“…However, a large number of invalid sequences would be generated in the solution process, which would affect the solution efficiency. Cai [25] used the stratified graph to express the parts assembly relationship and proposed a phased iteration strategy based on the ant colony algorithm to solve pDSP problems, however, it is assumed that the basic disassembly time of all components is equal. Zhang [7] proposed a pDSP approach based on fuzzy-rough sets, but this method may produce a sequence that does not meet the disassembly constraint.…”

To solve the problem of low disassembly efficiency of complex products, an asynchronous parallel disassembly sequence planning method of multi-manipulator based on improved shuffled frog leaping algorithm was proposed. Depending on the characteristics of this method, the disassembly manipulators are taken as the research object, and the minimum completion time of disassembly is taken as the optimization objective. Based on the basic disassembly time of parts, the disassembly preparation time caused by the change of disassembly tools and directions is considered, so that the objective function evaluation model is more realistic. Then, the mathematical model of asynchronous parallel disassembly sequence planning is constructed and the disassembly information modeling method is optimized. We proposed a new method based on the fastener constraint matrix and the part constraint matrix to build the information model of product disassembly. Based on this model, the detachable conditions are derived and the feasible disassembly sequence is obtained. In order to improve the performance of the proposed algorithm, a double-link encoding method and an efficient decoding operator is proposed. The adjustment orders which based on adjustment position and the substitution formulas are constructed to carry out the new segmental local evolution of frog individuals, and the update formula of frog position is reconstructed. Furthermore, the two-point mutation operator is added to the global information exchange strategy to enhance the search ability of the algorithm. The proposed algorithm is applied to a screw lifting mechanism and four products of varying complexity, and the results are compared with two algorithms. The results show that the proposed method can solve disassembly problems of different scales and is especially effective in solving large-scale disassembly problems.

“…The potential benefits of adaptive reuse rely on the fact that it is possible to take away components from an obsolete building and then repair, reuse, remanufacture, or recycle them. In this matter, some of the most important green design methods include design for disassembly, design for maintainability and serviceability, design for reuse, design for remanufacturing, and design for recyclability [27]. For existing assets, complete designing for disassembly is not possible, and the process is reduced to planning for disassembly.…”

“…If the disassembly planning is too complex or time-consuming, the associated economic and environmental costs could be higher than new construction. This field has been studied in the manufacturing industry since the last decade, concluding that disassembly planning can reduce the time and cost associated with disassembling products [27].…”

Adaptive reuse of buildings is considered a superior alternative for new construction in terms of sustainability and a disruptive practice in the current capital project delivery model for the renewal of today’s built environment. In comparison to green-field construction projects, adaptive reuse projects require distinct stages, definition of interfaces, decision gates, and planning methods in order to secure the success of the building project. Unfortunately, little research has been done regarding establishing feasible systems for the planning, assessment, and management of adaptive reuse projects, leading to underperforming building projects outcomes. Interface management (IM) can improve renovation projects outcomes by defining appropriate ways to identify, record, monitor, and track project interfaces. IM has the potential of bringing cost and time benefits during adaptive reuse projects execution. The aim of this study is to develop a reference framework for implementing IM for adaptive reuse projects. First, the inefficiencies of redevelopment projects are explained inside of a circular economy (CE) context. Second, an ontology of IM for adaptive reuse projects is defined based on the current barriers to adaptive reuse and the most common interface problems in construction projects. Third, the defined ontology is expanded through a case study by showing examples of adaptive reuse barriers on a case project, and how IM could have been part of the solution for these problems. Finally, this study concludes with the suggestions on interface management systems (IMS) implementation for future adaptive reuse projects.

The concept of circular economy have gained a popularity in the scientific areas for the past decades due to raising influence of climate change, overpopulation, deforestation, resource depletion, urbanization, pollution and other global issues. Real estate is crucial aspect for every human being, because majority of people spend majority of their lifetime in buildings which are mainly located in cities. Purpose of the study is to reflect how built environment and real estate industry can benefit from the features of circular economy concept while promoting the practices of sustainable development. Authors have carried out a study based on the methodology of literature review and state of the art review to show how features of circular economy can support practices of sustainable construction. Results show that the construction processes can be supported by features of circular economy throughout the whole life cycle of construction project including logistics, supply chains, design, manufacturing process, exploitation and maintenance of real estate and reusing the building materials. Research indicates that urban circular economy contributes to the development of sustainable societies. Additionally, efficient implementation of circular construction requires profitability for majority of stakeholders.
