Although simulation is typically considered as relevant and highly applicable, in reality the use of simulation is limited. The simulation system can provide an effective platform for the research of batch process fault diagnosis.īusiness process simulation : how to get it right?Īalst, van der W.M.P. ![]() A visual human-machine interactive simulation software system based on Windows operation system is developed. In this paper, penicillin fermentation, a typical non-linear, dynamic, multi-stage batch production process, is taken as the research object. The design of simulation system of batch process fault diagnosis is of great significance. It can ensure safety and provide products with consistent quality. Real-time monitoring for batch process attracts increasing attention. Qi, Xiaoyu Yuan, Zhonghu Qi, Xiaoxuan Zhang, Wenqi The results also show that although the DHSVM hydrological model has the potential to model the hydrology well in small mountainous catchments with very limited data in Tibetan Plateau, the simulation of hydrology in dry periods is not very satisfactory due to the model's insufficiency in simulating seasonal frozen soil.ĭesign of penicillin fermentation process simulation system The final results show that frozen soil and snow pack do play an important role in hydrological processes in cold mountainous region, in particular in dry periods without precipitation, while in wet periods precipitation is often the main source of runoff. The performance of simulation is evaluated with several evaluation indices. Based on sensitivity analysis results, the Epsilon-Dominance Non-Dominated Sorted Genetic Algorithm II (É›-NSGAII) is finally added into the hydrological model to calibrate the hydrological model in a multi-objective way and analyze the performance of DHSVM model. Global sensitivity analysis is applied to help determine the important processes of the catchment. Then, a distributed hydrology soil vegetation model (DHSVM) is adopted to simulate the hydrological process of Dong catchment based on limited data set. ![]() The sources of runoff in dry periods and wet periods are analyzed respectively. Annual and interannual variations of runoff indices are first analyzed based on historic data series. Two measurement stations are set up to collect basic meteorological and hydrological data for the modeling purpose. The Dong catchment, a small catchment located in Tibetan Plateau, is used as a case study. The objective of this study is to find out how much and in what way the frozen soil and snow pack will influence the hydrology of small mountainous catchments in cold regions and how can the performance of simulation by a distributed hydrological model be improved. Water cycle of small watersheds with seasonal/permanent frozen soil and snow pack in Tibetan Plateau is seriously affected by climate change.
