In business or manufacturing process, various kinds of data, materials, and drawings are sent and received among individuals, facilities and organizations. Those can be regarded as the embodiments of collaborative relationship and specified by Synthetic Binding Method (SBM). In SBM, such relationships are captured to be represented as scenario of IDEF3 (Process Description Capture), which is easy for use of domain experts because its representation is intuitive.

In this paper, an evaluation measure for the scenario in IDEF3 is proposed. This measure focuses the collaborative object obtained by SBM and enables to capture and evaluate the scenario of the business or manufacturing processes.

In the field of international telecommunications where competitive principles are being rapidly introduced, alliance strategies are positioned as crucial factors in achieving competitiveness in the marketplace. The alliance activities in the recent years are very dynamic, causing significant changes in the market share held by the incumbents and new entrants.

The economic value of the alliance is recognized. To generate, maintain, and enhance the values of alliance, there are number of requirements that need to be addressed due to the diversity of international telecommunications business. In the discussion of market dynamics and regulatory policy, the issue is to clarify the framework of mechanism that illustrates the relationship between the economic value and the market share dynamics.

This paper discusses the major economic values that result from the alliance activities in the international telecommunications business. Furthermore, it discusses the factors inherent to the international telecommunications business that maintain and enhance the economic values resulting from alliance activities. It also describes the circulatory complementary relationship among variables which are multiple economic values resulting from alliances, service diversity, and supply and demand utilities that influence the variance of subscriber quantity. This circulatory complementary relationship will be shown as the framework of mechanisms that significantly impact the dynamics of international telecommunications market share.

This paper presents two things, design of a menu system generator and its implementation in a system theoretic approach. First, we specify functions of a menu system for task manipulation (model integration approach) and define a menu statement description language (MSDL) for it and introduce a concept of task execution flow diagram (TEFD), show that the MSDL is powerful enough to describe any kind of TEFD. Second, we formulize a menu system generator (MSG), which can address the above mentioned menu system, as a push down automaton, and implement the MSG to demonstrate that a information system specified in the theoretic way has a direct implementation in extProlog.

Today agile management can be realized given all of the following three kinds of quickness: a) quick recognition of an environmental change, b) quick decision-making on the countermeasures against the change, and c) quick implementation of the countermeasure chosen to cope with the change. In the recent business world the quickness of a) concerns information that an MIS deals with, the quickness of b) concerns use of the MIS for decision-making, and the quickness of c) concerns change of the MIS itself.

With a focus on c) above and assuming that flexibility is the core characteristic that an MIS should acquire to realize agile management, our study aims to clarify how MIS flexibility should be enhanced. With this aim in mind, we will survey the sources and types of MIS change demands, and we will consider in a structured way the characteristics that an MIS should have, such that they will conduce to its flexibility in dealing with these change demands. Having laid the groundwork mentioned so far, we will discuss practical methods to enhance MIS flexibility, and end by presenting our evaluation procedure for MIS flexibility.

The purpose of this thesis is how IT(Information Technology) can arrange decision making process in public administrative organizations more rational, based upon the comparison of public administrative organizations with private company. More concretely speaking, this thesis analyzes how IT can make decision making more rational at the level of both top leader and co-workers. In addition to that, on the proposition that the decision making process of public administrative organizations would be more rational, if they try to listen to the demand of people, this thesis analyzes how IT can contribute to absorb the demand of people.

The conclusion of this thesis is that IT can make the decision making process of public administrative organizations more rational by the useful use of IT. On the other hand, this thesis also concludes that even though they use IT in decision making process very well, the decision making process would not be rational, if they could not absorb people’s opinion in decision making process and in addition to that, public administrative organizations should recognize it costs to absorb people’s opinion.
