The paper concerns the problem of roadworks scheduling executed in the flow-shop system. Works may be performed parallelly with the acceleration (overlaps) of construction project, i.e. the following work on the assembly line can begin before the completion of the predecessor work. Taking into account the acceleration enables accurate modeling of complex real construction processes. The above fact can greatly shorten the time of realization of construction process which has a direct impact on reducing costs. The considered issue belongs to the class of NP-hard problems. We introduce the new: mathematical model, specific properties as an acceleration tools, as well as two new optimization algorithms for the problem considered: construction and tabu search. The execution of algorithms was illustrated on the example of a case study concerning the construction of roads. They were also verified on the examples taken from the literature and on already completed construction processes. The obtained results are fully satisfactory. The assigned execution times are close to optimal. The presented methods allow its practitioners (both the planners and the managers) to include in the model the acceleration of the works and the design of a much more efficient construction scheduling. The presented new scheduling method leads to a more competitive environment for contraction companies.

This work deals with the application of artificial intelligence instruments in a building schedule. In this article there was presented an original optimization scatter search algorithm taking into consideration both technological and organizational restrictions. This algorithm was applied to the real analysis of the industrial building project realization.

Potential applications of the CCS/BM method in the scheduling of continuous LSM (Linear Scheduling Model) construction activities are considered. The effect of time buffers – feeding buffers (FB) and project buffers (PB) – on total project realisation time (TT) is examined. Feeding buffers are found to have no direct full influence on TT if construction activities continuity is assumed. The influence of FBs on TT for other conditions considered in this paper still needs to be examined.

This paper presents and describes basic properties of construction work organization methods which use time couplings. In addition, fundamental methods of construction work organization, which enable the scheduling and synchronization of construction works and take into account several constraints encountered in practice, are also discussed.

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.
