The method of analyzing data known as Discrete Mathematical Analysis (DMA) incorporates fuzzy mathematics and logic. This paper focuses on applying DMA to study the morphology time series by utilizing language mathematics. morphological characteristics series, such background, slopes, vertices, are considered sets within domain its definition. allows for use logic in examining ultimately leadin...

Many traditional time series model has been widely applied in forecasting Problem. However, the previous time series methods still have some constraints: (1) conventional time series models only considered single variable; (2) traditional fuzzy time series model determined the interval length of linguistic value subjectively; (3) selecting variables depended on personal experience and opinion. ...

Konsumsi minyak dan gas (migas) Non-migas di dalam negeri dari waktu ke terus meningkat. Peningkatan ini tidak bisa dipenuhi hasil produksi migas negeri. Akibatnya, Indonesia yang dulu dikenal sebagai kaya kini harus rutin mengimpor luar Pada penelitian ini, digunakan salah satu metode untuk melakukan prediksi atau peramalan yakni Fuzzy Time Series Cheng. Data aktual adalah Peramalan Import Mig...

E-mail address: jose-luis.aznarte@mines-paristech In general, times series forecasting is considered as a highly complex problem, which is particularly true for financial time series. In this paper, a fuzzy model evolved through a bio-inspired algorithm is proposed to produce a...
