Flow shop scheduling is a scheduling model in which the job to be processed entirely flows in the same product direction / path. In other words, jobs have routing work together. Scheduling problems often arise if there is n jobs to be processed on the machine m, which must be specified which must be done first and how to allocate jobs on the machine to obtain a scheduled production process. In research of Zini, H and ElBernoussi, S. (2016) NEH Heuristic and Stochastic Greedy Heuristic (SG) algorithms. This paper presents modified harmony search (HS) for flow shop scheduling problems with the aim of minimizing the maximum completion time of all jobs (makespan). To validate the proposed algorithm this computational test was performed using a sample dataset of 60 from the Taillard Benchmark. The HS algorithm is compared with two constructive heuristics of the literature namely the NEH heuristic and stochastic greedy heuristic (SG). The experimental results were obtained on average for the dataset size of 20 x 5 to 50 x 10, that the ACO-GA algorithm has a smaller makespan than the other two algorithms, but for large-size datasets the ACO-GA algorithm has a greater makespan of both algorithms with difference of 1.4 units of time.
Communication technology has become an important part of various areas of life. Because of the many conveniences offered, communication technology can hardly be separated from various aspects of human life. With the rapid development of communication technology, it has had a positive impact on society. In addition, communication technology is capable of shortening distances, saving costs, and being able to penetrate space and time. Short Message Service or better known as SMS is now widely used by the public as a communication tool. The advantages of SMS are low cost, fast and direct to the destination. Starting from children, teenagers, adults to the elderly, almost all of them take advantage of this SMS technology. Initially, SMS was only used for interpersonal communication. But now with the times, SMS users are growing. For example, for polling an audition, accessing lecture scores, sending criticism and suggestions to the mass media for publication and many other uses. To be able to do these things, of course, support from adequate software & hardware is needed
The development of information technology does not only play a role in the economic field, but also in the field of education. Today every employee at almost all levels of education is required to be technology literate, especially information technology. In addition to supporting educational activities, information technology literacy also supports teachers in solving administrative problems. Some of the software that can be used to support education and administrative issues are Microsoft Word, Microsoft Excel, and Microsoft PowerPoint. Microsoft Word, Microsoft Excel, and Microsoft PowerPoint software have many features that some users are still not familiar with. This is experienced by the Medan KPU Office employees who are not familiar with the tools that are widely provided in Microsoft Word, Microsoft Excel, and Microsoft PowerPoint software. Some of the obstacles that are often encountered are the less than optimal use of the merge function in Word, the function of conditional formulas in Excel and animation, and multimedia in PowerPoint. This is the background for the dedicated team to provide training on "Microsoft Office Training for Medan KPU Office Employees". This activity was held at the Medan KPU Office with lecture methods and direct practice.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
