It is being widely studied how to extract knowledge from a decision table based on rough set theory. The novel problem is how to discretize a decision table having continuous attribute. In order to obtain more reasonable discretization results, a discretization algorithm is proposed, which arranges half-global discretization based on the correlational coefficient of each continuous attribute while considering the uniqueness of rough set theory. When choosing heuristic information, stability is combined with rough entropy. In terms of stability, the possibility of classifying objects belonging to certain sub-interval of a given attribute into neighbor sub-intervals is minimized. By doing this, rational discrete intervals can be determined. Rough entropy is employed to decide the optimal cut-points while guaranteeing the consistency of the decision table after discretization. Thought of this algorithm is elaborated through Iris data and then some experiments by comparing outcomes of four discritized datasets are also given, which are calculated by the proposed algorithm and four other typical algorithras for discritization respectively. After that, classification rules are deduced and summarized through rough set based classifiers. Results show that the proposed discretization algorithm is able to generate optimal classification accuracy while minimizing the number of discrete intervals. It displays superiority especially when dealing with a decision table having a large attribute number.

When analyze the uncertainty of the cost and the schedule of the spaceflight project, it is needed to know the value of the schedule-cost correlation coefficient. This paper deduces the schedule distribution, considering the effect of the cost, and proposes the estimation formula of the correlation coefficient between the in（schedule） and the cost. On the basis of the fact and Taylor expansion, the relation expression between the schedule-cost correlation coefficient and the in-schedule-cost correlation coefficient is put forward. By analyzing the value features of the estimation formula of the in-schedule-cost correlation coefficient, the general rules are proposed to ascertain the value of the schedule-cost correlation coefficient. An example is given to demonstrate how to approximately amend the schedule-cost correlation coefficient based on the historical statistics, which reveals the traditional assigned value is inaccurate. The universality of this estimation method is analyzed.

创新链与产业链融合发展能优化双链协同性和开放性,增强比较优势和创新链韧性,使得创新更容易发生,产业链分工更加紧密。双链融合内在驱动力主要得益于创新基础能力的强化、产业内创新与产业间创新的广泛开展。从创新基础能力、产业内创新网络、产业间创新网络3个维度设计评价指标体系,利用产业数据和技术专利数据对中国及部分OECD国家的产业链与创新链融合情况进行对比分析。研究发现:总体而言,我国创新链产业链融合指数水平近30年来实现大幅提升,目前与日本相当,高于韩国及OECD平均水平,但落后于美国和德国,在一些关键核心技术领域与全球领先水平相比仍有差距,双链融合发展存在不容忽视的风险。为此,需聚焦关键核心技术创新重点领域,不断完善高端要素体系,夯实双链融合基础能力,促进产业间融合创新和地区间互补创新。

再生资源循环利用产业作为推动经济转型和实现可持续发展的关键力量,在全球范围内受到高度重视。该产业通过回收和再利用废弃物,有效减少对原生资源的依赖,缓解资源短缺问题,同时降低环境污染,促进生态平衡。在经济增长方面,它能够创造新的就业机会,增加税收,推动经济多元化发展。技术进步为产业带来创新动力,提高资源的循环利用率,而社会可持续发展则依赖于这一产业对资源和环境的双重贡献。贵州省凭借其丰富的自然资源和政府的政策扶持,在再生资源循环利用产业方面展现出巨大潜力。然而,资金不足、技术水平相对落后、产业链条不够完善以及专业人才短缺等问题,制约了产业的快速发展。为了解决这些问题,应基于系统性思维和政府引导原则,建立一套全面的多维度政策框架,包括财政支持、税收优惠、金融投资激励和市场监管等措施,旨在全面提升资源的利用效率,推动产业向绿色低碳方向转型。

Earth observation satellite system （EOSS） is the main space platform to collect ground information. Op- timization of EOSS is still a difficult problem, as it is a complex system concerning a great deal of design variables and uncertain factors. To solve the problem, an optimization framework based on parallel system and computational experi- ments is proposed. An artificial system for EOSS is firstly constructed, which is the integration of resource data, task data, environment data and related operation rules. Real EOSS together with artificial EOSS constitute the parallel systems for EOSS. Based on the parallel systems, concept of computational experiments is detailed. Moreover, surrogate models are built to approximate real EOSS. Genetic algorithm and improved general pattern search method are adopted to optimize the model. According to the framework, a case study is carried out. Through the results, we illustrated the proposed framework to be useful and effective for EOSS optimization problem.
