The Mathematical Model

Based on the analysis of accidents of 500 kV over-head lines of the main electric electrical grid of a wide region over a long-time-interval, the failure frequency (failure flux parameter) was determined under the influence of natural and socio-economic factors. It is proposed to consider the indicated failure rate as the output signal of a discrete positive dynamic system with many difficult formalizable inputs. To identify the mathematical model of a dynamic system, it is proposed to use the original method, the identifiability criterion of which is based on the compatibility condition of the linear matrix equation, and the numerical identification algorithm is based on the solution formula using zero-divisors and generalized inverse matrices. The method does not require a priori information about the parameters of the mathematical model of the electric electrical grid, does not involve solving the forecasting problem, and does not apply statistical calculations

When choosing a construction company, it is important for the investor to assess its organizational and technological reliability, which affects the duration and cost of construction. It is proposed to use as a source of information about the reliability of the data on the development of capital investments by the construction organization for a fixed period of time. The purpose of the study – to offer a mechanism for assessing the organizational and technological reliability of the construction company in the construction of the Foundation. On the basis of the method of variant design all possible alternatives of simple technological processes in the construction of pile foundations were considered. Using the method of statistical testing of simulation models on each process flow, the most probable duration and cost of design work were determined. All the options for the development of capital investments were reduced to a statistical series, on the basis of which the curve of accumulated probabilities was constructed. On the curve of accumulated probabilities it is possible to determine the probability of building foundations at the right time with the required value of the index of development of capital investments. Variant design of the construction process allows to develop simulation models of construction of any foundations, on the basis of which the curves of the accumulated probabilities of the indices of development of capital investments for each type of foundations are formed. These curves serve as the basis for the investor in determining the organizational and technological reliability of construction organizations.

In the article, the author considers the problems of complex algorithmization and systematization of approaches to optimizing the work plans of construction organizations (calendar plans) using various modern tools, including, for example, evolutionary algorithms for "conscious" enumeration of options for solving a target function from an array of possible constraints for a given nomenclature. Various typical schemes for modeling the processes of distribution of labor resources between objects of the production program are given, taking into account the array of source data. This data includes the possibility of using the material and technical supply base (delivery, storage, packaging) as a temporary container for placing the labor resource in case of released capacity, quantitative and qualification composition of the initial labor resource, the properties of the construction organization as a counterparty in the contract system with the customer of construction and installation works etc. A conceptual algorithm is formed that is the basis of the software package for operational harmonization of the production program ( work plans) in accordance with the loading of production units, the released capacities of labor resources and other conditions stipulated by the model. The application of the proposed algorithm is most convenient for a set of objects, which determines the relevance of its implementation in optimization models when planning production programs of building organizations that contain several objects distributed over a time scale.

Purpose Although there are many challenges and constraints for construction organization operation and performance in a post-conflict condition, there is insufficient construction project management literature. Therefore, the purpose of this paper is to identify a framework to understand and determine critical constraints and opportunities in a post-conflict condition facing local construction firms in Afghanistan. The proposed framework is composed of three major steps: identify and determine key performance indicators; identify challenges impacting organization operation and performance in post-conflict condition; determine critical constraints and opportunities based on prioritized performance measures; and organizational strength and weakness factors. Design/methodology/approach The strength, weakness, opportunities and threat matrix analysis has been used to determine post-conflict condition constraints and opportunities. Then the analytical hierarchy process has been used to prioritize the measures and identify the constraints and opportunities facing construction companies in a post-conflict situation. The mix-research method is applied to this study to analyse qualitative variables and quantitative variables obtained from the experts’ opinions and 51 filled questioners. Findings The study shows that there are a total of 11 critical constraints and three essential opportunities for construction companies that industry practitioners and policymakers should take into account while formulating the organizational strategy. Practical implications The developed framework will benefit construction companies in improving their performance and operation in after-conflict conditions. Originality/value This paper is the first to provide a comprehensive conceptualization of the challenges and constraints for construction organization operation and performance in a post-conflict condition. It also offers a novel conceptual framework to understand and determine critical constraints and opportunities in a post-conflict condition facing local construction firms in Afghanistan.
