Selection of the Best Proposal using FAHP: Case of Procurement of IT Master Plan’s Realization

IT master plan, which allows planning and managing the development of the computer systems, derives its importance in the central role of the computer systems in the functioning of organizations. This article focuses on the use of FAHP method for analysis and evaluation of tenders during the awarding of contracts of IT master plan’s realization. For those purposes, a painstaking work was realized for making an inventory of criteria and sub-criteria involved in the evaluation of tenders and for specifying the degrees of preference for each pair of criteria and sub-criteria. To find a provider for the IT master plan’s realization, organizations are increasingly using tendering as the mode of awarding contracts. This paper is an improvement of a previous published paper in which AHP method was used. The goals of this work are to make available to members of tenders committee a decision support tool for evaluating tenders of IT master plan’s realization and endow the organizations with effective IT master plans in order to increase their information systems’ performance

A holistic multi-methodology for sustainable renovation

A review of the barriers for building renovation has revealed a lack of methodologies, which can promote sustainability objectives and assist various stakeholders during the design stage of building renovation/retrofitting projects. The purpose of this paper is to develop a Holistic Multi-methodology for Sustainable Renovation, which aims to deal with complexity of renovation projects. It provides a framework through which to involve the different stakeholders in the design process to improve group learning and group decision-making, and hence make the building renovation design process more robust and efficient. Therefore, the paper discusses the essence of multifaceted barriers in building renovation regarding cultural changes and technological/physical changes. The outcome is a proposal for a multi-methodology framework, which is developed by introducing, evaluating and mixing methods from Soft Systems Methodologies (SSM) with Multiple Criteria Decision Making (MCDM). The potential of applying the proposed methodology in renovation projects is demonstrated through a case study

Bid-Centric Cloud Service Provisioning

Bid-centric service descriptions have the potential to offer a new cloud service provisioning model that promotes portability, diversity of choice and differentiation between providers. A bid matching model based on requirements and capabilities is presented that provides the basis for such an approach. In order to facilitate the bidding process, tenders should be specified as abstractly as possible so that the solution space is not needlessly restricted. To this end, we describe how partial TOSCA service descriptions allow for a range of diverse solutions to be proposed by multiple providers in response to tenders. Rather than adopting a lowest common denominator approach, true portability should allow for the relative strengths and differentiating features of cloud service providers to be applied to bids. With this in mind, we describe how TOSCA service descriptions could be augmented with additional information in order to facilitate heterogeneity in proposed solutions, such as the use of coprocessors and provider-specific services

Optimization of the supplier selection process in prefabrication using BIM

Prefabrication offers substantial benefits including reduction in construction waste, material waste, energy use, labor demands, and delivery time, and an improvement in project constructability and cost certainty. As the material cost accounts for nearly 70% of the total cost of the prefabrication project, to select a suitable material supplier plays an important role in such a project. The purpose of this study is to present a method for supporting supplier selection of a prefabrication project. The proposed method consists of three parts. First, a list of assessment criteria was established to evaluate the suitability of supplier alternatives. Second, Building Information Modelling (BIM) was adopted to provide sufficient information about the project requirements and suppliers’ profiles, which facilitates the storage and sharing of information. Finally, the Analytic Hierarchy Process (AHP) was used to rank the importance of the assessment criteria and obtain the score of supplier alternatives. The suppliers were ranked based on the total scores. To illustrate how to use the proposed method, it was applied to a real prefabrication project. The proposed method facilitates the supplier selection process by providing sufficient information in an effective way and by improving the understanding of the project requirements

Multi-Criteria Analysis in Compound Decision Processes. The AHP and the Architectural Competition for the Chamber of Deputies in Rome (Italy)

In 1967, a national architectural competition was released for a preliminary project proposal, aimed at the realization of the new building for the Chamber of Deputies in Rome. The outcomes of that competition were unusual: eighteen projects were declared joint winners, and no winner was consequently selected. With reference to that event, this research aims to examine the usefulness of the evaluation tools that are currently employed and the positive effects that one of these techniques would have had, as support for the identification of the “winner” project, are highlighted. Therefore, an hypothetical examination/adjustment of the decision process of that competition through the Analytic Hierarchy Process (AHP) is developed, analyzing the outputs obtained by the implementations of this technique on the final decision. In addition to confirming the usefulness of the evaluation tools for compound and conflicting decision processes, the results of this experiment led to a further understanding of the socio-cultural dynamics related to the original outcomes of the competition analyzed.

