Abstract
Purpose
The functionality and reliability of an overhauled aero-engine is determined by all configuration changes in the overhaul process. Identifying, recording, auditing, tracking and tracing of configuration modifications are significant and meaningful. Considering the barriers to these goals, this paper aims to put forward an approach to configuration management in the aero-engine overhaul process.
Design/methodology/approach
The overhaul configuration management model is proposed to describe an aero-engine’s configuration evolution trajectory in the overhaul process. The controlling and auditing procedures are put forward to control and audit parts’ return-to-zero statuses and overproof statuses. And some searching algorithms are also designed to enable tracking and tracing of the configuration status along the time coordinate, or get a snapshot of an aero-engine’s configuration at a certain time. The above model, procedures and algorithms have been implemented and adopted to fulfill the configuration management requirements in the aero-engine overhaul process.
Findings
The approach is effective in identifying, recording, controlling, auditing, tracking and tracing configuration changes in the overhaul process.
Practical implications
The approach’s implementation and adoption present a practical example for aero-engines’ configuration management issue in the overhaul process.
Originality/value
The work proposes an original aero-engine configuration management solution for the overhaul process and enables a reliable and accurate configuration management mode.

Abstract
Purpose
The purpose of this paper is to solve the asynchrony problem between the logistics stream and the information stream in the complex product assembly executive process.
Design/methodology/approach
States of assembly and logistics are described by transitions, and implemented via logistics agents and assembly agents. Events in the assembly executive process are described by places, and mapped to radio frequency identification (RFID) tags' states. An agent‐based complex product assembly framework is proposed. Mobile agents are used to encapsulate task and data, and RFID tags' states are able to trigger dispatching of assembly agents and executing of assembly tasks. Assisted by mobile agents' retraction mechanism, on‐site data are carried back when assembly tasks are finished.
Findings
An assembly executive process Petri net and a mobile agent‐based complex product assembly framework are proposed.
Originality/value
Dynamic matching mechanism between assembly tasks and materials is achieved, and controlling and monitoring methods of complex product assembly executive process are enhanced.

Abstract
Purpose
Taking Huangshan City as an example, the purpose of this paper is to explore the relationship between gross products of agriculture (GPA), its main composition as well as their influential intermediate inputs, followed by some suggestion, in order to optimize agricultural industrial structure and distribute the ratio of various inputs in agriculture, farming, forestry, animal husbandry and fishery, so as to improve GPA of Huangshan City.
Design/methodology/approach
This paper is characterized by an exploratory research by using the grey incidence analysis based on the grey systems theory initiated by Chinese professor Julong Deng. The original data processed in the model are quoted from the Statistical Yearbook of Huangshan City.
Findings
This paper draws some important conclusions. First, in terms of large, intermediate inputs in animal husbandry production and fishery production are two important aspects which affect the growth potentiality of agricultural gross products in Huangshan City. This also reflects that the development potentialities of fishery and animal husbandry are larger. Second, the level of agricultural modernization is relatively low in Huangshan City, the growth of agricultural output relies on a large number of inputs such as fertilizers, pesticides, but it also reflects the agriculture production system has huge potentiality to increase in Huangshan City from the side. Third, agriculture producer services as a whole is still relatively weak in Huangshan City. It is difficult to adapt to the development of modern agriculture and agricultural modernization. Finally, the results show that intermediate inputs have different influence on farming, forestry, animal husbandry and fishery.
Originality/value
Suggestion are also proposed to the related policy makers as follows: to vigorously develop animal husbandry and fishery in order to optimize agricultural industrial structure of Huangshan City, to improve agricultural modernization level, to speed up the service support system construction of agriculture production, to optimize the allocation of inputs in farming, forestry, animal husbandry and fishery reasonably.

Abstract
Purpose
The purpose of this article is to provide an overview of cloud computing and its increasing impact on systems librarianship, and to propose strategies for systems librarians as they embrace the shift to cloud computing.
Design/methodology/approach
The approach takes various forms, including needs assessment, literature review, impact analysis, environmental scanning and strategic planning.
Findings
Cloud computing has a great impact on systems librarianship. There is not enough evidence to prove that such environmental changes will likely obviate the need for systems librarians in the near future. Systems librarians must upgrade their knowledge and skills to meet the new demands of the change.
Originality/value
At the time of this literature review, few publications were dedicated to the discussion of cloud computing and systems librarianship. This article is intended to fill the gap of the literature in this area.

Abstract
Purpose
To encourage natural and cultural heritage tourism, this study intends to offer a sustainable approach to resurfacing a historic canal in Old Dhaka, Bangladesh. Dholaikhal, the canal that was once a vital artery of Old Dhaka, has been encroached upon and buried beneath box culverts to accommodate the city’s road network development, resulting in environmental deterioration and the loss of cultural significance.
Design/methodology/approach
This study employs a mixed-method research approach that incorporates multidisciplinary techniques after exploring the canal’s historical trace and present condition thoroughly through historical and contextual study, map regression, land use pattern analysis, transect walks, photographic documentation and a design workshop.
Findings
Findings unfold the scope of reviving the forgotten existence of Dholaikhal, indicating actionable steps for intervention. The proposed regeneration of Dholaikhal and its adjacent surroundings confirms a symbiotic relationship between heritage preservation and tourism development by focusing on ecological restoration and cultural preservation through community engagement.
Practical implications
The study offers practical recommendations for implementing the suggested design solutions, focusing on fostering collaboration and offering invaluable perspectives for policymakers, urban designers and local residents. It also establishes a model for revitalizing urban waterways of historical significance, therefore promoting a balanced coexistence between the city’s natural and cultural heritage.
Originality/value
This research engages a mixed-method approach to preserving natural heritage, proposing a holistic model that simultaneously considers ecological awareness, historical relevance and community engagement.
