Embodiment Construction

[0039] A method for optimizing mechanical product services in a cloud manufacturing environment, combined with the accompanying drawings and specific implementation, is described in detail as follows.

[0040] This embodiment is based on the OS X EI Capitan system with 8GB memory, 2.9GHz Intel i5 processor, and the test software is Python 2.7.

[0041] Step 1. Decompose the demands of the demand side into n processes (the first 5 processes are examples in the table), and calculate the processing costs (time costs) and logistics costs for each service party respectively, as shown in Table 1 and Table 2.

[0042] Table 1 Each process task and the corresponding processing cost of the service enterprise

[0043]

[0044]

[0045] Table 2 The corresponding logistics costs of each process task and the service company

[0046]

[0047] Step 2: For ease of programming, customers and businesses are numbered in this article. The customer number from "customer to enterprise R1...

Abstract

The invention discloses a mechanical product service optimization method in a cloud manufacturing platform. First of all, according to user requirements, a user demand is decomposed into a plurality of subtasks; wherein each subtask corresponds to a plurality of service parties; the service time and the service cost are used as indexes; the k optimal service combination schemes are recommended tothe user by using the k optimal selection algorithm, the calculation complexity is reduced, the problem that the meta-heuristic algorithm is not easy to converge is avoided, and a reliable selection range can be provided for the user more efficiently and accurately, so that the time cost of the user in work is saved, and the enterprise competitiveness is improved.

Description

technical field [0001] The invention relates to an information processing method, in particular to a mechanical product service optimization method in a cloud manufacturing environment. Background technique [0002] Cloud manufacturing is a new manufacturing model proposed by Academician Li Bohu of Beijing University of Aeronautics and Astronautics in my country for the current situation of my country's manufacturing industry. Its core idea is to maximize the utilization of resources and reduce the waste of resources on the service side by integrating the resources of various service parties. Service optimization in cloud manufacturing mode is a hot and difficult issue in the research of cloud manufacturing mode. [0003] At present, the service optimization problem in the cloud manufacturing mode is to find the optimal service combination scheme of a certain index (service time, service cost, etc.) as the research goal, establish a mathematical model, and solve it through a...
