Goal: This paper aims to facilitate production-planning strategies for demand responsiveness. Our paper implements graph-rewriting systems towards supporting operative decision making in production environments. Design/Methodology/Approach: We design a decision support approach which is able to recognize and resolve conflicts amongst workstations in a hybrid production system. During the proposed stages of the presented approach, we rewrite the hybrid system by means of graph representation procedure, identify conflicts among the workstations by means of the developed graph coloring algorithm, and evaluate performance of the reorganized system by defining key performance indicators for the presented system. Results: We prove that the graphs’ chromatic numbers in such systems are less than or equal to entire number of dummy nodes applied to the system by means of our proposed algorithm. Furthermore, the presented structure improves the performance of the system by analyzing production bottlenecks. Limitations of the investigations: we only considered the Key Performance Indicators according to products, workstations, and customers. However, the problem can be more generalized by adding some more elements. Practical Implications: Our methodology enables managers to assess the performance of the reorganized system after applying the heuristic algorithm, by means of representing a performance evaluation procedure. Originality/ Value: We focus on presenting a novel structure to help companies using hybrid make-to-stock (MTS)/make-to-order (MTO) production strategies to (1) identify conflicting workstations and the relations among them, (2) propose dialectical prioritization rules and techniques by means of graph-coloring concepts for resolving the conflicts, (3) reorganize the system, and evaluate performance.

Goal: Propose hybrid heuristics combining VNS and Tabu Search (TS) for adding adaptability to University Course Timetabling Problem (UCTTP) resolution. Design / Methodology / Approach: VNS and TS metaheuristics were used isolated and in combination in order to verify which shape acquired the best solutions. Those heuristics were verified using constraints found at two undergraduate courses of Federal Fluminense University. Effectiveness is verified by comparing them with solutions manually elaborated by undergraduate course coordinators. Results: The computational results showed the efficiency of the hybrid VNS-TS heuristics, with emphasis on the heuristic VNS-TS1, which uses tabu search as local search method. Limitations of the investigation: This research was applied using data from two undergraduate courses of Federal Fluminense University. New experiments on data from other universities will soon be carried out. Practical implications: The hybrid heuristic VNS-TS1 has been in use since the first half of 2019 by some of UFF undergraduate courses coordinations. Even though each university has specific constraints on its timetable, the use of the proposed heuristics is possible because it has been developed using the framework FINESS that allows for the easy insertion and removal of constraints. Originality / Value: We have the following innovative contributions: Development of heuristics with a high degree of adaptation to the needs of educational institutions; Two proposed VNS-TS heuristics; Proposed VND-TS improvement method.

Marcele Elisa Fontana marcelelisa@gmail.com Federal University of Pernambuco, Caruaru, PE, Brazil ABSTRACT Goal: This study aimed to propose a procedure to survey of the Critical success Factors (CSF) in the reverse flow inventory management. Design / Methodology / Approach: A problem structuring method (PSM) combined with an approach for analysis of strategic map were used to facilitate and share information in a participatory process, considering all the stakeholder’s perspectives in order to identify and analyse the CSF. A case study of returnable packaging in the metallurgy and steel industry was conducted to validate the proposal. Results: The proposal was able to minimize conflicts and it facilitated the discussions on the CFSs surveyed. In addition, the decision makers have confirmed that their viewpoints were well represented in the strategic map, and they will use the CFS to evaluate the operations performance. Limitations of the investigation: Although the surveyed CSFs are specific to the presented case study, the procedure may be replicated in other organizations to identify their own CSF. Practical implications: The adequate survey of CSFs is fundamental because they have potential to explain the success or failure of a company, since CSFs impact directly on profits, processes performance and competitive environment. Originality / Value: The main contribution was to propose a methodology to survey critical success factors in the reverse flow environment adequate to messy, complex and unstructured situations, as well as this methodology was able to make a cyclic analysis and comprehension of the multiple perspectives, important in group decision maker environments.

