The paper examines the effective utilization of a range of methods such as Analytic Hierarchy Process (AHP), Fuzzy Analytic Hierarchy Process (FAHP), Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS), Elimination Et Choix Traduisant la Realité (ELECTRE), and VlseKriterijumska Optimizacija I Kompromisno Resenje (VIKOR) in the context of sustainability. The advantages and limitations of each method are discussed, and a comparative analysis of their effectiveness in decision-making for sustainable development is provided. Furthermore, the research paper delves into specific areas of sustainability, including construction, business, finance, accounting, industry, site selection, renewable energy, water resource management, water quality management, agriculture, and material selection. In addition, the paper highlights the importance of using hybrid MCDM methods in promoting sustainable development, which combines the strengths of different decision-making methods to provide more accurate and robust results. The overall aim of this research paper is to provide a comprehensive understanding of the different areas of sustainability and how MCDM methods can be utilized to achieve sustainable development. The study intends to contribute to the development of effective decision-making frameworks for sustainable development, providing insights for policymakers, researchers, and practitioners in the field of sustainability
EIA is a process used to identify and evaluate the potential environmental impacts of proposed projects or developments. It began in the late 1960s and has since spread to over 100 countries. The goal of EIA is to inform decision-making and promote sustainable development. It examines a project's environmental, social, health, and economic effects to improve design, mitigate impacts, and facilitate sustainable choices. While EIA initially focused on biophysical impacts, the trend is toward more integrated assessments. Sustainable development and EIA aim to meet needs without compromising future generations by reducing environmental burdens from development.
A consistent method to determine flexible criteria weightsarmankoopal
This document discusses methods for determining criteria weights in multi-criteria transport project evaluation. It introduces the Analytic Hierarchy Process (AHP) as a method that derives criteria weights from decision makers' subjective judgments through pairwise comparisons. AHP uses the principal eigenvector of the positive pairwise comparison matrix to obtain the criteria weights. While subjective approaches allow flexibility, they can also be time-consuming and inconsistent between decision makers. The document proposes using a proportion-based method that provides both consistency through its algorithm and flexibility by incorporating input from decision makers and the public.

In addressing various policy problems, deciding which policy measure to start with given the range of measures available is challenging and essentially involves a process of ranking the alternatives, commonly done using multicriteria decision analysis (MCDA) techniques. In this paper a new methodology for analysis and ranking of policy measures is introduced which combines network analysis and MCDA tools. This methodology not only considers the internal properties of the measures but also their interactions with other potential measures. Consideration of such interactions provides additional insights into the process of policy formulation and can help domain experts and policy makers to better assess the policy measures and to understand the complexities involved. This new methodology is applied in this paper to the formulation of a policy to increase walking and cycling.

SEA is a process used to evaluate the environmental impacts of policies, plans, and programs early in decision making. It can identify sustainable alternatives and prevent costly mistakes compared to project-level environmental impact assessments. The benefits of SEA include cheaper and more effective assessments, identifying options to facilitate sustainable development, and improving governance. SEA can be applied to infrastructure planning at various levels and sectors. Government agencies are typically responsible for conducting SEA to inform infrastructure planning. The document provides examples of SEA application in Myanmar and Mongolia.
A virtual environment for formulation of policy packagesAraz Taeihagh
The interdependence and complexity of socio-technical systems and availability of a wide variety of policy measures to address policy problems make the process of policy formulation difficult. In order to formulate sustainable and efficient transport policies, development of new tools and techniques is necessary. One of the approaches gaining ground is policy packaging, which shifts focus from implementation of individual policy measures to implementation of combinations of measures with the aim of increasing efficiency and effectiveness of policy interventions by increasing synergies and reducing potential contradictions among policy measures. In this paper, we describe the development of a virtual environment for the exploration and analysis of different configurations of policy measures in order to build policy packages. By developing systematic approaches it is possible to examine more alternatives at a greater depth, decrease the time required for the overall analysis, provide real-time assessment and feedback on the effect of changes in the configurations, and ultimately form more effective policies. The results from this research demonstrate the usefulness of computational approaches in addressing the complexity inherent in the formulation of policy packages. This new approach has been applied to the formulation of policies to advance sustainable transportation.
This document discusses using Multiple Criteria Decision Analysis (MCDA) to help companies select countries for new business ventures.

