Elevators are used every day and that puts expectations on how fast an elevator can handle passenger requests. This report aims to describe different elevator assignment algorithms for Elevator Supervisory Group Control (ESGC) systems and compare them to each other, with an emphasis on the delay time. To research the field of ESGC systems four different algorithms were chosen and implemented: Simple control, Zone control, Collective control and Fuzzy control. The algorithms were also chosen in such a way that their strategies differentiated from each other to some degree. The algorithms were then tested under conditions similar to an office building with interfloor traffic. Five different test cases demonstrated the performance and behavior of the strategies in varying environments. While Collective control proved to have a consistent performance, the more calculated Fuzzy control had the best statistical results. Zone control was the most affected by challenging conditions such as high traffic in the building. Simple control divided the workload equally, but did not make suitable elevator assignments. ; Hissar används varje dag och det skapar förväntningar på hur snabbt en hiss kan hantera passagerarresor. Den här rapporten ämnar beskriva olika hisstilldelnings-algoritmer för Elevator Supervisory Group Control (ESGC) system och även jämföra dessa med varandra, med tyngdpunkt på fördröjningstiden. För att undersöka ämnesområdet ESGC system valdes och implementerades fyra olika algoritmer: Simple control, Zone control, Collective control and Fuzzy control. Algoritmerna valdes ut på ett sätt, så att deras strategier skilde sig åt till en viss grad. De testades sedan i en miljö som efterliknar ett kontorshus med trafik mellan våningar. Fem olika testfall demonstrerade prestationer och beteenden hos strategierna i varierande miljöer. Collective control hade bevisligen konsekvent prestation, medan den kalkulerande Fuzzy control åstadkom de bästa statistiska resultaten. Zone control påverkades i högst grad av ...
