Goal: This research aims to investigate how to maximize the throughput and reduce the waiting time for oncological patients of a radiotherapy process. Design / Methodology / Approach: A case study was conducted to develop a simulation model integrated with optimization techniques, including an expert system to support everyday decision making in the operation. Results: The experiments demonstrated that the approach was able to identify better configurations of the process, improving productivity without deteriorating quality. Results also considered the future acquisition of a new linear accelerator allowing the operation to plan its ramp up accordingly. Another result is the devised tool to allow the operation to run its own simulation studies. Limitations of the investigation: The results are valid for processes with similar characteristics of the one studied in the present paper, closing the scope at the treatment stage. Practical implications: This work demonstrates the possibility of applying modern simulation techniques in radiotherapy, not only enabling improvements for the present situation but also integrating the model to the operation to support everyday decision making. Originality / Value: The number of details captured by the model is significantly higher than others studies. The integration of the methodology to the treatment process makes possible for the operation to continue benefiting from the model in a long term.

Goal: This article aims to present a systematic approach to improve the resource allocation and human queues prioritization patterns. Design / Methodology / Approach: To achieve such a purpose, effective criteria using a fuzzy-Delphi method, and subject-related researchers’ views were obtained. Utilizing the Analytic Network Process method, the weights of each criterion was measured. Then, considering the established weights and using a fuzzy-TOPSIS method, a prioritization system via Discrete Event Simulation was developed. Results: Results indicate that the established approach properly improved the performance of the prioritization system in terms of resources and facilities allocation in neurology’s ICUs. Limitations of the investigation: A drawback of this research can be in states of emergency which limits the options at hand and the criteria proposed may set a drawback on the aim of the study. Practical implications: The results show that the proposed model can modify patient entry based on multiple criteria in terms of productivity and social justice in the patient queuing strategy. Originality / Value: The contribution of this research is threefold: the literature has been reviewed to conclude the criteria concerning decisions around ICUs, the concluded criteria filtered through an expert panel which can be relied based on the method, a real application of the steps proposed is presented which allows comparing the accuracy and efficiency of the decisions made in the hospitals.

Goal: This paper aims to analyze to which extend the usage of information technology (IT) and business analytics (BA) have been explored in the context of sales and operations planning (S&OP). Design / Methodology / Approach: This study conducts a systematic literature review to synthesize the state of the art of IT and BA in S&OP. The review follows the rigorous approach by Thomé et al. (2016). Through the literature search, 442 results were retrieved, of which 57 were selected for the analysis. The results containing analytics techniques are classified by the planning tasks of S&OP that they address. Results: The analysis provides an overview of the dominant themes in the field of IT, BA and S&OP and leads to a classification of the existing research in the field of BA for S&OP. This study finds that IT can be an enabler of S&OP and that most analytics techniques address S&OP through fully-integrated optimization approaches. Yet, the impact on the S&OP process has not been explored. This study thus identifies gaps for future research and proposes a research agenda on BA on S&OP. Limitations of the investigation: The systematic literature review is restricted to the Elvesier SCOPUS database. SCOPUS has excellent coverage regarding relevant journals for this study. Despite SCOPUS being a prominent scientific database, other databases might reveal additional studies and further insights. Practical implications: The findings of this study provide insights on how IT and BA can support and influence the S&OP process. Originality / Value: In recent years, S&OP, IT and BA have seen a growing interest by scholars. To the best of the authors' knowledge, the number of published literature reviews on S&OP and BA is scarce. This study provides an overview of how IT and BA are used within S&OP.

Goal: identify the key competencies, in the perception of the senior officers and the warrant officers of the Air Force, necessary for the enlisted men to perform their functions and subject to consideration for updating the existing performance evaluation instrument. Methodology: preliminarily, a documentary and bibliographic research was carried out, capable of supporting the construction of a questionnaire, which was answered by 674 senior officers and 727 warrant officers belonging to the research target audience. Data were analyzed using centrality and dispersion parameters, also considering Pearson's coefficient of variation. Results: 29 competencies could be identified as being the main key competencies, highlighting those related to the alignment with military precepts. Limitations: it is possible to obtain a large amount of data using questionnaire, but the method does not allow to deepen the structure and processes that involve the questions asked. Also, distortions can occur caused by the subjectivity present in the respondents' perception. Practical implications: the results proved to be a proposal to updating the current performance evaluation system for enlisted men. Value: the value of this research is its contribution to a better performance evaluation system for the Brazilian Air Force enlisted men. Key Words: Competencies survey; Performance evaluation; Military promotion; Professional development.

Goal: Knowledge Management (KM) has been increasingly used by organizations to help innovation and gain competitive advantage; however, the implementation of KM may turn in bad results, because of functional isolation. In contrast, Business Process Management (BPM) is an approach that removes functional isolation, establishing end-to-end processes perspective through cycle promotion and usage of management techniques. Therefore, the aim is to understand how the techniques used to promote BPM contribute to KM. Design/ Methodology/ Approach: In step 1, a systematic review of the literature was carried out on the scientific bases, trying to understand how the literature dealt with the relationship between BPM and KM techniques in the last 10 years. In step 2, there was a project to promote BPM in a public hospital. Stage 3 sought to understand the leaders' perceptions about the possible contributions of BPM techniques to KM. Results: BPM acts promoting participation and sharing (social aspects); collecting information about the organization and identifies problems (cognitive aspects); allowing decision making to solve problems (strategic aspects); explaining tacit information, organizing and compiling explicit information (technological aspects) in order to enable changes in systems. Limitations of the investigation: single case study. Practical implications: BPM project collaborates to expand the diversity of information sources, opens the organization to external knowledge, with external consultant’s participation, also it provides communication expanding between areas, thus, improving customer service. Originality/ Value: this work contributes to show a valuable combination of techniques and how each one contributes to an essential resource as knowledge.

