With the purpose of finding effective method in construction schemes decision-making and improving productivity level of construction enterprises, the application of simplified ELECTRE method in optimal selection of construction schemes was studied in this paper. The calculation process and main steps of simplified ELECTRE for optimal selection of construction schemes were presented here. An example of construction scheme optimal selection for shear wall template was analyzed, and the calculation progress was programmed on the platform of MATLAB 7.0. The result analysis shows that simplified ELECTRE can supply satisfactory preferential order of alternatives considering comprehensive influence of many factors. It has simple and clear sorting principle, furthermore, it is very suitable to be calculated in program, and the result is accurate and reliable. Simplified ELECTRE method is proved to be good to solve the problem of optimal selection of construction schemes.

Currently, one of the main approaches used in analyzing properties and synthesis of signals in various classes is the subband methodology, which is carried out from the position of Fourier transform of signal samples (frequency representations) into subbands of the transform definition domain  (transformants). In this case, the main tool, which is widely used for subband analysis (including wavelet analysis), is usage of bandpass filters (mainly those with finite impulse response or FIR filters). The present paper  introduces the basics of building a theory forsubband analysis / signal  synthesis for various classes, and using transformations based on any  orthonormal basis with weight. This proposed approach is based on the  concept of Euclidean signal norm square fraction in a given subband of the transformant definition domain. It is shown that the basis for mathematical apparatus of subband analysis is a new class of matrices, called subband ones. Some eigenvalue properties of these matrices are established, and the problem of optimal selection for additive signal components is formulated and solved
