Abstract
An important characteristic of many engineering systems which cannot be modeled by fault trees to perform system reliability analysis is that they behave dynamically. In this paper, the method of applying Petri Nets (Pns) as a modeling tool to represent the coherent fault trees is discussed. When the repair facility is added into the nets, the dynamic behavior of the repairable system can be studied through the nets by using equivalent Markov chains.

Abstract
Purpose
Anti-epidemic Emergency Projects (AEEPs) have unique characteristics such as a short construction period, high-quality requirements, complex construction environment, many construction participants and many uncertain affecting factors. The purpose of this paper was to propose the establishment method for the Construction Community (CC) of AEEPs (CC-AEEPs) by analyzing the management features of AEEPs, to establish the method of the Social Network Analysis (SNA) for CC-AEEPs, and to apply this method and the framework to Wuhan Huoshenshan Hospital for their verification.
Design/methodology/approach
According to the CC theory, this paper explored the member composition and the establishment method for CC-AEEPs. The optimal management factors of CC-AEEPs were proposed by combining the management features of AEEPs and the SNA method for CC-AEEPs was further established. Finally, the applicability of the method was verified through a case study, and some countermeasures for the CC-AEEP social networks were proposed.
Findings
The establishment of CC-AEEPs is an important guarantee to complete AEEPs with top speed and high quality. Ten types of CC-AEEP members all played different but irreplaceable roles in cooperative construction, among which the Government, the Contractor, and the Supervisor had outstanding performances. The SNA method could effectively analyze the complexity and cooperative relationship among the members in four aspects. The case study of Huoshenshan Hospital validated the important role of CC-AEEP and its social network in the AEEP research providing beneficial enlightenment for the cooperative optimization path of the AEEP construction participants.
Originality/value
The new establishment method for CC-AEEPs was proposed from the perspective of “cooperation among human, society, and engineering” according to the theories of the engineering sociology and the CC. In this paper, the SNA method was applied to the research on the AEEP construction for the first time and the SNA method for CC-AEEPs was purposed. The optimal management factors of CC-AEEPs and the expansion path of the CC-AEEP social networks were proposed according to the whole-process tracking of AEEPs in Wuhan.

The literature review aims to facilitate a broader understanding of on-demand service platform operations management and proposes potential research directions for scholars.
Abstract
Purpose
The literature review aims to facilitate a broader understanding of on-demand service platform operations management and proposes potential research directions for scholars.
Design/methodology/approach
This study searches four databases for relevant literature on on-demand service platform operations management and selects 72 papers for this review. According to the research context, the literature can be divided into research on “a single platform” and research on “multiple platforms”. According to the research methods, the literature can be classified into “Mathematical Models”, “Empirical Studies”, “Multiple Methods” and “Literature Review”. Through comparative analysis, we identify research gaps and propose five future research agendas.
Findings
This paper proposes five research agendas for future research on on-demand service platform operations management. First, research can be done to combine classic research problems in the field of operations management with platform characteristics. Second, both the dynamic and steady-state issues of on-demand service platforms can be further explored. Third, research employing mathematical models and empirical analysis simultaneously can be more fruitful. Fourth, more research efforts on the various interactions among two or more platforms can be pursued. Last but not least, it is worthwhile to examine new models and paths that have emerged during the latest development of the platform economy.
Originality/value
Through categorizing the literature into two research contexts as well as classifying it according to four research methods, this article clearly shows the research progresses made so far in on-demand service platform operations management and provides future research directions.

