Green construction has been developed at an initial stage in China with serious problems, such as insufficient mobilization, management and supervision. The concept and connotation of green construction and its management was introduced in this study, where the current status and existing problems of green construction management in China was analyzed. It was proposed that scientific management and...
Based on the analysis of cold-chain process, it suggests using the theory of process control to analysis the critical control points in the cold-chain process, which influences the food safety. To identify the critical processes, this paper proposes a new and general decision making method for evaluating logistics systems using AHP and entropy weight method. Based on the integrated weight of criteria...
If the complicated system wants to be good running, it should have a stable initial condition. The function of checking hidden danger information system of the coal mine's production in the accident control becomes more and more important. Taking tunneling waking face, we established the checking hidden danger information flow by stages, based on systems' characteristics: Initial condition dependence,...
In the ldquodigital factoryrdquo tool chain, usually only the nominal production sequence, i.e. the production process under ideal conditions, is considered and automatically converted into PLC code. However, the nominal sequence is a prominent but rather small fraction of the total PLC code. The large remaining parts, such as interlock logic, safety functions, start-up and shutdown sequences, are...
The construction industry has been facing a paradigm shift to (i) increase; productivity, efficiency, infrastructure value, quality and sustainability, (ii) reduce; lifecycle costs, lead times and duplications, via effective collaboration and communication of stakeholders in construction projects. Digital construction is a political initiative to address low productivity in the sector. This seeks...
A selection is presented of fiber-optic and micro-optic devices that have been designed and tested for guaranteeing the quality and safety of typical foods, such as extra virgin olive oil, beer, and milk. Scattered colorimetry is used to authenticate various types of extra virgin olive oil and beer, while a fiber-optic-based device for UV-VIS-NIR absorption spectroscopy is exploited in order to obtain...
