In manufacturing outsourcing among supply chain enterprises, the supplier may misappropriate the knowledge shared by the manufacturer. Consider this knowledge misappropriation, we develop two Stackelberg game models to explore the profits of a manufacturer and a supplier selected from alternative suppliers under a wholesale price contract and a revenue sharing contract. We discuss the influence of knowledge misappropriation on the conditions when each alternative supplier can provide the optimal wholesale price contract or the optimal revenue sharing contract that makes both sides profitable, and then analyze the influence of knowledge misappropriation on the conditions when the manufacturer should select the supplier who provides the optimal wholesale price contract or the optimal revenue sharing contract. This paper contributes to the research on manufacturing outsourcing among supply chain enterprises.
在供应链企业之间的制造外包中,供应商可能会盗用制造商共享的知识。考虑到这种知识滥用,我们建立了两个Stackelberg博弈模型来探讨在批发价格合同和收入共享合同下制造商和从备选供应商中选择的供应商的利润。首先讨论了知识侵占对各备选供应商均能提供最优批发价格合同或最优收益共享合同且双方均能盈利的条件的影响,然后分析了知识侵占对制造商应选择提供最优批发价格合同或最优收益共享合同的供应商的影响。本文对供应链企业制造外包的研究有一定的贡献。

In general, old renovation refers to renovation design of old towns, factories, villages and other old areas and spaces. In this article, “old renovation space” mainly refers to the renovation design of some old factory spaces and area in Shanghai. As one of the largest international cities in China, industrial area of Shanghai accounts for a much higher proportion than other cities of the same type, so its land use, transformation of industrial area have become a focus of Shanghai’s urban renewal. In the transformation of industrial areas, art intervention plays a significant role, due to various art intervention techniques are used in different old areas, as a result, the effects are different. In this article, a relative analysis is made on continuity and timeliness of art intervention in different places through taking art intervention in old factory building of surrounding public areas, as well as external & internal organization forms and existence state of old factory building as the breakthrough point. Meanwhile, the adaptability and possibility of the art forms composition in the old city transformation space were discussed and suggested.
一般来说,旧改造是指对老城区、工厂、村庄等旧区域和旧空间的改造设计。在本文中,“旧改造空间”主要是指上海一些旧工厂空间和区域的改造设计。作为中国最大的国际化城市之一,上海的工业区占比远远高于其他同类型城市,因此其土地利用、工业区改造已成为上海城市更新的焦点。在工业区域的改造中,艺术干预扮演着重要的角色,由于不同的旧区域使用了不同的艺术干预技术,因此效果也不同。本文以艺术对周边公共区域老厂房的介入,以及老厂房内外的组织形式和存在状态为切入点,对不同地方艺术介入的连续性和时效性进行了相对的分析。同时,对旧城改造空间中艺术形式构成的适应性和可能性进行了探讨和建议。

This paper considers the static bike sharing repositioning operation that is essential to eliminate inventory imbalance among bike sharing stations caused by stochastic bike renting and returning in modern bike sharing systems. The operation aims to remove excess bike inventories from surplus stations and add needed bikes to insufficient stations in order to minimize both traveling cost and inventory cost. A hybrid variable neighborhood search (VNS) algorithm based on two grouping strategies is proposed to solve the static bike sharing re-positioning problem (s-BSRP). The two grouping strategies, namely, geolocation-based grouping and supply-demand-based grouping, are designed to construct station groups. Vehicle routes within each group and among groups are improved using a variable neighborhood search algorithm with local search, for which several neighborhood structures are designed. Extensive computational experiments are conducted on benchmark instances with various sizes taken from the literature. Performance of the proposed algorithm is compared with that of branch-and-cut and two other state-of-the-art algorithms. Computational results show the superior performance of the proposed grouping strategies and the hybrid VNS algorithm in solving large-scale BSRPs.
本文考虑了在现代共享单车系统中,为了消除由于随机的自行车租赁和归还造成的共享单车站点之间的库存不平衡,需要进行静态的共享单车重新定位操作。该操作旨在从剩余站点移除多余的自行车库存,并将需要的自行车添加到不足的站点,以最大限度地降低出行成本和库存成本。针对静态共享单车重新定位问题,提出了一种基于两种分组策略的混合变量邻域搜索(VNS)算法。设计了基于地理位置的分组和基于供给需求的分组两种分组策略来构建站点群。采用带局部搜索的可变邻域搜索算法改进组内和组间的车辆路线,并设计了若干邻域结构。广泛的计算实验进行了从文献中不同大小的基准实例。将该算法的性能与分支切断算法和其他两种最先进的算法进行了比较。计算结果表明,所提出的分组策略和混合VNS算法在求解大规模bsrp问题上具有优异的性能。

Aging is a major social problem in the process of rapid urbanizing China, but the current general elderly-care pattern usually emphasizes physical welfare and neglects spiritual wellbeing of the elderly. As the carrier of community spirit and memory, urban temples can meet new needs and realize social service value through space design. Taking the project of Xiao-putuo Guan-yin Temple as an example, this paper studies the spatial design of modern urban Buddhist temples from the aspects of function and spatial layout, dialogue between modernity and tradition, the shaping of religious atmosphere, and ecological planning and community garden. The study aims to provide useful reference for the construction of urban religious spaces in the aging society.