Kenan Karagul kkaragul@pau.edu.tr Pamukkale University, Dept. of Logistics, Honaz, Denizli, Turkey. ABSTRACT Goal: This paper aims to implement a periodic capacitated vehicle routing problem with simulated annealing algorithm using a real-life industrial distribution problem and to recommend it to industry practitioners. The authors aimed to achieve high-performance solutions by coding a manually solved industrial problem and thus solving a real-life vehicle routing problem using Julia language and simulated annealing algorithm. Design / Methodology / Approach: The vehicle routing problem (VRP) that is a widely studied combinatorial optimization and integer programming problem, aims to design optimal tours for a fleet of vehicles serving a given set of customers at different locations. The simulated annealing algorithm is used for periodic capacitated vehicle routing problem. Julia is a state-of-art scientific computation language. Therefore, a Julia programming language toolbox developed for logistic optimization is used. Results: The results are compared to savings algorithms from Matlab in terms of solution quality and time. It is seen that the simulated annealing algorithm with Julia gives better solution quality in reasonable simulation time compared to the constructive savings algorithm. Limitations of the investigation: The data of the company is obtained from 12 periods with a history of four years. About the capacitated vehicle routing problem, the homogenous fleet with 3000 meters/vehicle is used. Then, the simulated annealing design parameters are chosen rule-of-thumb. Therefore, better performance can be obtained by optimizing the simulated annealing parameters. Practical implications: In this study, a furniture roving parts manufacturing company that have 30 customers in Denizli, an industrial city in the west part of Turkey, is investigated. Before the scheduling implementation with Julia, the company has no effective and efficient planning as they have been using spreadsheet programs for vehicle scheduling solutions. In this study, the solutions with Julia are used in practice for the distribution with higher utilization rate and minimum number of vehicles. The simulated annealing and savings algorithms are compared in terms of solution time and performance. The savings algorithm has produced better solution time, the simulated annealing approach has minimum total distance objective value, minimum number of required vehicles, and maximum vehicle utilization rate for the whole model. Thus, this paper can contribute to small scale business management in the sense of presenting a digitalization solution for the vehicle scheduling solution. Also, Julia application of simulated annealing for vehicle scheduling is demonstrated that can help both academicians and practitioners in organizations, mainly in logistics and distribution problems. Originality / Value: The main contribution of this study is a new solution method to capacitated ve

Goal: This article aims to present a mathematical modelling study to quantify greenhouse gas emissions in the scope of urban mobility and propose actions for more sustainable cities. Methodology: This presents an application focused on trips made by cars and motorcycles in some neighborhoods of the City of Rio de Janeiro during 2016 in order to quantify from mathematical equations the greenhouse gas emissions and their proportion to the total greenhouse gases emission of transport in the city, while presenting the capacity of the current bicycle infrastructure to absorb the same displacements with zero carbon trips. Results: The study reached the result of 127 thousand tons of greenhouse gases emitted by cars and motorcycles, representing 1,64% of the total transport emissions and 2,73% of road transport in this city in 2016. Limitations of the investigation: The research is limited to the neighborhoods under analysis and the daily travel rate per inhabitant by type of transport. Practical implications: The study provides environmental impact assessment material able to support proposals for practical applications aimed at mitigating greenhouse gas emissions. Originality / Value: Measurement of environmental impacts and applications in the transport of the city of Rio de Janeiro, which can be used for comparisons with other neighborhoods in the city and/or other cities.

Goal: The purpose of this research was to determine the most frequently used performance measures for the evaluation of reverse logistics in Brazilian companies. Furthermore, we sought to verify whether a correlation exists between certain performance measure dimensions (cost, asset management, customer service, and productivity), company size (micro, small, medium, and large), and their sectors of the economy. Design / Methodology / Approach: A survey of 125 Brazilian companies from different industrial sectors was conducted. Hypothesis testing allows carrying out inferences about population parameters, and the results indicate the acceptance or rejection of the hypothesis formulated. Results: This study presents a list of measures for the assessment of reverse logistics in different industrial segments, evidencing the major performance measures used. According to statistical analysis, large-sized companies are those that most frequently adopt performance measures to assess reverse logistics in Brazil. However, no correlation was verified between the performance measure dimensions evaluated and the sectors of the economy. Limitations of the investigation: This study could not conclude about the maturity level of performance measurement in the investigated companies. The results presented are the first step towards reverse logistics performance measurement and more complementary studies are necessary. Practical implications: This paper presents a list of performance measures for reverse logistics assessment. This information could support decision making as it provides a possibility of analyzing the choice of the best measures. Originality / Value: The main contribution of this paper is related to the scarcity of reverse logistics metrics in the literature. As an exploratory study, it could be used to improve the reverse logistics performance measurement studies and practice.