Goal: this study aimed to use the experimental simulation method to obtain the optimum results by using the simulation technique of the models, which are modeled mathematically but not solved. Design/Methodology/Approach: a case study was conducted to apply the discrete-event simulation (DES) approach based on the design of experiment (DOE) technique to derive strategies and analyze situations in an emergency department (ED). Results: by integrating the DOE approach with the DES technique for the ED, the average waiting time for a patient in a small ED was reduced from 40.09 minutes to 9.83 minutes (75.48%), which is a significant result. Increasing the capacity of the resources without increasing the number of daily resources for the ED resulted in an increase from 133 to 147 (10.53%) in the number of patients treated. Additionally, the optimum number of healthcare resources to employ in EDs was calculated. Limitations: there is no shift system for healthcare resources in the DES model. Since the ED was considered in this study, the same number of resources was run during the working hours of the DES model. Practical implications: for researchers and healthcare professionals, the developed method is used to obtain results that cannot be obtained through the mathematical modeling of healthcare problems. The results of the changes in health resources on the outputs are obtained by this method as the shortest time frame and lowest cost. Originality/Value: there is almost no detailed study of DES with the DOE technique. Providing high reliability has resulted in obtaining optimum values through the integration of the DOE approach with the DES technique in the healthcare area. It is very difficult to get accurate results anywhere where the human factor is present.

Goal: The purpose of this study was to investigate the factors affecting the purchasing decisions of consumers of green products. Design / Methodology / Approach: The sample of this study was composed of consumers of disposable products in Isfahan. In this study, Descriptive statistics is used for data analysis and Structural Equation Modeling is used test the research hypotheses and determine the effect of independent variables on the dependent variable. Results: Considering the critical values obtained from the research hypothesis test, it can be concluded that environmental protection, environmental responsibility, green product experience, environmentally friendly brands and social acceptance have a positive and significant effect on green product purchase decisions. Limitations of the investigation: Since the present study is an exploratory study, the findings of the study are limited to the sample and results may be changed if the sample is changed. Also, the sample of green product buyers' decisions was obtained from only one province, so the results may not be generalizable to all provinces of Iran. Practical implications: According to the results, it is recommended that environment-friendly companies differentiate their products from other products and price them appropriately. This should have an impact on consumers and encourage them to buy and use green products. Originality / Value: The design of the products in a recyclable form and making their components and materials reusable will in future cause their raw materials are recycled and reused; thus, buyers are more eager to buy green products with regard to environmental protection.

Goal: In this work, the application of FMEA (failure mode and effects analysis) in the execution of maintenance of water network in a medium size city in the state of Maranhao was approached. FMEA (failure mode and effects analysis) with occupational safety approach is applied in the execution of water supply network maintenance in a medium size city in the state of Maranhao. This work shows that FMEA is an effective tool for risk prioritization in work process. The FMEA application with use of index reference table can become faster than application without reference table - and thus spread the tool for risk analysis. Design / Methodology / Approach: A photographic records was carried out in loco and the main risks to the workers were enumerated and based on the obtained data, a risk analysis was elaborated with the application of FMEA (Failure modes and effects analysis). Results: The maintenance services teams of the supply system are subject to a high risk of accidents caused mainly by the working conditions precariousness. It was observed that the services of manual excavations and the lack of use of PPE (helmet, gloves, pants suitable for flooded environments and etc.) have high risk index (RPN) and that the mismanagement added to the unsafe behavior were the main factors to accident occurrence in this type of work. Limitations of the investigation: The study studied the reality found in a medium-sized city with precarious working conditions. Further studies can compare the work reality of other teams in cities of different sizes, with better working conditions. Other limitation of this work is the impossibility of work situation improvement and posterior tool application – a study with this magnitude is non-trivial and needs future research. Practical implications: The great achievement of this work is to demonstrate that FMEA - a tool that is widely used in maintenance management and product engineering - is able to identify and prioritize risks based on its preliminary risk index obtained - contributing to reduce the difficulty of index choices previously cited in literature and disseminate the FMEA utilization for employee safety and occupational health. Such a tool has a great capacity for quantitative description of the risks, showing that the FMEA is very useful in the work safety sector for the organization of correction plans. Originality / Value: The difficulties of using the tool mentioned in the available literature were minimized with the use of the reference table, showing that the use of FMEA can become faster and thus spread the tool for risk analysis.

FMEA (failure mode and effects analysis) with occupational safety approach is applied in the execution of water supply network maintenance in a medium size city in the state of Maranhao. This work shows that FMEA is an effective tool for risk prioritization in work process. The FMEA application with use of index reference table can become faster than application without reference table - and thus spread the tool for risk analysis. \u0000Design / Methodology / Approach: A photographic records was carried out in loco and the main risks to the workers were enumerated and based on the obtained data, a risk analysis was elaborated with the application of FMEA (Failure modes and effects analysis). \u0000Results: The maintenance services teams of the supply system are subject to a high risk of accidents caused mainly by the working conditions precariousness.
