In this paper, the forwarding objective and the mobility law of nodes in opportunistic networks are investigated to establish a mathematical model for further analysis, and then a new data forwarding algorithm is proposed. In this algorithm, according to the distance between the data holders and the destination, some intermediate nodes are selected to relay the data. Especially, the forwarding copies...
This paper addresses the problem of optimizing cyclic schedules in polyamide staple fiber plants. The problem concerns the scheduling of a production consist of two sequence of stages each involving one production line that are interconnected by intermediate warehouse. A mixed integer programming (MILP) model for cyclic schedules in polyamide staple fiber plants is formulated according to traveling...
To make multiattribute decision with incomplete information, the paper proposed a method based on rough set. The paper defined the concepst of breaking points, scan vector and the addition of scan vector to recover the incomplete information system through rough set. Then introduced OWA (ordered weighted averaging) operators to calculate the aggregation value of each project. Finally, obtained the...
