fitting of an appropriate mathematical model to the forcasting of the manpower cost

this study is aimed at comparison of two quantitative model arima and madm in predicting manpower costs. also qualitative issue and problems of manpower planning are transformed in to qualitative one’s so as optimum planning and forecasting be made. in this study, we first used the time- series models especially arima, to fit forecasting manpower costs in shiraz hafez tile mfg. plant and extract the results. then the model was ralidated using interpolation and extrapolation statistical methods. at the next stage, madm was performed on manpower costs of the same plant and for comparing it with arima, we used the enteropy technique and at a later stage, we compared the findings of the forecasting with. arima with  the findings of the enteropy technique and for that purpose we used statistical methods, nonparametric test, spearman and kendal and test and some other tests. at last, the findings along with the computer formulae were provided in the study.
