Proposition and definition of specific method for R&D evaluation has being the major issue for public research institute in order to fulfill its responsibility toward sustainable development. However, the existing method of R&D evaluation is unable to structurally clarify the relationship between role of public research institute and preferential R&D from long term point of view. Therefore, this paper aims to propose new method of R&D evaluation for public research institute by planning gaming simulation of R&D experts, and validate the proposed method by trial experiment. The proposed method turns out that it can successfully clarify the relationship between role of public research institute and preferential R&D by trial experiment.

We propose a method to quantify costs of an information security incident in Japanese national university corporation. In order to execute several corrective and preventive actions within a limited budget, we need some indicators to compare the level of urgency or importance on each action. The total amount of loss shall consist of not only the loss directly caused by the incident such as broken equipments and lost profits, but also the indirect cost to recover to the original state. We can calculate those indirect costs with the proposed method by defining the data item corresponding to the cost factor. We applied the proposed method to constructing ISMS in Yamaguchi University, and confirmed the effectiveness.

The manifold information securities measure is necessary by the spread of Internet in the society.We propose about the method for presumption of information security incident in the enterprise.
The method can presume that incident occurs by the importance and the attribute of IT assets.The attribute converts the warning log data that occurred and estimates the similar incident that does not occur. The information security measure in ISMS(Information Security Management System) is made for the incident presumed high incidence in future by the method.

Many academic people and practitioners point out that it is hard to be supported by scenario analysis methods about actual problem situations, because the identification of an agent's decision making model representing plausible behaviors is very difficult The primary purpose of this paper is to propose a method of model building for making scenario analysis methods effective options. This proposed method starts from minimum model elements, and examines whether an additional element should be introduced in terms of plausible behaviors. We give a case study of introducing visitor's preference in the theme park problem. The result of this case study suggests that the visitor's preference has a strong relationship to the phenomena which could be observed at an actual theme park.

Coalition formation situations are formally expressed as games in characteristic function form. Relations are used to compare coalition influence. Three relations are proposed in this presentation. First relation compares coalitions with respect to how much they can make other coalitions not produce profit. Second relation compares coalitions with respect to how much they can reserve thir profit against deviation of members. Third relation compares with respect to how much the coalition can increase profit by cooperation. Some properties which the proposed relations satisfy are given.

In general, obtaining the conceptual model in the real world becomes difficult as the range of object domain grows. In that case, the object is divided into some overlapping parts, and conceptual model is obtained by integrating models of each part. Or, the object is recognized at a higher abstraction level, and conceptual model is gradually improving. In this paper, we consider formal semantics of ER diagrams (ERD) in order to explore its possibility for the integration modeling approach.

An effective IT investment will be one of the key factors for an organization to remain competitive in the global market.
Although many Japanese organizations have the ability to develop high quality software, it appears that they have difficulty using IT investments to improve their organizational effectiveness.
To discuss the improvement of their return on investment in software development, data from some real cases have been analyzed and discussed, in order to identify the factors for success and failure of software development.

I categorized the clusters to modular cluster based on the division of labor, and integral cluster based on knowledge creation integrating tacit knowledge. The higher a degree of modular business architecture is, the higher the local firm ratio is because of the division of labor as module. The higher a degree of integral business architecture is, the lower the local firm ratio is because many strategic partners enter into the cluster at the same time.

Balanced Score Card (BSC) is proposed as a method to translate an organization strategy into Key Performance Indicators (KPIs). How many KPIs are required for each perspective is an important research issue. It is hard to design appropriate KPIs to satisfy the required perspectives. Agent-based simulation can be an effective tool for managers' decision support about the KPIs design. In this paper, we clarify requirements for agent-based modeling for the design of KPIs. The requirements consist of defining the type and the characteristics of an organization, specifying assumptions, designing the parameters, and analyzing scenarios. The simulation satisfying the requirements can analyze effects of how KPIs are weighted in an organization under strategic questions.

Precedent studies have been proposed several methods to quality function deployment analysis by using
user comments and evaluation in web sites. There is room to develop these methodologies to get
information about evaluation points of the user satisfaction. This paper proposes a new method to
calculate the importance degree of demand qualities by using text mining techniques. We make a
figure of the demand quality structure by analysis of user reviews on the evaluation Web sites for the
mobile telephone market as an example. From the result of analysis, we give consideration about the
effectiveness of our proposal

It is important for manufacturers to keep right inventory level of items for successful operation. Accurate demand forecasting is required for planning production schedules to keep right inventory level. Since it is difficult to apply statistical demand forecasting methods to new items just after the launch, diffusion models approach is used and it does work well in such a case. However, this approach does not have acceptable forecasting performance if new items have a past record of sales before launch date such as pre-order and initial sales. We will propose modified diffusion models with time lag and bias effects to forecast demand for such new items accurately. The result of forecasting performance evaluation shows that the proposed models are superior to traditional diffusion models.
