Embodiment Construction

[0030] In order to better illustrate the purpose and advantages of the present invention, the implementation of the method of the present invention will be further described in detail below in conjunction with examples.

[0031] The experimental data comes from the ICT bidding project data set, a total of 2043 data. Split the training set and test set at a ratio of 4:1. The experiment uses the accuracy rate (Accuracy) to evaluate the evaluation results of the node availability evaluation model. The calculation method of the accuracy rate is shown in formula 1:

[0032]

[0033] Among them, TP is the number of predicting the availability of positive nodes as positive, FN is the number of predicting the availability of positive nodes as negative, FP is the number of predicting the availability of negative nodes as positive, and TN is the number of predicting the availability of negative nodes as positive. Availability is predicted as the number of negative classes.

Abstract

The invention relates to an ICT supply chain network node availability evaluation method fusing market layout characteristics, and belongs to the technical field of computer and information science. The method mainly aims at solving the problems that an existing ICT supply chain network node availability evaluation index system is incomplete and an evaluation method is incomplete. The method comprises the following steps: firstly, quantifying information such as enterprise types, registration capital, establishment dates, registration states, enterprise residences and branch mechanismsto acquire supplier node commercial features; representing text description of an enterprise operation range as a text vector through a doc2vec algorithm, obtaining supplier node product features, and obtaining market layout features by quantifying individual influence margins, product layouts and industry layouts of supplier nodes; and finally, fusing the three types of features and constructing a supplychain node availability quantitative evaluation model of the blending ensemble learning, and outputting node availability rating (level 3: strong, strong, general). Experiments are carried out on anICT bidding and tendering project data set obtained by a project, and supplier availability rating task accuracy reaches 77.07%.

Description

technical field [0001] The invention relates to a method for evaluating the availability of ICT supply chain network nodes that integrates market layout features, and belongs to the field of computer and information science and technology. Background technique [0002] The ICT supply chain is a globally distributed complex system with multidimensional characteristics such as supplier diversity, product service complexity, and full life cycle coverage. Availability refers to ensuring that the ICT supply chain can be supplied normally in accordance with the agreement signed with the demand side and is not easily interrupted by human or natural factors. Studying the availability of ICT supply chain network nodes is of great significance for optimizing the supply chain network layout and improving the stability of the supply chain network. [0003] Complex network theory is an important tool for studying complex systems and is widely used in many fields. Using the method of co...
