Abstract
The paper presents the problem of optimal management of the resources in multiunit construction project. During the creation of the models of this kind of the project the flow-shop system is rarely used. Flow-shop system now is widely applied in modelling of industrial processes, computer systems. In the model presented in the paper flow shop system with teams of working groups is used. It allows its users to shorten the time of realization of multiunit construction projects in a significant way, because works in the project can be realized by teams of working groups of any cardinality. This is new model of multiunit construction project which has not been examined in field of scheduling of construction project yet. The presented optimization model of multiunit construction project with teams of working groups performing one type of work is NP-hard optimization problem. During the scheduling of such projects there was an artificial intelligence tool used, i.e. metaheuristic tabu search algorithm. Tabu search algorithm can provide solutions of very good quality. The paper also presents a calculation example of the above mentioned problem. The obtained in calculation example result is fully satisfactory.
Highlights
In the field of construction practice it is not uncommon to encounter cases of realization of such projects, which involve the implementation of either a number of building structures or their separate parts
One of the most commonly used models in scheduling theory is permutation flow shop system (Gupta, Stafford 2006). This system can be applied in scheduling of repetitive construction projects when it is a possibility to take into account units processing order in creation an optimal project schedule
Below there will be presented a new model of multiunit construction project with use of the flow shop system, which allows its users to use any number of working groups to carry one type of work in project
Summary
In the field of construction practice it is not uncommon to encounter cases of realization of such projects, which involve the implementation of either a number of building structures or their separate parts (which constitute the project). One of the most commonly used models in scheduling theory is permutation flow shop system (Gupta, Stafford 2006) This system can be applied in scheduling of repetitive construction projects when it is a possibility to take into account units processing order in creation an optimal project schedule. Below there will be presented a new model of multiunit construction project with use of the flow shop system, which allows its users to use any number of working groups to carry one type of work in project. This process will enable a significant acceleration of the works in the project, while meeting the accepted constraints
