Method for requirement management within material management (English)
Abstract [sv]

Dagens industrier strävar efter kapitalrationaliseringar i form av bland annat effektivare materialhantering. Det gäller att i ett tidigt skede integrera produktutvecklingsstadiet och produktionsutvecklingen för att på så sätt få ett transparant system i hela ledet. För att kunna arbeta på det sättet krävs en grundlig och noggrann planering av hela processen.

Syftet med detta examensarbete är att ta fram ett underlag för beslut om transportlösningar och materialhantering. Ett annat syfte är att med hjälp av fallstudie observera olika transportlösningar och materialhantering som sker i olika system för att i sin tur kunna utveckla och ta fram en generell process för materialhantering. Fallstudien utfördes på företaget Scania, avdelning Scania Motorverkstad.

Examensarbetet inleddes med en grundläggande litteraturstudie. Huvuddelen av den empiri som samlades in skedde vid de nio intervjuer som genomfördes för de tre delområden som observerats. Syftet med dessa intervjuer var att ge ett fundament för fortskridning av utveckling på materialhanteringsprocessen.

Den empiriska studien följdes upp av ett resultat på en generell beslutsmodell för process materialhantering. Denna beslutsmodell består av en rad aktiviteter, objekt, informationskällor och direktiv. Varje aktivitet i processen presenterades ingående och utvecklades. Det är viktigt att olika aspekter beaktas i aktiviteterna, och sedan utvärderas för att kunna fatta ett primärt beslut i en aktivitet. Alla aktiviteter kommer att sammanställas som i slutändan ska utmynna i en färdigställd kravspecifikation för materialhanteringssystemet. Det har varit svårt med utveckling av materialhanteringssystemet då materialhantering inte prioriteras högt i produktionssystemet. Det har även varit svårt att hitta lämpliga lösningar på materialhantering då denna påbörjas sent i produktionsutvecklingen. Det optimala är att kontinuerligt arbeta med materialhanteringssystemet parallellt med produktionsutvecklingen för att kunna använda sig av diverse lösningar.

Den generella beslutsmodellen för materialhantering behöver fortsatt utvecklingsarbete då olika aktiviteter, informationskällor samt direktiv måste utvecklas ännu mer detaljerat.

Abstract [en]

Today’s modern industries are striving for capital rationalization by achieving more effective

material management. To gain a transparent system throughout the whole process, the product development stage along with the product development has to be integrated at an early point. In order for one to be able to work in this sort of way, a thorough and careful planning of the whole process is required.

The purpose of this thesis work is to build up a basis for decisions about transport solutions and material management. Also, another purpose is that being able to observe different transport solutions and material management that occur in different systems with the help of a case study can in order help to develop and assemble a general process for material management. The case study was performed at the department Scania Motor Workshop,

which is located in the company Scania.

The thesis work began with a detailed literature study. The main part of the empiric which was collected, took place at the nine interviews that were implemented for the three different part areas which have been observed. The purpose of these interviews was to set out a foundation to advance in the development of material management process.

The empirical process was followed up by a result of a general decision model for process material management. This decision model is sustained by different activities, objects, information sources, and instructions. Each activity in the process was thorough presented and developed. It is of high importance that every aspect is considered and thereby evaluated in order to make a primary decision in an activity. All activities are going to be compiled, which will result to a completed requirement specification for material management.

It has been very difficult with the development of material management system due to the reason that material management is not of high priority in the production system. In addition, it has been also difficult to find suitable solutions to material management because it begins later in the production development. The main is to continuously work with material management system parallel with the production development in order to be able to use different types of solutions.

Furthermore, the general decision model for material management requires a continued development work due to the reason that the different activities, information sources along

with instructions calls for a more detailed improvement.
