Abstract
Purpose
POSPD, as supplementation of public open spaces (POS), has become a common policy to moderate the intensification of urbanization. However, some access restrictions, both physical and information-wise, were deliberately designed by private developers to reserve the POSPD for their own gains, which further hampers POSPD’s publicness and leads to their failure to bear social responsibilities.
Design/methodology/approach
By analyzing the current situation of the availability of public open space in private developments (POSPD) from the perspective of information justice, this research aims at proposing a policy framework for an “accessible and interactive platform” which advocates promoting informational justice by integrating public participation into the establishment of an interaction loop to promote the revitalization of POSPD. The methodology includes the review of previous solutions and platforms, the establishment of a POSPD database and geographic information system (GIS) analysis.
Findings
The POSPD in Hong Kong are unevenly distributed physically while the information about them is injustice and inadequate. Understanding the existing informational injustice associated with POSPD and revitalizing the stock spaces is timely and vital. Using the user-generated data from volunteers as the information flow, the proposed responsive POSPD platform will provide continuous positive feedback for policy improvement to help realize the collaborative management and sustainable development of the POS.
Originality/value
Making use of information and communication technology (ICT) to extend the “public” to the “internet-based”, the proposed framework regards the exploitation of ICT to enhance information justice as a novel way to revitalize POSPD. It involves collaborative operation among citizen participation and official POS management.

Abstract
Purpose
The purpose of this study is to explore a new assembly process planning and execution mode to realize rapid response, reduce the labor intensity of assembly workers and improve the assembly efficiency and quality.
Design/methodology/approach
Based on the related concepts of digital twin, this paper studies the product assembly planning in digital space, the process execution in physical space and the interaction between digital space and physical space. The assembly process planning is simulated and verified in the digital space to generate three-dimensional visual assembly process specification documents, the implementation of the assembly process specification documents in the physical space is monitored and feed back to revise the assembly process and improve the assembly quality.
Findings
Digital twin technology enhances the quality and efficiency of assembly process planning and execution system.
Originality/value
It provides a new perspective for assembly process planning and execution, the architecture, connections and data acquisition approaches of the digital twin-driven framework are proposed in this paper, which is of important theoretical values. What is more, a smart assembly workbench is developed, the specific image classification algorithms are presented in detail too, which is of some industrial application values.
