Fair strategies in the supply chain planning are important to the sustainability development of supply chains. This work addresses the fairness-oriented multi-objective optimization of the production, distribution and capacity planning problem of multi-period, multi-product global supply chains under uncertainties, to optimize cost, responsiveness and customer service level, simultaneously. A fuzzy-based optimization model is established and transformed into a deterministic mixed integer linear programming (MILP) formulation, in which a new formulation method is developed to transform the variables with fuzzy parameters in the index into a definite form. In addition, to achieve sustainable development of the supply chain, Nash bargaining method is used for the proportionally fair strategies between the multiple objectives. Finally, a numerical case is used to demonstrate the applicability of the proposed model and solution approach. The computational results are shown to be Pareto-optimal. The fair solutions under different allowed degrees of uncertainty are compared through the Monte Carlo simulation. In addition, the obtained solutions are shown to be fairer than those from alternative solution method and capacity expansion strategy.

As a Multi-Attribute Decision Making problem, operation performance evaluation of high-speed railway networks (OPHSRN) is critical in actual management and operation practice. In this paper, the evaluation indexes including technology, economics, coupling and coordination degree are established considering economic characteristics. An Inclusive Attribute Value Function (IAVF) is proposed to calculate attribute value. The Swing Weighting (SW) method, the Entropy Weight Method (EWM) and Scatter Degree Method (SDM) are used to calculate the weight value, respectively. The Weighted Sum (SW) and Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS) are used to aggregate the decision information, respectively. Sensitivity analysis of each attribute is conducted. The stability of SW, EWM and SDM are analyzed. The results show that the optimal number of experts is 5 when apply SW. SDM is more stable than EWM, TOPSIS has more advantages in reflecting the differences among attribute values. When applying IAVF to calculate attribute value, the selections of weight methods and decision information aggregation methods have little influence on the final evaluation results. Finally, a case study is conducted by using the collected operation data of HSRN in Sichuan (in Western China), Hubei (in Central China) and Fujian (in Eastern China) provinces.

This paper investigates a milk supply chain encompassing a milk collection station and a manufacturer. The station acquires milk from farmers, performs quality control to detect non-toxic adulterants, stores, and sells the mixed milk to the manufacturer at wholesale prices. However, the station might introduce toxic additives to enhance product appearance and stimulate demand. The manufacturer further processes the milk and sells it to consumers. In an endeavor to curb both toxic and non-toxic adulterations, the government employs regulatory measures and subsidy schemes. The impact of government regulations on the various segments of the supply chain is analyzed using game theory in this study. Additionally, the study explores the influence of diverse contractual arrangements on decision variables and player profit functions. To this end, four scenarios are analyzed: decentralized structure, cost-sharing contract, safety guarantee contract, and hybrid contract. The findings reveal that intensifying deterrent factors not only enhances product safety but also leads to a reduction in non-toxic adulterations. It is observed that the cost-sharing contract can augment the profitability of all supply chain members. Furthermore, the study concludes that the allocation of inappropriate subsidy levels can induce increased additive usage by members, which contradicts the government's objectives in providing subsidies.

With the rapid pace of urbanization and increasing economic specialization, the mental health of middle-aged and elderly adults is becoming an urgent concern, particularly in the wake of challenges such as rising unemployment and the aftermath of the COVID-19 pandemic. While high-speed rail (HSR) networks have played an increasingly significant role in regional economic development, their impact on public health—especially mental health—remains underexplored. The present paper is the first study targeting on mental health of the expansion of HSR network among the particular group, i.e., the middled-aged and elderly adults who are with accumulative wealth and losing health. Leveraging Staggered Difference-in-Differences (DID) and high-dimensional fixed effects (HDFE), this study investigates the cumulative effects of HSR development on individuals’ mental health using micro-panel data from the China Health and Retirement Longitudinal Study (CHARLS) for the years 2011, 2013, 2015, and 2018. After addressing endogenous issues, our findings suggest that both the introduction and further operation of HSR services positively influence the mental health of this demographic group. These results hold up under a series of robustness checks. Furthermore, the mechanisms behind this improvement include increased mobility for social visits, enhanced regional green technology innovation, and reduced pollution levels. The positive impact is particularly pronounced among individuals who are not yet retired and remains consistent across various residential and domicile settings. This paper offers a novel contribution to the growing body of literature on HSR network expansion and public health, providing critical insights for future transportation and urban planning initiatives.

Previous studies have highlighted the role of institutions among the drivers that favour the transition from the linear to the circular economy model. However, these studies tend to exclude the institutional supply chain and its correct functioning (i.e., ‘good administration’). Thus, this study aims to analyse the effect of good administration on the two main phases of the circular economy paradigm in the waste sector in Italy. In this context, we propose an original good administration index (GAI) of public administration whose purpose is to capture the financial and organisational components of public administration staff. The analysis was conducted on data from 103 Italian provinces from 2008 to 2019. The results show that the GAI is key for achieving the upstream and downstream goals of the circular economy in the waste sector.

In this paper, input‒output analysis is applied to assess the value-added scale of smart agriculture, with an emphasis on industrial linkages and final demand. The results reveal that smart agriculture constitutes 5.58 % of the agricultural sector and only 0.47 % of GDP in China. Although the value-added contribution of smart agriculture remains modest in comparison with that of traditional agriculture, it demonstrates strong integration with digital industrialization sectors and low dependency on inputs or demand growth from other industries. In terms of final demand, sensitivity analysis shows that smart agriculture is a consumption-dependent industry; however, the promotion of smart agriculture associated with various final demands remains limited, with the expansion of final demand predominantly benefiting traditional agriculture. The transformation of the industrial structure has been a key driver of the growth of smart agriculture since 2012. Between 2012 and 2020, changes in the structure of intermediate goods and final demand collectively contributed to a 44.9 % increase in the scale of smart agriculture.

