Emerging 64 bitOSpsilas supply a huge amount of memory address space that is essential for new applications using very large data. It is expected that the memory in connected nodes can be used to store swapped pages efficiently, especially in a dedicated cluster which has a high-speed network such as 10 GbE and Infiniband. In this paper, we propose the distributed large memory system (DLM), which provides very large virtual memory by using remote memory distributed over the nodes in a cluster. The performance of DLM programs using remote memory is compared to ordinary programs using local memory. The results of STREAM, NPB and Himeno benchmarks show that the DLM achieves better performance than other remote paging schemes using a block swap device to access remote memory. In addition to performance, DLM offers the advantages of easy availability and high portability, because it is a user-level software without the need for special hardware. To obtain high performance, the DLM can tune its parameters independently from kernel swap parameters. We also found that DLMpsilas independence of kernel swapping provides more stable behavior.

System design, development and operational activities are monitored and evaluated to facilitate proper system security management in all phases of the system life-cycle. Effective system security metrics must address all phases of the system life-cycle as well as the associated organizational elements that interact during the system life-cycle to produce and operate the system of interest. A single system security metric, built from multiple components, is presented here as a fundamental system management security metric. This single technical security metric is used to support and evaluate the allocation of corporate and program resources, including time and budget. © 2008 The Authors.

DECi-hertz Interferometer Gravitational wave Observatory (DECIGO) is the planned Japanese space gravitational wave antenna, aiming to detect gravitational waves from astrophysically and cosmologically significant sources mainly between 0.1 Hz and 10 Hz and thus to open a new window for gravitational wave astronomy and for the universe. DECIGO will consist of three drag-free spacecraft, 1000 km apart from each other, whose relative displacements are measured by a differential Fabry-Perot interferometer. We plan to launch DECIGO in middle of 2020s, after sequence of two precursor satellite missions, DECIGO pathfinder and Pre-DECIGO, for technology demonstration required to realize DECIGO and hopefully for detection of gravitational waves from our galaxy or nearby galaxies. © 2009 IOP Publishing Ltd.

This paper provides a cost-benefit analysis for a real-time, autonomous inventory management system for the International Space Station (ISS) based upon Radio Frequency Identification (RFID) technology. This paper describes a Net Present Value (NPV) analysis of a possible application of the system to the International Space Station's cargo transfer bags. Quantities such as crew time, cargo launch volume, and cargo launch mass were monetized to allow comparison of costs and benefits, and several different implementation scenarios were evaluated. The analysis found that the application has marginal or negative value under conservative assumptions, but possibly significant positive value when inventory transactions are concentrated in a subset of the total cargo transfer bag population, and/or if ISS Operations are continued into 2018/2020. We show that a modest concentration of inventory transactions - for example, 75% of transactions occurring in the 50% of the bags that are RFID equipped - results in a positive mean NPV of approximately $46.8 million, and an 84% probability of a positive NPV. Also, a gradual Phase-In Implementation Scenario - as it is modeled in this work - is inferior to a more rapid deployment of the system via Modification Kits. Copyright © 2008 by Abraham T. Grindle.

Wang et al. [1] proposed a multiple-stream yield index S pk M . In addition to the point estimation, such as interval estimation are also important. In this paper we derived explicit forms of the cumulative distribution function and the probability density function of the estimated index S pk M . We developed a practical procedure and formula to provide practitioners an efficient tool for interval estimation on the yield index S pk M . An application example is illustrated. The procedure and formula are effective and easy to used, and should be expectant for in-plant applications.

Solving the resource-constrained project scheduling problem by genetic algorithm

引用

Journal of Japan Industrial management Association 2007年第6期57卷 520-529页

作者： Long, Luong Duc Ohsato, Ario Graduate School of Engineering Nagaoka University of Technology Japan Department of Management and Information Systems Science Nagaoka University of Technology Japan

The resource-constrained project scheduling problem (RCPSP) is one of the most difficult challenges in project schedule management. In the previous research work for RCPSP, activity durations in the project are often initially determined by the fixed values (fixed activity durations), and then the optimization process is carried out to assign the optimal start times of activities. In many cases, however, the activity durations vary within the certain ranges (variable activity durations), and depend on the scheduling objective. Thus, it is highly probable that these initially fixed activity durations lead to unexpected results. The way in which the activity durations are reasonably assigned is very important for reducing the overall project duration under resource constraints. For solving the RCPSP with variable activity durations, it is impossible to use the traditional methods (such as CPM, PERT), so the new method based on genetic algorithm (GA) is proposed in this paper for solving the problem. In the proposed method, the genetic algorithm is introduced to determine the optimal activity durations, and the heuristic rules are applied to assign the optimal start time of each activity so that the overall project duration under resource constraints is minimized.

Mixed-model assembly line is a type of a production line where a variety of product models with certain level of similarity in operational characteristics are assembled. Due to this variety, especially, work load variance cause several inconvenient phenomena such as low efficiency, line stops. To cope with these problems, hierarchical design procedure for line balancing and job sequencing is proposed which is structured in terms of amelioration procedure. On our Genetic Algorithm, a new encoding procedure entitled Priority-based Multi-Chromosome (PMC) is proposed, of which feature is a multi-functional chromosome and provides efficient representation of task assignment to workstations and job ordering. From lean production point of view, U-shape assembly line system has been recognized to offer several benefits over the traditional straight line system. To assure effectiveness of proposed procedure, both straight and U-shape assembly lines are examined under three major performance criteria, i.e. number of workstations (or line efficiency) as static criterion, variance of workload and distance between average and actual workload on the assembly line as dynamic criterion. The results of simulation experiments suggest that proposed procedure is effective management tool of mixed-model assembly line system.

Nowadays, Kaizen technologies are recognized widely over the world. However, it does not always guarantees success stories. One relevant way to realize effective Kaizen activity is to establish a system enabling transfer of this technology within/among organizations. Based on this standing point, we propose a) framework of such system and its functional features and b) way to realize transferability of Kaizen technologies under proposed system. For the first issue, there are three phases i.e. classification, reuse and new method development phases which handles typical Total Productive management (TPM) technologies such as Visual management (VM), POKAYOKE, KARAKURI. For the second issue, four-phase approach described below is proposed to cope with the problem. 1) Clarifying the keyword of current Kaizen problem, 2) Retrieving Kaizen method base by using established keyword in phase 1 to detect applicable Kaizen technologies, 3) Selecting suitable Kaizen technology to solve current problem effectively, 4) Solving current problem to apply suitable Kaizen technology derived in phase 3 The proposed framework in this paper is based on taxonomy of Kaizen technologies, which enhances mobility of Kaizen technologies (seeds) for getting effective solution of performance improvement projects (needs).
