AF2/KDF2滤棒成型机三醋酸甘油酯雾化施加装置依靠轮辊高速旋转产生的离心力将三醋酸甘油酯甩抛成雾状后施加在丝束上,雾化颗粒和喷洒量不均匀,从而造成滤棒硬度不稳定、容易产生溶孔等问题。为此在研究借鉴KDF3,KDF4滤棒成型机雾化施加系统的基础上,对硬件和控制部分进行了改造,通过恒压作用,经喷嘴喷洒出雾化良好的三醋酸甘油酯,均匀地施加在丝束上。测试对比结果,滤棒硬度的过程能力系数由0.6提高到1.13,废棒率由0.54%降低到0.35%,三醋酸甘油酯的平均消耗由0.949 kg/万支降低到0.933 kg/万支,提高了滤棒质量稳定性,降低了原辅料消耗。 展开更多

Cloud computing can offer a very powerful, reliable, predictable and scalable computing infrastructure for the execution of MAS (multi-agent systems) implementing complex agent-based applications such when modelling, simulation and real-time running of complex systems must be provided. Multi-agent systems appears as an adequate approach to current challenges in many areas. Between important qualities of MAS also belongs to, that they are open, interoperable, and heterogenous systems. The agent is active, a program entity, has its own ideas how to perform the tasks of the own agenda. Agents: perceive, behave "reasonably", act in the environment, communicate with other agents. Cloud infrastructures can offer an ideal platform where run MAS systems simulations, applications and real-time running because of its large amount of processing and memory resources that can be dynamically configured for executing large agent-based software at unprecedented scale. Cloud computing can help chemical and food companies drive operational excellence; meet growing and changing customer demands; accelerate new product innovation and ramp-to-volume manufacturing in key markets; reduce IT spending; manage and mitigate supply chain risks; and enable faster and more flexible delivery of new IT system. Production type of SOC (service-oriented computing) can be inspired by a "Cloud", for the production of "Cloud" offers an attractive and natural solutions in several computing trends such as delivery system over the Internet, use of utilities, flexibility, virtualization, a "grid" distributed computing, outsourcing, Web 2.0, etc.. Production of the "Cloud" is also considered as a new multidisciplinary field that includes "network" production, virtual manufacturing, agile manufacturing, and of course cloud computing. Examples of cloud computing and MAS applications in food and chemistry development and industry, proposition of using multi-agent systems in the control of batch processes, modified ACO (ant colony optimization) approach for the diversified service allocation and scheduling mechanism in cloud paradigma, examples of applications in a business area were studied in the paper. 展开更多
