“…Functional construction design and maintainability design have equal importance to the life span and cost of a system or a component (Guo et al , 2018). Construction of facilities, systems and components should (be made to) support their future maintenance throughout their life cycle (de Brito and Silva, 2020).…”

Purpose The maintainability of urban spaces has become critical with rapid urbanization to create an effective and safe environment for the increasing population. The absence of scientific studies exploring the factors that affect urban space maintainability (USM) has hindered the incorporation of maintainability aspects during the urban space planning and designing stages. This paper aims to establish critical factors for USM. Design/methodology/approach Qualitative content analysis is performed under an abductive approach to developing USM factors. A bibliometric search is conducted using databases including Scopus Elsevier, Emerald Insight, Science Direct, IEEE XPLORE and the American Society of Civil Engineers. The selected primary data set comprises journal papers on USM published after 2000. Seventy-three journal articles are selected through a comprehensive screening procedure and subjected to further analysis. The literature findings are processed via a software-assisted systematic coding and visualizing of the key data using NVivo 12 software. The coded USM factors are validated based on experts’ consensus statements by conducting an expert focus group discussion. Findings Twelve critical factors are established for USM; they include six design stage-related factors, one construction stage-related factor and five operational stage-related factors. Research limitations/implications Established USM factors give an insight into the main focus areas when incorporating maintainability into urban spaces. Originality/value The authors establish a set of maintainability factors for urban spaces based on the life cycle stages. USM factors such as vegetation management, interdepartmental coordination and work zone safety draw attention to context-specific aspects of USM.

“…Guo C.H. et al [19] proposed a design approach considering the relationship between maintainability and functional construction. A practical case was given by implementing the proposed approach for the lubrication system of an armored vehicle to validate the effectiveness and feasibility of the approach.…”

“…The second is the process based method [4][5][6][7], the maintenance process is modeled to support task demonstration in these methods. The last is the multiple attribute decision based method [8][9][10][11][12][13][14][15][16][17][18][19], different kinds of attributes are considered and maintainability deficiencies can be discovered with these methods.…”

Maintainability is a critical design characteristic of products. Maintainability evaluation plays an important role in maintainability design. Existing maintainability evaluation approaches neglect logistic effects on system maintainability. In this paper, tuples of stochastic colored petri nets (SCPN) are used to express the constituents of a maintenance process; and the maintenance process model is developed based on the SCPN. Approaches for calculating the required maintenance resources are proposed according to the state equation of the SCPN, and a method for calculating maintenance time is proposed by using an SCPN based discrete-event simulation. Finally, the line maintenance of a wheel steering system is used as a case study to illustrate the application and effectiveness of our proposed approaches. The work discussed herein provides a maintainability evaluation methodology based on the maintenance task demonstration that is conducted on the digital mockup of products. The approaches can be applied in the design stage when there are no physical mockups, and the maintainability design can be carried on concurrently with the development of products.