On the basis of recognizing importance of safe operation in power grid, more comprehensive evaluation index system is built in this paper for power grid engineering operations. Moreover, interval analytic hierarchy process is used to determine weight of evaluation index, which greatly reduces influence of subjective factors and makes evaluation index more scientific and reasonable. Besides, concept of interval number is introduced to minimize influence of subjective factors in determining weight of evaluation indicators. In addition, power grid operation is divided into four subsystems structure, equipment, management, and environment so that comprehensive evaluation and research on grid operation risks can be performed. What’s more, factors affecting power grid engineering are divided into static influence factors in which structure of power grid and operating status of equipment are concluded and dynamic influence factors where external environment and internal management are involved. Additionally, according to characteristics and requirements of power grid engineering, matter-element extension method is used to construct evaluation model and calculate its correlation degree. Besides it, combined with examples to prove applicability of model, it is pertinently pointed out that operation and maintenance management of equipment need to be strengthened so that professionalism and skills of management personnel can be improved, and safe and stable operation of power grid will be guaranteed.

Due to the characteristics of large commercial complex, such as large building scale, large amount of combustibles and large flow of people, fire accidents occur from time to time, but the mechanism of accident risk coupling disaster is still unclear. Based on the above problems, the risk coupling analysis of human, equipment, environment and management factors affecting the fire safety of large commercial complex is carried out, and the probability and risk value of different risk coupling situations are calculated by using the N-K Model. The results show that human is the key coupling factor; multi-factor risk coupling will increase the probability of accidents; at the same time, the coupling form with strong coupling should be avoided..
由于大型商业综合体建筑规模大、可燃物量大、人流量大等特点,火灾事故时有发生,但事故风险耦合灾害的机理尚不清楚。针对上述问题,对影响大型商业综合体消防安全的人、设备、环境和管理因素进行风险耦合分析,并利用N-K模型计算不同风险耦合情况的概率和风险值。结果表明,人是关键的耦合因素;多因素风险耦合会增加事故发生的概率;同时,应避免采用强耦合的耦合形式。

With the rapid development of the Internet, the “Internet +” model has been widely used. A new generation of security technology such as intrusion detection is urgently needed to ensure information security. In order to improve the detection efficiency of intrusion detection, IDS Snort research based on the classic clustering algorithm was performed. First, the traditional clustering algorithm, Kmeans algorithm, itself has some uncertain factors. The algorithm is optimized to make it better used in IDS Snort. Second, Combining the improved Kmeans algorithm with intrusion detection technology to improve Snort and analyze the advantages of applied to IDS Snort. Finally, the experimental results show that compared with the traditional Snort, the improved Snort has a significantly improved detection efficiency, which makes the intrusion detection technology further and the information security more reliable.

Study on Optimum Technology of Gas Control in Contiguous Outburst Coal Seams 连续突出煤层瓦斯控制优化技术研究
Pub Date : 2020-04-01 DOI: 10.1109/ICUEMS50872.2020.00163

During mining of contiguous outburst coal seams, a large amount of pressure relief gas near the seam was poured into the working face through roof and floor fractures. Consequently, substantial gas is emitted to the working face, leading to frequent alarm of methane sensors in the return air corner and in the return airway, Which seriously restricts the safe production of mines. In this study, through analysis and demonstration of several gas control schemes, the scheme took the whole coal seam group as a control unit and regarded the weak outburst coal seam with relatively small thickness and low gas content as the key protective seam. Meanwhile, in the scheme, three-dimensional borehole drainage was carried out to realize progressive protection. The field practice results showed that the gas drainage rate of the working face of protective seam reached over 90%; the gas concentration in the return air corner fell to below 0.6%; the maximum gas concentration in the return air flow was 0.15%; Meanwhile, the scheme fundamentally solved the gas-induced safety threats during the recovery of working face of protected seam.
在连续突出煤层开采过程中,煤层附近大量卸压瓦斯通过顶底板裂隙向工作面注入。因此,大量瓦斯向工作面排放,导致回风角和回风巷道的甲烷传感器频繁报警,严重制约了矿山的安全生产。在本研究中,通过对几种瓦斯控制方案的分析论证,该方案以整个煤层组为控制单元,以厚度较小、瓦斯含量较低的弱突出煤层为关键保护煤层。同时,在方案中采用三维钻孔排水,实现超前保护。现场实践结果表明,保护煤层工作面瓦斯抽放率达到90%以上;回风角气体浓度降至0.6%以下;回风最大气体浓度为0.15%;同时,该方案从根本上解决了受保护煤层工作面回采过程中的瓦斯安全威胁。

The field practice results showed that the gas drainage rate of the working face of protective seam reached over 90%; the gas concentration in the return air corner fell to below 0.6%; the maximum gas concentration in the return air flow was 0.15%; Meanwhile, the scheme fundamentally solved the gas-induced safety threats during the recovery of working face of protected seam.","PeriodicalId":285594,"journal":{"name":"2020 International Conference on Urban Engineering and Management Science (ICUEMS)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125795461","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The comprehensive management of coal mining subsidence area is a special problem in the sustainable development of coal resource-based cities. The construction of its statistical system will help government departments to grasp the present situation, problems and policy effects of comprehensive management of coal mining subsidence area more comprehensively, and provide basis for decision-making. Firstly, the statistical framework of comprehensive management of mining subsidence area is constructed based on “pressure-state-response” framework. Then, the statistical scope and contents of comprehensive management of mining subsidence area are determined. Finally, the statistical investigation system and method of comprehensive management of mining subsidence area are put forward.
