First-Order Fuzzy Time Series based on Frequency Density Partitioning for Forecasting Production of Petroleum

Abstract: Forecasting method based on fuzzy time series has been widely developed in recent years. In this paper, we propose a new improvement at determining universe of discourse, variation historical data and partitioning stage. At early stage, we define the universe of discourse then calculate the basis value to find out how much interval should be used with variatin historical data. Secondly, we are partitioning the main intervals into several numbers of sub-intervals. The empirical analysis shows that sub-interval … Show more

“…the adjustment value is obtained, then the final forecast value. For the calculation of the adjusted forecast value, follow the existing rules in equation (21). For example, calculations for adjusted forecast values F ′ 2 = F 2 ± D t2 = 180:17 + 0:25 = 180:42; by doing the same way, the summary of the final forecasting results is shown in Table 7.…”

“…Singh [34] reviewed prior research in the FTS field and recognized domain-specific difficulties and research trends, and attempted to classify them with implications for future study. Wulandari, Surarso [35] provided a new advancement in establishing the UoD, historical data variation, and partitioning stage. They tried to define the UoD for computing the base value to determine how many intervals should be employed.…”

“…For several decades the modification of fuzzy time series forecasting has developed rapidly to find the best method with a better error forecast. In the first basic step of defining the universe of discourse, Chen et all define how to find the range of intervals for the universe of discourse [8], still, at the same step, Jilani et al proposed dividing Chen's interval into several sub-intervals using frequency density partitions, like has been studied by B Irawanto et al with a modification of the metric approach for predicting fuzzy time series based on frequency density partitions [8]- [10]. The second basic step is to build a triangular fuzzy number using the definition of Kusuma et al [11].…”