Goal: This paper analyses how European countries of Global Innovation Indicators (GII) present in the ranking by multicriteria support aid analysis. Design / Methodology / Approach: The methodology uses Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) for ranking countries and PROMETHÉE (Preference Ranking Organisation Method for Enrichment Evaluations) for outranking them. Results: There was change in 30 ordered positions from 39 countries observed. At noncompensatory method the overrating become “easier” than the compensatory method, especially when there are many alternatives and criteria for computing with small difference among values. Limitations of the investigation: It is only used the GII 2015 Europe for continuing investigations about MCDA realized for Latin America (2017) and Asia and Africa (2019). Practical implications: The applications result in a different understanding about TOPSIS ranking application, from original score list at GII; and also the perception of organized groups at outranking application. Originality / Value: Observing GII via MCDA is possible to see changing’s in the ranking according to countries profiles different from GII raking. Although European profiles seem to be similar, it is important to observe other perspective of grouping by them; suggesting quantitative studies inclusion and innovative trends.

Goal: This paper aims to analyze the economic feasibility of the inclusion of solar energy boiler in the production process in a chemical industry. Design/Methodology/ Approach: The research method used was documentary analysis in organizational reports, interviews with suppliers and observation. For the feasibility analysis of the solar energy inclusion project, Payback, Internal Rate of Return (IRR) and Net Present Value (NPV) calculations were performed. Results: Results show that the adequacy of the production system from the use of solar energy contributes to the three areas of the Triple Bottom Line (TBL), that is, economical because its contributions to the organization's long-term cost reduction, social by ensuring greater safety to workers around the boiler and environmental by reducing the rate of greenhouse gases emissions from burning fossil fuels. Limitations of the investigation: The paper limitations are related to the fact that the study was made from data collected in a single organization from chemical industry sector to trace the feasibility of the project, this fact does not allow us to assume generalizations to other companies in the sector. Practical implications: The study shows the importance of adopting new production systems based on cleaner energies and what contributions can be achieved on sustainability by organizations, society and the environment. Originality/Value: By analyzing the feasibility of adapting a production system to a chemical industry, the study contributes to the field of research on environmental management and sustainability.

Goal: Analyzing critical success factors (CSFs) for integrating sustainability and quality in a food and beverage company in Rio de Janeiro, Brazil. Design / Methodology / Approach: This research relies on an exploratory method, applied on qualitative data collection based on a case study. The instrument for data collection is an interview with professionals who work in the areas of quality and sustainability in the company studied. Results: Out of the seven critical success factors identified in an organization, six of them (leadership and commitment to strategy, management and monitoring of processes, training and communication, commitment to the three pillars of sustainability, product/service development and continuous improvement) are a result of the company’s strategic circumstances, achieved by continuously improving products and processes. On the other hand, there is a critical focus factor for stakeholder relations, since it is currently very concentrated on the interests of final consumers to the detriment of other stakeholders. Limitations of the investigation: Results reflect the Brazilian headquarters of a multinational company of the food and beverage sector and, therefore, cannot necessarily be applied to other companies of the same sector. Practical implications: Diagnosing seven critical success factors of the studied food and beverage company raises the opportunity to seek mechanisms to strengthen the focus on stakeholders, a critical factor identified as incipient in the research. Originality / Value: Findings confirm the relevance of looking into the critical success factors identified by the literature about integrating sustainability and quality in the practice of industries.
