Xiao-qiu Shi,Yan-yan Li,Wei Long

《工程管理前沿（英文）》 2016年第3卷第2期页码 132-135 doi: 10.15302/J-FEM-2016026

摘要： Logistics resource planning is an integration model of materials requirement planning and distribution resource planning which is a resource allocation technology. It is a technology of satisfying both production material supply and resource allocation optimization which is based on inventory management. For the remanufacturing supply chain, recycling and rebuilding of products form a reverse materials movement loop which challenges the traditional logistics resource planning system. For the characteristics of reverse logistics of remanufacturing supply chain, we propose a closed-loop supply chain resource allocation model based on autonomous multi-entity. We focus on integration resource allocation model of materials requirement planning and distribution resource planning considering remanufacturing.

Benefit-based cost allocation for residentially distributed photovoltaic systems in China: A cooperative

Xi LUO, Xiaojun LIU, Yanfeng LIU, Jiaping LIU, Yaxing WANG

《工程管理前沿（英文）》 2021年第8卷第2期页码 271-283 doi: 10.1007/s42524-019-0083-7

摘要： Distributed photovoltaic (PV) systems have constantly been the key to achieve a low-carbon economy in China. However, the development of Chinese distributed PV systems has failed to meet expectations because of their irrational profit and cost allocations. In this study, the methodology for calculating the levelized cost of energy (LCOE) for PV is thoroughly discussed to address this issue. A mixed-integer linear programming model is built to determine the optimal system operation strategy with a benefit analysis. An externality-corrected mathematical model based on Shapley value is established to allocate the cost of distributed PV systems in 15 Chinese cities between the government, utility grid and residents. Results show that (i) an inverse relationship exists between the LCOEs and solar radiation levels; (ii) the government and residents gain extra benefits from the utility grid through net metering policies, and the utility grid should be the highly subsidized participant; (iii) the percentage of cost assigned to the utility grid and government should increase with the expansion of battery bank to weaken the impact of demand response on increasing theoretical subsidies; and (iv) apart from the LCOE, the local residential electricity prices remarkably impact the subsidy calculation results.

A holistic approach for evaluating ecological water allocation in the Yellow River Basin of China

YANG Zhifeng, CUI Baoshan, CHEN He

《环境科学与工程前沿（英文）》 2007年第1卷第1期页码 99-106 doi: 10.1007/s11783-007-0019-z

摘要： The characteristics and sustainable management of water resources on a basin scale require that they should be managed using a holistic approach. In this study, a holistic methodology called the holistic approach in a basin scale (HABS) is proposed to determine the ecological water requirements of a whole basin. There are three principles in HABS. First, ecological water requirements in a basin scale indicate not only the coupling of hydrological and ecological systems, but also the exchange of matter and energy between each ecological type through all kinds of physical geography processes. Second, ecological water requirements can be divided into different types according to their functions, and water requirements of different types are compatible. Third, ecological water requirements are related to a multiple system including water quality, water quantity, and time and space, which interact with each other. The holistic approach in a basin scale was then used in the Yellow River Basin and it suggested that 265.0 × 10 m of water, 45% of the total surface water resources, should be allocated to ecological systems, such as rivers, lakes, wetlands and cities, to sustain its function and health. The ecological water requirements of inside river systems and outside river systems were respectively 261.0 × 10 and 3.65 × 10 m.

Multi-objective optimal allocation strategy for the energy internet in Huangpu District, Guangzhou, China

Pei LI, Guotian CAI, Yuntao ZHANG, Shangjun KE, Peng WANG, Liping GAO

《能源前沿（英文）》 2020年第14卷第2期页码 241-253 doi: 10.1007/s11708-020-0660-9

摘要： To improve the overall efficiency of the energy system, the basic structure for the energy internet of coordination and optimization of “generation-grid-load-storage” of Huangpu District, Guangzhou, China is designed, while the arrangement for the output of centralized and distributed energy module and energy storage are proposed. Taking economic benefit maximization, environmental benefit maximization and energy efficiency maximization as sub-objectives, the mathematical model of multi-objective optimal allocation and operation strategy of the energy internet is established considering supply-demand balance constraints, equipment characteristic constraints, operation mode constraints, and energy conditions constraints. The calculation results show that without considering the outsourced electricity, the balanced strategy, the economic development strategy, the environmental protection strategy, and the energy efficiency strategy are obtained by calculation, which are all superior to the traditional energy supply strategy. Moreover, considering the outsourced electricity, the proportion of outsourced electricity to total electricity is 19.8%, which is the system optimization of the energy internet under certain power demand. Compared with other strategies without outsourced electricity, the outsourced electricity strategy can have a certain emission reduction effect, but at the same time reduce the economic benefit. Furthermore, the huge difference in demand for thermal and cooling load between industrial and commercial areas results in the installed capacity of gas distributed energy stations in industrial areas being nearly twice as large as that in commercial areas. The distributed photovoltaic power generation is allocated according to the proportion of the installed roof areas of photovoltaic power generation system in residential, industrial, and commercial areas.

