This paper devoted to propose a human-machine integrated simulation method to evaluate the effect of corrective maintenance (CM) strategies on manufacturing cells considering the worker's autonomous and collaborative behaviors. First, a human-machine integrated model is developed to integrate the worker behaviors in the CM process by using agent technology. In this way, worker's dynamic and cooperative...
A novel white rot fungus strain Hohenbuehelia sp. ZW-16 was identified and first used for bioethanol production in this study. It was found that the strain could produce bioethanol with glucose, xylose and arabinose under limited oxygen condition. Then, corn straw hydrolysate and corncob hydrolysate (mainly composed of glucose, xylose, and arabinose) were used for bioethanol production; the former...
Polymer flooding for high-salinity reservoir is one of the most important technologies for enhanced oil recovery (EOR). In this paper, an optimal control problem (OCP) of a distributed parameter system (DPS) is established, in which the functional of performance index is profit maximum and the governing equations are the fluid equations in porous media. The control variables are chosen as the polymer...
In cellular manufacturing, it is essential to focus on human issues such as worker assignment strategies, skill identification, teamwork and communication. In order to analyze the impact of collaborative work in cellular manufacturing, agent model of workers was developed and integrated into the production simulation model. Then, comparative simulation experiments of different collaborative work schemes...
The periodic stable robustness of serial production line with single processing parameter is analyzed based on max-algebra. A searching algorithm based on golden section method to calculate the bound of perturbation of processing parameter is also proposed. Example shows that the algorithm can get the bound of the perturbation effectively, which is meaningful to actual serial production line.
Continuous stirred tank reactor is widely used in polypropylene production with typical nonlinear, time-varying and large time-delay characteristics. In this paper, an advanced control strategy is applied to the continuous stirred tank reactor in which the polypropylene polymerization reaction takes place. On the basis of analyzing the characteristics of polypropylene production process in detail,...
