Abstract [en]

The need to work with Design for Automatic Assembly (DFAA) has been widely recognizedin the literature. However, the implementation of DFAA is not clearly defined. Therefore, thepurpose of this master thesis is to investigate and contribute with knowledge of how DFAAshould be implemented into an organization, such as Company Y.Several interviews have been conducted to establish a current state analysis, to receive anunderstanding of the current problems at Company Y and how to address them. Abenchmarking study was conducted, where the three companies Ericsson, Company X andScania were interviewed. All three companies have successfully implemented DFA and wereinterviewed with the purpose to obtaining their best practices. The study also included an earlyimplementation of DFAA, where a software based DFA2-method created by Eskilander (2001)was tested on a current product and a new developed design concept at Company Y. Based onthis a recommended workflow of the evaluation could be attained.Based on the empirical gatherings several recommendations of how DFAA should beimplemented into the organization could be made. The study highlights that DFAA should beapplied as early as possible in the product development process. The DFA2-method should beutilized at product level to facilitate concept selection and at part level to make theproducts/modules suited for automatic assembly, before the design is “locked” and before aphysical prototype is created. The departments that should be working with DFAA includesindividuals from production, design quality and purchasing. However, once DFA becomesrooted in the company, more functions in the company’s supply chain will become affected.This means that more functions might need to be included in the work of DFAA. Finally, thestudy includes a decision model, in which the decisions are based on the measurable valuesreceived from the DFA2-method.

Abstract [sv]

Behovet av att arbeta med Design for Automatic Assembly (DFAA) har uppmärksammat ilitteraturen. Däremot har implementeringen av DFAA inte blivit tydligt definierat. Syftet meddetta examensarbete blir således att undersöka och bidra med kunskap om hur DFAA skaimplementeras i en organisation, så som Företag Y.Flera intervjuer har genomförts för att upprätta en nuvarandeanalys för att få förståelse för derådande problemen hos Company Y och hur dessa ska hanteras. En benchmarkingstudiegenomfördes, där de tre företagen Ericsson, Company X och Scania intervjuades. Alla treföretagen har framgångsrikt implementerat DFA och har intervjuats med syftet att erhålla derasbästa praxis. Studien innefattar även en tidig implementering av DFAA, där enmjukvarubaserad DFA2-metod skapad av Eskilander (2001), har testats på en aktuell produktoch ett nytt utvecklat koncept på Company Y. Baserat på detta kunde ett rekommenderatarbetsflöde av utvärderingen presenteras.Baserat på empiriska studien kunde flera rekommendationer gällande hur DFAA skaimplementeras i en organisation skapas. Studien belyser att DFAA bör tillämpas så tidigt sommöjligt i produktutvecklingsprocessen. DFA2-metoden bör utnyttjas på produktnivå för attunderlätta konceptvalet och på komponentnivå för att göra produkterna/modulerna lämpade förautomatisk montering, detta innan designen är "låst" och innan en fysisk prototyp harkonstruerats. Avdelningar som ska arbeta med DFAA inkluderar produktion, designkvalitet ochinköp. När DFA blir rotad i företaget kommer dock fler funktioner i företagets supply chain attpåverkas. Det innebär att fler funktioner kan behöva inkluderas med arbetet kring DFAA.Slutligen så inkluderar studien en beslutsmodell relaterat till DFAA. Besluten baseras på demätbara värden från DFA2-metoden.
