of optimality. Most of all, the main advantage of the proposed approach is that reliability can be potentially increased even if a large grain of uncertainty is involved within the control system under consideration. A numerical example is shown in which we apply our strategic fuzzy controller design to a highly nonlinear model of engine idle speed contr l.
