Integrated construction process management system
Masayuki Takata; Eiji Arai; Junichi Yagi
Mechatronics for Safety, Security and Dependability in a New Era, Elsevier Ltd, 271-276, 2006, Peer-reviwed, This chapter describes an implementation of an integrated construction process management system that includes both manufacturing process management features for building parts and construction progress management features at construction site. To monitor the flow of the building parts, Radio-frequency identifications (RFIDs) are stuck to all of the parts to be managed, and several checkpoints that are named as "gates", and are introduced within the coherent process through part-manufacturing plant line, logistic processes, and building construction processes. The system enables efficient project management and diminishes the loss in the construction by providing all information of both material manufacturing and building construction to all of material designing, material manufacturing, building designing, and building construction sites. © 2006 Elsevier Ltd.

M Matsuda; E Arai; N Nakano; H Wakai; H Takeda; M Takata; H Sasaki
KNOWLEDGE AND SKILL CHAINS IN ENGINEERING AND MANUFACTURING, SPRINGER, 168, 75-84, 2005, Peer-reviwed, ISO/TC184/SC5/WG4 is working on ISO16100: Manufacturing software capability profiling for interoperability. This paper reports on a manufacturing software interoperability framework and a capability profiling methodology which were proposed and developed through this international standardization activity. Within the context of manufacturing application, a manufacturing software unit is considered to be capable of performing a specific set of function defined by a manufacturing software system architecture. A manufacturing software interoperability framework consists of a set of elements and rules for describing the capability of software units to support the requirements of a manufacturing application. The capability profiling methodology makes use of the domain-specific attributes and methods associated with each specific software unit to describe capability profiles in terms of unit name, manufacturing functions, and other needed class properties. In this methodology, manufacturing software requirements are expressed in terns of software unit capability profiles.

M Takata; E Arai
KNOWLEDGE AND SKILL CHAINS IN ENGINEERING AND MANUFACTURING, SPRINGER, 168, 261-268, 2005, Peer-reviwed, This paper describes a system named "Glue Logic", which is a infrastructural system designed for factory automation control system, and a sample implementation of a layer structured control system architecture, which is named "Scalable Intelligent Control Architecture" reported in the DIISM2000. The "Glue Logic" supports the real-time controlling and monitoring system, by means of realizing communication and synchronizing among multiple agents. Using the active database technique, this system includes event notification message sending and condition monitoring features to eliminate data polling. This system also supports efficient programming environment, by increasing modularity and reusability of the software assets. Using the Glue Logic, we are now designing a real-time data gathering system in practical manufacturing lines according to the Scalable Intelligent Control Architecture, which permits expansion of control systems not only in spatial dimension but also in intelligence.

Human oriented production system architecture
Eiji Arai; Hidefumi Wakamatsu; Masayuki Takata; Keiichi Shirase
International Journal of Human Resources Development and Management, 1, 1, 90-98, 2000, Today’s factories have been aiming to fully automate production processes
however, the number of factories depending primarily on manual work will also be increasing. Therefore, it is necessary to develop management methods which both effectively use production facilities and provide job satisfaction for workers. This paper introduces the management structure for human-oriented production systems and explains how to assign jobs in such systems. The proposed structure includes two technologies: a factory communication network using the active database system and a dynamic scheduling method to guarantee the workers’ satisfaction. The active database system is used to gather real-time information on the floor and deliver ongoing schedules to workers in order to collect their response for dynamic scheduling. © 2000 Inderscience Enterprises Ltd.

M Takata; E Arai
INFORMATION INFRASTRUCTURE SYSTEMS FOR MANUFACTURING, CHAPMAN & HALL, 181-192, 1997, Peer-reviwed, In this paper, a infrastructural system designed for the factory automation applications, named ''Glue Logic'', is described. The Glue Logic provides an environment which supports tile programming, controlling and monitoring the manufacturing system, mainly in she levels of manufacturing work-cells. And this environment also supports efficient manufacturing programming, by means of high program modularity and reusability.
Using the service of tile Glue Logic, users can easily implement data-sharing; and task-interlocking among multiple application processes developed and compiled separately. Furthermore, this system includes event notification message sending and condition monitoring features to eliminate needs of data polling by means of active database technique.
As the result of the use of the Glue Logic, the application system can be build as a collection of the agents working together, and tile Glue Logic itself acts as it message exchange and shared data space manager.

YURA Kenji; ISHIKAWA Haruo; TAKATA Masayuki; MORISHIGE Koichi; ISHII Masahiro; YAMADA Tetsuo
Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, The University of Electro-Communications, Grant-in-Aid for Scientific Research (B), The study is concerned with the e^3-PLM (Product Lifecycle Management). The e^3-PLM is a kind of PLMs, and it is an "ecology-oriented", "enduser-oriented", and "electronic ICT (Information Communication Technology) based system. In the PLM the importance of end-users is insisted and product use history data are utilized to realize environment friendly product management. The obtained results are follows. (1) The structure of e^3-database for the PLM is designed. The database consists of a global database and local databases. The global database contains product design information, product handling information, product use history, and communication information, and it can be accessed by manufacturer, end-users, and recyclers. On the other hand, the local database is maintained by each sector and it contains internal information of the sector such as facility information, process plans, sales plans, etc. (2) For the important scenes in product lifecycle, the value of information in e^3-database is evaluated and the methods to utilize the information are developed. (a) The framework of PLM is developed and products management policies for products maintenance, renewal, and replacement are analyzed. Especially, environmental impacts related with products refurbishment are analyzed in detail. (b) A database structure is developed to utilize product use history data. Then, an algorithm is developed to determine the effective handling method of post-consumer products. (c) Processing and environment related attributes are added to products 3D-CAD models, and a design system is developed so that the environmental impacts of product over its lifecycle can be reduced at the product design stage. (d) Operation planning is a vital activity in manufacturing, remanufacturing, and recycling operations. Then, an operation planning support system using the standardized machining information is developed. (e) A method to calculate the economic value of the information in e^3-database is developed. Further investment decision problem with emissions trading is analyzed., 17310095

Study of make FMS control software systems highly re-usable and intelligent
TAKATA Masayuki
Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, University of Electro-Communications, Grant-in-Aid for Scientific Research (C), The aims of this research study were developing the software environment for FA (Factory Automation) integrating manufacturing cells, developing the FA software programming paradigm for distributed and collaborative manufacturing systems which makes those systems intelligent and highly-functioned, and also enhancing productivity and maintenance-ability of highly value-added FA software systems such as production management and equipment control. For these aims, I have developed an infrastructure system for FA control and named it "Glue Logic". This system manages the information on the provider and the consumer of each information at one place, and construct dependency relations among multiple agents dynamically at run-time. These relations illustrates flow of control, which is implemented by chaining information dependency, and the Glue Logic system provides each agents the notification messages which inform the change of the value of declared interested information. Using this infrastructure, I have proposed a method to program effective and reusable agents and a simple way for the implementation of message transaction among component agents, and also I have been evaluating feasibility of real-time intelligent control systems. In the first year, I developed prototype of work-cell control computers, also developed the "Glue Logic" software system including server program and some general purpose application agents, and opened my basic idea and program source codes via the Internet. In the next year, I developed some application programs, such as process scheduling problems and other combination optimising problems. These problem solvers are consisting of multiple agents work together, and search the tree-structured state space for answers with acceptable cost-performance ratio using heuristic knowledges. Through this development process, I evaluated requirements gathered by hearing from explicit and implicit users, I decided further research and development items., 09650130
