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 Intermittent Demand for Spare Parts
Croston (1972) [2] presented an idea and method to separate ordinary exponential smoothing in two parts;In the time between demand, or withdrawals, and demand size. The idea with the modification in Levén and Segerstedt (2004) [3] is that time between demand and demand size is not independent. But this modification has shown poor results. Therefore Wallström and Segerstedt (2010) [8] suggest an...
متن کاملModelling Spare Parts' Demand: an Empirical Investigation
Intermittent demand patterns are very difficult to forecast and they are, most commonly, associated with spare parts’ requirements. Most research in this area focuses on the control of inventories assuming that an appropriate estimator is in place to forecast demand and that the demand is represented by one of the standard statistical distributions. The choice of a demand distribution has an im...
متن کاملBayesian Forecasting of Parts Demand
As supply chains for high technology products increase in complexity, and as the performance expected of those supply chains also increases, forecasts of parts demand have become indispensable to effective operations management in these markets. Unfortunately, rapid technological change and an abundance of product configurations mean that demand for parts in high-tech is frequently volatile and...
متن کاملSpare parts classification and demand forecasting for stock control: Investigating the gap between research and practice
This paper investigates the gap between research and practice in spare parts management, with specific reference to durable goods addressed to private or professional customers. The paper provides a critical literature review of theoretical contributions about spare parts classification and demand forecasting for stock control. The discussion of ten case studies, then, allows to analyze the rea...
