“…The literature review approach stands on the grounds of previous research, and might reproduce similar models for different cases. The Delphi (Adler & Ziglio, 1996) or fuzzy Delphi methods (Chang, Tsujimura, Gen, & Tozawa, 1995) rely on seasoned experts' opinions. Nevertheless, when regarding a particular problem, even qualified experts might have diverse opinions; once the involved dimensionalities are large, the consistency of their judgments may be a concern.…”

A recent review discussed a variety of hybrid multiple criteria decision-making (HMCDM) methods on the subject of sustainability issues. Some soft computing techniques, such as the fuzzy set, have contributed significantly to HMCDM studies, emulating the imprecise or uncertain judgments of experts/decision makers in a complex environment. Nevertheless, a new rising trend in HMCDM, known as multiple rule-based decision-making (MRDM), which has the advantage of revealing understandable knowledge for supporting systematic improvements based on influential network relation maps (INRM), was not discussed in the review. This study therefore attempts to extend the review by introducing recent developments and the associated work on MRDM for solving practical problems, updating the discussion.

“…A Delphi approach, put forward by Dalky and Helmer, was employed to get the most dependable common view among several experts and was diffusely applied to make a strategic decision as well as forecasting [38]. The traditional Delphi method provides a chance for experts to obtain replies and revise their views using four rounds of consultations [39], which is time-consuming and hard to obtain consensus via redundant surveys. Then, a fuzzy-Delphi approach was put forward to alleviate these disadvantages, which integrated the traditional Delphi method with fuzzy theory.…”

With the increasing development of renewable resources-based electricity generation and the construction of wind-photovoltaic-energy storage combination exemplary projects, the intermittent and fluctuating nature of renewable resources exert great challenges for the power grid to supply electricity reliably and stably. An energy storage system (ESS) is deemed to be the most valid solution to deal with these challenges. Considering the various types of ESSs, it is necessary to develop a comprehensive assessment framework for selecting appropriate energy storage techniques in establishing exemplary projects combining renewable resources-based electricity generation and an ESS. This paper proposes a multi-criteria decision making (MCDM) model combining a fuzzy-Delphi approach to establish the comprehensive assessment indicator system, the entropy weight determination method, and the best-worst method (BWM) to calculate weights of all sub-criteria, and a Vlsekriterijumska Optimizacija I Kompromisno Resenje (VIKOR) comprehensive evaluation model to choose the optimal battery ESS. In accordance with the comprehensive evaluation results, the Li-ion battery is the optimal battery ESS to apply to wind-photovoltaic-energy storage combination exemplary projects. Based on the discussion on the comprehensive evaluation results, policy implications are suggested to improve the applicability of battery ESSs and provide some references for decision makers in related fields.

“…The first works applying fuzzy logic to project scheduling problem was by Prade (1979) and Chanas and Kamburowski (1981) applying fuzzy numbers with triangular membership functions based on optimistic, the most likely, and the pessimistic estimates of the respective activity durations. Chang et al (1995) proposed a project planning based on fuzzy Delphi method, and Chen and Chang (2001) dealt with the problem of finding Multiple Possible Critical Paths using Fuzzy PERT.…”

Abstract:In scheduling, estimations are affected by the imprecision of limited information on future events, and the reduction in the number and level of detail of activities. Overlapping of processes and activities requires the study of their continuity, along with analysis of the risks associated with imprecision. In this line, this paper proposes a fuzzy heuristic model for the Project Scheduling Problem with flows and minimal feeding, time and work Generalized Precedence Relations with a realistic approach to overlapping, in which the continuity of processes and activities is allowed in a discretionary way. This fuzzy algorithm handles the balance of process flows, and computes the optimal fragmentation of tasks, avoiding the interruption of the critical path and reverse criticality. The goodness of this approach is tested on several problems found in the literature; furthermore, an example of a 15-story building was used to compare the better performance of the algorithm implemented in Visual Basic for Applications (Excel) over that same example input in Primavera© P6 Professional V8.2.0, using five different scenarios.
