The roadmap-based planning is a path planning method which is used widely for a goal-directed movement in Robotics and has been applied to the world of computer animation such as computer games. However it is unnatural for computer characters to follow the path planned by the roadmap method as it is performed in Robotics. Flocking which is used for realistic and natural movements in computer animation enables character's movement by using a few simple rules without planning unlike the roadmap method. However it is impossible to achieve a goal-directed movement with flocking only because it does not keep states. In this paper we propose a simulation method which combines planning based on the road map with reactive actions for natural movements along the path planned. We define and implement steering behaviors for a leader which are needed to follow the trajectory naturally by analysing characteristics of roadmap-based paths and for the rest of members which follow the leader in various manners by detecting obstacles. The simulations are performed and demonstrated by using the implemented steering behaviors on every possible combination of roadmap-based path planning methods and models of configuration spaces. We also show that the detection of obstacle-collisions can be done effectively because paths are planned in the configuration space in which a moving object is reduced to a point.

Technology roadmap is a powerful tool that considers relationships of technology, product and market and referred as a supporting technology strategy and planning. There are numerous studies that have attempted to develop technology roadmap and case studies on specific technology areas. However, a number of studies have been dependant on brainstorming and discussion of expert group, delphi technique as qualitative analysis rather than systemic and quantitative analysis. To overcome the limitation, patent analysis considered as quite quantitative analysis is employed in this paper. Therefore, this paper proposes new technology roadmapping based on patent citation network considering technology life cycle and suggests planning for undeveloped technology but considered as promising. At first, patent data and citation information are collected and patent citation network is developed on the basis of collected patent information. Secondly, we investigate a stage of technology in the life cycle by considering patent application year and the technology life cycle, and duration of technology development is estimated. In addition, subsequent technologies are grouped as nodes of a super-level technology to show the evolution of the technology for the period. Finally, a technology roadmap is drawn by linking these technology nodes in a technology layer and estimating the duration of development time. Based on technology roadmap, technology planning is conducted to identify undeveloped technology through text mining and this paper suggests characteristics of technology that needs to be developed in the future. In order to illustrate the process of the proposed approach, technology for hydrogen storage is selected in this paper.

This study proposes a stepwise approach to product safety management(PSM), of which roadmap consists of five phases. ISO 9001 QM model is assumed as the first-phase model and each higher-phase model is built by adding a corresponding module to the lower one. In the phase order, those modules are CCMS, a failure to warn, manufacturing defect and design defect. The progress in PSM of a domestic food company is discussed.

Recently, the area of ubiquitous computing has gained a great attention both in academics and in industry. However previous research on this area attempts the categorization in part of context and the critical success factors (CSFs) and services ubiquitous computing unsuccesfully. The purpose of this paper is to propose a framework on ubiquitous computing, including its context, roadmap, CSFs, and services.

Among many logistics technologies, primary area should be investigated in terms of long term periods. Therefore private company and public sector can visualize approaches to their corresponding industry. In this paper, we introduce vision and roadmap for integrated logistics systems based on national technology as well as three technology areas and fifteen core elements.

With the advent of smart age, the competitiveness among companies and countries to preoccupy the advanced ICT technologies which lead the economic growth in the future have increased more than ever before. So have global standard competitiveness done under the situation of using international standardization as practical strategy for dominating market. It is essential to make standardization strategy and do systematic implementation for core technology which leads global market in order to fit such an environment and introduce smart society as soon as possible. Therefore, this paper suggests systematic approach and framework to make standardization roadmap in relation to R&D through analysing the current technology roadmap framework and standardization roadmap case and provides infrastructure to promote international standardization of domestic technology.

Construction Project Information System, which has promoted to improve the system during the past five years, is recently required to revise the new Roadmap of this system based on the rapidly changing construction industry's environment. For this reason, the present study was investigated the present condition of construction information, drawn CSF using SWOT method, presented the project direction, strategy, the priority plan, the specific task, and WBS by taskes. This Roadmap may be used to a basis data in measuring the result of construction informatization, and presented to the progress direction of information system in construction field.
