Abstract [en]

The purpose of the work is to analyze and balance an assembly line at Fläkt Woods in Jönköping. The work is going to answer the questions about today’s throughput time, how much waste that occurs, number of staff at the assembly line, how the supply of material works and possible improvements that can be made at the work stations. The work is also going to give a proposal of improve-ments that can be made.

The methods used to get the result include observations and measurements, con-versations with technicians and operators and also data from Fläkt Woods’ data-base.

Large variations in throughput time are measured during the measure period, from 3 hours up to 5 hours and 35 minutes. These variations depend mainly on the time the air handling unit spends between the stations. The identification of the bottleneck was shown that it occurred in the last station in the assembly line. This results in a pressure from the stations behind with a long throughput time as a con-sequence. The largest source of waste is the operators’ waiting time. The measures that have been made show that the operators wait 33.4 % on average of the time available. The number of operators varies from ten to twelve during the measure period. This number of operators is too high in consideration of the high waiting times. It results in difficulties for the operators to move between the stations be-cause every station is fully manned. The supply of larger components for example fans, batteries, rotary heat exchangers and dampers for the air handling units are made by a truck driver. This leads to disorder in the work stations and fixed posi-tions for a number of smaller components and tools go missing.

The analysis of the result shows that the pressure that occurs in the assembly line results in high throughput time because the units wait a long time between the stations. To eliminate these waiting times, a suction must be created. The difficul-ties for the operators to move between the stations can be solved with a lower number of operators. This makes it easier for the operators to move between the stations and reduce the waiting time for the operators.
