The increase of electric power demand and cost of generation, make forecasting very economical to the supply authority and useful to reduce uncertainty to the consumer. Out of various forecasting models, Box-Jenkins time-series models are useful but costly to operate. Modified BJ model, having lot of advantages, were developed for long range forecast of electrical load and a frequency domain ap...

We propose simulation-based forecasting methods for the noncausal vector autoregressive model proposed by Lanne and Saikkonen (2012). Simulation or numerical methods are required because the prediction problem is generally nonlinear and, therefore, its analytical solution is not available. It turns out that different special cases of the model call for different simulation procedures. Simulatio...

Long-term demand forecasting presents the first step in planning and developing future generation, transmission and distribution facilities. One of the primary tasks of an electric utility accurately predicts load demand requirements at all times, especially for long-term. Based on the outcome of such forecasts, utilities coordinate their resources to meet the forecasted demand using a least-co...

In recent years, BTO (Build to Order) system is prevailing. It pursues short lead time, minimum stocks, and thereby minimum cost. But the high accuracy demand forecasting is inevitable for the parts manufacturers. In this paper, well organized BTO system in the sanitary materials manufacturer is seek with the aid of high accuracy demand forecasting, which is newly developed by us. Focusing that...

In this paper, we provide an analytical perspective on the link between supply chain collaboration and forecast accuracy, showing that collaborative forecasting can lead to less accurate demand forecasts over a wide range of cost and demand parameters. The result is explained by the decision maker’s relative preference for investing in forecasting vs. order quantities to manage demand uncertain...

<p><span>Industrial reports show massive cost overruns associated with software projects. The of reworks constitutes a large portion the overall cost, reflecting substantial challenge in control. Earned value management (EVM) is most recognized model for project However, it shows many limitations forecasting leading to considerable Nevertheless, major EVM limitation found its inabil...

Load forecasting is an important problem in the operation and planning of electrical power generation. To minimize the operating cost, electric supplier will use forecasted load to control the number of running generator unit. Short-term load forecasting (STLF) is for hour to hour forecasting and important to daily maintaining of power plant. Most important factors in load forecasting includes ...