This document discusses the Americanization of Puerto Rico after the Spanish-American War of 1898. While Puerto Ricans initially welcomed the U.S. as liberators from Spanish rule, hoping for self-governance and democracy, they were ultimately disappointed. Puerto Rico became a U.S. territory without full political rights or self-determination. Later works suggest citizenship was granted conditionally to exert leverage over other territories like the Philippines, not out of respect for Puerto Rican autonomy. Overall, the takeover introduced cultural and economic changes but failed to deliver the political freedoms Puerto Ricans had envisioned.

The passage discusses the era of Reconstruction in America between 1860-1877 following the Civil War. This was a time of significant societal and constitutional changes, including the establishment of the Freedmen's Bureau to help formerly enslaved people and the ratification of the 14th Amendment guaranteeing equal rights. There were debates around the extent of federal government power versus state sovereignty in establishing laws during Reconstruction, particularly regarding issues of racial equality and black suffrage. The question of whether the federal government had the constitutional authority to determine laws not explicitly stated in the Constitution was a central point of conflict during this period.

Abstract (Importance)
The multi criteria analysis (MCA) is a technique being widely used to reach a decision among
various alternatives. This method is extensively used in advance countries for policy making,
feasibility & implementation of mega projects, resource allocation, making choice among
alternatives etc. It is considered an important subject and is being taught at various schools and
universities across the globe. Many universities of different countries offer admissions/courses and
hundreds of research papers have been published so far over the topic under discussion.

Introduction
MCA is a tool being widely used which helps in decision making among various alternatives.
Particularly it is used for sustainability assessment where issues of different nature like social,
political, financial etc. are taken into account. It provides a structure which is easy, simple and user
friendly for decision making.
MCA is applicable to all levels of decision making ranging from project having various alternatives
to policy making decision where MCA aids in providing a transparent and convenient structure to
reach a sustainable and wise decision. [1]
Advantages of MCA over other informal judgments [2]
• The choice of various criteria is open to decision makers and is liable to changes in case it is
not appropriate.
• The measurement of performance can be sublet (outsourced) and expert opinion may be
sought if deemed necessary. Thus it is not left merely in the hands of decision makers.
• It may be an important source of communication within decision making body and/or at later
stage between decision making body and community.
• The weights assigned to various criteria provide a track/route for audit.
Assigning scores and weights
Scores. Each option is assigned a numerical value/score on the basis of preferences which indicates
its strength. The higher the value the most preferred is the option and vice versa. For example if the
assigned value ranges from 0 to 10, then 0 indicates the least preferred option while 10 indicates the
most preferred option.
Weight. Each criterion is assigned a numerical weight on the basis of which it is assessed.

