    　View Summary

    For many years, supply performance of goods to demand sites has been analysed, designed and improved by various ways such as Heijunka concept and methodology. Basic structure of this approach is, in general, to adapt demand speed and fluctuation by managing work-in-progress. This research, taking electricity supply operations on the smart-grid platform as the objective system, examines its performance for identifying the way to stable supply. Performance analysis is examined by simulation experiments with the proposed model and obtained results suggest that Heijunka of power supply is realised in time-domain by storage batteries.

    　View Summary

    Compositional dependency of all-optical light helicity-dependent magnetic switching (AO-HDS) in ferromagnetic GdFeCo alloy is presented. It is found that AO-HDS is associated with the collinear sub-lattice magnetization and not with the net magnetization. An explanation of the AO-HDS based on magnetic circular dichroism exactly matches the above features of experiments.

    　View Summary

    Conventional pure magnetic recording schemes have a serious and unavoidable problem known as the ferromagnetic resonance (FMR) limit. Here we demonstrate a fast precessional switching via interplay of ultrafast heating by ultrashort pulse laser and large temperature dependency of magnetic resonance. In ferrimagnetic GdFeCo, when the temperature approaches the angular momentum compensation point T-A, both frequency of FMR mode and the Gilbert damping parameter increase significantly. High-speed and strongly damped precessional switching was triggered with ultrafast heating of a Gd24.5Fe66.1Co9.4 across its magnetization compensation point T-M up to T-A, under a static applied magnetic field. To initiate and investigate the magnetization reversal, we have used an all-optical pump-probe technique employing an amplified Ti: sapphire laser system with 90 fs pulses. In particular, following the laser excitation with low pump fluence (0.9 mJ/cm(2)) the magnetic system relaxes back toward initial state while the rather high pump fluence (3.3 mJ/cm(2)) excitation induces a metastable opposite magnetic state. After the sudden heating which causes just 30% reduction of magnetization at first breakdown, consequently magnetization was started to rotate across M-z = 0 within 6 ps during first precession and finished the high damped precessional motion within few cycles into opposite direction.

    地球温暖化や化石燃料枯渇の対策として、太陽光発電をはじめとした再生可能エネルギーの普及が求められているが、その発電量は天候などの自然環境に依存するため、蓄電設備の充放電による供給力の平準化が必要となる。一方、各国で無排出ガス車規制の導入が行われつつあり、内燃機関を動力とする従来型の自動車から電気自動車（EV）等へのシフトが急速に進むと考えられる。EVの充電は、車両を利用しないときに、走行に必要な分を上回るだけ行う必要があるが、急速充電設備や電力需要の平準化などの制約を考慮する必要がある。本研究では、不確実性を有するこれらの各課題について、モデルの構築と解法の検討を行った。

  • サプライチェーン構築・改善技術高度化のための多段階・多目的確率計画モデルの開発とその解法に関する研究

    2021  

    　View Summary

    近年、ライフスタイルの多様化や電子商取引の急速な普及により、物流業界で取り扱われる荷物量は大幅に増加しているが、一方でその配達を担うトラックドライバーは減少の一途を辿っており、配送遅延の多発や収益性の低下といった深刻な問題が生じている。これら課題を解決するためにはサプライチェーンの改善・効率化が要求されるが、現実の問題では一般に、各段階においてそれぞれ異なる目標が設定された多段階・多目的最適化問題となるのみならず、不確定要素を含むことから、そのままモデル化し数理的に最適解を得ることは困難である。本研究では、不確実性を伴う多段階・多目的最適化問題について、モデル化と解法の検討を行った。

  • サプライチェーン構築・改善技術高度化のための多段階・多目的最適化モデル開発とその解法に関する研究

    2020  

    　View Summary

    近年の物流業界では、トラックドライバー不足や通信販売の利用拡大による取扱荷物量増加から、収益低下や配送遅延の発生など多くの問題が生じており、危惧される物流の破綻を防ぐためのシステム構築・手法提案が強く求められている。一方で、物流以外の各種産業においても、サプライチェーンの構築と改善は重要な課題である。これら問題は多段階最適化問題となるだけでなく、各段階においてそれぞれ異なる目標設定がなされることも多いため、現実の規模における問題をそのまま数理モデルに落とし込み、解くことは困難である。本研究では、これら多段階・多目的最適化問題を広く対象とし、モデル化とその効率的解法について検討を行った。

  • 再生可能エネルギーを含む電力サプライチェーンの負荷平準化モデル開発に関する研究

    2020  

    　View Summary

    地球温暖化や化石燃料枯渇への対策として、太陽光発電をはじめとした再生可能エネルギーの普及への要求が高まっている。しかし、これらの出力は自然環境に依存するために不安定であり、供給量の制御が困難である。そのため、発電・蓄電技術の低コスト・高効率・大容量化と並び、蓄電設備を利用した出力安定化のための充放電計画・管理モデルを開発することが重要である。本研究では、太陽光発電の不安定さを補うため、外部からの供給量を平準化するモデルを提案し、実数値遺伝的アルゴリズム (Real-Coded Genetic Algorithm, RCGA) による実装を行った。そして、シミュレーション実験によって、提案モデルの導入による効果を示した。

  • 再生可能エネルギーを含む電力サプライチェーンの管理技術高度化に関する研究

    2019  

    　View Summary

    地球温暖化や化石燃料枯渇の対策として、太陽光発電などに代表される再生可能エネルギーの普及拡大が求められている。しかし、その出力は天候などの自然環境に依存するために不安定という問題がある。そのため、発電・蓄電技術の低コスト・高効率・大容量化と並び、蓄電設備の適切な充放電計画・管理モデルを構築することによる出力安定化が不可欠である。 本研究では、太陽光発電を分散電源としたマイクログリッドを対象とし、グリッド外からの電力供給量 (系統負荷) の平準化、すなわち当該電力使用量の変動と平均値の削減を志向した蓄電設備の充放電計画・管理モデルを提案し、数値実験による性能評価を行った。

    　View Summary

    近年の物流業界では、トラックドライバーの不足に起因した労働環境の悪化が深刻な問題となっており、危惧される物流の破綻を防ぐためのシステム構築・手法提案が強く求められている。一方で、各種他産業においてもサプライチェーンの構築と改善は重要な課題となっている。本研究ではまず生産物流業界を対象に、生産スケジューリング・配送計画・在庫管理の各段階について確率計画法及び遺伝的アルゴリズムを用いた手法により効率化・全体最適化を図るためのシステム・手法の提案を行った。そして、他産業への技術移転の例として電力供給サプライチェーンを対象とし、確率計画モデルとしてモデル化し、数値実験を行った。
