A fuzzy decision support system for sustainable construction project selection: an integrated FPP-FIS model
(Journal of civil engineering and management, 2020)Sustainability has become a key concern for project selection in construction industries. Determining the best sustainable project based on various sustainability attributes is a very complicated decision. Accordingly, ... -
A fuzzy optimization model for methane gas production from municipal solid waste
(Soft computing letters, 2021)The availability of non-renewable fossil fuels in Jordan continues to decrease, which increases reliance on energy sources, such as, methane gas produced from municipal solid waste (MSW). Furthermore, during the COVID-19 ... -
A new constitutive model for the time-dependent behavior of rocks with consideration of damage parameter
(Journal of civil engineering and management, 2022)Deformation and time-dependent behavior of rocks are closely related to the stability and safety of underground structures and mines. In this paper, a numerical-analytical model is presented to investigate time-dependent ... -
A new testing procedure to quantify unfavourable environmental effect on mechanical performance of composite reinforcement system
(Proceedings of the 14th fib International PhD Symposium in Civil Engineering, 5-7 September 2022, Rome, Italy, 2022)Current technology development ensures a variety of material types for reinforcing and strengthening concrete structures. However, the absence of a uniform testing methodology complicates quantification (and comparison) ... -
A scientometric analysis of construction bidding research activities
(Buildings: Special issue: Costs and cost analysis in construction project management, 2023)Bidding is the process in which a contractor submits a tender to the owner of a construction project to undertake its execution. This enables companies to properly employ required contractors. This paper investigates the ... -
A soft computing approach based on critical chain for project planning and control in real-world applications with interval data
(Applied Soft Computing, 2021)Resource-constrained project scheduling problem (RCPSP) has been one of the most important topics in project scheduling in recent decades. RCPSP, due to the strategic importance of the projects and internal and external ... -
A test road with unbound base and sub-base course from MSWI bottom ash mixtures
(Buildings: Sustainable and Green Construction Materials, 2023)A considerable amount of literature has been published on municipal solid waste incinerator (MSWI) bottom ash as a substitute for natural road materials. However, most studies are conducted in the laboratory, and as a ... -
Adding granite polishing waste as sand replacement to improve packing density, rheology, strength and impermeability of mortar
(Powder technology, 2020)Reducing waste disposal from stoneware industry and reducing use of sand in construction industry are both important for sustainable development. One strategy to tackle both problems is to utilize the waste from stoneware ... -
Adding granite polishing waste to reduce sand and cement contents and improve performance of mortar
(Journal of cleaner production, 2021)Sand and cement are indispensable ingredients of concrete but their production is causing sustainability problems. Two strategies have been adopted to reduce their consumption, namely, sand replacement with solid waste and ... -
