Method and system for matching community-based manufacturing service oriented to uncertainty of supply and demand

Abstract

The invention discloses a method and a system for matching community-based manufacturing service oriented to uncertainty of supply and demand. The method includes: updating the integrated service quality function values of each manufacturing service encapsulated as a Web service at fixed time intervals; dividing the service matching time window into an initial time window and an adjustment time window by selecting a time demarcation point. In the initial time window, candidate service sets of each requirement are screened from each manufacturing service; the candidate service with the best function value is used as the matching service of each requirement and the training sample. The average value of the customer satisfaction of the training sample set is obtained: if it is lower than thefirst preset threshold value, the machine learning algorithm is used to train the integrated service quality function according to the weight value of the service quality attributes in the training sample and the customer satisfaction degree, and the weight parameters of the function are updated; in the adjustment window: according to the function, the function value of each candidate service is calculated, and the optimal candidate service is regarded as the matching service corresponding to the demand.

Description

technical field [0001] The invention relates to the technical field of manufacturing services. More specifically, it relates to a method and system for matching social manufacturing services for uncertain supply and demand. Background technique [0002] With the development of information technology, enterprises rely on the business modules in their own information systems to encapsulate their manufacturing capabilities on the Web, and register and publish service resources through the platform. Collaborative manufacturing between enterprises needs to be realized through the dynamic combination of service resources. [0003] The social manufacturing model (Social Manufacturing), which efficiently interconnects and matches scattered and various types of social enterprise manufacturing service resources and customers through social media tools, and customers only use media tools to publish professional service outsourcing online , You can realize the whole process from produ...

[0006] Second, the uncertainty of customer needs and preferences: In fact, due to the limitations of customer sample selection and the ambiguity of customer needs, it is very difficult to give the weight of service attributes that meet the actual needs of customers

However, in the social manufacturing model, the demand preferences of different customers are very different, some pay special attention to the realization of certain indicators, such as price, quality, cost, etc.; some hope that the comprehensive indicators can be more balanced; and for different The attention weight of service attributes will also vary over time

[0007] In practical applications, the above uncertain factors will directly affect the subsequent service matching effect

How to realize the matching of supply and demand of social manufacturing services in an uncertain environment has become one of the key challenges hindering the practical promotion and application of social manufacturing models