This study investigates the impact of highway improvements on new firm location in underdeveloped regions. Both a two-way fixed-effects model and a long-difference model have been employed, using panel data from counties across Central and Western China, earmarked for national-level poverty eradication, for 2012 and 2020. The results show that highway improvements in underdeveloped regions exert a siphoning, rather than diffusion, effect on firm location in the short and long term. This effect, however, dissipates under four scenarios: higher resource endowment, larger market size, greater spatial distance from large cities, or smaller economic disparity with large cities. This indicates that firm location is also influenced by the interplay of “agglomeration” and “dispersion” in developed regions, and “exclusion” and “attraction” in underdeveloped regions after highway improvements. Additionally, the impacts of different highway classes vary, with inter-regional highways mainly leading to the siphoning effect, and intra-regional highways exerting a diffusion effect under the abovementioned scenarios. Finally, the siphoning effect is more apparent in capital- and technology-intensive industries than in labor-intensive industry, reflecting the varying development characteristics of these industries.

Currently, the redevelopment of urban villages in China is facing increasingly severe challenges. Industry-oriented Urban Village Redevelopment Projects (IUVRP) represent a potentially enormous new development mode, requiring timely research into IUVRP operation and the behaviors of stakeholders involved. Employing evolutionary game theory and complex network theory, this study assesses behaviors of key stakeholders: the local government, enterprises, and village collectives. Results show the following: (a) There are three stable strategy sets, (0, 0, 0), (0, 0, 1), and (1, 0, 1), with (1, 0, 1) as the Pareto optimal strategy of {local government supervises, enterprises do not act opportunistically, village collectives cooperate positively}. (b) Enterprises exhibit a propensity for choosing not to act opportunistically. Enhancing the constraint of the local government and reducing cooperation costs of village collectives are vital. (c) IUVRP is suitable for urban villages with a certain scale. Subsidies and income positively influence villagers' participation. Relocation costs, hitchhike benefits, and reputation loss are negatively correlated with villagers' willingness to participate. Increasing penalties is more conducive to fostering villagers’ willingness to participate in IUVRP than setting rewards. This study provides a clear summary of the mode of the emerging IUVRP and conducts a progressive analysis on behaviors of stakeholders, offering a new analytical framework for project behavioral research of stakeholders.

This paper introduces the Time-Definite Hub Line Location Problem (TD-HLLP), an innovative extension to the Hub Line Location Problem (HLLP) which aims to capture the time restrictions usually observed in delivery time on real logistics settings. To address this important gap in existing Hub Line models proposed in the literature, we propose a novel formulation that relies on a set-packing approach to enhance efficiency in time-sensitive deliveries. We conduct a thorough numerical analysis of the TD-HLLP behavior under various operational scenarios to explore the intertwined relationship between the number of vehicles performing the inter-hub transportation, the service level (i.e., the promised longest delivery time), and the network cost. Our results provide valuable information to regional transport managers who commit themselves to service constraints on delivery times.

Closed-loop supply chain systems have gained significant attention in recent years due to their potential for environmental and economic benefits. This study unveils customer-oriented economic measures and ensures environmental sustainability in a closed-loop dual-channel supply chain (CL-DCSC) model system comprised of a single manufacturer and retailer. This investigation combines closed-loop aspects of collecting used products from numerous consumers with dual-channel processes incorporating the uncertainty in market demand and raw-material cost. The proposed model includes the return rate of used products as a crucial factor in addition to considering wholesale, retail, and online sale prices for making informed decisions. This study utilizes an uncertain parameter defuzzification technique with fuzzy possibility measures to globally maximize the expected net earnings of the whole supply chain (SC) in a centralized decision-making scenario and the expected net earnings of every participant in a decentralized decision-making scenario. Extensive numerical simulation reveals that the CL-DCSC model corresponds to stakeholders’ desired eco-friendly, customer-oriented, and profitable strategy in the centralized decision-making scenario. The study demonstrates that adopting a two-part tariff (TPT) contract can facilitate rational decision-making among stakeholders, aligning their interests with the centralized strategy. Furthermore, this study provided a mathematical approach for measuring contract fairness, Pareto improvement, and coordination efficiency. The outcomes confirm that the contract is fair, facilitates Pareto improvement, and effectively coordinates the CL-DCSC. The model emphasizes the importance of developing a CL-DCSC framework, suggesting that collaborative partnerships are more beneficial than competitive approaches. The findings encourage businesses to prioritize sustainable practices, such as recycling and product returns, which can lead to cost reductions and improved profitability. Understanding and integrating consumer preferences into SC strategies can enhance customer satisfaction and loyalty, benefiting overall SC performance.

The model emphasizes the importance of developing a CL-DCSC framework, suggesting that collaborative partnerships are more beneficial than competitive approaches. The findings encourage businesses to prioritize sustainable practices, such as recycling and product returns, which can lead to cost reductions and improved profitability. Understanding and integrating consumer preferences into SC strategies can enhance customer satisfaction and loyalty, benefiting overall SC performance.</div></div>","PeriodicalId":22033,"journal":{"name":"Socio-economic Planning Sciences","volume":"99 ","pages":"Article 102182"},"PeriodicalIF":6.2,"publicationDate":"2025-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143550787","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
