Optical interconnects, which support the transport of large bandwidths over warehouse-scale distance, can help to further scale data-movement capabilities in high performance computing (HPC) platforms. However, due to the circuit switching nature of optical systems and additional peculiarities, such as sensitivity to temperature and the need for wavelength channel locking, optical links generally...
Addressing problems of larger volume of harmonic gear in the conventional design, in this paper, a mathematical model of optimization with hybrid discrete variables is proposed by taking the modulus of harmonic gear transmission parameters m, the length of flexspline L, wall thickness δ and tooth width of flexspline b as design variables, and the sum of volume of circular spline and flexspline as...
In continuous production process, there are many complex equipments and special requirements such as continuity and stability, which are very difficult to be presented in classical MINLP formulations. So the production scheduling for continuous process is more difficult than that for discrete process or batch process. In continuous process, experience rules usually play very important roles. But it...
Planning and scheduling of the flow of crude oil are very important problems in petroleum refineries. Since they emphasize on different apartment of plant, there are more optimized space in scheduling layer after plan optimization. The core of this article is to treat the scheduling problem when transitions occur by feedstock from tanks to crude distillation units. A scheduling model is built as the...
