SCENARIO APPROACH TO EFFICIENCY ASSESSMENT OF MAIN OIL PIPELINE CONSTRUCTION INVESTMENT PROJECT

assessment of the efficiency of s.p.g.c refineries using network dea

data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...

Systems Analysis of Investment Project Efficiency Evaluation

Knowledge-Oriented Approach to the Main Pipeline Complex Dispatching Control

The article is devoted to the development of knowledge-oriented models that are able to increase the efficiency and quality of main pipeline complex (MPC) dispatching control. The main attention is paid to the dispatching control of electrochemical protection (ECP) of pipelines from corrosion. Functional knowledge-oriented model that is created on the basis of typical intelligent blocks is prop...

A fuzzy group decision making approach to construction project risk management

Implementation of the risk management concepts into construction practice may enhance the performance of project by taking appropriate response actions against identified risks. This research proposes a multi-criteria group decision making approach for the evaluation of different alternative response scenarios. To take into account the uncertainties inherent in evaluation process, fuzzy logic i...
