Value analysis/value engineering (VA/VE) is a well-known method of technical and economic study of systems since the middle of the 20th century aimed at setting objectives to reduce the cost and functional performance of a system. Despite the widespread and successful utilisation of VA/VE, it has a number of guideline shortcomings related not only to the complexity of estimating the value of the system elements, but also to the uncertainty of unambiguous division of functions by these elements. In addition, the idea of VA/VE actually based on the principles of analysing the dissonance of system parameters can often be applied without relying on the functions of system elements. The Operation Principal Evolution with Cost-Value Analysis (OPECVA) methodology was developed to address these and other shortcomings of VA/VE: among other things, it utilises the Saaty's pairwise comparison method to compare the elements of a system in terms of certain parameters. The OPECVA methodology was implemented in the Compinno-TRIZ software package. The paper describes three types of OPECVA: OPECVA of objects and structures, OPECVA of functions and OPECVA of processes. The OPECVA of flows is reduced to the OPECVA of objects or the OPECVA of processes.
