Reviewer 3 1 It is necessary to include additional information for the data description Answer Thank you for your comment The necessary parameters for the experiments in Subsections 6164 were randomly generated in order to have enough instances to certify the quality of the MIPheuristic This information can be found on page 2324 lines 708726 In various parts of the article we highlight this point please see lines 741 795 892 etc No data prediction approach was adopted in this study On the other hand the data for the experiments in Subsection 65 Rio de Janeiro case study was obtained through interviews with a manager of a tourism company in Brazil and is therefore primary data This information is highlighted on page 34 on lines 10471050 and also on lines 10801082 Other data generation information and values are described in the article and in tables in the Appendix 2 Following the mathematical model is difficult due to a few notational mistakes Answer We appreciate the reviewers comment However we have done another detailed review of our mathematical model notation and equations and have not been able to identify them If there are still errors in the notation please let us know explicitly and we will correct them 3 The abstract should include significant findings and be structured clearly and easily It should briefly sum marize the papers main findings to help readers understand the research Answer We appreciate the reviewers suggestion and we agree We have inserted two sentences in the abstract regarding the sensitivity analysis carried out on the model parameters to identify important managerial insights A brief sensitivity analysis of some parameters of the model revealed important managerial insights Concentrating hotels and restaurants in the barycenter of tourist attractions increasing the visit and transfer time among attractions and reducing the planning horizon for the entire itinerary worsen the service level offered These findings certainly emphasize the practical contributions of the work 4 The papers title should be revised to reflect its content and be more concise and engaging accurately The authors should consider proposing a more suitable title that reflects the key findings of the research Answer We appreciate the reviewers comment We have shortened our title to a more comprehensive version An effective approach for biobjective multiperiod touristic itinerary planning 5 The research problem should be clear and concise to increase readability Answer Thank you for this suggestion We have changed the text on page 4 lines 7071 to focus specifically on the problem under study In this context the present study deals with a biobjective multiperiod period touristic itinerary plan ning based on the MIP model proposed in Silva et al 2018 for the single period day This paper proposes an effective optimization approach to design realistic tourist itineraries in multiple periods days including preferences and interests of users Multiperiod travel itineraries that consider visit sequencing dealing with constraints on travel time and stay at attractions time windows scheduling of hotels restaurants and the most convenient attractions to visit and in the optimal order are deter mined in a multiobjective perspective 8 Tour itineraries take into account two conflicting objectives i maximization of the quality of service offered or the level of customer satisfaction measured by the attractions visited route order level of hotels for accommodation and restaurants for lunch and ii minimization of the total distance traveled which can be converted into transportation costs or CO2 emissions levels 6 The authors should provide more insightful and actionable managerial insights based on the research findings and clearly articulate the practical implications of the research for managers and organizations Answer The question posed by the reviewer is important Managerial insights have been developed and discussed in Subsections 64 modifications in the parameters and Subsection 65 case study in Rio de Janeiro This subsection enriches the paper and reinforces the advantages of using an Operations Researchbased approach to support decisionmaking given the complexity of the problem under study We have improvedadded to the presentation in Subsection 64 lines 972981 where we describe which aspects are pertinent to managers in the area Thinking of even broader support for the decisionmakers a sensitivity analysis on some model parameters is performed with the intention to investigate how the solutions obtained vary in terms of the objective values and other important aspects for the tourist The scenarios were designed according to some strategies commonly adopted by tourism companies and the simulations aim to provide insights into which measures have the greatest impact on the objectives of the problem under study These analyses can provide managerial guidelines for travel agencies able to answer questions such as i what are the best strategies to localize hotels and restaurants ii What are the impacts on the solutions when shortening the planning horizon and keeping the same number of available attractions iii How much do some increases in attraction visit times and travel times between attractions affect the possibility of visiting all attractions We reiterate these findings and numerical results in the conclusions of the study lines 11551160 from Subsection 64 and 11611173 from Subsection 65 We believe that our work provides practical insights for managers and organizations in this sector 7 The introduction should provide a logical framework for the research with each paragraph flowing seamlessly into the next The authors should improve the coherence between paragraphs and offer more connections The introduction should also clearly highlight the research contributions and aim articulating the research question and its importance Answer We appreciate the reviewers comment Each paragraph has an ideainformation that begins and ends Following your recommendation connections have been introduced between the paragraphs in Section 1 as can be seen in lines 60 71 88 to establish a link and better flow of ideas In addition the importance of the research is highlighted using real data from specific websites Statista and GRTP when we present and discuss facts from the tourism industry in the world Please see Figures 1 and 2 and the discussion on lines 3759 Finally the objectives and contributions of this study are highlighted in lines 91103 We believe that our introduction is short However it contains enough elements to highlight the importance of the problem and describes the innovations introduced in this study 9 Reviewer 7 This

