“…Recently, incorporating stochastic demand and suppliers' imperfect quality, omy et al [12] proposed an integrated model for supplier selection with considering inventory management and inbound transportation. Chiu et al [13] explored the combined effects of overtime, stochastic breakdowns, and rework on the inventory replenishment decision. Johari et al [14] analyzed coordinated joint pricing and periodic review ordering choices for a supply chain with stochastic pricedependent demand.…”

In this highly volatile, uncertain, complex, and ambiguous (VUCA) environment, a fuzzy inventory optimization problem is a hot topic that received the most attention from both academicians and practitioners. In this paper, the authors have studied the integrated inventory problems under trade credit in fuzzy environments, where the demand rate and deterioration rate are taken here as triangular fuzzy numbers. Accordingly, three types of fuzzy programming models as fuzzy expected cost minimization model, fuzzy α-cost minimization model, and credibility maximization model are built according to different management goals. Since the problem is shown to be NP-hard, this research focuses on proposing a hybrid intelligent algorithm by integrating fuzzy simulation, neural network, and genetic algorithm for solving these models. Then, some numerical examples are presented to illustrate the benefits of the models and evaluate the efficiency of the algorithms. The computational experiments show that the trade credit strategy has a positive impact on improving the supply chain’s performance and reducing its total cost. In addition, the maximum relative error of the objective values is less than 1%, which implies that the hybrid intelligent algorithm is robust to the parameter settings and effective in solving our models. Finally, the practical implications are discussed and useful managerial insights are given.

“…Despite an increasing amount of research into construction rework (e.g., Asadi et al, 2021;Garg & Misra, 2021), the association between its reduction and safety improvement has become a significant knowledge gap, and improvements have been minimal. Most studies investigating measures to minimise and control rework in construction have the ultimate aim of improving labour productivity and time-cost performance (e.g., Chiu et al, 2021;Hwang & Yang, 2014), which aligns with Das' et al (2008) assertion that safety has been inexplicably overlooked in the operations management literature. Others investigate rework minimisation (e.g., Zhang et al, 2019) and safety management and improvements (e.g., Hallowell & Gambatese, 2009;Pereira et al, 2020) independently, although safety and rework management processes are somewhat comparable.…”

Previous studies demonstrate that rework can lead to more safety incidents. However, there is an inadequate understanding of how construction rework reduction measures may significantly decrease the likelihood of safety incidents in developing countries. To explore how construction organisations can integrate rework minimisation and safety management in practice, this study examines the effectiveness of the management strategies that can reduce rework and improve safety. Based on a two-stage detailed literature review of both rework- and safety-related studies, 13 managerial measures are recognised that are capable of jointly reducing rework and safety incidents for construction projects. A field survey involving construction professionals in Malaysia was used to analyse and rank these measures according to effectiveness indices for rework, safety and joint rework-safety management. Factor analysis yielded a two-factor solution comprising (1) project management best practices and (2) proactive competency management. It is suggested that the construction industry would benefit from simultaneously ameliorating the quality and safety performance of projects by adopting effective joint measures that are predominantly guided by process (best practices) and people (competency management) components.
