The algorithm is proved to be convergent theoretically and implemented for numerical calculation.Thirdly, two kind problems of multi-unit system maintenance based on the discrete-state deterioration model are analyzed:To achieve the optimization aim of series system consist of two types of units with different failure mode, an opportunistic policy is presented to combine the corrective and condition-based maintenance. The optimal model based on this policy is built and an iteration algorithm based on sequential decision is proposed according to the characteristic of discrete-state deterioration model.

第三、在部件优化分析的基础上，针对基于离散状态劣化模型的多部件系统视情维修决策中的两类典型问题，提出了相应的机会维修策略和优化分析方法：(1)针对串联系统由分别采用视情维修和事后维修的两类部件组成的情况，提出了一类事后维修与视情维修相结合的机会策略，建立了相应的多部件系统维修优化模型，并根据离散状态劣化模型的特点，提出了一类基于序贯决策的求解方法。

Simulation results are included to show that the optimal policy given by this method can well approach to the accurate one given by value iterative method on the case of having complete information, and the constringent rate of policy is quickly than others.

Numerical solutions show that stockholders choose to exercise the investment option too early compared to the unleveled enterprise. Compared with value-maximizing policy, stockholders are inclined to overinvestment under the equity-maximizing investment policy, which affects the investment option value and optimal leverage choice, and does harm to the interests of bondholders. When debt constrained, the enterprise decreases the investment trigger first, and then increases it as constraints become more binding.

数值计算显示，与无负债企业相比，杠杆企业具有过度投资倾向以加快实现负债融资所带来的利息税盾价值；与企业价值最大化策略相比，在股东权益最大化目标下，股东具有较早执行投资期权的动机，影响投资期权价值和最优财务杠杆的选择，并侵害了债权人的利益。

This paper endogens carbon tax and subsidy two variables, discussing how to decide the optimal level of carbon tax and subsidy. The results of the research are obtained as the following:(1) price and capital subsidy which one is priority depend on the productivity of renewable energy capital, if productivity is high enough, then should adopt capital subsidy policy;(2) price and capital subsidy indeed exist trade-off and non-independent relationship;(3) renewable energy regulation ratio has negative effect on carbon tax, however has positive effect on price subsidy;(4) green certificate price increase will result in decrease carbon tax and price subsidy, but increase capital subsidy;(5) if the authority loose the environmental target, then should impose high carbon tax which maintains the environmental quality, but have ambiguous effect on subsidy policy;(6) increasing stability of renewable energy, then increase price subsidy, however, under budget constraint should decrease capital subsidy;(7) analyzing Taiwan's three wind power energy with different price subsidy, which can improve the technology of wind power energy. In another word, it can raise the capacity of wind power energy and reach the goal of renewable energy.

本文考量政府预算限制下，探讨最适碳税税率与补贴率订定之问题，获得如下发现：(1)发电量补贴与资本补贴对促进再生能源发展效果不一样，决定於再生能源资本的生产力，如果资本生产力足够高，则发电量补贴效果较佳；反之，则应优先采行资本补贴措施；(2)发电量补贴与资本补贴的确存在抵换而非独立关系，亦即在政府预算限制下，为促进再生能源发展，应将种种补贴措施整合考量，以最低行政成本达到再生能源发展目标；(3)再生能源管制配比与碳税税率及资本补贴率呈反向变化关系；而与发电量补贴呈正向关系；(4)绿色权证交易制度具促进再生能源管制目标达到之奖励效果，因此，绿色权证价格提高可降低发电量补贴及碳税税率，降低碳税对经济不利冲击效果；(5)政府如果采行较宽松环境目标，宜提高碳税税率，避免环境品质进一步恶化，然而，对发电量或资本补贴之影响效果不确定；(6)再生能源发电效率愈高，则应提高再生能源发电补贴，在预算限制下，应降低再生能源资本补贴；(7)透过台湾三座风力机组的实证分析，采取差异性发电量补贴，将可诱导较高效率风力机组的投资行为，提高整体风力发电效率，达到再生能源发展之目标。

The modern policy study indicated that the main functions of the policy should adjudge the benefits and values allotment and the main researches trend to the policy analysis from the economic aspects.

现代政策学研究表明，政策的主要功能是利益调节和价值分配，而从经济角度进行政策分析是政策研究的主要方向。

In addition, access control policies of aggregated resources can be formulated as expressions of the algebra. Several algebraic properties of policy expressions are discussed. It shows that the algebraic properties of policy expressions can be used to verify whether policy composition results meet the protection needs of each party.

In every policy, there must be some security authentication information,such as one policy Authorizer, one Licensee, one TimeStamp, one LifeTime and a digital Signature, and some policy management information:At last, this paper designs and implements a HywaveGuard models instance based on Windows OS.

每个策略都有策略发布者，接受者的证书，策略制定的时间戳及有效期，同时还要附上发布者的数字签名，这些信息用于保证策略的安全验证；每个策略还可包含策略管理命令及策略内容，这些信息用于保证有效的策略管理与节点间通信。最后，针对当前网络的实际情况，本文在Windows系统平台上设计与实现了HywaveGuard防火墙模型的一个实例。

To regulate policy composition and guarantee its correctness, an algebraic model called APoCA (attribute-based access control policy composition algebra) is proposed for composing access control policy. In APoCA, an authorization relation between entities is described at the attribute level. APoCA fertilizes the existing formal frameworks by taking into account the computation of attribute values.
