“…In subject matter 3, the second criterion of optimisation, namely the cost minimisation, is introduced into TCM [12]. Methodology for calculating the correlation between cost and duration in the TOC/TCM method while planning and completing construction projects is proposed.…”

“…In theory, the size of the time buffers constitute 25% of an allotted critical path. In papers [12,16], the influence of choosing a critical path and also the influence of the system of project and feeding buffers on the overall duration of the project was analysed. The performed analysis and calculations indicate that shortening the duration of particular processes by 25% does not result in shortening the overall duration of the whole project by the same value.…”

“…Thus, the original single objective optimization problem (ie, optimal time or cost) is shifted to a bi-objective optimization problem (ie, optimal time-cost). The construction time-cost optimization problem has been examined extensively in the construction engineering and management literature (eg, Siemens, 1971;Tamimi and Diekmann, 1988;Que, 2002;Rogalska et al, 2008;Wu et al, 2009;Yu et al, 2010;Wongwai and Malaikrisanachalee, 2011).…”

Optimizing construction project scheduling has received a considerable amount of attention over the past 20 years. As a result, a plethora of methods and algorithms have been developed to address specific scenarios or problems. A review of the methods and algorithms that have been developed to examine the area of construction schedule optimization (CSO) is undertaken. The developed algorithms for solving the CSO problem can be classified into three methods: mathematical, heuristic and metaheuristic. The application of these methods to various scheduling problems is discussed and implications for future research are identified.

“…For example, well-known task sequencing rules such as SPT (shortest processing time) and LPT (longest processing time) [5]. The models from the collection of artificial intelligence methods can also be used here [2,6]. The initial schedule discussed has been developed using the specialized KASS software allowing for analysis of all possible workspace sequencing [3].…”

The paper presents a newly developed model aimed at minimizing the downtime in working brigades work. The developed method is dedicated to the construction planned using the stream method of work organization. The model focuses on the assumption of multi-tasking of working brigades. It has been possible to model the performance depending on the type of brigade and the type of work being performed. The article also shows an example illustrating the results of the model' s operation.Keywords: flowshop models, slack minimization, construction schedules Streszczenie W artykule zaprezentowano nowo opracowany model mający na celu minimalizację przestojów w pracach brygad roboczych. Opracowana metoda dedykowana jest dla budów planowanych z zastosowaniem potokowej metody organizacji robót. W modelu skupiono się na założeniu wielozadaniowości brygad roboczych. Przyjęto możliwość modelowania wydajności w zależności od typu brygady i rodzaju wykonywanego zadania. W artykule pokazano ponadto przykład ilustrujący wyniki działania modelu.Słowa kluczowe: modele potokowe, minimalizacja przestoi, harmonogramy budowlane
