Sustainable public-private partnerships: Balancing the multi-actor ecosystem and societal requirements

Pekka Leviäkangas, Yanbing YE, Oluwole Alfred OLATUNJI

《工程管理前沿（英文）》 2018年第5卷第3期页码 347-356 doi: 10.15302/J-FEM-2018020

摘要：

The funding gap of public infrastructure networks (roads, railways, ports, electricity, and energy lines) can be solved partly by introducing private capital for investments, i.e., public-private partnerships (PPP). This paper introduces an integrated model of a PPP project and investigates its implications on PPP policies and strategies regarding appropriate project appraisal and selection. The model has different resolution levels, namely, project level, business ecosystem level, and market and societal levels. The integrated model suggests that investing in merely financially viable projects is insufficient to realize economically and socially sustainable and acceptable projects.

Consistency Guarantees for Professional Appraisal of Geotechnical Engineering Design under Market Leading

Jian-ye Zheng

《工程管理前沿（英文）》 2015年第2卷第1期页码 82-85 doi: 10.15302/J-FEM-2015012

摘要： Peer review is central to the process of modern engineering. Open peer review gives the impression that decisions are arrived at in a fair and meritocratic manner with an objective, reliable, consistent process. It is responsible for identifying methodological flaws and for improving the quality. Assistance from somebody in the same discipline is valuable. Clients refer to reviewers as referees since they help to determine the fate of a design. The client sets up a hanging committee to carry out open peer review to decide whether a piece of work should be accepted, revised or rejected. Reviewers in similar specialties make up a professional group. In an open peer review refereeing a retaining and protection structure design of building foundation pit excavation, an outside expert as an assessor, might master the art of review to pay attention to guarantee consistency of processes and outcomes.

Review on ranking and selection: A new perspective

L. Jeff HONG, Weiwei FAN, Jun LUO

《工程管理前沿（英文）》 2021年第8卷第3期页码 321-343 doi: 10.1007/s42524-021-0152-6

摘要： In this paper, we briefly review the development of ranking and selection (R&S) in the past 70 years, especially the theoretical achievements and practical applications in the past 20 years. Different from the frequentist and Bayesian classifications adopted by Kim and Nelson (2006b) and Chick (2006) in their review articles, we categorize existing R&S procedures into fixed-precision and fixed-budget procedures, as in Hunter and Nelson (2017). We show that these two categories of procedures essentially differ in the underlying methodological formulations, i.e., they are built on hypothesis testing and dynamic programming, respectively. In light of this variation, we review in detail some well-known procedures in the literature and show how they fit into these two formulations. In addition, we discuss the use of R&S procedures in solving various practical problems and propose what we think are the important research questions in the field.

Control mode selection for modal control of long-span arch bridge

Zhengying LI, Zhengliang LI,

《结构与土木工程前沿（英文）》 2009年第3卷第4期页码 401-406 doi: 10.1007/s11709-009-0052-z

摘要： For seismic control of arch bridge, a model reduction of long-span arch bridge was implemented based on modal analysis. As for the critical mode selection, an approach based on the maximum modal displacement was presented. This approach takes into consideration the effect of external seismic excitation and is more reasonable than only considering dynamic bridge characteristics based on a modal contribution ratio. The time domain and frequency domain analysis method were used to verify the simplified model of the Nimu arch bridge in Tibet as an example. The numerical results show that the method of maximal modal displacement better analyze long-span arch bridge when multisupport seismic excitation must be considered. The reduced-order system also is more in line with the performance of the original model.

Supplier selection and order splitting in multiple-sourcing inventory systems

WANG Guicong, JIANG Zhaoliang, LI Zhaoqian, LIU Wenping

《机械工程前沿（英文）》 2008年第3卷第1期页码 23-27 doi: 10.1007/s11465-008-0016-3

摘要： Supplier selection and inventory control are critical decision processes in single-item multiple-supplier systems. An integer linear programming model is proposed to help managers determine the reorder level, choose the best suppliers, and place the optimum order quantities so that the total average inventory cost is minimum, and constraints of supplier ability, quality, and demand are considered. An algorithm combining the branch-bound algorithm and enumeration algorithm is developed to solve the problems. Application of the proposed model in an automobile industry shows that it is effective.

