Early lifecycle demand forecast is critical to consumer technology products with a fast innovation speed, as firms which compete on these focus timely responding market changes through new product development and efficient diffusion, rather than sustaining sales. The challenge for obtaining an accurate long-range that sales volumes at the early stages are small, limits accuracy. We propose two-...

Sellers readily obtain consumer product evaluations from online reviews in order to identify competitive products detail and predict sales. Firstly, we collect review data shopping websites, social media, communities, other platforms competitors with the help of word-frequency cooccurrence technology. We take mobile phones as an example mine analyze competition information. Then, calculate quan...

To investigate the applicability of ARIMA models in wholesale vegetable market models are built taking sales data of one perishable vegetable from Ahmedabad wholesales market in India. It is found that these models can be applied to forecast the demand with Mean Absolute Percentage Error (MAPE) in the range of 30%. This error is acceptable in fresh produce market where the demand and prices are...

In this paper we propose to apply wavelet theory in forecasting economic time series. The method consists in decomposing the series into its long-term trend and its seasonal component according to the shape of the scalogram of the discrete wavelet transform of the series. Each component is then extended to provide a forecast of the total series. The method is applied to the data set of monthly ...

Several hundred organizations are now using prediction markets to forecast sales, project completion dates, and more. This number has been doubling annually for several years. Most, however, are simple prediction markets, with one market per number forecast, and several traders per market. In contrast, a single combinatorial prediction market lets a few traders manage an entire combinatorial sp...

Exponential smoothing is often used to forecast lead-time demand for inventory control. In this paper, formulae are provided for calculating means and variances of lead-time demand for a wide variety of exponential smoothing methods. A feature of many of the formulae is that variances, as well as the means, depend on trends and seasonal effects. Thus, these formulae provide the opportunity to i...
