Demand Forecasting Model of Port Critical Spare Parts
Demand forecasting for port critical spare parts (CSP) is notoriously difficult as it is expensive, lumpy and intermittent with high variability. In this paper, some influential factors which have an effect on CSP consumption were proposed according to port CSP characteristics and historical data. And analytic hierarchy process (AHP) is used to sieve out the more influential factors. Combined w...
متن کاملForecasting Models for the Cargo Throughput at Hong Kong Port and Kaohsiung Port
The import and export of goods normally require the involvement of many different sectors from purchasing, manufacturing, transporting, inventory, distribution, etc. In order to have proper plans, accurately forecast the volume of imported-exported goods is the core issue. By comparing the performance of autoregressive integrated moving average (ARIMA) model, Grey model, and their joint Fourier...
متن کاملA Verhulst Model on Time Series Error Corrected for Port Throughput Forecasting
The grey theory mainly works on systems analysis with poor, incomplete or uncertain messages. The popular grey model, GM(1,1) is efficient for long-term port throughput forecasting. However, it is imperfect when the throughput increases in the curve with S type or the increment of throughput is in the saturation stage. In this case, the throughput forecasting error of grey system model will bec...
متن کاملForecasting Container Throughput within Multi-Port Region Using CDE-MPR Methodology: the Case of PRD Region
This paper proposes a CDE-MPR methodology designed to forecast and analyze container throughput volumes. The proposed methodology includes: a container throughput module which considers both interactions among ports and other influence factors, a demand demand-oriented module which provides additional information and chance events effect had on the maritime industries. It is applied to forecast...
متن کاملA New Approach to Forecasting Container Throughput of Guangzhou Port with Domain Knowledge
Although judgmental models are widely applied in practice to alleviate the limitation of statistical models ignoring domain knowledge, they are still suffering from many kinds of biases and inconsistencies inherent in subjective judgments. Moreover, most of the prior studies are often concentrated on making judgmental adjustments to statistical projections and ignore incorporating domain knowle...
