The optimal SRAP-PCR system for Lonicera caerulea L. was 20 ktL SRAP-PCR amplification reaction solution containing 2.0 μL 10×PCR buffer, 1.0 U Taq DNA polymerase, 30 ng template DNA, 0.2 mmol·L-1 dNTPs, 2.0 mmol·L-1 Mg2＋ and 0.2μmol·L-1 primer. The suitable amplification procedure consisted of an initial denaturation at 94℃ for 5 min; denaturation at 94℃ for 1 min, annealing at 35℃ for 1 rain, extension at 72℃ for 90 s and in total five cycles; denaturation at 94℃ for 1 min, annealing at 50℃ for 1 min, extension at 72℃ for 90 s and in total 35 cycles; extension at 72℃ for 8 rain; preservation at 4℃. The procedures and systems could meet the demand for SRAP amplification of Lonicera caerulea L. and would play an important role in Lonicera caerulea L. germplasm identification and genetic diversity analysis.展开更多

With the development of manufacturing technology, we can probe a new way to solve this problem. Firstly, a new method for task granularity quantitative analysis is put forward, which can precisely evaluate the task granularity of complex product cooperation workflow in the integrated manufacturing system, on the above basis; this method is used to guide the coarse-grained task decomposition and recombine the subtasks with low cohesion coefficient. Then, a multi-objective optimieation model and an algorithm are set up for the scheduling optimization of task scheduling. Finally, the application feasibility of the model and algorithm is ultimately validated through an application case study.展开更多

First of all, by replacing parallel jobs with virtual jobs, the proposed algorithm converts the serial-parallel system into a pure serial system, where the classical Hungarian algorithm can be used to generate a temporal assignment plan via optimization. Afterwards, the assignment plan is validated by checking whether the virtual jobs can be realized by real jobs through local searching. If the assignment plan is not valid, the converted system will be adapted by adjusting the parameters of virtual jobs, and then be optimized again. Through iterative searching, the valid optimal assignment plan can eventually be obtained.To evaluate the proposed algorithm, the valid optimal assignment plan is applied to labor allocation of a manufacturing system which is a typical serial-parallel system.展开更多
