“…Distance matrix calculations enable the computation of distances between nodes that represent destinations and origins, while allocation-location functions ascertain site locations, at the same time assigning demand to sites. These GIS capabilities for the analysis of spatial networks facilitate their use as decision support systems for vehicle routing [18]. The focus of this paper is finding near optimal solutions for the TSP-TW problem.…”

“…This work is inspired by our previous effort to treat the general garbage collection scenario by modeling it as the Travelling Salesman Problem [19]. As no polynomial time algorithm is expected for finding solutions to any form of the TSP, Keenan et al [18] contend that one of the most popular approaches is the heuristics approaches. There are variations among heuristics in terms of performance, implementation difficulty and computation time.…”

“…Using this benchmark as an input to our quantum inspired implementation, we have found out a feasible solution for our benchmark. The order of the nodes after the execution is the following: [0, 6,2,11,19,3,4,8,5,14,15,10,9,7,20,13,18,16,0,12,17,1], and the resulting cost of the produced solution is 319.0. The above results are quite promising and encourage us to apply our research on alternative optimization models to other real world problems as well.…”

GVNS, which stands for General Variable Neighborhood Search, is an established and commonly used metaheuristic for the expeditious solution of optimization problems that belong to the NP-hard class. This paper introduces an expansion of the standard GVNS that borrows principles from quantum computing during the shaking stage. The Traveling Salesman Problem with Time Windows (TSP-TW) is a characteristic NP-hard variation in the standard Traveling Salesman Problem. One can utilize TSP-TW as the basis of Global Positioning System (GPS) modeling and routing. The focus of this work is the study of the possible advantages that the proposed unconventional GVNS may offer to the case of garbage collector trucks GPS. We provide an in-depth presentation of our method accompanied with comprehensive experimental results. The experimental information gathered on a multitude of TSP-TW cases, which are contained in a series of tables, enable us to deduce that the novel GVNS approached introduced here can serve as an effective solution for this sort of geographical problems.

“…These analyses have been improving the evaluation and decision-making models for more environmentally-friendly products and processes. Applications of DDS in environmental management can be observed in applications that are related to urban development [29,31], occupational health and safety [32], construction waste management [33,34], and Geographic Information System (GIS) [35]. According to Kazak and Hoof [29], The DDS tools development should consider 3 keys aspects: (a) the ability to quantify features to reduce subjectivity and increase reliability; (b) the size of the potential results, according to the intended objective, ranging from the comparison within a finite set of choices to the use of open list to test solutions through an interactive process; and (c) the degree of uncertainty, considering the changes between the initial conditions and the implementation process.…”

The traditional decision-making process in construction is still driven by factors such as cost and time, not adequately addressing indicators to control their environmental impacts. So, how to improve environmental communication to incorporate sustainable building practices. The incorporation of environmental indicators may enlarge the scope of construction management tools. In the case of cost databases, widely used in the construction sector, this action can contribute to the communication and dissemination of environmental practices. This paper mapped 24 indicators from construction cost databases to assess their ability to communicate and disseminate environmental information. The research comprised: (a) a review of the use of cost bases in the environmental study, (b) identification of the most cited bases in 27 Brazilian civil engineering courses, and (c) analysis of the selected databases through of the assessment matrix, it crosses cost data versus environmental information. CYPE, TCPO, and ORSE presented performance medium, and higher results than SINAPI, BDCCM, and BCCA. The tools presented low control over environmental information, such as water and energy consumption, machine circulation and pollution generation. However, it has been observed that when adding environmental indicators, these tools can contribute significantly to disseminate good practices in its wide user base.

“…The literature review on PSS utilization in the strategic planning process within local communities indicates two main groups of practical barriers. The first one is the lack of usability in terms of user-friendliness, PSS accessibility, ease, and use efficiency in both individual and group processes [69][70][71][72][73][74][75], and the second one is the issue of usefulness in terms of validity, and credibility for planning in a specific context [76][77][78][79][80][81][82]. The complexity of PSS usability and usefulness identified within the planning agencies rise when explored from a higher organizational level, such as a local governance perspective [83][84][85][86][87][88][89].…”

An Integral Approach to the Modeling of Information Support for Local Sustainable Development—Experiences of a Serbian Enabling Leadership Experiment

et al. 2019

Collaborative strategic decision making has to be widely informed, communicated and knowledge-based in order to innovate transformations toward local and global sustainability. It is unimaginable that this process could be effective without computer-aided information support, but the research indicates the utilization constraints within human capacities to recognize their usability and usefulness. These constraints seem to be even more challenging within the intensively transitional social contexts, such as Serbia. We argue that understanding the relationships between sustainability, governance, and planning in a specific social context has profound importance to gain usefulness of information support and to ensure its increasing utilization. Identifying the practical path of information support modeling requires an operational framework that encompasses innovative and socially valid initiatives. Therefore, an integral theory framework was chosen to comprehend all social influences on the information support of successful utilization. This article presents the integral framework of the information support’s conceptual setting, which was used to build up community-based collaborative action research (CBCAR) as a transformative social learning process that enables information support utilization, and it was tested in six municipalities of Serbia. The implementation of pilot territorial information support (TIS) initiatives resulted in continuous and proactive local community efforts in information support development and usage.
