A group decision must be made when a design process is conducted by more than one person. In this situation, negotiation plays an important role in many design decision. Value Management (VM) is one of design decision methodology in construction. By involving multi disciplines, collaboration and teamwork, negotiation becomes an important role on VM using a value-based group design decision. This paper provides an approach to develop a conceptual model of agreement options for group decision in building wall system selection using value criteria which are function and cost. The characteristic of value criteria has not been applied on previous researches. Existing models which are commonly accepted are optimization-based models, for example aggregation methods, but these are not able to solve the problem of value criteria on VM. Group decision needs to identify the goals that can be optimized and those that can be compromised in order to reach an agreement among decision makers. Agreement options are determined by identifying the potential decision makers followed by determining the optimal solution for each sub-group. Five stages are conducted to identify and determine agreement options as a conceptual model which are determining the weighting factor of criteria for each decision maker; grading alternative for each evaluation criteria; scoring every alternative for every decision maker; determining the optimal solution; and determining the fitness factor of an alternative solution The agreement option model is facilitated to better design decision. The model developed in this research can be used for any development research on group decision and negotiation in design process within the construction industry. Future research in the application of this methodology in many field of decision will build a wide range of knowledge to solve the theoretical and practical gap between automated design and automated negotiation.

A previous paper by the authors drew on existing research on e‐business and the smaller firm, developed a conceptual model and a set of research propositions. This paper analyses a series of qualitative, in‐depth interviews of owner/managers of smaller firms in central Scotland in order to test the research propositions. Results indicate that industry and sectoral factors play an important role in the level of e‐business development achieved. In many cases the customer determines the need for e‐business adoption, rather than any internally planned programme of adoption. Other important factors include the degree of entrepreneurial orientation of the key decision maker and the ability to exploit appropriate competencies. Recommendations for encouragement of e‐business development are made and suggestions for future research are included.

Selection of a most appropriate material is a very important task in design process of every product. There is a need for simple, systematic, and logical methods or mathematical tools to guide decision makers in considering a number of selection attributes and their interrelations and in making right decisions. This paper proposes a novel multiple attribute decision making (MADM) method for solving the material selection problem. The method considers the objective weights of importance of the attributes as well as the subjective preferences of the decision maker to decide the integrated weights of importance of the attributes. Furthermore, the method uses fuzzy logic to convert the qualitative attributes into the quantitative attributes. Two examples are presented to illustrate the potential of the proposed method.

Additive manufacturing facilitates the design of porous metal implants with detailed internal architecture. A rationally designed porous structure can provide to biocompatible titanium alloys biomimetic mechanical and biological properties for bone regeneration. However, increased porosity results in decreased material strength. The porosity and pore sizes that are ideal for porous implants are still controversial in the literature, complicating the justification of a design decision. Recently, metallic porous biomaterials have been proposed for load-bearing applications beyond surface coatings. This recent science lacks standards, but the Quality by Design (QbD) system can assist the design process in a systematic way. This study used the QbD system to explore the Quality Target Product Profile and Ideal Quality Attributes of additively manufactured titanium porous scaffolds for bone regeneration with a biomimetic approach. For this purpose, a total of 807 experimental results extracted from 50 different studies were benchmarked against proposed target values based on bone properties, governmental regulations, and scientific research relevant to bone implants. The scaffold properties such as unit cell geometry, pore size, porosity, compressive strength, and fatigue strength were studied. The results of this study may help future research to effectively direct the design process under the QbD system.

Introductory psychology students, 52 men and 52 women, made estimates of the consistency of a decision-maker in 24 hypothetical social influence situations. The decision-maker was either a group or an individual, and the petitioner who was attempting to influence a change in decisions was in either a weak or equal status relationship with the decision-maker. As hypothesized, subjects predicted that group decision-makers would be less likely to change than would individual decision-makers. Subjects also predicted greater consistency on the part of the decision-maker when the petitioner was weak than when he was equal in status with the decision-maker. There were interaction effects of sex of subject and sex of characters on stability predictions.

This paper introduces a concession equilibrium solution without weighted aggregation operators to multiattribute group decision-making problems (in short MGDMPs). It is of practical significance for all decision-makers to find an optimal solution to MGDMPs or to sort out all candidate solutions to MGDMPs. It is proved that under certain conditions the optimal concession equilibrium solution does exist, and on this important result the optimal concession equilibrium solution is obtained by solving a single objective optimization problem. Moreover, the optimal concession equilibrium solution is equivalent to the robust optimal solution with the group weight aggregation under the worst weight condition. Finally, it is proved that the concession equilibrium solution is equivalent to a complete order, i.e. all candidate alternatives can be sorted by concession equilibrium solution. By defining the triangular fuzzy numbers of target concession value, the optimal concession equilibrium solution or the order of the alternative solutions can be obtained in the range of objective concession ambiguity. Numerical experiment shows that the solution can balance the evaluations of multiattribute group decision makers. This paper provides a new approach to solving multiattribute group decision-making problems.