study in highimpact journals As a result we added six more references between 2021 and 2023 related to the topic of optimization in tourist itineraries Five of these references are from Expert Systems With Applications recently published showing that the topic is the subject of intense research The citation of these references are in lines 143 144 164 175 168 and 179 The five papers suggested by the reviewer were carefully analyzed by us We did not find a direct connection with four of them The topic reported the keywords and the solution approach do not connect with the present study ie it does not deal with tourist routing or use MIPheuristics Only the paper on https wwwsciencedirectcomsciencearticlepiiS095965262302629X has any relation to our work as the authors used a multiperiod dynamic electric vehicles production in a routing problem This work was cited on page 8 lines 250251 7 Please add more references from the target journal The number of references is very short for such a paper Please be at the knowledge edge Answer Thank you for this suggestion Our paper has a total 68 of references where 32 are from 20212023 Also we have now eight references from Expert Systems With Applications 8 Please add a research gap section Answer We appreciate the reviewers suggestion and we agree We have highlighted the gaps covered by this work in a subsection entitled

pointing out this issue We have inserted the classic reference Steuer and Choo 1983 that supports the Augmented Thebycheff method Please see lines 425 and 436 10 Please clarify which one of the assumptions is new in this area in the problem definition 11 Answer Thank you for raising this point We have rewritten the lines 7181 to insert the new concepts considered in this work In this context the present study deals with a biobjective multiperiod period touristic itinerary planning based on the MIP model proposed in Silva et al 2018 for the single period day Extending the previous study this paper proposes an effective optimization approach to design realistic tourist itineraries in multiple periods days including preferences and interests of users Multiperiod travel itineraries that consider visit sequencing dealing with constraints on travel time and stay at attractions time windows scheduling of hotels restaurants and the most convenient attractions to visit and in the optimal order are determined in a multiobjective perspective Tour itineraries take into account two conflicting objectives i maximization of the quality of service offered or the level of customer satisfaction measured by the attractions visited route order level of hotels for accommodation and restaurants for lunch and ii minimization of the total distance traveled which can be converted into transportation costs or CO2 emissions levels 11 Check the English presentation of this paper to remove typos and mistakes Answer The present version of the paper has been proofread in detail by a native English speaker Grammatical errors concordance and typos were eliminated Please see the Cover letter regarding the services attached 12 Findings limitations and recommendations of this paper can be discussed more in the conclusion section Answer Thank you for raising this point Our conclusion reports the findings of the work from the third paragraph onward Each paragraph introduces conclusions found in each subsection of the computational results 62 65 The limitations can be found in lines 11711180 as you can see The advantages of the proposed MIPheuristic over the related stateoftheart algorithm as evolu tionary algorithms include the goodquality solution in a reasonable computational time In addition the solution procedure developed is easy to understand and implement and is highly adaptable to varia tions in this problem such as adding restrictions prohibiting hotel changes over periods limiting costs mandatory attractions among others Modifications in the problem are more difficult to incorporate into metaheuristics and when they are achieved they may not perform as well as our method On the other hand one of the limitations of the proposed method is the increase in computational effort as the number of attractions grows However practical examples do not exceed B 100 attractions according to the specialist making it feasible to apply the proposed method 13 Please bring and focus on future research directions Answer The question posed by the reviewer is important We have again reviewed the paragraph of future research which we believe to be the most important based on the present study If the reviewer wishes to indicate other future research please let us know and we will be happy to include it in the article Please see lines 11811193 As future directions of research we aim to propose evolutionary metaheuristics to accelerate the generation of feasible solutions We also intend to develop valid inequalities for this model leveraging the proposed MIPheuristics to accelerate its computational performance further Moreover as certain parameters of the problem such as travel times and visit times are influenced by weather and traffic an interesting line of research would be to extend the problem modeling to cope with uncertain parameters and propose stochastic approaches to deal with it bringing the model and its solutions even closer to practical situations 12 Other advances in the modeling of this problem such as consideration of costs of attractions eg ticket purchase daily rates of hotels and lunch costs of restaurants opportunities for economies of scale when a tourist buys a larger package of attractions to visit penalties for changing hotels along the planning horizon as well as inclusions of other objectives eg reduction of CO2 emissions by using intermodality result in interesting tradeoff analyses between costs and customer satisfaction and would also be promising topics for future research 13
