“…The Analytical Hierarchy Process (AHP) is a technique developed by Professor Thomas L. Saaty in (1980) as a Multi Criteria Decision Making tool, where inputs can be obtained through personal opinion such as satisfaction, or through actual measurements such as price and weight [16][17][18][19]. The main vectors are called priority vectors.…”

The views at the construction field emboss that construction parties are looking for a higher benefit during implementing aspects of any project. The feasibility study is one of the serious and significant matters in construction sectors as well as in other engineering fields as it has a high impact on investment decision-making. To gain rigorous decisions from decision-makers or contractual parties (client, consultant, and contractor), there is a need for valuable feasibility studies in any construction project. This paper aims to study the influence of some identified factors on feasibility studies as well as the extents of priorities of various feasibility studies. In this paper, the critical factors that have an impact on sequences of initial feasibility studies during the lifecycle of a construction project were identified as well as the associated studies (legal, environment, marketing, technical, managerial, schedule, financial and economic). In this study, 12 factors were identified, analyzed, and thoroughly discussed to have recommendations of their impact on initial feasibility in construction projects in Iraq via a questionnaire survey and a series of expert interviews conducted in Iraq. The Analytical Hierarchy Process (AHP) as a multi-criteria decision support system was adopted to examine the weight of each factor. In addition, an analysis by the Relative Importance Index (RII) was carried out to rank eight types of feasibility studies in terms of their perceived importance. The results of AHP indicated that the local shortage of database about the feasibility study was the most critical factor. Indeed, RII's result showed that all kinds of feasibility for construction projects in Iraq are not adopted by the client. In fact, the economic feasibility study was the most popular than others.

“…However, it should be borne in mind that the intangible assets development requires significant investments and is inherently innovative, therefore it is important to take into account the management process risks [1] related to the intangible assets formation, as well as both operational and strategic development and improvement planning optimization. There are traditional approaches in economic science and practical activity as to using optimization methods for modelling many economic processes [17]. V. Andriienko, I. Ivchenko, Z. Sokolovska, A. Yepifanov and many other scientists consider the problems of econometric and mathematical modelling wide use in the study of complex economic systems and processes associated with real (tangible) assets [8], [19].…”

The economic fundamentals of intangible assets topicality, their development in the context of targeted operational and strategic planning of enterprises' activities are described. The scientific and methodical approach was proposed to constructing a linear function of the enterprise's intangible assets improvement and development plan, to estimating of the linear function plan adequacy to the input data, to determining of the optimal plan for a given set of factor characteristics, and to determining of the plan indicators' reference values. The method of assessing the effectiveness of the enterprise's intangible assets improvement and development plan is elaborated, which provides an opportunity to take into account all changes taking place in its informational-economic, intellectual, financial and organizational spheres.

The usage relevance of linear observation models of welding processes is substantiated. A brief analytical review of scientific papers on using linear observation models for researching the processes of arc welding is introduced. An example of studies utilizing a linear observation model based on the results of experiments with alloying of a weld metal is given. The type of linear observation modelfractional replicationis determined. An experiment planning matrix and test results are given. After performing tests and processing the experimental data, mathematical models in the form of dependencies of the transfer of alloying elements into the weld metal were obtained. According to the results of the experiments, empirical models in the form of dependencies evaluating the percentages of manganese, silicon and carbon, transfer coefficients from the "wire-to-product" distance, the diameter of the welding nozzle and the filling wire feed rate were obtained. Since the degree of uncertainty of parameters during welding is high enough, the necessity of further modification of linear observation models using expert knowledge is justified. The mathematical specification of the linear observation model with parameters in the form of fuzzy intervals is given. An algorithm for identifying the parameters of a linear observation model in the form of fuzzy intervals has been developed.
