Abstract— As the rapid development of science, information and technology, humans are trying to find ways to help and facilitate the completion of their work quickly and efficiently. Due to the development of the information that requires an agency or company must be able to manage it, one of which is managing a large number of company employee data, of course it will be difficult if managing a large number of employee data manually. By using information systems, it is expected to facilitate the performance of agencies or companies in managing employee data at the company quickly and accurately.PT. XYZ is a garment production company that has many employees or employees, the employees consist of various educational backgrounds, and has a variety of years of service, every year rolling employees are held routinely for promotion, moving offices or moving work divisions in the production department. and others, the employee rolling criteria are based on evaluating employee performance within a certain period of time, even to dismiss employees is also seen from their performance appraisal. Referring to the problems above, it should be developed a staffing information system and web-based performance appraisal at PT. XYZ The system built can later be operated in various regions or places using the internet network, because PT. XYZ is not only in one place but there are in some places which are quite far from its headquarters, therefore the system that is built based on the web is considered suitable with the conditions in the field. From the employment information system and web-based performance appraisal at PT. XYZ, can be used as a tool to manage employee data, work attendance, monitoring, and evaluating employee performance. Keywords—: Personnel Information System; Performance assessment; Personnel Staff.
This paper is aimed to describe the structural complexity of the traffic light control system. The structural complexity represents an interrelationship indicator between the various elements functions. The traffic light control system has several additional features that are synchronized to the railway doorstop, and the time interval for the green signals is expanded. For determining the method of its structural complexity, the Petri net model is used. Three kinds of traffic lights models are explored, namely standard, Norwegian, and the Norwegian improvement. The study results indicate that the Norwegian traffic lights have the most complex structure when regular implementation. The runner up is the Norwegian improvement. The most ideal is the standard traffic lights. Norwegian improvement is the most ideal when integrated with the railway doorstop and implemented extra green signals time interval. The Norwegian traffic light is the second. The standard traffic lights structural complexity fluctuates. It means that the Norwegian traffic light and its improvement are suitably used. Adding several features improve the structural complexity approaching the ideal system while extra controllers accompany each element. HIGHLIGHTS The Petri net model can represent the structural complexity of a system The method that can measure the structural complexity becomes ideal for actual implementation The Norwegian traffic lights structural complexities and improvements are ideal for the systems synchronized to the railway and appropriate for systems using the extra green signal time intervals or other additional features GRAPHICAL ABSTRACT
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.