Literature Review/Discussion
Concept of Sustainable development [3]
The idea of sustainability was first floated in1972 at UN conference on human environment. An
agreement was made between 113 countries on making the environment the clear and bringing the
environment related issues to a platform for discussion and subsequent resolution. However the third
world countries had serious reservations regarding the stoppage of their development. Eventually a
world commission was established by UN in 1983 on environment and development in order to
resolve the conflict between developed and under developed countries. The commission generated a
report namely, “our common future” (Bruntland report 1987). Later on four principles were derived
from Bruntland report by Newman and Kenworthy in 1999 which are as follows.
1. To eliminate poverty especially in under developed countries. This is not limited to humans
only but environment as well. The rapid growth in human population is mainly dependent on
Agriculture and in absence of social and sustainable development there will be serious threat
to environment.
2. The developed countries should maintain a balance between resources consumption and
related waste production. On an average, a developed country consumes about 500 times
more natural resources as compared to a poor country. In order to achieve a sustainable
development, social and economic change is inevitable.
3. For success it is highly essential that all nations must work together to overcome the
environmental challenges like Green-house gases and other hazardous wastes etc. it is
pertinent to mention that globalism is the indicator to sustainable development.
4. The aforementioned changes can only occur when local communities commit to resolve their
issues. Sustainability can be implemented when there is development in local cultures.
The commission in the Bruntland report states that the environmental issues are related to the gap
between poverty (of third world) and imbalance of consumption and production (of first world).
There are many definitions of sustainable development; however the essence is the same i.e. to
provide the basic human needs in such a way as not to have violation of nature on earth.
Multi Criteria Analysis (MCA)
Suppose there is a situation where a decision has to be made regarding any issue,
there are ways to formulate and help in reaching a decision. The first thing is to set a
goal. The next step is to think about the alternatives and the key factors of relative
importance. (Belton and Stewart 2002).
[3] CHALMERS, MCA for assessing sustainability of Remedial Actions, PETRA BRINKHOFF
6. Page 6 of 15
Now there are different ways to evaluate how alternatives meet the objective. One technique is cost
benefit analysis (CBA) which is purely monetary. Another way is use of multi criteria analysis
(MCA) or multi criteria decision analysis (MCDA) which will aid in reaching a transparent and
sensible decision where the alternatives that meet the objective in a best way is sorted out.
(CLG 2009)
Outline of the MCA methodology [4]
It is a technique which makes the decision process more clear and transparent especially when there
is large amount of complex information. It may be used for different purposes like
1. To know about an option which is most preferred
2. The various alternatives are ranked against each other
3. Various alternatives are short listed
4. To differentiate between alternatives which are acceptable and not acceptable.
According to CLG (2009), MCA has the following advantages over other informal judgments.
• It is clear and specific.
• The choice of various criteria is open to decision makers and is liable to changes in case it is
not appropriate.
• The measurement of performance can be sublet (outsourced) and expert opinion may be
sought if deemed necessary. Thus it is not left merely in the hands of decision makers.
• It may be an important source of communication within decision making body and/or at later
stage between decision making body and community.
• The weightages assigned to various criteria provide a track/route for audit.
For important projects it is mandatory to get expert opinion from concerned professionals and to
have regular review of the procedure being followed.
An MCDA involves 8 steps given below. For simple decisions one can follow only step 1 to step 4
and 7 for analysis purpose which is referred to as MCA. It is pertinent to mention that MCA ends
with a performance matrix whereas MCDA analysis includes scores, weights and their combinations.
Below are given total of 8 steps wherein MCDA has been segregated by the boldface words (CLG,
2009).
1. Establish the goal, aims of MCA, decision makers etc.
2. Identify the alternatives
[4] CHALMERS, MCA for assessing sustainability of Remedial Actions, PETRA BRINKHOFF
7. Page 7 of 15
3. Establish the criteria/priorities that reflect the value associated with each alternative.
4. The performance of each alternative is evaluated/described against the criterion. If steps 5 &
6 are included, this performance is measured quantitatively by scores or other units.
5. Assign weights & scores for each of the criterion to reflect its importance with respect
to decision.
6. Combine weights and scores to get an overall value.
7. Examine the result.
8. Make a sensitivity analysis of the results to change in scores and weights.
Techniques developed for MCA.
Different techniques have been developed for MCA at different levels. Below are given the main
approaches.
• Multi Attribute Utility (MAUT)
• Outranking Approaches
• Analytical Hierarchy Process (AHP)
All the above techniques involve assigning values for alternatives, multiplying with weights and
getting a total end score. Final selection is based on situation in which an analysis is required.
Multi Attribute Utility (MAUT)
This technique was developed by the work of Neumann and Morgenstern (1944) and later by Savage
(1954). It is based on the assumption that stakeholders rationally choose among various alternatives
and aim to maximize the value of their choice. This approach also assumes perfect knowledge and
consistent judgments on part of the participants. (Linkov et al. 2005)
Outranking Approach
It is quite different approach as compared to other MCA procedures. It is more interactive process
between model and decision makers. This method was developed in France and is mostly used in
some continental European countries. (CLG, 2009)
This technique is based on outranking relation on the set of alternatives. (Belton and Stewart 2002)
There are several outranking methods like,
• Elimination et Choix Traduisant 1a Realite ELECTRE I,II,III,IV and TRI
• PROMETHEE (with or without GAIA, Geometric Analysis for Interactive Aid)
8. Page 8 of 15
ELECTRE I was developed by Roy in 1960s. The PROMETHEE method was developed by Brans
and co-workers in 1980s.
The outranking technique is applicable to both qualitative and quantitative data.
Analytical Hierarchy Process (AHP)
This method was developed by Prof. Saaty who is known as the Architect of AHP. This procedure is
considered to be the most appropriate technique for evaluating humanitarian, environmental and
engineering projects.
The AHP is decision making technique which is based on pair-wise comparison between criteria and
associated weights. It facilitates the decision making process and help the decision makers to reach
the best decision through a formal and transparent process.
The AHP procedure has the following three steps. [5]
1. The construction of hierarchy
2. Getting data to have pair-wise comparison
3. Synthesis of priorities (Harkar and Vargas 1987)
The first step i.e. construction of hierarchy is based on past experience and studies. The proposed
problem should be structured into decision making process by the participants, however every
participant may not necessarily agree on each and every point of the problem (Saaty & Kearns 1985)
All the important elements related to the problem must be covered within the process of hierarchy.
After hierarchy has been developed, the data is collected in order to have the pair-wise comparison
and the associated relative importance of each element. The priorities are set by decision makers.
The evaluation of the alternatives and criteria is either done by an individual or group involved in the
process of decision making (Crouch and Ritchie 2005).
It is pertinent to mention that when 2 elements are compared at the same time, then it will
significantly reduce the complexity involved in the process. This simplification led to the assumption
which was considered reasonable by Saaty and others.

