Model decyzyjny wyboru podwykonawców budowlanych przy uwzględnieniu ich ograniczonej dostępności w czasie
Języki publikacji
Abstrakty
Most construction projects involve subcontracting some work packages. A subcontractor is employed on the basis of their bid as well as according to their availability. A viable schedule must account for resource availability constraints. These resources (e.g. crews, subcontractors) engage in many projects, so they become at the disposal for a new project only in certain periods. One of the key tasks of a planner is thus synchronizing the work of resources between concurrent projects. The paper presents a mathematical model of the problem of selecting subcontractors or general contractor’s crews for a time-constrained project that accounts for the availability of contractors, as well as for the cost of subcontracting works. The proposed mixed integer-binary linear programming model enables the user to perform the time/cost trade-off analysis.
W artykule przedstawiono model matematyczny problemu wyboru podwykonawców lub brygad roboczych generalnego wykonawcy przy założeniu ograniczonej w czasie (poprzez okna czasowe) dostępności wykonawców robót budowlanych. Proponowany model matematyczny (mieszany, binarny model programowania liniowego) umożliwia przeprowadzenie analizy czasowo-kosztowej przedsięwzięcia budowlanego. Uwzględnienie na etapie planowania rzeczywistych terminów dostępności zasobów podwykonawców oraz ich ofert cenowych, które mają wpływ na koszt i czas trwania przedsięwzięcia, może dać wykonawcy przewagę konkurencyjną na rynku usług budowlanych. Dalsze badania autorów będą się koncentrowały na opracowaniu algorytmu opartego na metodzie podziału i ograniczeń dedykowanego do rozwiązywania prezentowanego problemu harmonogramowania przedsięwzięć budowlanych i oceny jego efektywności oraz złożoności obliczeniowej.
