Integration of Flexibility in Reverse Supply Chain Planning Process
by Kanchan Das
Abstract: This research formulates reverse supply chain (RSC) flexibility criteria and integrates them in a closed loop supply chain planning model for improving overall business performances and sustainability. Proposed RSC flexibility criteria include, a) channel selection strategy to collect customer returned products (returnable); b) product design and recovery strategy to recover components, modules, and products from returnable; and c) product categorization strategy for marketing new, recovered, and mixed quality level product. Each flexibility criteria is formulated independently to provide options to supply chains (SCs) to incorporate all or select ones in their planning process. The benefits, applicability, and integration procedures of proposed flexibility considerations are demonstrated through a numerical example.
Keywords: Reverse supply chain; flexibility formulation; collection channel; mixed integer programming model; recovery services; mixed quality level product.

Abstract: The construction industry in Australia has grown significantly in the past two decades in the wake of population growth, migration and expansion in the tertiary education industry. The growing population has necessitated extensive property development, better public transport and improved infrastructure. To achieve all of this, construction activities have been on the rise; resulting in significant growth in construction and demolition (C&D) waste generation. However, the management of C&D waste has presented issues that have proven impact on the Australian society, environment and economy. Therefore, this review study is conducted to investigate how C&D waste is dealt in eight jurisdictions of Australia. This study reviewed the
strategies recommended in waste strategy documents in these jurisdictions. Particularly, the study reviewed waste recycling and recovery targets, illegal
dumping and stockpiling, extended producer responsibility, the definition of waste versus resource; use of C&D recycled waste and energy from waste extraction. The results of this review have provided an insight into the approach taken in the Australian context to deal with C&D waste stream.

Big Data Analytics: Classification and Solution for Soil and Fertilizer System
by Raghu Garg, Himanshu Aggarwal
Abstract: Soil is one of the most important factors for the growth of plants. It carries various nutrients like water and certain contents of air which are essential for plant nourishment. At times over exposure becomes the root cause for the degradation of an otherwise fertile soil. In present times fertilizers are given the responsibility to maintain the productivity that we yield from the soil. The method prevalent to determine the quality of the soil is known as soil analysis. Soil analysis generates an estimation of the unstructured data through the process of examining the defined soil. The specimens of a wide spectrum of soils are tested in the laboratories in order to develop heaps of agricultural data. During our research work different machine learning algorithm using big data analysis are used to detect the fertilizer recommendation classes through defined soil nutrition composition. The reports are collected from Tata soil testing laboratories for experiment. Stochastic Gradient Descent (SGD) and Artificial Neural Network (ANN) are the classification methods that are compared in this paper. The performance measures inclusive of the accuracy and area under curve (AUC) are exercised to determine efficiency of classification model. Experiments show that the SGD performs a lot better then artificial neural network when it comes to accuracy, AUC and pace. The ANN is outdone by SGD with linear regression. The percentage of overall accuracy and AUC values of SGD are 88% and 86% respectively. The overall accuracy and AUC using ANN is 80% and 79% respectively. The results also reflect that SGD with linear regression are feasible in accurate recognition of the fertilizer recommendation classes.

Optimizing the proportion of pure and mixed culture in inoculum to enhance the performance of microbial fuel cells
by Dipak Jadhav, M.M. Ghangrekar
Abstract: Single chamber microbial fuel cells (MFCs) made from ceramic pots, forming anodic chamber, were inoculated with different proportions (v/v) of Shewanella putrefaciens and mixed-anaerobic sludge, viz. 100:0% (MFC-1), 0:100% (MFC-2), 10:90% (MFC-3), 30:70% (MFC-4) and 50:50% (MFC-5). Performance of these MFCs was evaluated using different electrochemical analyses. Due to specific substrate-selectivity, MFC-1 showed lower power (1.22 W.m-3) than MFC-2 (2.15 W.m-3). Power performance increased from 2.21 (MFC-3) to 2.56 W.m-3(MFC-4) with increased fraction of S. putrefaciens from 10 to 30% in the inoculum, and power density further enhanced to 3.1 W.m-3 in MFC-5 inoculated with equal-fraction of S. putrefaciens and mixed sludge. Bioelectrochemical analyses showed higher electron transfer rate and lower charge-transfer resistance in MFC-5 due to synergy between both the inoculums and promoted the electron transfer rate at anode. Thus, inoculation of MFC with equal-fraction of mixed-anaerobic sludge and S. putrefaciens showed effective bio-augmentation to reduce the start-up time and to improve the anodic bioactivity and power generation from MFC.

by Yan Zhang, Jian Yu, Yiying Fang, Sang-Bing Tsai, Quan Chen
Abstract: As China transitions towards high-quality economic development, exploring and improving the green transport efficiency of airlines on the premise of environmental constraints is important for the country's industrial transformation. In this paper, the slack-based model (SBM) and meta-frontier model were used to measure the efficiency and efficiency gaps of Chinese airlines from 2001 to 2016 under different, as well as identical production frontiers. The paper also analyzed the issue of inefficiency caused by the mismatch of airline factor inputs. The results showed that: first, the overall efficiency of airlines in China followed a W-shaped change; second, private joint-venture airlines had the highest efficiency and the efficiency increased relatively quickly; and, third, the allocation redundancy factor input was an important reason for the airline inefficiency, and obvious improvement was noted regarding issues pertaining to personnel redundancy and fuel consumption redundancy. Based on the research findings, countermeasures are proposed to improve the efficiency of airlines in China so as to achieve high-quality development.
