主机资源远程控制系统研究与设计

主机资源的安全可控越来越受到人们的重视,尤其是在主机被盗、丢失等情况下,如何进行远程控制确保主机资源的安全是亟待解决的问题。针对这一现实需求,文章在分析了远程控制和主机文件安全删除两个方面的国内外研究现状的基础上,设计实现了一个主机资源远程控制系统,给出系统功能结构和工作流程,详细介绍了基于远程通信模块的硬件平台和管控指令的传输、安全身份认证、主机资源管控等控制软件的设计实现方法,并进行了系统功能测试和分析。该系统基于移动通信模块和主机资源管控代理实现,将通信模块内置于受控主机并通过USB接口与主机进行连接,受控主机运行管控代理软件,管理员的控制指令以短消息的形式发送。为增强系统的安全性,管控代理在接收到控制指令后需向管理员进行身份认证,通过认证后,管控代理执行管控指令,实施如删除敏感文件、关闭主机端口等操作。经实验验证,该系统达到了设计要求,可有效提高主机资源安全管理水平,大大降低主机失控可能造成的安全威胁。

Multi-agent Systems and Cloud Computing for Controlling and Managing Chemical and Food Processes

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.

Modeling of Raw Materials Management on the Example of Textile Production Company

The aim of this paper is to propose a discussion about inventory control and to present a new method for testing the control process in terms of uncertainty. The subject matter is modelling for optimal control that ultimately provides the basic parameters for the level of safety stock and the cycle of deliveries. An optimisation criterion is a function minimising the total costs of storage and production coming to a halt because of depleted stock of inputs. Considering the results of the study, it is found that appropriate management process of textile companies requires determining raw materials stocks and its costs very precisely. The stream management process in the enterprise includes an element of fluctuations in demand. This is the source of ＂a conflict＂ that appears in two sub-systems： storage and production. At the same time, a systemic approach to the optimal coordination of supply/production calls for effective management of the whole system. Implementation of modem information technologies is one of the factors that support the effective control.
