【摘要】：当今世界，人类生存环境问题日益凸显，节能减排、低碳已成为各国、各产业领域关注的焦点，，继信息化之后，经济领域的又将掀起一场绿色经济的重大革命。绿色的本质，在于更充分利用资源及更低的环境损耗，获取更高品质的生存需求。追求绿色化的过程，就是追求更高能耗性价比的过程。可以这样认为，在满足相同需求的基础上，既要追求船舶产品的经济性（生产力代价指标）最优，也要追求环保性（环境代价指标）最优。船舶营运过程中的备品备件保障程度关系到船舶可靠性的高低，又受到经济性与环保性的制约。决策者在每次航行任务中，既要使备品备件数量保障充足，确保船舶航行的安全可靠，又要避免保障过度，造成经济性与环保性上的不必要浪费。本文基于船舶全生命周期，提出以碳计量方法作为船舶绿色度评定的衡量指标，并在分析船舶可靠性、维修性的基础上，建立船舶故障树模型，给出了船舶备品备件绿色更换策略的决策模型。基于本文提出的决策模型，引入可变权惩罚函数，通过改进的经典搜索法和遗传算法求解多目标规划的局部最优解。应用本文提出的决策模型，对某型船舶进行仿真分析，获得该船舶备品备件的绿色更换策略。
[Abstract]:In today's world, the problem of human survival environment has become increasingly prominent, energy saving, low carbon has become the focus of attention in various countries, industries, following the information, the economy will set off a wave of green economy revolution. The essence of green, is the use of environmental resources and lower loss more fully, more high quality of life the pursuit of green demand. The process is the pursuit of higher energy cost. This can be considered on the basis of meeting the same requirements, not only to the pursuit of economic ship products (productivity cost index) of the best, but also the pursuit of environmental protection (environmental price index) is optimal.
The operation of the ship in the process of spare parts related to the degree of protection of ship reliability level, but also restricted by economic and environmental protection. The decision makers in each mission, should make the spare parts quantity guarantee sufficient to ensure that the ship navigation safety, and avoid excessive protection, resulting in unnecessary waste of economy and environmental protection on.
The ship based on the life cycle, proposed to carbon accounting method as a measure of ship green degree evaluation, and the analysis of ship reliability, maintainability based on established fault tree model, gives the decision model of ship spare parts to replace the green strategy. Based decision-making model proposed by Yu Benwen, by introducing a variable power penalty function the local optimal search method is improved and the classical genetic algorithm for solving multiobjective programming solution. A decision model is presented in this paper, the simulation analysis of a certain type of ship, the ship spare parts to replace the green strategy.