Abstract
Purpose
To examine “universal service” as a policy objective in post‐WTO accession Chinese telecommunications and analyze the challenges of the Chinese telecommunications system in defining and promoting public service ethos in a country that is marked by staggering disparities.
Design/methodology/approach
A range of media, academic, industry, and policy discourses on “universal service” and a broader notion of “public service,” together with recent government efforts in promoting “universal service,” are examined and assessed to develop an analysis of the uneven nature of China's telecommunications development and reveal the dynamics of “universal service” policy formation, as well as the impetuses and impediments in developing any notion of public service telecommunications in China.
Findings
Public service issues in China need to be situated within a continuing process of uneven development which comprises dimensions other than residential telephone access. Although the ultimate policy goal appears to develop a nationally accessible telecommunications infrastructure as the basis of a unified national economy, this overall objective is beset by conflicts and contingent on the dynamics of elite and popular struggles over and beyond telecommunications development. Despite the spectacular expansion in telephone access, pragmatic concessions to dominant power groups, rather than a principled commitment to “universal service,” let alone efforts to define the social functions of telecommunications in more democratic ways, have shaped the development of China's telecommunications.
Originality/value
The development of China's telecommunications infrastructure offers lessons both as to the likelihood of successfully establishing an integrated national economy, and the role of public service in that context. However, the Chinese telecommunications policy field remains extremely fluid.

Abstract
Purpose
Based on literature review, the purpose of this paper is to design a comprehensive evaluation system for pharmaceutical industry from the financial perspective, and then analyses the development strategy of Chinese pharmaceutical industry according to the data of listed companies.
Design/methodology/approach
This paper analyses the development strategy of Chinese pharmaceutical industry through building the grey dominance evaluation model including absolute degree of grey incidence model and relative degree of grey incidence model.
Findings
Through the analysis of the grey dominance evaluation model, the authors find that four factors including total assets turnover, quick ratio, inventory turnover and current ratio can be grouped into first grade assessment indicator when evaluating the performance of Chinese pharmaceutical industry. These four indexes contain the concept of operational efficiency which shows that operation capability is the key to support the development of Chinese pharmaceutical industry, needing to be highly valued when organizations making business policy. When it comes to velocity of development, the contribution of R & D intensity is relatively small, which shows innovation ability of China’s pharmaceutical industry is still weak. Innovation is the lifeblood of enterprise development, needing to be improved to promote enterprise’s core competitiveness in the future development.
Originality/value
This paper selects Y1-Y7 as the performance evaluation system of pharmaceutical manufacturing enterprises, while X1-X15 as performance evaluation index system from the financial perspective, which indicated that the evaluation system is scientific and practical. The empirical result shows that the operation capability makes the largest contribution to the performance of China’s pharmaceutical industry, while R & D ability and the enterprise core competitive ability are weak.

Abstract
China's defense industry is analyzed by comparing the technical level of the military and civilian products manufactured by China's nuclear, space, aviation, shipbuilding, ordnance, and electronics industries with their advanced counterparts. Generally, China's defense industry is about 20 years behind the global leaders. Thus, it is inappropriate to declare China's emergence as the world’s second military power. However, if it continues on its current development trajectory, it will attain that status in the near future.

Abstract
Purpose
This study aims to apply legitimacy theory and self-identity theory to the online food delivery (OFD) app service and then to investigate the impact of green brand legitimacy and biospheric value orientation perceived by customers on eco-friendly behavior.
Design/methodology/approach
This study focuses on the mediating role of trust in green brands and its perceived benefits (including psychological and environmental benefits). This study involved an online survey of 445 customers who had experienced using OFD services in the past six months.
Findings
The platform's green brand legitimacy and consumer perceived biospheric value orientation positively impact trust in green brands. Trust in green products and services significantly affects customers' perceived benefits and has a positive impact on eco-friendly service using behavior. Mediating effect analysis indicated that brand legitimacy and biospheric value have a positive indirect influence on the psychological benefits of supporting green activities and utilitarian environmental benefits.
Research limitations/implications
The convenience sampling method is used, and its purely quantitative nature may limit the generalization of the research results.
Practical implications
The OFD platform should encourage online catering retailers to use more eco-friendly packages for packaging food and minimize the provision of disposable tableware. The platform manager can provide consumers with knowledge and information on lowering related environmental pollution sources when ordering food.
Originality/value
This study innovatively introduces brand legitimacy into the green consumption literature. This is an essential expansion of the content of brand legitimacy and a supplement for the research field of eco-friendly behavior.
