  1. All - optical networks employing the concept of wdm and wavelength routing are considered as the transport networks for the future. with the development of oxc and oadm, the optical transmission network based on wdm is not confined to point - to - point transmission. so, there must be the assignment and optimization of network resource on demand

    隨著oxc （ opticalcrossconnect ，光交叉連接設備） 、 oadm （ opticaladd / dropmultiplexer ，光分插復用設備）技術的不斷成熟，基於wdm （ wavelengthdivisionmultiplexing ）技術的光傳送網已不再局限於點對點傳輸，而是組網運用。
  2. Next, a novel priority - based wavelength assignment algorithm in all - optical networks with partial wavelength conversion is proposed, based on link independent assumption and the method of calculating the network the blocks probability. it improves the routing and wavelength assignment presented by others. this algorithm fits the demand of different business for asking the grade of corresponding different services in the modern all - optical network than the original algorithm

    其次研究了部分波長可變wdm網中支持優先級的波長分配問題，以及在此網路中網路阻塞概率的計算;基於鏈路波長佔用獨立性假設，改進了在部分波長轉換wdm網中已有的rwa演算法，提出了一種支持優先級的動態波長分配演算法，該演算法保證了較高優先級的光路建立請求具有較低的阻塞率，比原有演算法更加適合現代光網路中不同業務請求對應不同服務等級的要求。
  3. This kind of requirement assignment of computation can virtually ease the demand of hardware both in quantity and complexity. therefore designing an artificial model based on biological mechanism is an effective approach

    因此，模仿生物視覺系統建立相應的計算模型成為解決機器視覺中存在的諸多難題的一個有效手段。
  4. In terms of analysis of collaboration planning process among multi - project, ecnp - based coordination model and coordination process model for collaboration production planning are proposed to combine the controlled coordination with the free coordination for meeting the demand of multi - project production. ecnp based coordination mechanism is developed. through bidding mechanism and coordination between task manager and bidder, an assigning method based multi - agent coordination is proposed for assigning tasks in multi - project environments. task assignment problem model 、 bidding coordination mechanism and coordination algorithm are studied. external collaboration planning model is developed and adopt genetic algorithm to solve optimization of external collaboration planning

    分析多型號之間的協作規劃過程，提出多型號協作規劃的協調模型和協調過程模型，將主控協調和自主協調有效地結合起來，滿足了多型號並存生產的要求;建立基於ecnp的協調機制;提出基於多agent協調的多型號任務分配方法，採用招/投標的形式，通過任務的管理者與執行者之間的協調實現多型號任務分配，並對任務分配問題模型、招/投標協調策略及協調演算法等展開探討和研究，給出了在多型號並存環境下，在信息不完全的條件下進行任務分配的有效方法;建立了外部協作計劃模型，並運用遺傳演算法優化外部協作計劃的生成。
  5. Rcbac model introduces the context information and the group mechanism to the access control policies. in rcbac, the context information is used to control the user assignment and permission assignment dynamically and the group mechanism is used to simplify authorization further. thus, rcbac can implement the fine - grained access control and satisfy the enterprise ’ s demand for the unified resource access control

    在對rbac的一些改進模型分析研究的基礎之上提出了基於角色和上下文的訪問控制模型（ roleandcontext - basedaccesscontrol ， rcbac ） ， rcbac模型將上下文信息和組化機制引入到訪問控制策略中，利用上下文信息動態地控制用戶分配和權限分配，利用組化機制進一步簡化授權，實現了細粒度的訪問控制，滿足了企業統一資源訪問控制的需求。
