TL;DR: The proposed ELECTRE-based method enriches the spectrum of multiple criteria decision analysis approaches that can be used to effectively approach the problem of the 3PRLP selection, which was so far dominated by Analytic Hierarchy Process and TOPSIS.
Abstract: Pressure from legislation and customers has motivated companies to consider reverse logistics (RL) in their operations. Since it is a complex procedure that requires an adequate system, the recent trend consists in outsourcing RL to third-party reverse logistics providers (3PRLPs). This paper provides the background of sustainable triple bottom line theory with focus on economic, environmental, and social aspects under 3PRL concerns. The relevant sustainability criteria are used in a case study conducted in cooperation with an Indian automotive remanufacturing company. To select the most preferred service provider, we use a hybrid method combining a variant of ELECTRE I accounting for the effect of reinforced preference, the revised Simos procedure, and Stochastic Multi-criteria Acceptability Analysis. The incorporated approach exploits all parameters of an outranking model compatible with the incomplete preference information of the Decision Maker. In particular, it derives the newly defined kernel acceptability and membership indices that can be interpreted as a support given to the selection of either a particular subset of alternatives or a single option. The proposed ELECTRE-based method enriches the spectrum of multiple criteria decision analysis approaches that can be used to effectively approach the problem of the 3PRLP selection. As indicated by the extensive review presented in the paper, this application field was so far dominated by Analytic Hierarchy Process and TOPSIS, whose weaknesses can be overcome by applying the outranking methods.

TL;DR: The results indicate that integrating the strategic decisions of selection of logistics partners with the operational flow planning decisions can immensely improve the sustainable performance value of the SC network and secure reasonable profits.
Abstract: Due to rising concerns for environmental sustainability, the Indian electronic industry faces immense pressure to incorporate effective sustainable practices into the supply chain (SC) planning. Consequently, manufacturing enterprises (ME) are exploring the option of re-examining their SC strategies and taking a formalized approach towards a sustainable partnership with logistics providers. To begin with, it is imperative to associate with sustainable forward and reverse logistics providers to manage effectively the upward and downstream flows simultaneously. In this context, this paper proposes an integrated SC network for the evaluation and selection of forward distribution partners (FDP) and third party reverse logistic providers (3PRLP) from a sustainable perspective of an Indian electronic ME. The sustainable evaluation of the logistic partners is performed using fuzzy analytic hierarchy process and the technique for order performance by similarity to ideal solution. The integrated logistics network is modeled as a bi-objective mixed-integer programming problem with the objective of maximizing the profit of the manufacturer and maximizing the sustainable score of the selected forward and reverse logistics providers. The novelty of the study is its ranking of the FDPs and 3PRLPs on the economic, environmental, and social dimensions of sustainability and the simultaneous integration of logistics outsourcing decisions for the forward and reverse flow of products. Goal programming approach is utilized to capture the trade-off between the conflicting objectives and to attain a satisfying solution to the bi-objective problem. The results indicate that integrating the strategic decisions of selection of logistics partners with the operational flow planning decisions can immensely improve the sustainable performance value of the SC network and secure reasonable profits. The managerial implications drawn from the result analysis provide a sustainable framework to the ME for enhancing its corporate image.

TL;DR: This study addresses the problem of inventory control and pricing in a three-echelon supply chain with deteriorating items and a compensation policy is used for evaluation of the benefits and losses related to non-integrated policies.
Abstract: This study addresses the problem of inventory control and pricing in a three-echelon supply chain (SC) with deteriorating items. It is assumed that deterioration and demand and functions of the manufacturer and retailer are probabilistic, and relationship between SC members is according to the “delayed equal-sized shipment inventory policy”. One integrated policy and three non-integrated ones are formulated, and the conditions to obtain the solution are discussed. Through the simulation and sensitivity analysis on an extended numerical example, some managerial implications are presented. Moreover, a compensation policy is used for evaluation of the benefits and losses related to non-integrated policies.

