Ανάδειξη κρίσιμων κωδικών για την λειτουργία μέσω ABC Ανάλυσης με βάση το κριτήριο της ετήσιας ανάλωσης και ως προς το κριτήριο της ετήσιας αξίας ζήτησης. Στη συνέχεια αναπτύχθηκε σύστημα πρόγνωσης της ζήτησης με βάση της μεθόδου εξομάλυνσης και κυρίως με βάση της μεθόδου του κινητού μέσου όρου και της της απλής εκθετικής εξομάλυνσης. Τέλος αναπτύχθηκε πρόταση συστήματος διαχείρησης αποθεμάτων με βάση τα αποτελέσματα της ετήσιας προγνωσθήσας ζήτησης.
The present dissertation was carried out aiming at the development of the forecast of demand in the import and trade company of industrial hydraulic equipment. First there was the process of classification based on the criteria of the annual value of usage and annual value of demand. Later the codes were graded based on the imports value as well as the average stock value, so that it could be checked whether codes with a high gathering in deposit are kept.
The codes which proved to be critical according to the classification based on the annual value of the demand were used so that that the model of forecast could be developed. For the smoothing of the demand data the models of the simple moving average, the simple exponential smoothing, the model of the double exponential smoothing, the exponential smoothing adapted to the trend and the exponential smoothing adapted to the trend and the seasonal demand were used.
Finally, regarding those codes as well as the prices of the demand per year which will arise, will calculate the optimal reorder portions and frequency of orders.
