The deficiencies of current access control techniques in solving the problems of manufacturing process access conflict in networked manufacturing environment were analyzed. An information model of manufacturing process was constructed, and a case XML Schema of manufacturing task model was given. Based on the characteristic analysis of the access control for the information model, an improved ac...

In this study, the authors developed three new approaches and models for improvements related to manufacturing processes. The main focus was on planning in a digital environment before the actual manufacturing process is carried out. The first approach is digital manufacturing, which gives affords the opportunity for performing an entire manufacturing process in a virtual environment. In this w...

the optimum fermentation times of black tea manufactured by two systems of orthodox and ctc (cut, tear & curl) were investigated by measuring the quality parameters of black tea, like: theaflavin, thearubigin, highly  polymerized substances and total liquid colour during the fermentation stage. optimum fermentation times from the beginning of fermentation were determined to be 60 min and 15...

A local and temporal separated manufacturing becomes possible, which can enhance the economic efficiency of the production. Complex products such as spacecraft, large CNC Machine, large compressor face challenges in their development process. The cloud manufacturing which is based on the development of cloud computing and Internet of Things system makes the collaborative manufacturing process o...

Process planning plays an important role for ensuring machining quality, reducing production cost, and shortening leading time. Since there are many uncertainty factors for manufacturing resources in a changing manufacturing environment, especially for small batch manufacturing of large scale parts requiring long process planning time, manufacturing companies are facing significant challenges o...

Additive Manufacturing describes the technologies that can produce a physical model out of a computer model with a layer-by-layer production process. Additive Manufacturing technologies, as compared to traditional manufacturing methods, have the high capability of manufacturing the complex components using minimum energy and minimum consumption. These technologies have brought about the possibi...
