Two non-standard finite difference schemes for the Timoshenko beam
In this paper, we derive two non-standard finite difference schemes for the Timoshenko beam problem. The schemes are uniform with respect to the thickness small parameter of the beam, thus, no locking phenomenon occurs. Numerical results are presented. Key words: Timoshenko beam, non-standard difference scheme, locking phenomenon
Logistic preference function for preference ranking organization method for enrichment evaluation (PROMETHEE) decision analysis
Decision problems relate to problems of ranking, choice and detection with regards to whether a decision alternative efficient parameter satisfies some given conditions. The preference ranking organization method for enrichment evaluation (PROMETHEE) methods of decision analysis are recognized as being efficient in solving problems involving ranking. Various preference functions have been established in...
