- ItemProspective MADM and Sensitivity Analysis of the Experts Based on Causal Layered Analysis (CLA)(Technická Univerzita v Liberci, ) Hashemkhani Zolfani, Sarfaraz; Yazdani, Morteza; Zavadskas, Edmundas Kazimieras; Hasheminasab, Hamidreza; Ekonomická fakulta“Multiple Attribute Decision Making (MADM)” is an expert based field which is working based on real data and experts’ opinions. So many studies have been doing based on MADM methods which they usually use qualitative data based on experts’ ideas. Decisions based on the experts’ opinion shall be carefully designed to cope the real problems uncertainty. This uncertainty will be even more intricate if combining the problem with the ambiguity of the future study. Prospective MADM is a future based type of MADM field which is concentrating on decision making and policy making about the future. Prospective MADM (PMADM) can have both explorative and descriptive paradigms in the studies but it will more useful to be applied for strategic planning. In this regard, experts’ role would be even more challenging because one/some possible future/futures will be partially designed based on their opinions. Future and prediction always complicates the decision environment, especially methodologies founded on experts’ judgement. Considering experts’ preferences, attitude, and background, they may be a major source of inaccurate results. Causal Layered Analysis (CLA) is well-known “Futures Studies” method which is qualitative and usually is supporting other methods such as “Backcasting” and “Scenario Planning”. CLA has a deep point of view to the subjects to support a future with all those changes which are necessary for the main goal/goals. In this study, this idea will be proposed that CLA can be added to PMADM outline to decrease the risk of unsuitable decisions for the future and for this aim a case study about energy and CO2 consumption in policy making level proposed and a hybrid MADM method based on BWM-CoCoSo applied in the PMADM outline for the procedure.
- ItemSustainability criteria assessment for life-cycle phases of petroleum refinery projects by MADM technique(Technická Univerzita v Liberci, ) Gholipour, Yaghob; Hasheminasab, Hamidreza; Kharrazi, Mohammad; Streimikis, Justas; Ekonomická fakultaPRI projects have large impacts on various sustainability attributes in different phases. A comprehensive assessment of these impacts for project’s life-cycle is of great importance. The proposed methodology has created the required framework for such assessment by using Concept Mapping, Focus Group, and Multi-Attribute Decision Making Techniques. Petroleum refinery industry (PRI) is comprised of a chain of expertise and engineering disciplines and is also connected to various other industries. Consequently, apart from its physical products that fulfill the fuel needs of the society, PRI has a great contribution to economic development and to the prosperity of different businesses. On the negative side, however, PRI is one of the primary contributors to global warming and other environmental issues and could have some unwelcome effects on the society as well. Hence, development of these projects should be done with careful assessment of their life-long impacts from a sustainability viewpoint. In this study, a sustainability framework for PRI projects, which was developed and presented in a previous publication, is used in a multiphase methodology to assess the relationship between life-cycle phases and sub-phases of a petroleum refinery on one hand, and sustainability indicators and factors on the other hand. As a result of this study, critical sustainability factors can be highlighted, to help managers and industry experts consider long-term sustainability consequences in their decision making process. The proposed methodology has been applied to a real petroleum refinery project, using an MADM-based scenario approach, to assess the correlation between sustainability factors and various life-cycle phases and sub-phases of the refinery. Based on the results, the most important phase in the petroleum refinery life-cycle with regards to all three pillars of sustainability is found to be the operation phase. As such, implementation of various operation phase sustainability aspects should be the first priority of stakeholders during design, procurement, construction, and operation phases.
