Therefor finding dominant factors of detect variable of stock problems are very important. The dominant factors is found by literature study then be equipped by historical data of annual periods. Statistical Pearson correlation and multi-pexpert multi-criteria decision making (MEMCDM) non-numerical are used to test and to verify correlation the dominant factors of national crude palm oil stock, and then fuzzy system is used to judge the dominant factors.
