The purpose of this thesis was to create a strategic/tactical road access plan. This was done by designing an analytical method which gives the road manager a template to create long-term road access plans. The analytical method will help to identify and appraise roads to be upgraded and give information when it is time for building new roads. The study method involved developing an analytical method. The method was comprised of five main parts: the harvest plan, analysis of the road network, transport costs, quality and storage costs and finally, identification of investment alternatives. The harvest plan for a certain period of time is a very central part of the analytical method. Without it, it is almost impossible to create more long-term road access plans. A harvest plan with three harvest years was developed. Using the harvest plan as a starting point, analysis of the roads network was then performed. Here, the work for the road manager was simplified by learning of the various owners, road upkeep and in particular, the cost of improving, or alternatively the cost of building a new road. These costs were then compared with the costs for quarries. Quality costs and storage costs show what the closed roads during the spring thaw cost forest companies, and together with profits from transport savings due to the planned road improvement, they illustrate the viability of the investment. Unfortunately, the alternative road improvements which were suggested were not proved to be profitable. The results are three scenarios, where the first shows investment viability for each year of harvest. In the second and third scenarios, the idea was to se if it became profitable to improve roads to B and A level accessibility. The goal was to create the longest possible consecutive road network for the intended period and even for future harvests. The prerequisite was that quality and storage costs would decrease, otherwise no economical means would be available for the investment. As afore mentioned, the results were negative, but through further development of this study, the road access plans could become profitable. This could be achieved primarily through increasing the area included in the harvest plan and increasing the time perspective. If it were to be done, it would be easier to find a future "main-road", which hopefully would stretch through all of the harvest areas, thereby better dividing costs. Furthermore, a strategic/tactical road access plan gives the forest companies a clear overview and increased flexibility, which is important in this case. In addition, a "Just-In-Time" way of thinking can easier be used and increased consumer demands for high quality products can be achieved. Therefore, I see potential for creating profitable strategic and tactical road access plans. A final important point is that if future forestry is desired, which meets all the demand of the market, I find it to be very important to see the road access network as an essential part of forestry infrastructure, instead of a source of troublesome costs. If this opinion could be achieved, then automatically the strategic/tactical road access plans would become profitable.
