IC Tags is expected as new tools for SRM (Supply Chain Management), CRM (Customer Relationship Management), Inventory Management, and as a new platform which needs collaboration crossing companies and company internal organizations. This paper analyzes collaboration strategy in IC Tag business. As the standpoint of the analysis, I selected the "mass customization". The reason is because the IC Tag provider must not only satisfy customer by services but also solve increasing cost by any collaboration.

This paper proposes (1) 3 types of business models, (2) detailed collaboration, (3) comparison between Japanese and US institutions, and (4) issues.

I will continue to follow this survey checking IC business more widely and deeply. My goal is to feedback my research to real Enterprise.

In this paper, we report how some characteristics of a cosmetic products evaluation site users depend on two parameters, length of subscription period and number of purchase times based on evaluative information on the site. The study is done through a correlation analysis of a survey result from the users of an evaluation site on cosmetic products. As a consequence, between long-period subscriber and short-period subscriber. few differences are shown on their recognition of effectiveness on information sources and purchasing behavior. Another side, their recognition of effectiveness on information sources and purchasing behavior clearly depend on the number of purchase times based on evaluative information on the site- The users, who purchase cosmetics more than four times in the belief of the evaluative information on the site, recognize evaluation sites are more effective as an information source both absolutely and relatively, and buy cosmetics more prudently than other users.

Hatch, the mutual reference system is a kind of decision support system which targets ill-defined problem of multi-goal combination problem under the situation where the knowledge is not well maintained. It supports both of the problem comprehension and the problem solving. The support of the problem comprehension consists of the knowledge maintenance, decision of goal and the comprehension of the situation where the user is involved. For that purpose, Hatch promotes the user to understand the elements of the situation, solution and goal. Also, Hatch affiliates user to grasp the causal relationship between those elements.

In this paper, a component development method is proposed for developing a business logic layer of application software. This method consists of a common architecture (PSER), basic components and a builder tool. PSER separates a business logic layer into four sub-layers; Process layer, Service layer, Entity layer and Rule layer. Then a guideline for how to extract components in a business logic layer is proposed, i.e. extracting components independently in each sub-layer. The process in each component is implemented by connecting basic components, and its connecting work can be executed visually on the builder tool. In the latter part of this paper, a case study of applying this method is shown. Especially from the perspectives of reusability of components and maintainability of application software, this method is substantiated to be effective. For example, in the case study, reuse rates of 61% and 55% in Process Layer and Service layer respectively have been achieved.

In evaluation of complex systems, evaluators' preferences in design decisions become often inconsistent or incomplete. Preference relation of evaluators may not satisfy the transitivity property of ordered sets. Different evaluators will use different sets of attributes for design evaluations, depending on his point of view. We take account of rather a family of attributes sets, and represent all choices including potentially inconsistent preference relation. One of the main purposes of this paper is to present a methodology for representing inconsistent preferences of evaluators. In this paper, we focus on the problems of inconsistent preference relation. We assume that we have prepared evaluation attributes. One of our main objectives of this paper is to select important evaluation attributes and construct minimal evaluation structure under the assumption. For the case that the preference relation is not representable by prepared evaluation attributes, we give the way to construct new additional attributes based on the prepared evaluation attributes. Based on the proposed methodology we propose grid evaluation structure approach for the real questionnaire survey.
