This paper addresses the permutation flowshop scheduling problem with peak power consumption constraints (PFSPP). The real-time power consumption of the PFSPP cannot exceed a given peak power at any time. First, a mathematical model is established to describe the concerned problem. The sequence of operations is taken as a solution and the characteristics of solutions are analyzed. Based on the problem characteristics, eight heuristics are proposed, including balanced machine-job decoding method, balanced machine-job insert method, balanced job-machine insert method, balanced machine-job group insert method, balanced job-machine group insert method, greedy algorithm, beam search algorithm, and improved beam search algorithm. Similarly, the canonical artificial bee colony algorithm and iterated local search algorithm are modified based on the problem characteristics to solve the PFSPP. A large number of experiments are carried out to evaluate the performance of new proposed heuristics and metaheuristics. The results and discussion show that the proposed heuristics and metaheuristics perform well in solving the PFSPP.

Since 1980's, all the developed countries have built up national computer network of education and scientific network, which have been the most important infrastructure of education and scientific research in these countries and facilitate their development. China began to invest in building Cernet (China Education and Research Network) since 1994.Many colleges and universities have set up their own campus network. Liaocheng University set up their own campus network in 1997. In order to ensure high availability, high stability and high security of campus network, network information center staff conducted a lot of practice to explore, finally we find some way for Liaocheng University.

With the popularity of the Internet and the rise of mobile Internet application, the Internet finance is growing rapidly. The Internet finance includes online shopping, mobile payment, online financial management etc. However, there exists security problems in third-party payment, online shopping, online banking, mobile payment, etc. In order to solve the security problems with Internet finance, on the one hand, government should establish and perfect law and regulation systems, standardize network security technology, strengthen the network supervision, and make more effort to crack down Internet crimes; on the other hand, Internet users need to enhance network security awareness, and network security researchers should provide methods and countermeasures to prevent the online frauds.
