During the hydrometallurgical production process, there are many towers working at the same time. In order to improve production efficiency, we need to control the level height of every tower. Takes example for 6 towers, do research on the level control system in metal ions production process. According to the theory of materials balance, the mathematic model of the system are established. Programmed the mathematic model by Matlab. In order to make the level of each tower at the same height, work out how many adjust times needed and how much adsorbate every tower inflow and outflow each time. Then analysis the data results of error and variance, which have confirmed the feasibility and rationality of the level automatic balance system model established in this paper.

Basic and theoretical research on processes such as reverse osmosis (RO) is essential in the fermentation industry to improve production efficiency and reduce cost. Here, we focus on the RO concentration of glucose solutions. We constructed a mathematic model that incorporates various membrane and experimental parameters to characterize the mass transfer process of RO membrane and validated the model output with experimental data. Calculation results were highly consistent with the experimental data, demonstrating that this model can be useful for predicting the RO concentration process.

In this paper, a liquid level control system was designed and fabricated. Control of the liquid level was accomplished by adjusting the sup-ply voltage to a centrifugal pump that is delivering the liquid from a reservoir tank to an upper tank. The liquid level control system was implemented on an ATmega328 microcontroller. Three control strategies are implemented, manual mode, ON/OFF controller, and PID controller. Serial communication is used to establish the communication between the ATmega328 and a computer running MATLAB soft-ware. A graphical user interface was constructed to allow users to interact with the system. The system model is obtained using an experi-mental approach. The obtained model is then used for the design of the PID controller. Experimental results are provided to highlight the performance of the implemented controllers.

Improve Production Efficiency

To measure the performance of the production process, an efficiency calculation is performed using the Overall Equipment Effectiveness (OEE) method. OEE can measure various production losses and identify potential developments that can be carried out in a production process. This research is expected to be an input to improve production efficiency. The results of overall equipment effectiveness are then performed using Discrete Event Simulation, which built using STELLA Architect. The result shows that their overall equipment effectiveness scores are below the company goals, and performance rate is their lowest score. These simulation results are expected to be a basis for improvements in the production division, especially at Table Tennis Table Manufacturer.

The survey results from 8 agricultural cooperatives that have applied high technology, 5 agricultural cooperatives that have not applied high technology to their production, preservation, processing and consumption, and 5 enterprises have regular transactions with cooperatives surveyed based on questionnaires showed that high technology application has helped agricultural cooperatives in Long An province significantly improve production efficiency by being more proactive in production, reducing agricultural input costs and improving productivity and product quality. However, the scale of high techechnology applications of agricultural cooperatives is still small, scattered, high technology is mainly applied in some stages in the production process and in the crop sector due to lower capital requirements for high technology and other resource limitations of agricultural cooperatives as well as constraints on policies. Since then, the study has proposed a number of recommendations to promote agricultural cooperatives to apply high technology in agriculture more effectively.

This overview discusses how precision sheep management could be utilised in the Australian sheep industry to improve production efficiency and reduce animal welfare concerns due to low monitoring frequency by stockpeople. The concept of precision sheep management is described. This is a system in which sheep are managed as individuals or small groups rather than as a (whole) flock. Precision sheep management utilises the application of radio frequency identification technology, enabling producers to better monitor sheep in extensive situations, and contribute to improved efficiency of management and sheep welfare. Examples of combining radio frequency identification with other technologies such as walk-over-weighing and Pedigree Matchmaker are discussed. These technologies provide producers with tools to improve the cost effectiveness of, and labour efficiency associated with, collecting data on individual animals. The combined technologies should also improve consistency and reliability of information, enhancing decision-making by producers, for example, from regular monitoring of biometric variables such as liveweight, or calculating breeding values to enable superior genetic comparisons over time.
