In this paper, the three-dimensional （3D） coupling effect is discussed for nanowire junctionless silicon-on-insulator （SOI） FinFETs. With fin width decreasing from 100 nm to 7 nm, the electric field induced by the lateral gates increases and therefore the influence of back gate on the threshold voltage weakens. For a narrow and tall fin, the lateral gates mainly control the channel and therefore the effect of back gate decreases. A simple two-dimensional （2D） potential model is proposed for the subthreshold region of junctionless SO1 FinFET. TCAD simulations validate our model. It can be used to extract the threshold voltage and doping concentration. In addition, the tuning of back gate on the threshold voltage can be predicted.

Due to the extensive applications of the flowshop sequence-dependent group scheduling problem（FSDGSP）, especially in the manufacturing industry, there has been a growing interest in the research of it. In this paper, a constructive heuristic called JPALRxis proposed for solving FSDGSP with total flow time criterion. In the JPALRx, a sequence of part families is determined by a jigsaw puzzle inspired algorithm considering major family setup times. Afterwards, a job sequence within each part family is obtained by using a heuristic algorithm called LRx. Furthermore, an insert operator based on family is used to further improve the quality of the solution obtained. The experimental results demonstrate the effectiveness and efficiency of JPALRx.

Distributed permutation flowshop group scheduling problem(DPFGSP) is studied in this paper. This problem can be regarded as a combination of the distributed flowshop scheduling and group scheduling. An improved iterated local search(dILS)algorithm is proposed to minimize the total flowtime. First of all, we use a simple heuristic algorithm based on the famous NEH heuristics to generate an initial solution. Next, we use the solutions obtained from two different neighborhoods to perform an iterated local search. The acceptance criterion is the simulated-annealing type with a constant temperature. Finally, the proposed dILS algorithm is compared with the existing VND algorithm based on the 810 benchmark instances. The experimental results show that the proposed dILS algorithm has significant advantages in solving the DPFGSP under consideration.
