System and method for facilitating transactions between product brand managers and manufacturing organizations

A method is provided for facilitating transactions between a product brand manager and manufacturing organizations using a transactional computer system. The product brand manager has a product brand and product brand information that includes information for manufacturing the product brand, and there is manufacturing organization information for each of the manufacturing organizations that includes the manufacturing process capabilities of the respective manufacturing organization. The method includes communicating the product brand information from the product brand manager to the transactional computer system, and communicating the manufacturing organization information for the manufacturing organizations from the manufacturing organizations to the transactional computer system. The method also includes using the transactional computer system to process the product brand information and the manufacturing organization information to select at least one candidate manufacturing organization from the manufacturing organizations and to generate selection information regarding the at least one candidate manufacturing organization. The selection processing uses the transactional computer system to compare the product brand information to the manufacturing organization information. The method further includes using the transactional computer system to communicate the selection information to the product brand manager. A related method is provided for the selection of product brand managers for the benefit of a manufacturing organization. Related systems also are disclosed.

Cigarette working procedure quality overall evaluation system and method based on gray correlation analysis

ActiveCN101414183ASolve the ambiguous situation of process capability evaluationFunctional job improvementTotal factory controlProgramme total factory controlGrey correlation analysisProcess quality
The invention discloses a comprehensive cigarette process quality evaluation system based on grey correlation analysis and a method thereof, aims at overcoming the disadvantage that the existing single process evaluation method can not comprehensively evaluate the overall process quality of the cigarette process, and changing the situation of fuzzy process capability evaluation of a whole line at present. The evaluation system and the method thereof help comprehensively evaluates the quality of a plurality of processes, and can effectively grasp comprehensive situation of the process quality so as to provide basis for the continuous improvement in the process quality, and provide assurance for quality improvement of cigarette products. The system and the method combine the single-process quality evaluation method and the grey correlation analysis method. The method comprises the following steps: firstly, computing process capability indexes of various process parameters; then, comprehensively evaluating a Cpk value by the grey correlation method; finally, obtaining a comprehensive evaluation result which is taken as a process quality rank of various evaluated objects. Production practice can be effectively directed by analyzing the Cpk and the process quality ranking result.