Applications of AHP [6]
Being extensively used, AHP has much more applications in various sectors and also to human
judgment process (Lee et al. 2001). The AHP can be applied but not limited to the following
decision situations.
• To choose an alternative from among given set of alternatives.
• To rank alternatives from best preferred to least preferred.
• To allocate resources among various set of alternatives.
• To deal with the quality management system within organization.
• To settle disputes among parties having incompatible goals.
The AHP has been applied to thousands of complex decision situations so far and have produced
extensive results as regards planning, quality management, engineering, resource allocation etc.
whereas many AHP applications have not been reported due to security and privacy constraints.
Below are given some uses of AHP
• Selecting type of nuclear reactor
• Risk assessment in managing/operating cross country petroleum pipelines (ASCE)
• Deciding location of offshore plants
• Feasibility/execution of Accelerated Bridge Construction (ABC)
• Optimization of scope of work for highway project (Virginia)

Area of discussion: Pavement design of road in hilly terrain where road grade is > 4%
The aforementioned expressway has substantially been completed and considerable portion is
opened for traffic now. It is pertinent to mention that the whole pavement design is flexible/asphalt
irrespective of road grade which was required to have been compared with alternate design namely
rigid pavement (concrete pavement) since asphalt pavement is more vulnerable to pavement distress
like corrugation (or wash boarding)[*]
due to application of brakes by heavy vehicles while moving
downgrade. Both flexible and rigid pavements are hereby compared with respect to the following
priorities/criteria
Flexible/Asphalt pavement Rigid/Concrete pavement
Cost Asphalt pavement is less costly. Concrete pavement is more costly than
asphalt pavement( when design is rich)
Time Time taken by asphalt pavement is less. Since concrete pavement is constructed
in panels, therefore more time is taken.
Performance Performance of asphalt pavement in hilly
terrain (grade> 4%) is not good.
Concrete pavement has better
performance in hilly area (grade > 4%).
Maintenance Due to pavement distresses, maintenance
cost is more.
Due to better performance, there is least
maintenance & hence little or no cost.

Decision. If we look at the above comparison, both types of pavements have pros & cons with
respect to various criteria. However, the crucial factor is performance in high grade areas where road
grade > 4% since in case of poor performance the road failure will occur which involves traffic
management and associated maintenance cost. The rigid pavement leads in such a scenario. Hence
the best option is rigid pavement in hilly area where road grade is more than 4%.

Conclusion
Based on the aforementioned discussions, it is concluded that MCA is the present day need. It has
been widely recognized in developed countries as decision making tool among various alternatives.
However in third world countries there are certain challenges regarding adoptability of this
technique like lack of resources, expertise and after all to educate the people regarding its
significance. Hence to go with rest of the world it’s a system which must be encouraged/adopted.
