With the development of information technology in the new era and the continuous improvement of China's international status, the market competition pressure is increasingly fierce. For enterprises, the favorable competitive position and core advantages are particularly important. As the gateway of national foreign trade, if the port wants to provide better products and services, it must cater to the complex and changeable international and information market environment, accelerate the more advanced and scientific information process, and improve its competitiveness. In this paper, we from the perspective of the business process of the bulk cargo business system, analyzing the current barge operation system of Guangzhou port. We take the needs of port staff and customers as the starting point, find the current business process deficiencies, and improve and optimize. Finally, it is applied to Guangzhou port bulk cargo business system, which can be used stably and meet the business needs.
随着新时代信息技术的发展和中国国际地位的不断提高,市场竞争压力越来越大。对于企业而言,良好的竞争地位和核心优势尤为重要。港口作为国家对外贸易的门户,要提供更好的产品和服务,就必须适应复杂多变的国际和信息化市场环境,加快更加先进、科学的信息化进程,提高竞争力。本文从散货业务系统的业务流程出发,对广州港目前驳船业务系统进行了分析。我们以港口员工和客户的需求为出发点,发现当前业务流程的不足,并进行改进和优化。最后将其应用到广州港散货业务系统中,运行稳定,满足业务需求。

This paper establishes a comprehensive evaluation model based on entropy weight method and grey correlation analysis method, quantifies the importance of each supplier to the enterprise, and finally gives the ordering and transportation plan of the enterprise in the next 24 weeks. Firstly, four indicators reflecting the characteristics of suppliers are mined based on the order quantity and supply quantity. Then the entropy weight method is used to calculate the weight of each index, and the two methods of normalization, weighting and grey correlation analysis are directly quantified respectively to obtain the most important 50 suppliers. After comparison, it is found that the 5-year supply quantity of suppliers obtained by the entropy-grey correlation analysis model is 4302,643m3, accounting for 97.79% of the total supply quantity of 204 suppliers, which is 3.3% better than the result obtained by direct entropy weight method. Then, the supply quantity of the next 24 weeks is obtained through the time series prediction model and statistical analysis method, and the minimum number of suppliers is 37, as well as the corresponding ordering and transportation plan of the next 24 weeks, and the plan is analyzed through visualization.
本文建立了基于熵权法和灰色关联分析法的综合评价模型,量化了各供应商对企业的重要性,最后给出了企业未来24周的订货和运输计划。首先,基于订货量和供给量挖掘出反映供应商特征的四个指标。然后利用熵权法计算各指标的权重,分别采用归一化、加权和灰色关联分析两种方法直接量化,得到最重要的50家供应商。对比发现,采用熵灰关联分析模型得到的供应商5年供给量为4302,643m3,占204家供应商总供给量的97.79%,比直接熵权法得到的结果提高了3.3%。然后,通过时间序列预测模型和统计分析方法得到未来24周的供应量,最小供应商数量为37家,以及相应的未来24周的订货和运输计划,并通过可视化分析计划。

In the Internet financial industry, it is of great significance to the user's credit default risk management, but the traditional machine learning model has low prediction accuracy. This paper proposes a two-stage credit default identification model based on BP-RF (Back Propagation Neural Network with Random Forest). Firstly, the feature of transaction data is extracted automatically by constructing the neural network, and then classified and predicted by the random forest algorithm. The model is verified with millions of data sets provided by the lending club. The results show that the model has better performance than the traditional model, with an accuracy of 95.1%, AUC index of 89.0% and ACC index of 93.1%, which proves that the model is more suitable for the field of credit default prediction.

In the era of big data, sharing economy relies on the rapid development of data analysis and acquisition technology, and it also drives the fast growth of short-term rental housing in the sector of housing. In this process of development, there are many deteriorating management problems, such as infringement of rights, potential fire hazards and disclosure of privacy. The resulting conflicts and disputes, accidents, and the issues of the public safety become more and more serious. In the face of the chaos of the short-term rental housing industry, according to the sample statistics and Internet big data research, this paper plugged up the management loopholes in the short-term rental housing management from the perspective of joint construction, joint governance and shared benefits in the new era. In terms of method, this paper analyzed the data by constructing the integral model, took the safety risk issues existing in the daily operation of short-term rental housing as the index, and established the model of “quantitative integral early warning mode for abnormal problems of short-term rental housing”. Besides, it divided the risk of short-term rental housing into three levels, i.e. medium-low risk, high risk and tremendous risk, and carried out the corresponding risk classification management.
在大数据时代,共享经济依赖于数据分析和采集技术的快速发展,也带动了短租住房在住房领域的快速增长。在这一发展过程中,出现了许多日益恶化的管理问题,如侵权、火灾隐患、隐私泄露等。由此产生的冲突纠纷、事故、公共安全问题日益严重。面对短租住房行业的乱局,本文通过样本统计和互联网大数据研究,从共建、共治、共享的角度,堵住了新时代短租住房管理中的管理漏洞。在方法上,本文通过构建积分模型对数据进行分析,以短租住房日常运营中存在的安全风险问题为指标,建立了“短租住房异常问题定量积分预警模式”模型。并将短租住房风险分为中低风险、高风险和巨大风险三个级别,进行相应的风险分类管理。

By analyzing the previous order quantity, supplier's supply quantity and transshipment homeopathy quantity, this paper designed the ordering scheme of raw materials for a building and decoration board manufacturer, and considered the transportation of raw materials. First of all, this paper finds four factors that affect suppliers: total supply quantity, supply times, supply satisfaction rate and average supply completion rate, determines the coefficient by AHP, and considers scoring, and selects 50 most important suppliers. Next, select the important suppliers from top to bottom, and order their historical maximum supply every week until the maximum production capacity is met. According to the order price, give priority to a and c, and reduce b. Finally, select materials with low loss and high transportation yield. Finally, the number of selected enterprises is increased, and the most Class A materials and the least Class C materials are purchased, so as to maximize the production capacity and minimize the losses while ensuring that one supplier is transported by only one forwarder.
