Scheduling Model of Construction Activity With Time Couplings

Abstract

The algorithm of construction work graphic schedule which takes into account the proper sequencing problem has been presented. The algorithm is described step by step, ie the construction work organisation methods with zero couplings between realisation means. The calculation process of "Limit Possible Minimum" (LPM) taking into account technical and organisation limits is also shown. The second part of the paper includes a practical example which presents the method and the optimisation algorithm for the work organisation method with zero couplings among realisation means.

Optimization of Work Schedules Executed using the Flow Shop Model, Assuming Multitasking Performed by Work Crews

“…The value of is constant and is set by the previous short algorithm, , 2. Set the value of , 3. If then and return to step 2 of the algorithm.…”

“…In order to perform the optimization, scheduling of tasks must be done to set the right order of crew movement between work sites, thus set the order of work units. This part of the optimization can be performed using time couplings [2,3] by using time-cost ordering criteria.…”

Construction duration predictive model based on factorial analysis and fuzzy logic

“…One of the methods used to set the construction duration is the PERT/CPM technique, but it requires that the duration of the activities be known in the initial phase of the project, when the uncertainty is very high (CHANAS;ZIELIÃ, 2001;HEJDUCKI, 2003;ROGALSKA;HEJDUCKI, 2007;CHEN;HSUEH, 2008;RODRÍGUEZ et al, 2014).…”

Internet decision-making system for estimation of innovative projects in building construction

“…В интернете и периодических научных журналах [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] можно найти немало информации об управлении строительством и строительном оборудовании. Базы данных включают в себя описания наилучших практических решений, расчетов, анализа, программного обеспечения, систем экспертной оценки и принятия решений, разработанных в области управления строительством и строительной техникой и отражающих ряд новых услуг.…”
