There are several alternatives for the quantification, detection and monitoring of water losses. However, in general, water companies have budgetary and other constraints that hinder implementation. Therefore, this paper presents a model to aid the selection of a subset of preventive maintenance actions to control water losses while accounting for the water companies’ restrictions. The model combines an additive multi-attribute value analysis by applying the SMARTER method to evaluate alternatives with Integer Linear Programming (ILP). The model shows to be efficient in order to achieve a portfolio of preventive maintenance actions, particularly when the decision maker considers that, there is a compensation for attribute evaluations.","PeriodicalId":263089,"journal":{"name":"Production Journal","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115343146","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For that purpose, we develop a novel corporate sustainability factor and test the extent to which this factor is priced in an augmented four-factor version of the traditional Fama & French (1993) asset pricing model. The corporate sustainability factor is based on a zero-investment portfolio which is long in stocks with high sustainability and short in stocks with low sustainability. We use data on the Brazilian stock market to estimate alternative model specifications with different combinations of four explanatory variables: the corporate sustainability premium, the market risk factor premium, the size factor premium and the book-to-market factor premium. Our results indicate that corporate sustainability is priced and helps to explain the variability in the cross-section of expected stock returns.","PeriodicalId":263089,"journal":{"name":"Production Journal","volume":"165 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131060181","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to assess the integration of sustainability into project management. The methodological approach used was an exploratory study with a qualitative approach, conducted in six projects in the food service companies. Data were gathered through project documents and semi-structured interview with the projects’ stakeholders. The results of the pilot tool for the systematic evaluation of sustainability in projects and its practical application are described. The paper concludes that the pilot tool proposed presents a systematic logic with applicability for assessing sustainability in the context of project management. Finally, the results of the assessment show that the economic dimension still overlaps the environmental and social dimensions.","PeriodicalId":263089,"journal":{"name":"Production Journal","volume":"120 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123506151","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Taking account the other activities the farm performs in its production strategy can help understanding the decision on the adoption of new agricultural technology. This paper aims to evidence the existence of synergic effect resulting from the joint adoption of feedlot and traceability certification of beef cattle in Brazil. A sample of 84 beef cattle farms provided data to test hypotheses by using an OLS regression model. A measure of performance – revenue – is regressed on variables representing both isolated and joint adoption of capital-intensive production system and traceability. The results suggest the existence of synergic effect when joint adoption takes place. Joint adoption is influenced by a set of management practices, such as forward contracts, training of employees and zootechnical performance control, which are shared by both capital-intensive production systems and traceability.","PeriodicalId":263089,"journal":{"name":"Production Journal","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129128586","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such changes are related to fusions and acquisitions, as well as the largest market opening to foreign banks. The objective of this paper is to analyze, by applying the bootstrap DEA, the efficiency of banks in Brazil in 2010-2013. The methodology was applied to 30 largest banking organizations in a financial intermediation approach. In that model, the resources entering a bank in the form of deposits and total assets are classified as inputs and besides these manual labor is also considered as a resource capable of generating results. For the output variable, credit operations represent the most appropriate alternative, considering the role of the bank as a financial intermediary. In this work, the matter of the best classification among retail banks and banks specialized in credit has little relevance. The low relevance in this type of comparison is a result of analysis by segments (segments were analyzed separately). The results presented here point to an average level of efficiency for the large Brazilian banks in the period. This scenario requires efforts to reduce expenses but also to increase revenues.","PeriodicalId":263089,"journal":{"name":"Production Journal","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125708841","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover, different disciplines and knowledge areas, with particular approaches and methodologies, contribute with this type of production. A particular knowledge area named Web Engineering was developed to focus on these questions; however, it is not consolidated yet. This work aims to present guidelines to the definition of the Web applications production process, from a systemic approach, where the different disciplines, roles and activities are correlated, in the conception phase. The research method utilizes tree cases studies and two action-researches to create a theoretical model through analysis of particular situations. The work identifies a design space formed by the dimensions Form, Function, Information and Technology, related to the main disciplines involved in Web applications production: Design, Software Engineering and Communication & Media. According to the design standard used, it is concluded that there is a best fit for the production process, oriented by one or more dimensions of the design space, allowing a quick evolution of the project to the expected quality level.","PeriodicalId":263089,"journal":{"name":"Production Journal","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116385868","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, postponement strategy has never been used by researchers in procurement to reduce cost and to enhance overall flexibility of the process. This paper gives a new concept of postponement, called procurement postponement, which is considered to be effective for the multi-product, assemble-to-order (ATO) system. A two-stage integrated approach of sustainable procurement and postponement method is proposed for the multi-product ATO production system to deal demand uncertainty, green house gas (GHG) emission, reliability of supply, level of disassembly and social issues of supplier selection with intuitionsitic fuzzy analytic hierarchy (IF-AHP) and multi-objective genetic algorithm (MOGA). Case study of an Indian company is discussed to use the proposed method by cost-emission-decision matrix.","PeriodicalId":263089,"journal":{"name":"Production Journal","volume":"2 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116399749","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To achieve this goal, a literature review was carried out for a subsequent contrast with the national academic researches that use action research and show its uses. Identified these similarities, a documentary research was carried out in academic papers published in the National Meeting of Production Engineering (ENEGEP) – from 1996 to 2010. The content analysis was the strategy used for data analysis and NVivo  software was used for its treatment. As a conclusion of the research, it can be stated that the use of action research in the Brazilian Production Engineering distances itself from epistemic precepts associated with it.

This approach is called “packaging logistics”. Another managerial approach that is related to efficiency and sustainability is the implementation of “meta-standards” (ISO 9000 and ISO 14000). As both “packaging logistics” and “meta-standards” can contribute positively towards supply chain efficiency and sustainability, it becomes relevant to examine the relationship between them. In this study, we explore the potential relation between “meta-standards” (ISO 9000 and ISO 14000) and the implementation of the key aspects of “packaging logistics”. In addition, we explore the relation between “packaging logistics” and aspects of performance. This is accomplished through an exploratory study of the packaging design process of Spanish manufacturers in the food industry.","PeriodicalId":263089,"journal":{"name":"Production Journal","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131297713","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
