| Abstract: | A new calculating model for the average daily air temperature is proposed, With possi-ble sudden change of temperature in a month taken into consideration, three traditional cal-culating models are obtained by least square fitting of observed data of average daily air tem-perature of three years. They are one harmonic term and four harmonic terms trigonometricseries and a polynomial of degree 3. The 3 years observed data is specified as a fixed modeland the data of each of the three years is specified as one of another three models.Accordingto the fuzzy set theory, five similarity factors, the average annual temperature,averagemonthly temperature, temperature distribution in every month, the number of days the heatpump operates for refrigeration and the number of days the heat pump operates for heating,are used to compare and assess the similarities between every model and the fixed one, Theorder of priority of these models is determined with the fuzzy optimum seeking method. |