Optimal risk allocation in alliance infrastructure projects: A social preference perspective

Xiang DING, Qian LI

《工程管理前沿（英文）》 2022年第9卷第2期页码 326-336 doi: 10.1007/s42524-020-0145-x

摘要： The mechanism of risk allocation is designed to protect all stakeholders, and it is vital to project success. Qualitative and quantitative ways of optimizing risk allocation have been well documented in extant literature (e.g., allocation principles, models, and solutions), and the foci of existing research are usually the maximization of rational utility. Few research has focused on partners’ social preferences affecting the output of risk allocation. This study presents a quantitative approach based on modeling alliance member (AM)’s inequity aversion (IA) to analyze risk-sharing arrangements in an alliance project. Fehr and Schmidt’s inequity-aversion model is integrated into modeling partner’s utility. This paper derives results for an alliance leader (AL)’s optimal risk-sharing ratio and AM’s optimal risk-management effort simultaneously. The derivation is based on solving a restrained optimization problem using the conception and methods from Stackelberg game theory. Results show that an AM’s IA significantly affects risk allocation between AL and AM. Specifically, envious preference is positively related to AL’s optimal risk-sharing ratio, whereas guilty preference negatively affects AL’s optimal risk-sharing ratio. These findings will be of interest to academics and practitioners involved in designing alliance negotiations.

《信息与电子工程前沿（英文）》 2018年第19卷第3期页码 446-458 doi: 10.1631/FITEE.1601802

摘要：放射检查流程（radiological examination process，REP）执行中，为提高患者吞吐量和放射资源利用率，以及应对因临床需要而改变资源调度和分配决策时发生的突发事件，高效的资源调度和分配是关键。本文提出一种基于禁忌搜索的方法，用以解决REP执行中资源调度和分配问题。该方法主要目标是将平均检查流时间、资源平均空闲时间和延迟的加权总和最小化，同时还考虑突发事件的情形，即紧急或缺失的检查。对于特定参数组合，在考虑路由和资源约束等限制条件下，该方法能找到放射资源调度和分配的最优解。对应用案例进行了仿真，结果表明该方法能有效利用放射资源，提高REP执行中患者吞吐量。

Real option-based optimization for financial incentive allocation in infrastructure projects under public–private

Shuai LI, Da HU, Jiannan CAI, Hubo CAI

《工程管理前沿（英文）》 2020年第7卷第3期页码 413-425 doi: 10.1007/s42524-019-0045-0

摘要： Financial incentives that stimulate energy investments under public–private partnerships are considered scarce public resources, which require deliberate allocation to the most economically justified projects to maximize the social benefits. This study aims to solve the financial incentive allocation problem through a real option-based nonlinear integer programming approach. Real option theory is leveraged to determine the optimal timing and the corresponding option value of providing financial incentives. The ambiguity in the evolution of social benefits, the decision-maker’s attitude toward ambiguity, and the uncertainty in social benefits and incentive costs are all considered. Incentives are offered to the project portfolio that generates the maximum total option value. The project portfolio selection is formulated as a stochastic knapsack problem with random option values in the objective function and random incentive costs in the probabilistic budget constraint. The linear probabilistic budget constraint is subsequently transformed into a nonlinear deterministic one. Finally, the integer non-linear programming problem is solved, and the optimality gap is computed to assess the quality of the optimal solution. A case study is presented to illustrate how the limited financial incentives can be optimally allocated under uncertainty and ambiguity, which demonstrates the efficacy of the proposed method.

《工程（英文）》 2021年第7卷第7期页码 924-935 doi: 10.1016/j.eng.2021.03.014

摘要：

鉴于缺乏安全有效的新冠病毒肺炎（COVID-19）疫苗，一个主要的政策问题是如何在不同的社会人口学特征群体中分配疫苗。本文评估了迄今为止提出的COVID-19疫苗优先策略，重点关注其既定目标；所选分配方案对于大流行病进程和负担的影响机制；以及制定优先策略时出现的流行病学、经济、后勤和政治等主要问题。本文将一个简洁、按年龄分层的易感-暴露-感染-恢复模型应用于美国，以定量评估替代优先策略在保护死亡、保护感染和延长寿命方面的表现。我们证明了优先考虑重点岗位人群是减少病例数量和降低死亡损失生命年的可行策略，而在大多数情况下，通过优先考虑老年人来实现死亡人数的最大减少，即使疫苗能有效阻止病毒传播。这一特性的不确定性和疫苗针剂支付的潜在延迟加强了优先考虑老年人的呼吁。此外，我们还调查了支持分配策略的公平动机的强度，该策略将绝对优先考虑给予重点岗位人群能降低感染致死风险的疫苗。

《工程（英文）》 2017年第3卷第2期页码 257-265 doi: 10.1016/J.ENG.2017.02.014

摘要：

对于处在碳配额市场条件下以乙醇胺(MEA) 进行碳捕集的燃煤电厂，本文应用了基于强化学习的Sarsa 时间差分算法为其自行搜寻一种统一的竞标和运行策略。电厂的决策者的目的被定义为最大化电厂寿命下的贴现累计利润。其中，我们引入以下两个限制条件：一是碳捕集的高能耗和电力生产之间的权衡；二是碳排放交易市场中竞得的碳配额数量与电力生产导致的实际碳排放量的近似相等。本文给出了三个案例方便研究。第一个案例中，我们展示了Sarsa 算法将收敛到一个确定且优化的竞标和运行策略。第二个案例中，相互独立设计的运行和竞标策略与统一设计的运行和竞标策略相互比较，以表明加入了随时间变化、市场导向的碳捕集水平后，Sarsa 算法将有助于电厂决策者获得更高的贴现累计利润。第三个案例则引入了处在同一碳配额市场的另一电厂作为原电厂的竞争对手。两家电厂设置了相同的发电和二氧化碳捕集设备，但新电厂采用不同的策略获得利润。比较两家电厂的贴现累计利润，结果表明：采用Sarsa 学习算法、找到统一的竞标和运行策略的原电厂会更具竞争力。