Tender Evaluation for the Telecommunication Industry using the Analytic Network Process

In the past few decades, tender evaluation has consistently dominated most of organizations\u27 top strategic priorities. Additionally, the field of tender evaluation has generated a vast amount of research efforts, wherein most of these efforts center on methods enabling consideration of all affecting criteria together to make an appropriate decision. Despite the great deal of advances in the methods of tender evaluation based on technical view, there still lacks comprehensive and organizational-driven decision making tools to support organizations during the crucial task of choosing a suitable tender that best meets their business and technical needs.;Tender evaluation has a strategic role in the success of large enterprises in the telecommunication market. It is a complex, multi-person, multi-criteria process. The criteria used to evaluate a tender contain quantitative which are easy to measure and qualitative attributes which most available methods fail to deal with them. In this study, a model is developed using Analytic Network Process (ANP) in a Benefit, Opportunity, Cost, and Risk (BOCR).;The essence of this approach is decomposition of a complex problem into a hierarchy with objective at the top of the hierarchy, criteria and sub-criteria at levels and sub-levels of the hierarchy, respectively, and decision alternatives at the bottom of the hierarchy. Factors at given hierarchy level are compared in pairs to assess their relative preference with respect to each of the factors at the next upper level. These can support complex problems that would be otherwise difficult to handle. This method is capable of handling discrete criteria of both quantitative and qualitative in nature and provides complete ordering of the alternatives.;The primary feature of this methodology is its ability to simultaneously consider all types of criteria for tender evaluation in telecommunication companies. The criteria defined for the model using Delphi method from experts in the field and are general to all telecommunication tenders. The developed model is used in an empirical study on an ongoing tender in a mobile telecom service provider company to analyze the tenderers\u27 data and evaluate and rank them. The result of this model is compared to the company\u27s evaluation result which is obtained from traditional Texas Instruments Matrix method. The proposed model shows the ranking of the tenderers in different BOCR merits separately as local priorities to help the evaluators make a more efficient decision. A sensitivity analysis on the empirical study was conducted to show how the rankings of the tenderers are changing by changing the weights of the BOCR merits.;The research work presented here may be used by telecommunication professionals and managers to aid in making appropriate decisions on tender evaluation process and determinate strategies for reducing the risk of this process

A New Approach to Supplier Selection Problem: An Introduction of AHP-SCOR Integrated Model

Nowadays manufacturing industry is growing rapidly and large numbers of added value in business activities has been exercised. Supplier selection problem has improved in many areas by evaluation of supplier to increase supply chain performance. Supplier selection is one of the most important aspects in manufacturing industry. This paper suggest a combination techniques of Analytical Hierarchy Process (AHP) together with Supply Chain Operation Reference (SCOR) model to develop new decision support system (DSS) to the industry. There are four stages in supplier selection process which employed the norm stages of supplier selection process: data gathering, AHP calculation, SCOR evaluation, and implementation of decision making. Data analyzed was aligned with evaluation of data to synthesize of priorities and consistencies measurement. Organization’s decision maker would gain benefits and acquire competitive advantage providing DSS practitioners to achieve a success of the holistic approach in future decision support system.

Multi-criteria Contractor Selection Framework for Indian Construction Projects

In this paper contractor selection practice in India has been analyzed in detail to find out the gaps in the prevailing system & also compared with the selection systems outside India. This study aims to develop a multi-criteria contractor selection framework that can incorporate multiple evaluation criteria along with the relative weightage. In this study, it has been identified that in India, as per the guidelines the contractor selection in the case of most popular Design Bid Build (DBB) projects is done based on Least Cost Selection (LCS) only. In LCS, the final selection is based on cost or bid price only. In some cases, Quality & Cost Based Selection (QCBS) is applied for contractor selection. However, QCBS is mainly used for consultant selection or selection of service providers. On the other hand, in many other counties, there are systems that follow multiple criteria for contractor selection to ensure the overall performance of the contractor. Hence, in India, there is a need for a structured, multi-criteria contractor selection system. The system should cater to the objective of contractor selection in the case of DBB projects & also should be responsive to the present need for selection based on multiple criteria
