Proposals are emerging not just for buildings but also for existing transport infrastructures that have needs/problems that can be met or addressed by such solutions. However, the economic feasibility of such sustainable solutions has not yet been clarified. This study presents a methodological approach to performing cost–benefit analyses of greening urban transport infrastructures at the separate financial, economic, and socioenvironmental levels. Infrastructure, user, and environmental dimensions are also assessed. Whole life cycle costs and socioenvironmental benefits are considered together. The methodology is applied to one of the main stations in Lisbon, Portugal: Entrecampos Railway Station. Five different case study alternatives for the station’s retrofit with green infrastructures are compared to its current situation. The cost–benefit analysis demonstrated that all five greening alternatives are economically feasible. For a 50-year life cycle and a 3.36% discount rate, the net present value ranged between EUR 734,700 and EUR 7,733,279. A sensitivity analysis was also performed, revealing a high degree of influence of discount and inflation rates, recreation, aesthetics improvement, well-being, and the station noise reduction on the net present value, ranging from 1.5 to 9%.","PeriodicalId":49210,"journal":{"name":"Engineering Economist","volume":"64 1","pages":"167 - 190"},"PeriodicalIF":1.2,"publicationDate":"2019-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/0013791X.2018.1470272","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48450051","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This article evaluates dock-specific resource allocation strategies to improve port preparedness by integrating a dynamic risk-based interdependency model with weighted multicriteria decision analysis techniques. A weighted decision analysis technique allows for decision makers to balance widespread impacts due to cascading inoperability with certain industries that are important to the local economy. Further analysis of the relationship between inoperability and expected economic losses is explored per commodity flowing through the port, which allows an understanding of cascading impacts through interdependent industries. Uncertainty is accounted for through the use of probability distributions of total expected loss per industry that encompass the uncertainty of the length of disruption and severity of the impact that is mitigated by alternative strategies. A set of discrete allocations options of preparedness plans is analyzed in a study of the Port of Catoosa in Oklahoma along the Mississippi River Navigation System. The economic loss analysis showed that the integration of multicriteria decision analysis helps in prioritizing strategies according to several criteria such as gross domestic product (GDP) and decision maker risk aversion that are not typically addressed when strategies are prioritized according to the average interdependent economic losses alone.","PeriodicalId":49210,"journal":{"name":"Engineering Economist","volume":"64 1","pages":"346 - 367"},"PeriodicalIF":1.2,"publicationDate":"2019-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/0013791X.2019.1580808","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41625537","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In fact, the literature and empirical evidence suggest a bias toward favoring concessionaires, although there are well-known examples of harmful unilateral decisions by governments. This article establishes a distinction between structural renegotiations (with changes in the risk-sharing agreement) and nonstructural renegotiations (without shifting risk) and analyzes the implications of structural renegotiations in a road concession by comparing the ex ante and ex post financial implications for government, concessionaire, and users. The selected project is one that started as a shadow toll and was later changed to real toll. The analysis shows that the renegotiation essentially transferred costs to the users. The financial burden for the government decreased and the internal rate of return (IRR) of the concessionaire increased slightly although the overall risk profile of the concession decreased. The users supported a 40% higher cost, and the system gained an additional cost component (the electronic tolling system). Overall the global financial costs increased 40% when compared with the initial regime. The article also sets out some discussions and implications for policymakers.","PeriodicalId":49210,"journal":{"name":"Engineering Economist","volume":"64 1","pages":"116 - 141"},"PeriodicalIF":1.2,"publicationDate":"2019-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/0013791X.2018.1559384","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45113063","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent failure instances of salary administration demonstrate the exiguity and/or inapplicability of scientific research in this area. This research considers the core aspects of theoretical salary administration while complying with the recent competitive working environment. In this article, a mathematical optimization approach that recognizes the significance of performance and potential to future promotions of employees is proposed to find the optimal salary increase amounts and to set an advantageous schedule for salary increases. The two objectives are combined with a weight, and a sensitivity analysis shows the impact of the weight on both objectives to provide managerial guidance. The resulting raise amounts satisfy both internal alignment and external competitiveness conditions and represent employee performance and potential for promotion. The proposed mixed integer programming problem can be solved with commercial solvers quickly, even for rather large instances. The short computational time directly addresses the challenge raised by the current trend that more enterprises hire a large number of exempt employees. Additionally, two cases are presented with detailed data collection to illustrate the applications and limitations of the proposed model.","PeriodicalId":49210,"journal":{"name":"Engineering Economist","volume":"64 1","pages":"115 - 97"},"PeriodicalIF":1.2,"publicationDate":"2018-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/0013791X.2018.1528408","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47592056","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
