Cases studies of the proposed system application in three cement factories in Algeria, SCAEK（Setif）, SCIMAT（Batna）, and SCT（Tebessa）, are discussed. The remote process control consists of alarms generated during running of the processes while maintaining and synchronizing different regulation loops thus ensuring automatic running of processes smoothly. In addition, fuzzy control of the kiln and the other two mills ensures that the system is operational at all times with minimal downtime. The process control system contains different operator station（OP）, alarms table and a provision to monitor trends analysis. The operator can execute any operation according to his authorised access assigned by the system administrator using user administration tool. The Internet technology is used for human security by avoiding all times presence of operators at site for maintenance. Further, in case of a breakdown, the problem would be remotely diagnosed and resolved avoiding requirement of an expert on site thus eliminating traveling cost, security risks, visa formalities, etc. These trips are difficult to organize（costs, visas, risks）. So the enterprise can reduce downtimes and travel costs. In order to realize a process control system guided by operators in the main control room or through Internet, the process control is based on programming in PCS 7 utilizing Cemat library and Fuzzy Control＋＋ Siemens tools.展开更多

In addition, seeking the answer to the question： what is working and how to change the model of personnel management in telework？ To find the answers to these questions, the author conducted a survey of managers of this type. In addition, research shows that management system has evolved significantly. And although still requirement changes, the activities are quite flexible, and adapted to the staff.展开更多

Yet, since teleworkcan give the area economic advancement without huge development, make mixed-use zoning plausible, and grantssense of community, it could bring physical, economic and social sustainability to local communities.LLCCP, as an example of emerging municipal ICT deployment programs, was examined on two levels;i.e. levelof urban policy and of urban design. It was revealed that LLCCP, as an urban policy, has a good potential to createICT-served work/life community, thus to contribute to the smart growth of the city. It does so by promoting new businessesyet small/home ones only, and developing new neighborhoods yet ICT-served work/life communities only. Itslink to regional plans and to the building code which ensures the connectivity in entire city elevate its possibility.The paper also pointed out that city’s urban design strategies are not yet supporting LLCCP toward its goal. Itlacks coordination with teleworkers’ life style, and with spatial system for the entire city. A current design proposaloverlooks teleworkers’ driving habits and their specifi c needs to the types of retails/business-services, for example. Theresult implies that the use of telework in creating sustainable community may have started to be recognized on urbanpolicy level, but that urban/architectural design for it is still behind to be developed.展开更多
