The objective of this study was to model seasonal behavior of broiler price in Iran that can be used to forecast the monthly broiler prices. In this context, the periodic autoregressive (PAR), the seasonal integrated models, and the Box-Jenkins (SARIMA) models were used as the primary nominates for the forecasting model. It was shown that the PAR (q) model could not be considered as an appropri...

Periodic time series analysis refers to the modelling approach where important time series properties depend on the period of the year. The standard approach to time series modelling is to treat a time series as a stochastic process with seasonal fluctuations. In a periodic analysis seasonal variations are modelled using separate yearly time series for each season, which do not possess seasonal...

Fuzzy time series forecasting methods has got more and more attention in recent years since they have a good capability of forecasting real-world time series which contains uncertainty. There have been various fuzzy time series forecasting methods in the literature. On the other hand, just a few ones have been proposed to forecast seasonal time series. When a seasonal time series is forecasted,...

The planning of production capacity for a company has been extensively discussed in literature. Seasonal demand of products or seasonal availability of input materials can make the problem even more challenging, as due to a constant need for capacity adjustments. For example, in contrast to conventional chemical processes, the use of biomass has several distinct characteristics like a time depe...

BACKGROUND In Lithuania, suicides are a grave public health problem, requiring more extensive investigation. The aim of the study was to assess the seasonal variations of suicides in Lithuania throughout the years 1993-2002, describing patterns by gender, age and method of suicide. METHODS The study material consisted of all registered suicides (n = 16,147) committed throughout 1993-2002 in L...
