İş süreçlerinin modellenmesinde gert şebekelerinin kullanımı

Son yıllarda işletmeler, artan bilgi ihtiyacını karşılamak amacıyla çok çeşitli ve karmaşık iş süreçleri kullanmak zorunda kalmışlardır. İş süreçlerinin firma performansı ve kârlılığı üzerindeki etkisinin anlaşılması ile beraber, akademisyenler ve yöneticiler bu süreçlerin çok yakından incelenmesi ve analiz edilmesi ihtiyacını gündeme taşımışlardır. Kendi aralarındaki bütünleşme zorunluluğu da düşünüldüğünde iş süreçlerinin modellenmesi ve analiz edilmesinde gelişmiş sistemlerin kullanılması kaçınılmaz olmuştur. Bu sistemlerin kullanılması ise bir yazılım desteğinin alınmasını ve bu yazılımı kullanacak personelin eğitilmesini gerektirmektedir. Mevcut veya yeniden tasarlanan iş süreçlerinin modellenmesi ve analizinde, hâlihazırdaki uygulamalara katkı sağlayacağı düşünülen bu çalışmada stokastik şebeke çözümlemesinde kullanılan bir teknik olan GERT’in (Graphical Evaluation and Review Technique) analitik hesaplama yeteneğinden faydalanılarak örnek bir iş süreci modellenmiş ve zamana dayalı analizlerinin yapılabileceği gösterilmiştir.

Using gert networks in business process modeling

Recent years, Firms have to use various and complex business processes for providing knowledge needs that is becoming increased. With understanding impact of the business processes on performance and profitableness of the firms, many academicians and managers need to get closer these business processes. With integrating needs between each process, it is inevitable to use improved systems for modeling and analyzing these business processes. For using these systems, it is necessary to be supported software and to be trained for using this software. In this work, as a stochastic network solution, GERT (Graphical Evaluation and Review Technique) is used to model and analysis as-is and to-be processes. An example business process is modeled and analyzed by using GERT and its analytical calculation ability.