Genomic regions under selection for important traits in domestic horse breeds

Xuexue LIU, Yuehui MA, Lin JIANG

《农业科学与工程前沿（英文）》 2017年第4卷第3期页码 289-294 doi: 10.15302/J-FASE-2017155

摘要： Horses were domesticated 5500 years ago, thousands of years later than other domestic animals; however, in this relatively short period, domestic horses have had a great impact on human history by accelerating civilization, revolutionizing warfare and advancing agricultural production. Modern breeding using marker-assisted selection has greatly accelerated breeding progress. Therefore, identification of genetic markers underlying the traits of interest in domestic horses is the basis for the modern breeding system. In this review, we present an overview of genetic mapping studies and genome wide analyses to identify the genomic regions targeted by positive selection for four important aspects of horses, coat color, racing performance, gait and height at withers. The locus, for example, has been shown to be the main gene responsible for chestnut color, and the locus has been shown to control the muscle fiber growth in racing breeds. The missense mutation in is the causal mutation for the alternate gaits in horses. Height at withers, a quantitative trait, was mapped to four major loci (3:105547002, 6:81481064, 9:75550059 and 11:232597 32) that can explain 83% of the height variations in domestic horses.

Case-based reasoning for selection of the best practices in low-carbon city development

Zhenhua HUANG, Hongqin FAN, Liyin SHEN

《工程管理前沿（英文）》 2019年第6卷第3期页码 416-432 doi: 10.1007/s42524-019-0036-1

摘要： Cities emit extensive carbon emissions, which are considered a major contributor to the severe issue of climate change. Various low-carbon development programs have been initiated at the city level worldwide to address this problem. These practices are invaluable in promoting the development of low-carbon cities. Therefore, an effective approach should be developed to help decision makers select the best practices from previous experience on the basis of the impact features of carbon emission and city context features. This study introduces a case-based reasoning methodology for a specific city to select the best practices as references for low-carbon city development. The proposed methodology consists of three main components, namely, case representation, case retrieval, and case adaption and retention. For city representation, this study selects city context features and the impact features of carbon emission to characterize and represent a city. The proposed methodology is demonstrated by applying it to the selection of the best practices for low-carbon development of Chengdu City in Sichuan Province, China.

Jingmei LI , Tieying LIU , Yuanyuan ZHANG , Lei LI ,

《环境科学与工程前沿（英文）》 2009年第3卷第3期页码 341-347 doi: 10.1007/s11783-009-0038-z

摘要： This paper serves to appraise the monetary cost of coastal recreational resources in Qingdao using the travel cost method (TCM), which is typically used in developed countries. The total revenue produced by Qingdao’s coastal recreational resources is about RMB 5.51×10 annually, based on questionnaires given at Qingdao’s major tourist destinations. These questionnaires establish correlation functions that factor in the number of tourists, travel expenses, etc. The data processing software named Eviews was used to determine the tourist demand regression curve and to calculate their residual and actual travel expenses. The results of this study can provide a scientific basis for applicable industries interested in development and management decision-making. Therefore, this study assesses the reasonable usage of coastal recreational resources.

Face recognition based on subset selection via metric learning on manifold

Hong SHAO,Shuang CHEN,Jie-yi ZHAO,Wen-cheng CUI,Tian-shu YU

《信息与电子工程前沿（英文）》 2015年第16卷第12期页码 1046-1058 doi: 10.1631/FITEE.1500085

摘要： With the development of face recognition using sparse representation based classification (SRC), many relevant methods have been proposed and investigated. However, when the dictionary is large and the representation is sparse, only a small proportion of the elements contributes to the 1-minimization. Under this observation, several approaches have been developed to carry out an efficient element selection procedure before SRC. In this paper, we employ a metric learning approach which helps find the active elements correctly by taking into account the interclass/intraclass relationship and manifold structure of face images. After the metric has been learned, a neighborhood graph is constructed in the projected space. A fast marching algorithm is used to rapidly select the subset from the graph, and SRC is implemented for classification. Experimental results show that our method achieves promising performance and significant efficiency enhancement.

Building of Post-project Management

Yu Han,Yu-fei Li,Hu Cheng

《工程管理前沿（英文）》 2014年第1卷第4期页码 353-357 doi: 10.15302/J-FEM-2014051

摘要： Traditional project management often ignores problems arising after project completion such as value changing, functional decline, waste of resources and environmental pollution during the operation and dismantling process. This paper advances the concept of “post-project”, builds a framework for post-project management with case analysis, as the social development and new requirements for project management by environmental protection. Post-project refers to a project which no longer possesses normal value, because of loss after use, inability to adapt to new requirements, artificial destruction, damage beyond control, and deprivation of value after the completion of the project. Post-project management encompasses a series of management and technical activities including updating, reforming, removal, recovery, and recycling. The process of post-project management is composed of classification and characteristics of post-projects, management decisions, implementation, and evaluation. Post-project management can realize the sustainable development of project and society.