TL;DR: The findings show the efficiency of the developed model, and based on the considered example, “Eco-efficiency” can be regarded as an effective strategy.
Abstract: One of the most essential topics for the present and future generations is sustainability. Today, because of threats made by traditional and old manufacturing practices, sustainability has become an essential topic in manufacturing companies. Attaining a sustainable manufacturing process requires making decisions about the strategies of manufacturing. In this paper, a novel integrated model is developed to evaluate sustainable manufacturing strategies. The proposed model is based upon two multi-criteria decision-making (MCDM) methods: WASPAS (Weighted Aggregated Sum Product ASsessment) and SECA (Simultaneous Evaluation of Criteria and Alternatives). Due to the uncertainty of evaluation process, we use interval type-2 fuzzy sets (IT2FSs). An example of evaluating sustainable manufacturing strategies is presented, and a sensitivity analysis is carried out for illustration of the developed approach and validation of it. The findings show the efficiency of the developed model, and based on the considered example, “Eco-efficiency” can be regarded as an effective strategy.
TL;DR: The methodology proposed can guide organizations when developing more specific GSD plans through identifying the poor suppliers and the weak areas and use of development priority number to effectively assess suppliers’ green capability.
Abstract: Green supplier development (GSD) is an important operational strategy that significantly contributes to environmental performance of the supply chain. However, green supplier evaluation for development, the first step in green supplier development, has not been widely reported in the literature. This article aims to develop a green supplier evaluation methodology for supplier development. Poor suppliers set and weak areas of each supplier are identified so that green supplier development practices can be implemented. This study proposes an environmental evaluation methodology based on environmental performance and environmental practices and use of development priority number to effectively assess suppliers’ green capability. A novel interval-valued intuitionistic fuzzy numbers based reference-neighborhood rough set approach is then used to identify the poor supplier set and suppliers’ weak areas. The feasibility of this methodology is illustrated through a case study in a large chemical company. The methodology proposed can guide organizations when developing more specific GSD plans through identifying the poor suppliers and the weak areas.
TL;DR: This paper identifies root causes for the background traffic and evaluates Apps’ behavior with respect to impacts of TCP connection flow on Smart phone battery, and proposes a solution for such TCP closures at the client side with the objective of controlling unwanted TCP retransmissions.
Abstract: Applications (Apps) in Smart devices make our life connected to Internet all the time. Many of the Apps like Google Apps, Facebook, and Twitter generate periodic background traffic. Due to this background traffic, battery continuously drains in Smart Phones. In this paper, we identify root causes for the background traffic and evaluate Apps’ behavior with respect to impacts of TCP connection flow on Smart phone battery. We have conducted extensive experiments and collected data from various operator networks in different countries. We observe that TCP delayed closures not only extend radio wake up time but also lead to prolonged retransmissions. These prolonged retransmissions lead to severe battery drain problem. We propose a solution for such TCP closures at the client side with the objective of controlling unwanted TCP retransmissions. Our proposed solution is energy efficient, light weight, application agnostic, and a client only solution which makes deployment easier. Our solution has been evaluated for Android devices such as Samsung Galaxy S6, S7 variants, J7, and the Tizen device such as Samsung Z3. We have found that our solution consistently achieves 10 to 20 percent of power usage reduction irrespective of varying network and traffic conditions. We provide detailed experimental results considering various corner cases and also present the implementation architecture of our proposed solution.
TL;DR: In this paper, the authors developed a better understanding of how transportation system factors affect city housing markets by conducting a thorough literature review and testing their relevance using a quantitative methodology and a sample of 317 Vilnius residents.
Abstract: The purpose of this paper is to develop a better understanding of how transportation system factors affect city housing markets. The goal was to show that identifying these factors alone is not enough without also examining their effects and variations according to the housing location.,Transportation system factors were identified by conducting a thorough literature review. The factors’ relevance was tested using a quantitative methodology and a sample of 317 Vilnius residents. This city was next divided into three zones, and data collected from 18 real estate experts was subjected to qualitative analysis. The analytic hierarchy process was then applied to identify transportation system factors’ level of impact and dynamics by the housing location.,The results show that the factors affect the housing market in question but that these effects vary by the housing location and the most critical factors differ for each city zone.,Only data on Vilnius were used. Further research is needed to compare transportation factors’ dynamics in multiple cities.,Priorities in transportation system improvements should be assessed to facilitate sustainable urban development and enhance the residents’ quality of life. Housing market regulations can only be successful if investment in transportation systems is allocated purposefully and coherently.,This research went beyond identifying transportation system factors by employing a broad, systematic approach to clarifying potential options for regulating housing markets through transportation system projects.