This paper introduces an approach for group decision-making problems (GDMP) without weighted aggregation operators. This approach is more suitable for scenarios with infinite number of individuals. A mathematical model approach is established based on the new concept of s⁎-optimal concession equilibrium solution without weighted aggregation operators for group decision-making problems. It is of practical significance for all decision-makers (experts) to find an optimal solution or to sort out all the candidate solutions. We prove that the s⁎-optimal concession equilibrium solution is equivalent to solving a single objective optimization problem, and, under certain conditions, the s⁎-optimal equilibrium solution always exists. Moreover, it is proven that the s⁎-optimal concession equilibrium solution is equivalent to the robust optimal solution of the group weight aggregation and the optimal solution under the worst weighted aggregation operators.

The research on comparative governance of non-profit organization (organisasi nir laba/ ONL) in case study on social welfare institution (lembaga kesejahteraan social/ LKS) of Mardi Wuto dan Hamba in Yogyakarta Indonesia aimed at finding out the difference of the governance model and practice of both LKS and the uniqueness of each LKS. LKS was one of non-profit organizations in Indonesia. The empirical data were obtained and the finding was described and interpreted based on qualitative case study. The interpretation was related to the normative expectation on the design and implementation of the management of both non profit organizations. The research finding of ONL Mardiwuto was that it had bureaucratic governance model indicated by the good interaction and relation of the stakeholders, as the value management stated on articles of association. Meanwhile, ONL Hamba had democratic governance model indicated by the very good interaction and relation of the stakeholders, beyond the value management stated on articles of association. The weakness of the research was that the sample was still limited. Then, for the future research, it was suggested that the sample would be more various, and the implication of the research was it could be a reflection material for the decision makers and the managers of ONL.

Decision Matrix

Multiple Criteria Decision Making methods, such as TOPSIS, have become very popular in recent years and are frequently applied to solve many real-life situations. However, the increasing complexity of the decision problems analysed makes it less feasible to consider all the relevant aspects of the problems by a single decision maker. As a result, many real-life problems are discussed by a group of decision makers. In such a group each decision maker can specialize in a different field and has his/her own unique characteristics, such as knowledge, skills, experience, personality, etc. This implies that each decision maker should have a different degree of influence on the final decision, i.e., the weights of decision makers should be different. The aim of this paper is to extend the fuzzy TOPSIS method to group decision making. The proposed approach uses TOPSIS twice. The first time it is used to determine the weights of decision makers which are then used to calculate the aggregated decision matrix for all the group decision matrices provided by the decision makers. Based on this aggregated matrix, the extended TOPSIS is used again, to rank the alternatives and to select the best one. A numerical example illustrates the proposed approach.

The environmental decision problems often are divisive, even in a technical realm, decision makers with strong personalities influence outcomes. The purpose of this study is to define and quantify the factors that affect the conservation objectives of a national natural park located in Colombia, South America adding the judgments of six decision makers with different knowledge (every decision maker is also a stakeholder representative). This paper uses a hybrid multiple criteria group decision-making model (MCDM), combining the social network analysis (SNA), analytic hierarchy process (AHP) and similarity measures to solve the consensus and anchoring problem among environmental decision makers. The SNA technique is used to build an influential network relation map among decision makers and to obtain their weights for applying a weighted AHP. Then, the final decision matrices for every decision maker are compared between them in order to identify the consensus level of the problem.

Interval Weight

<p>The individual and group decisions in this study are denoted as the normalized interval weights of alternatives as in Interval AHP. It assumes that a decision maker uses crisp values in the interval weights in giving comparisons. The interval weights reflect uncertainty in a decision maker’s mind. Then, the group interval weight is obtained as a conjunction approximation of the individual interval weights. For a consensus, the group interval weight is obtained so as to intersect with all the individual interval weights. In other words, the group interval weight has something in common with each individual interval weight. The group decision depends on how much the decision makers are satisfied or dissatisfied with it. The satisfaction of a decision maker is measured by the ranges of the group interval weights which s/he can support. Similarly, the decision maker’s dissatisfaction is defined by the ranges which are out of his/her decision. It is better to maximize the satisfaction and simultaneously to minimize the dissatisfaction. However, there is a trade-off between these two objectives. In the proposed model, the importance of the satisfaction or dissatisfaction is given. Then, the decision makers find not only the group decision but also their satisfaction and dissatisfaction with it. </p>
