Embodiment 1

[0198] According to the quantitative formulas (1)-(20) of the reconfigurable manufacturing system evaluation index, the six key characteristics of the reconfigurable manufacturing system are quantified. In order to fully reflect the characteristics of the PROMETHEE algorithm and avoid the interference of accidental factors on the calculation results, the design The five evaluation schemes are compared. The key feature quantification results of these five schemes are shown in Table 4. The quantification and quantification results are the starting point for the implementation of the PROMETHEE algorithm: the evaluation table.

[0200]

[0201] After the quantification of the key features is completed, the weight calculation of the indicators is carried out, and the importance of these six features is assigned by analyzing the characteristics of the key features and their importa...

Abstract

The invention discloses an evaluation method of a reconfigurable manufacturing system, based on PROMETHEE. The evaluation method comprises the steps that a decision maker formulates evaluation schemes before making a decision; each evaluation scheme comprises a plurality of evaluation indexes; different preference functions are respectively selected according to characteristics of the evaluation indexes; each scheme is evaluated through each evaluation index and a corresponding preference index value is computed; preference indexes are computed; the total preference relation between a scheme a and other schemes in a selectable scheme set A is computed; scheme ordering rules are formulated; the schemes are comprehensively ordered according to the defined ordering rules, and a complete ordering index phi (a) is defined, so as to cover the shortage of part of ordering indexes, and an ordering result is obtained according to the complete order index phi (a). The evaluation method has the benefits that the decision process is more close to the practicality, so that a more accurate evaluation result is obtained.

Description

technical field [0001] The invention belongs to the technical field of statistics and relates to a PROMETHEE-based reconfigurable manufacturing system evaluation method. Background technique [0002] With the development of the economy, the competition in the manufacturing industry has intensified, and the needs of customers have become more sophisticated and diversified, resulting in the continuous increase of product types and large fluctuations in market demand. The defects of the manufacturing system are gradually revealed, and the research on new manufacturing systems has gradually become a hot spot, pursuing the pursuit of producing high-quality products at low cost to gain a competitive advantage. At present, the reconfigurable manufacturing system (Reconfigurable Manufacturing System, RMS) is a model of the next generation of new manufacturing systems, which can provide precise functional and capability requirements according to customer requirements, attracting a la...
