Multi-person Decision Model for Unfinished Construction Project
Full text linkThis paper discusses a proposed model of multi-person decision on prioritizing selection with regard to continuing or terminating unfinished construction projects. This involved multiple steps including determining criteria and sub criteria, selecting and weighting of alternatives, optimizing, and analyzing coalition formation and agreement option. Criteria and sub criteria that were obtained from perspectives of 120 project managers are the first basis to construct decision hierarchy. The model is implemented in one of the biggest private construction projects in Indonesia. The implementation was based on the Analytic Hierarchy Process for multi criteria decision involving coalition and agreement options in a multi-person decision. Goal Programming was used to optimize based on cost constrains. The results demonstrate a process of multiperson decision to select priorities of each alternative to each decision and concluded that some of the projects were continued, postponed or terminated. The new direction of research presented in this paper presents some interesting challenges to those involved in modeling computer-based multi-person decision support utilizing both Multi Agent System and Multi Criteria Decision Making
Development of a Negotiation Support Model for Value Management in Construction
Full text linkDecision making for value-based design in Value Management (VM) is very
complicated due to the involvement of many parties. In such situation where the
designer, project manager, facility manager and others are involved in choosing a
single alternative from a set of solutions, a negotiation support is required to evaluate
and rank the solution before engaging into negotiation. This research presents a
conceptual model of negotiation support for VM. It consists of developing the
appropriate research approach, methodology of negotiation and agent-based
negotiation in VM.
The research objectives are to find a theoretical basis and research approach for
negotiation support methodology on VM, to develop a decision model for technical
solution options in a satisfying function/cost preferences, to investigate negotiation
style and outcome and analyze the correlation between them for the basis of scenarios
on the agent system, to develop a model for agreement options and coalition
algorithms on value-based decision, to validate the coalition algorithms and introduce
an initial model of Negotiation Support for Value Management (NSVM). A
triangulation methodology has been used to fulfill the objectives. It combines
simultaneous triangulation by using case studies and survey methods and sequential
triangulation in which results of one method are essential in planning the next method
(theoretical mapping, survey research, focus group, case study and conceptual
modeling).
The methodology is based on a theoretical approach which consists of value-based
decision nature in construction VM, multicriteria group decision making, game
theory, negotiation theory, and agent-based development. This methodology
combines value analysis method using Function Analysis System Technique (FAST);
Life Cycle Cost analysis, group decision analysis method based on Analytical
Hierarchy Process (AHP), and Game theory-based agent system to develop a
negotiation support
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Quantitative method for optimizing decision in project selection
Full text linkThe Indonesian economic and monetary condition recently has made
changeover in many development policies including built environment. For example is the
policy on selecting the built environmental project to be developed in the context of
sustainable both environment and business. This research’s report presents an approach to
apply quantitative methods for optimizing decision in built environment project selection. The
approach based on decision hierarchy that was obtained from 32 respondents in a survey
study. It was completed with an implementation by a case study that is one of the biggest
private construction projects in Indonesia to evaluate the application of that method. Model
formulated and its implementation based on application of Analytic Hierarchy Process (AHP)
method for multi criteria decision and Goal Programming (GP) method for multi objective
decision and its optimization in a project selection. The result presents that complete design
and permission; available funds; construction cost and probability to capital return are the
most significant factors in decision. The implementation result demonstrates a process to
select priorities each project to each decision and the optimization concludes that public park
project, landfill sanitation project and supermarket project are selected and to be continued,
but swimming pool is delayed and hospital is terminated. Follow up research is particularly
required, primarily a study of decision support system and expert systems
SATISFICING OPTION FOR BENEFIT COST ANALYSIS IN A HOUSING INFRASTRUCTURE PROJECT SELECTION
Full text linkDecisions in large-scale housing project infrastructure planning are complex because they involve multiple parties such as planners, engineers, funders, and constructors. Many decisions during the development phase of the project such as routes and driveways and the location of construction materials. This paper presents a decision model that can be applied in the determination of alternative housing project development projects. The research used the process of satisficing option method where the benefits and cost for each alternative as a technical solution can be formulated on project evaluation. They are categorizing by the problem, comparing the benefits and costs, and representing the value of the project. Its scale is presented same. By creating Ps and Pr, the process can be done. Ps is a choice function that represents the project benefits and Pr is rejectability that represent project costs and normalize the problem. It makes the decision maker has a cost and benefit value to evaluate the proposed project. This method encourages future research for multi disciplines group decisions involving collaborative and negotiation processe
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
