“…Experiments results showed good results obtained from the MABCA in terms of assembly time. The [20] proposed an improved SFLA (I-SFLA2) to deal with the FAP and CSP simultaneously for a chip shooter. The experiments showed that the I-SFLA2 outperformed the PSO2 proposed in [1] as well as the improved SFLA proposed in [18].…”

“…Unlike the standard FA, the MDFA uses a different moving step for a firefly. Assume that ( )=[ , ( ); = 1, … , ] and ( )=[ , ( ); = 1, … , ] are two positions vectors of the fireflies i and j with the firefly i attracting the firefly j, the adaptive moving step of the firefly fly j is then defined by (20).…”

“…For instances, for the multi-head gantry machine, ABC has been used to deal with the Automatic Nozzle Change (ANC), Nozzle Assignment Problem (NAP), and Component Sequencing Problem (CSP) [17]; SFLA has been used to deal with the CSP [18]; APSO (adaptive PSO) has been used to deal with the CSP [19]. For the chip shooter machine, PSO2 (an improved PSO) has been used to deal with the FAP and CSP simultaneously [1]; Improved SFLA has been used to deal with the FAP and CSP [20]. However, to our best knowledge, there is still a lack of using FA to deal with the PCBA problems for a multi-head gantry SMT machine.…”

An optimal scheduling strategy for cooling, heating and power (CCHP) joint-power-supply system is proposed to improve energy utilization and minimize costs in this paper. Firstly, the mathematical model of CCHP system is established. Particle swarm optimization (PSO) is used to optimize the regularization coefficient C and the kernel parameter λ which can affect the prediction accuracy of KELM(PSO-KELM). Then PV generation and load prediction model are established by PSO-KELM. In order to jump out of local optimal solution, Cauchy variation is introduced in SFLA local update, and adaptive mutation operation is carried out on SFLA individuals. The predictions of PV generation and load power by PSO-KELM are imported into the objective function, and the microgrid dispatching model is solved by the improved SFLA algorithm. Compared with the traditional GA-KELM and KELM, PSO-KELM has faster convergence and prediction accuracy. Compared with the power supply division, the operation cost of the power grid is reduced by the proposed optimization dispatching strategy of CCHP micro-grid.

Surface Mount Technology (SMT) is a technique in electronic manufacturing to assemble electronic components on the surface of printed circuit boards. The industry has faced new challenges because of the increasing complexity of the assembly process to satisfy requirements such as lightweight, smaller size, and diverse configurations. With the usage of lead-free solder and the trend toward miniaturization in the electronics industry, the misalignment of solder paste has become more problematic. As the size of components decreases, it becomes more challenging to guarantee accurate placement and alignment during the assembly process. Self-alignment is a physical phenomenon during soldering, where components attached to soldered pads experience movement. Self-alignment can enhance the assembly quality by adjusting component positions near the desired position. However, it can lead to assembly defects, such as poor attachment and tombstoning, as components are shifted away from the pad center, resulting in an unbalanced position. Therefore, understanding and correctly using self-alignment becomes significant in modern electronic manufacturing. This research proposes a model that collects data from inspection to estimate the self-alignment strength and find a new placement location that can reduce component misalignment and enhance dimensional requirements for PCB assembly, such as side overhang and end overlap.
