Location information and positioning technology are important to some Internet of Things (IoT) applications. The accuracy of indoor positioning using WiFi can be substantially enhanced by appropriate access point (AP) placement strategies, i.e., in a given indoor environment to deploy the WiFi APs at the locations where the mobile devices can work out their location more precisely. The plan of AP...
The mechanism and placement process of multi-head gantry mount machine (MHGM) is analyzed. Based on the engineering analysis, the optimization problem of placement process is decomposed to component grouping, component group pickup and component group placement problems, an integrated optimization model of MHGM is formulated, the minimum displacement of arm is objective. The component size, nozzle...
Based on the analysis of dual-gantry turret machine, the optimization problem of placement process is decomposed to component allocation, feeder arrangement and component placement sequence. Through the engineering analysis, an integrated optimization model of dual-gantry multi-head turret placement machine is formulated. The minimum displacement of gantry and workload balance is objective. Combined...
A class of order optimization (OO) with optimal computing budgets allocation (OCBA) based genetic algorithm (GA) is designed to perform local search in the framework of nested partitions method (NP). The local searching algorithm borrows from the idea of OO to ensure the quality of the design found with a reduction in computation effort and applies the evolutionary searching mechanism and learning...
The component placement sequence and feeder arrangement are two critical factors determining the assembly time of chip-shooter machine. In addition, the different size of component and different arrangement strategy affect the feeder arrangement and component placement sequence. Based on the engineering analysis, an integrated optimization model of chip-shooter machine is established. The improved...
