Värdeflödesanalys på Saab Training Systems i Huskvarna
Saab Training Systems (STS) in Huskvarna is manufacturing material for educationalpurposes to armies worldwide. They are now implementing parts of the Lean productionconcept in their organisation.One part of the work with Lean production is to eliminate waste. To be able to identify waste,value stream mapping is a good tool and also what we used in our thesis. To gain a betterefficiency in the production of Personnel Detector Device (PDD) flow was one of our goals.The PDD is a harness used during battle training which registers if the user is being hit by itsenemy.Our work with the thesis started up with a short education in Lean production and in valuestream mapping (VSM). The work proceeded with a VSM of the production flow of the PDD,interviews were made and studies of literature were done to gain greater knowledge of thesubject and solve the task.The VSM resulted in five areas which were followed up out of those six we identified. Theareas were as followed: to examine why the reliability in a test chamber were down at 83percent, look over batch size and setup time, find out whether two workstations that wereusing the same equipment should be separated or not and also look through the existing layoutand create a new.The results from this were that what took down the reliability in the test chamber was isolatedto a few things which were followed through and visualized in a Pareto diagram.Big batch sizes as a result of few start ups of the order which now will be changed in to moredaily start ups with the actual demand in mind. The setup time is a big part of the change inbatch size. Valuable process time is lost as the operators have to collect material which isbeing needed for the assembling of the products. STS is now going to follow up the processand se how to make for changes.The two stations sharing the same equipment is a kind of a problem in the material flow asproducts some times get stacked up here. To solve this problem the only solution is toseparate them into two different work stations. This will affect the layout in the factory andtherefore a layout for the future was created from the results which are presented above andtheory of how to create a layout.Our work at STS resulted in that the areas mentioned above were followed up and is nowbeing implemented in various scale.
