“…This mutual interdependency was analysed by many researchers, e.g. in terms of time and cost for water supply systems (Zujo et al, 2017) and the balance of cost, time and quality for reinforced concrete (Hosseini et al, 2017). The aspect of project cash flow is also crucial as it allows the assessment of working capital requirements (Maravas and Pantouvakis, 2012).…”

Contract management is a crucial component of any project. As construction projects are complex and difficult to manage, adequate attention must be given to the related contract management issues. Inexpert management can bring about serious unfavourable consequences that can even result in a project failure. This study aims to explore a specific case study: A private road construction project implemented in the Czech Republic. The analysis consists in identifying potential problems and discussion of their implications. The problem is investigated on three levels: economic, technical and legal. The paper also considers contrasting attitudes of the contracting parties (buyer and supplier), e.g., from the point of view of the causes of problems. Several recommendations are formulated on the basis of the research findings. The results of this study have an ambition to improve contract management capabilities in the construction sector in order to prevent the occurrence of similar problems in future and contribute to our understanding of long-term effects of contract management problems throughout the life cycle.

“…Additionally, they developed a shuffled frog-leaping algorithm (SFLA) to solve the problem [12]. Hosseini et al (2017) proposed a multi-objective TCQ trade-off mathematical programming model for an underground project and a sample project with 10 activities was solved by the NSGA-II algorithm. These multi-objective methods obtain the Pareto optimal frontiers with two significant challenges: The Pareto set may not be properly distributed and may be very large which raises the question of how to select a specific solution [13].…”

Application of Three Metaheuristic Algorithms to Time-Cost-Quality Trade-Off Project Scheduling Problem for Construction Projects Considering Time Value of Money

Time, cost, and quality have been known as the project iron triangles and substantial factors in construction projects. Several studies have been conducted on time-cost-quality trade-off problems so far, however, none of them has considered the time value of money. In this paper, a multi-objective mathematical programming model is developed for time-cost-quality trade-off scheduling problems in construction projects considering the time value of money, since the time value of money, which is decreased during a long period of time, is a very important matter. Three objective functions of time, cost, and quality are taken into consideration. The cost objective function includes holding cost and negative cash flows. In this model, the net present value (NPV) of negative cash flow is calculated considering the costs of non-renewable (consumable) and renewable resources in each time period of executing activities, which can be mentioned as the other contribution of this study. Then, three metaheuristic algorithms including multi-objective grey wolf optimizer (MOGWO), non-dominated sorting genetic algorithm (NSGA-II), and multi-objective particle swarm optimization (MOPSO) are applied, and their performance is evaluated using six metrics introduced in the literature. Finally, a bridge construction project is considered as a real case study. The findings show that considering the time value of money can prevent cost overrun in projects. Additionally, the results indicate that the MOGWO algorithm outperforms the NSGA-II and MOPSO algorithms.

“…Several authors have applied modeling techniques such as fuzzy logic (Amiri and Golozari, 2011; Cristobol, 2013); grey numbers (Razavi et al, 2015;Mahdiraji et al, 2016); and genetic algorithms (Hosseini et al, 2018) to address this problem when quality follows a linear scale. Salmasnia et al (2016) use a response surface methodology to find an optimal amount of resources to assign to activities so that project total time and cost are minimized while quality characteristics are maximized.…”

We consider how uncertainty affects tradeoffs between time, cost, and quality, modeling quality as a continuous function of time and cost. A translation agency example demonstrates that uncertainty can be modeled by making the quality function parameters stochastic. This leads to our Stochastic Time Cost Quality Tradeoff Problem (STCQTP), which determines optimal levels of time, cost, and quality to maximize expected quality. A software development example applies this model to show the considerable impact uncertainty can have on project quality. In addition, multiple probability distributions are considered, and the effect of correlation between time and cost is explored. The STCQTP model provides an approach to determine an optimal hedge against uncertainties that fully takes quality into consideration.
