This paper proposes a ubiquitous environment store, which is composed of cameras, sensors and displays, for supporting decision concerning commodities based on each customer’s shopping interest. This store suggests that three analyzing views can be utilized to analyse relations between customers’ interests and their behaviours towards commodities. This store collects data on the behaviour of each customer, who has agreed to be observed, and makes individual models, by analyzing collected data. This store also provides commodity information, which is decided by the individual’s model, to each customer through a display, which is in front of this customer. Comparing this system to a non-system through a purchase experiment of clothes shows this effectiveness of this system.

Whereas Business Process Management (BPM) systematically guides employee participation in business processes, there has been little support, use or development of user-friendly functions to improve the efficiency of those processes. To enhance business process efficiency, it is necessary to provide automatic rational task allocation and work-item importance prioritization, so that task performers no longer need to be concerned with process performance. In the context of BPM, two different perspectives, the Process Engine Perspective (PEP) and the Task Performer Perspective (TPP), are considered. Accordingly, we developed a comprehensive method that considers those two perspectives, in combination rather than separately. We carried out simulation experiments to show the combinational effect of the two phases.

The authors have developed a performance test, CPTOP (Cognitive Performance Test of Productivity), which combines 11 basic task testss to evaluate intelligent abilities of office workers in order to quantitatively and ob-jectively evaluate their productivity by controlling office environment. However, in the previous experiment, it was found that the results of CPTOP contain in-fluences of learning effect and variation of difficulties depending on each prob-lem set. In this study, therefore, subjective experiments have been conducted in order to compensate these influences and a correction method has been proposed.

This research has two objectives: first, to develop a method to quantitatively clarify the causal relationship between store improvements (store ) and store features that attract customers; second, to verify the effectiveness of the method developed. The results of this research confirm two points. (1) The causal relationship was quantitatively clarified through the use of a covariance structural analysis, and the degree of the relationship between the store features that attract customers and store kaizen could be understood. (2) The proposed methodology has proven to be useful in an actual store improvement activity. The owner of the store studied in the investigation commented, “It is very important to set up a hypothesis when seeking an improvement. This research provides a helpful framework for doing so.”

The written examination for job hunters in Japan is an important examination that cannot be skirted as the first step in the hunt for employment. However, there is no environment that can be studied using easy methods (mobile phones, etc.). In this research we clarify a methodology for constructing a prototype system for finding employment SPI measures. After constructing a prototype, we examine the effectiveness of the methodology. We use answer formats to achieve two purposes. (1) We clarified an answer format that can be efficiently studied through an experiment in ‘no space’ in order to produce a measure site that can be efficiently studied in little time. (2) We constructed a prototype for selecting answer formats in order to examine whether the prototype can be used to select the following two formats on a mobile phone: first, ”the word, the meaning of the word, and an example of the word in use”; second, ”the word, an explanation of the word, an example of the word in use, and the meaning of the word.” (3) The test-takers studied the constructed prototype on mobile phones, then our group examined the effectiveness of the prototype based on the questionnaire results. The results indicate that the form can be efficiently studied. Thus, we can conclude that the prototype constructed can be used to select the following two answer formats: ”the word, the meaning of the word, and an example of the word in use” and ”the word, an explanation of the word, an example of the word in use, and the meaning of the word”.

The AMPAC proposes a simple and unified format to describe parameters of the printing production process such as design, press and bookbinding. The database described by the format can be used commonly in any processes connected by the network production system, since the description accepts any parameters in any processes. A print production system assisted by computers should be very helpful to boot it after altering a parameter of the process, since preparation for starting up a printing machine requires abundant knowledge and wisdom. This paper gives details of the knowledge and wisdom stored in the AMPAC database used for booting the printing machine. Parameter data stored in the AMPAC database can easily be searched and found all of resetting targets in the printing machine when a parameter in the process is changed. This advantage comes from the fact that each parameter of the machine setting can be connected with the related parameters in this database.

The overall objective of this research project is the development and evaluation of a flexible and cooperative management system within SME based production networks for the ramp-up process. Inter-organizational processes of six previous ramp ups were analyzed and documented in flow charts. High-level executives and domain-experts of the production nets developed in moderated focus-groups standardized steps and phases of the ramp-up processes and agreed on one common reference workflow. The reference workflow is the basis for the further development of the inter-organizational management of virtual project teams supported by an IT-assisted workflow management system.

In this article, we examine individual spatial cognitive ability to improve the usefulness of a car navigation system. We developed a driver support system through which individuals can view an unfamiliar route before they actually drive the route. Using this system, we performed experiments to confirm the effectiveness of our approach, and we discuss the result of the experiment.

The object of this research is to build supporting systems for disaster victims, especially for the elderly. These systems are considering as follows: support the people who belong to the specific area, work on the initial stage of disasters. By using these systems, the people in the area can be easy to refuge and to communicate each other. Therefore we suggest several ideas to build systems. And we focus on the system which concerns the elder’s action to refuge and demands of the elderly in such situations. Then we aim at designing concrete functions based on these ideas.

Logistic integration is a essential condition for the development of maritime-port transportation. This paper proposes to demonstrate that this integration is dependant on a digital strategy. A conceptual architecture is proposed here. This architecture uses the emerging technology of web services as a good solution for enterprise application integration (EAI).
