A game theoretic approach to optimize multi-stakeholder utilities for land acquisition negotiations with informality

To combat the critical stresses of rising urbanization, the government acquires land from private owners using the power of eminent domain. This land assembly causes negative externalities such as increasing social tension and injustice that may impose a long-term threat to stability and sustainable development. Therefore, there is a need to make the land acquisition process more transparent and just. Considering the unique Indian context where informality has a strong presence, we propose an approach based on game theory that models the bargain through a three-stage Nash equilibrium game. Four agents – the government, the private developer, the landowner, and the free rider – are considered. We provide conditional solutions for the generalizable Case and proceed to model different stakeholder behavior patterns through two utility functional forms – linear and exponential. In the linear case, we find that the free rider obtains half of the revenue of the project, whereas the landowner gains between one-fourth and one-half of the revenue. Thus, we highlight the undeniably crucial role free riders play in land acquisition negotiations. However, closed form solutions cannot be obtained for the exponential form, due to which we use simulations to demonstrate a solution procedure. We conclude by stating that the proposed model can be useful in formulating future land policies in a sustainable and inclusive manner, with optimal utility derivations for all concerned stakeholders. Our model can also be extended to other spatial contexts where informality features heavily in the land market, especially in the Global South.

关于我国物业管理模式的反思与再造

物业管理作为一种专业化、社会化、企业化的不动产管理模式,在我国已走过了30年的历程。但是,迄今为止,我国尚未形成真正的物业管理市场,没有形成成熟的符合我国国情的物业管理模式和管理制度。认为如不尽快探索出符合我国国情、民情和房屋建筑管理规律的物业管理模式,不仅无法使我国的物业管理走上可持续发展的道路,还会由于物业管理体制、机制、模式和制度的落后,引发大量的社会问题。基于此,在梳理我国物业管理30年实践的基础上,分析了我国现行物业管理模式存在的主要问题,提出了再造我国物业管理新模式的框架。     

业主委员会的性质及其投票权研究

业主大会是社区的最高权力机构，业主委员会是代表全体业主对小区进行管理的一个群体自治组织。业主委员会应成为业主大会的常设机构，具有非营利性，对小区日常事务拥有决策权，对小区的物业管理具有监督权，但小区管理中出现的重大事项应提交业主大会决定。业主大会是由物业管理区域内所有业主组成的，但对建设单位业主、未入住业主以及大产权业主的选举权应当作出一定的限制。

遗传算法在装配线平衡中的应用

装配线平衡是混合装配生产线调度的重要基础,是面向订单装配(ATO)得以实施的技术瓶颈,对提高生产率和设备利用率也具有重要意义。在工位数量给定的条件下,文章针对装配线平衡的数学模型,提出了一种面向装配线平衡的非标准遗传算法。该算法基于各操作之间的逻辑优先关系产生可行操作序列而生成初始种群,保证解的可行性;在此基础上实现寻找最小节拍、选定较优序列进行遗传,并采用最优保存策略确保算法收敛到最优或近优解。最后通过实例验证了该算法的有效性和可行性。     

Site Selection Using Hybrid Analytical Hierarchy Processing: Evidence from Taiwanese Electronics Assembly Firms in China

An upswing in labor costs and currency appreciation during the 1980s caused Asian countries and economic entities such as Hong Kong, Japan, and Taiwan to search for new manufacturing sites to obtain lower manufacturing costs. China, with its huge, rapidly growing market, was one of the main options for these Asian economic dynamos. How to find an appropriate method to evaluate an optimum place for a factory setup in China is essential to an enterprise. Analytical hierarchy processing (AHP) is a method to solve complex multicriteria decision problems. However, to make decisions based only on AHP results is not sufficiently reliable, especially when the results are too close to be precisely determined. To strengthen AHP analysis, we propose a “hybrid AHP” method. This method computes an error band (EB) of final AHP scores using its 95% Confidence Interval to estimate AHP score error and calculates EB combined with a “bootstrap” to mitigate expert pectoral bias. Based on our methods, our decision rule is “maximized AHP score and minimized EB.” To verify our methods, we took Taiwanese electronic assembly manufacturers selecting manufacturing sites in China as a case study. Our research found that Eastern China has a relatively higher consensus of preference for establishing their manufacturing sites.
