Abstract
Denne afhandling undersøger, hvordan tidsplanlægning på byggepladser kan gøres mere pålidelig ved at kombinere Last Planner System (LPS) og Location‑Based Management System (LBMS). LPS er en samarbejdsbaseret, kortsigtet planlægningsmetode, hvor hold forpligter sig til realistiske opgaver. LBMS organiserer og styrer arbejdet efter geografiske områder og arbejdsflow. Emnet er valgt, fordi traditionelle produktionsstyringssystemer ofte har svært ved at håndtere byggepladsers kompleksitet. Siden 1966 er produktiviteten i dansk byggeri kun steget med omkring 10 %, mens andre brancher er steget op mod 100 %, hvilket afspejler tids- og budgetoverskridelser og ineffektivitet. LPS og LBMS rapporteres hver for sig at forbedre planpålidelighed og styring, men der findes begrænset forskning og vejledning i at bruge dem sammen. Afhandlingen undersøger derfor, hvordan systemerne kan anvendes i kombination, og hvor praksis afviger fra teorien.
This thesis examines how to make on‑site construction schedules more reliable by combining the Last Planner System (LPS) and the Location‑Based Management System (LBMS). LPS is a collaborative, short‑term planning method in which teams commit to realistic tasks, while LBMS organizes and controls work by location and flow. The topic was chosen because traditional production control systems struggle with the complexity of construction sites. Since 1966, productivity in Danish construction has grown by only about 10%, while other industries have increased by up to 100%, reflecting time and cost overruns and inefficiencies. LPS and LBMS are each reported to improve schedule reliability and control, but there is limited research and guidance on using them together. The thesis therefore explores how to apply the two systems in combination and where practice diverges from theory.
