Summary: Proper disposal of municipal solid waste is crucial in preventing land, air, and water pollution. This study proposes an integrated three-stage model to address waste collection, composting plant allocation, and vehicle routing, and applies it to the city of Bilaspur in India. Results indicate that decentralized composting plants are more cost-effective than centralized ones.

Summary: This study proposes a peer-to-peer energy sharing scheme to encourage user participation in energy management and reduce reliance on dispatchable resources by releasing flexibility at the demand side. By protecting privacy, users can make decisions based on local constraints while the microgrid operator announces sharing prices to meet coupling constraints. The research also develops a projection algorithm to calculate operating flexibility and presents a best-response based algorithm for market equilibrium.

Summary: This study develops and tests an integrated model to understand how gamification of mobile money payment can generate customer value through its social impact. The results show that gamified mobile money payment is positively related to social impact constructs and customer value propositions. This suggests that gamified mobile money payment can create substantial social impact and value for customers and service providers.

Summary: This study finds that terrorist attacks have an impact on the value of a firm's cash holdings, particularly for firms with excess cash. The results also show that the impact is stronger for firms facing more financial constraints, fewer agency conflicts, and better investment opportunities. Therefore, cash is a more valuable asset in high uncertainty environments such as terrorist attacks.

Summary: As Germany aims to increase the share of renewable energy consumption, congestion in the transmission grids will become a significant issue. This paper explores the integration mechanisms of Distributed Energy Resources (DERs) as a potential solution. The study investigates the load flexibility that DERs can provide in electricity markets and compares their performance in different scenarios. The findings suggest that while the value of optimal load-shifting may not be high enough to incentivize investment currently, it becomes promising in the future as renewable energy generation increases.

Summary: Assessing the environmental impacts of value chains is crucial for sustainability. This study evaluates the potential environmental sustainability of wood panel value chains in Austria and Slovakia using the PB-LCA framework. The results show that different sharing principles lead to different conclusions and strategies at both the value chain and national level.

Summary: This study investigates the impact of green innovation on firm value in Chinese heavy pollution listed companies from 2008-2017. It finds that increasing the proportion of green patent applications leads to a short-term devaluation of firm value. Both financial flexibility and analyst coverage partially mediate the impact of green innovation on firm value. Firms can reduce the negative impact of green innovation on firm value by increasing executive equity incentive and the management-employee pay gap.

Summary: This study investigates the location of construction waste centralized and decentralized processing facilities in new urban areas. The grey relational analysis method is used to determine the location of centralized facilities, and a multi-objective integer programming model is built to determine the location of decentralized facilities. The effectiveness of this model is verified using a case study of a new area in China. The results show that the proposed layout strategy can achieve low-cost, low-carbon, and low negative impact construction waste utilization.

Summary: Asphalt pavements experience ageing and moisture damage, leading to increased cracking susceptibility and decreased serviceability. The semi-circular bending (SCB) test is commonly used to assess the fracture resistance of asphalt mixtures. This study utilized the Illinois Flexibility Index Test (I-FIT) to investigate the impact of long-term ageing and moisture damage on the cracking resistance of asphalt mixtures modified with crumb rubber and plastic waste. The results showed that the a flexibility index (FI) values from the I-FIT were sensitive to the type of modifier and long-term ageing, but underestimated the impact of moisture conditioning on the fracture performance of asphalt.

Summary: Engineering systems are essential for providing services to society, but their performance is affected by uncertainties such as climate change and pandemics. Existing design methods often fail to recognize uncertainty and result in rigid systems. This study proposes a novel approach using deep reinforcement learning to analyze flexibility and improve system adaptability. The results show dynamic solutions parametrized by artificial neural network, with significantly improved economic value compared to previous solutions.

Summary: Ongoing risks from climate change have impacted global nomadic communities, increasing migratory movements. As a result, mobility considerations are important in energy systems planning for developing countries. Advanced Plug and Play control strategies allow easier interconnection of nomadic communities and the main grid. This study investigates the design and planning strategy of a mobile multi-energy supply system for nomadic communities, using Deep Reinforcement Learning Flexibility Analysis to address uncertainties and compare results with baseline designs.

Summary: This article studies the model for risk aversion in designing a flexible capacity expansion plan for a multi-facility system. The model uses a multi-stage stochastic programming problem and expresses risk aversion through Conditional Value-at-Risk (CVaR) and a mean-CVaR objective. The proposed algorithm optimizes the multi-stage problem using a decomposition algorithm and updates solutions via the subgradients of the function of cumulative future costs.
