It is very important to support communications among operators in the emergency of large scale plants. This paper deals with a communication support system for emergent situations in a hierarchical management structure for large scale plants. Our system is based on the communication model which considers human related factors such as “competence”, “duty”, “responsibility” and “knowledge”. A prototype of a group communication support system is developed based on the model, and the system is evaluated for a plant example

An empirical study was performed to examine the role of individual-, contextual-, and social-level factors on the media choice of geographically distributed teleworkers. Relevant data were gathered from teleworkers of a company who were distributed throughout several satellite offices. Data analysis indicated that teleworkers choice of a medium resulted from the dynamics of individual-, contextual, and social-level variables. management support as a social influence showed the strongest impact on teleworkers media use. The study confirmed that, though regarded as a lean medium, email could become an effective and rich communication tool through an active social structural process.

The Defense Advanced Research Project Agency (DARPA), in conjunction with the U.S. Navy, initiated a research program for the design and construction of a distinctive warship for the 21st century known as the Arsenal Ship. By using an innovative development and acquisition approach it was hoped to streamline the procurement process and reduce costs. In an environment where budgets are being cut, both industry and Government were challenged to develop, design, and produce the innovative ship and related mission systems to meet specific performance capabilities within strict affordability constraints. A key element of this innovative acquisition approach was a new certification scheme designed to replace the traditional test and evaluation (T&E) and acceptance process. The purpose of this paper is to describe the development of the certification plan during Phase LI of the Arsenal Ship program by the American Bureau of Shipping and the contending Shipyard teams, and to discuss the potential benefits of this alternative certification approach. Although the Arsenal Ship program was canceled late in 1997, insight derived from the exploration of new certification concepts could benefit future design and building programs.

Location management for database migration in ATM networks

systems and Computers in Japan 1998年第9期28卷

作者： Takahiro Hara Kaname Harumoto Masahiko Tsukamoto Shojiro Nishio Department of Information Systems Engineering Graduate School of Engineering Osaka University Osaka Japan 565

Since in broadband networks the whole contents of a database can be transferred from one site to another in a short period, database migration is expected to be one of the most powerful database operations in future distributed database systems. In an environment with database migration, it is necessary to develop a method to manage the location of each database so as to allow accessing of migrating databases. In this paper, we first propose several database location management methods, some of which make use of the features of ATM (Asynchronous Transfer Mode) networks. Then, we compare the performance of these methods by simulation study for various system parameters, such as the frequency of queries and of database migration, and the scale of the network. The results are used to identify the optimal location management method for a given system environment. © 1997 Scripta Technica, Inc. Syst Comp Jpn, 28(9): 35–45, 1997

The historical analytical data collected at Murdock demonstrate that: Constitutent concentrations in ground water in the area of highest known contaminant concentrations and along the flow path downgradient of that area decreased over the 3.5-year period when we began monitoring at the site and when we conducted the biogeochemical study. The ground water plume has stabilized and will not move further south. Chlorinated hydrocarbon parent products (TCE and 1,1,1-TCA) are degrading to their daughter products (1,1-DCA, 1,1-DCE, and cis-1,2-DCE) and thence to VC. The estimated total mass of chlorinated hydrocarbons dissolved in ground water was reduced from 1032 to 346 pounds between 1993 and the end of 1996 (approximately 66%). However, the scoring from the AFCEE protocol showed that there was only 'limited' evidence of biological dechlorination occurring at the site.

“programmic filters”: A framework for the design of high-performance nonlinear filters for low-level picture processing

引用

systems and Computers in Japan 1998年第3期28卷

作者： Oichi Atoda Koichi Okano Masaki Tomisawa Hitoshi Tamura Graduate School of Bio-Applications and Systems Engineering Tokyo University of Agriculture and Technology Koganei Japan 184 Faculty of Engineering Tokyo University of Agriculture and Technology Koganei Japan 184 School of Management Science University of Tokyo Kuki Japan 346

Into the chaotic space of nonlinear spatial filters for low-level picture processing such as smoothing or textural feature extraction, we introduce a design framework in which a designer converts heuristics into filter functions, similarly to the activity of a computer programmer formulating program concepts in the framework of a programming language. First, to assure uniform gain and bias change, filters are constrained to respond in the same manner as their linear counterparts. Then it is shown that a “quasi-linear” filter is generated from successive application of several rules similar to a sentence from a parse tree. Filters so generated are called programmic filters. Some of the rules allow Boolean functions, which are suitable to heuristic thought. Thus, the set of those rules constitutes the filter design framework. Examples of high-performance programmic filters including an edge-preserving texture-reject filter are presented. © 1997 Scripta Technica, Inc. Syst Comp Jpn, 28(3): 71–81, 1997

Entity-relationship and object-oriented data modeling - An experimental comparison of design quality

引用

DATA & KNOWLEDGE engineering 1997年第3期21卷 297-315页

作者： Shoval, P Shiran, S Information Systems Program Department of Industrial Engineering and Management Ben-Gurion University of the Negev Beer-Sheva 84105 Israel

We compare EER and OO data models from the point of view of design quality. Quality is measured in terms of (a) correctness of the conceptual schemas being designed, (b) time to complete the design task, and (c) designers' preferences of the models. Result of an experimental comparison of the two models reveal that the EER model surpasses the OO model for designing unary and ternary relationships, it takes less time to design EER schemas, and the EER model is preferred by designers. We conclude that even if the objective is to implement an OO database schema, the recommended procedure is to: (1) create an EER conceptual scheme, (2) map it to an OO schema, and augment the target schema with behavioral constructs that are unique to the 00 approach.

Flexibility has become an important priority in the formulation and implementation of manufacturing strategies. This in turn has opened up a new class of design problems for such systems. Flexible assembly systems (FAS), consisting of a variety of processors and operations, provide the opportunity for improving product manufacturing flexibility, hence gaining competitive advantages. This paper considers a particular design decision problem for FAS. A matrix-based, polynomial-time lower bound algorithm is presented. Simulated annealing and tabu search metaheuristics are formulated to address the problems. Computational experience with these metaheuristics is reported.

Production flow control for a manufacturing system with flexible routings

引用

Production and Operations management 1997年第1期6卷 37-56页

作者： Krämer, Franz-Josef El Hafsi, Mohsen Bai, Sherman X. Department of Industrial and Systems Engineering University of Florida Gainesville Florida 32611 USA The A. Gary Anderson Graduate School of Management University of California Riverside CA 92521 USA Department of Industrial and Systems Engineering University of Florida 32611 USA

We study the dynamic routing problem for a flexible manufacturing system consisting of two unreliable machines and a finite buffer. One product-type is produced which requires two operations in sequence. The demand rate is assumed to be constant. Each machine is capable of performing both operations. The objective is to trace the demand while keeping the work-in-process low and the cycle-time short. An optimal control formulation is established for the dynamic routing problem. A production flow control algorithm is developed based on a combination of mathematical modeling and heuristics. The control policy is simulated and a comparison with the numerical optimal solution shows that it performs well for the instances under consideration.
