Based on genetic algorithms, an intelligent scheduling optimization of job-shop with multiple process plans is studied. Anew scheduling algorithm is proposed, whichcombines the genetic algorithms with dispatching rules.
Based on the thorough study of quantitative comparison of CAPP multiple process planning,a mathematical method of quantitative technical-economic evaluation of CAPP system is deduced in this paper.
The present dissertation uses Petri nets (PN) and hybrid genetic algorithms as tool to study the scheduling optimization of job shop with multiple process plants.
To achieve process resources reuse and intelligent aided process decision-making,a model of multi-process evaluation and decision-making was proposed,which combined uncertain language evaluation and multi-attribute decision-making method.
In this model,multi-process schemes were extracted from enterprise process data warehouse through process clustering and correlation,and evaluation scheme set was formed by these process schemes.
An alternative process, namely, an indirect cathodic deprotonation of 5-substituted isoxazoles, can be realized with the use of MeOH or t-BuOH as the prebases.
Although most fermentation ethanol is currently produced in traditional batch processes with yeast, the ethanologenic bacteriumZymomonas mobilis is recognized as an alternative process organism for fuel alcohol production.
The purpose of this work is the development of a deterministic model for the biochemical synthesis of acrylic acid in order to explore an alternative process.
It is proposed as an alternative process, having sugarcane as feedstock, to the petrochemical-based ones that have significant environmental impacts for their production.
The three-stage approach developed incorporates materials flow considerations while determining machine groups, considers alternative process plans, exploits part routing information and allows the user to perform sensitivity analysis.
The separation can be of broader interest; it originates from the rigorous calculation of matrix elements; it visualizes, in the language of spin amplitudes, the properties of factorization necessary for the common multi-process picture.
The indices Cpu ,Cpl , and Cpk have been used previously for evaluating a multi-process product with smaller-the-better, larger-the-better, and nominal-the-best specifications.
