The globalization has increased the trade between different places and countries. Products are now available from all over the world, but this requires transports that have consequences in the environment as well as the economy. New professions are creates that do formality, organize, administrate and implement other businesses transports. Their operations are between the business and customer and they are called logistics companies. The purpose of this report was to study third-party logistics and why more and more companies use this logistics services. A literature study was done to research This. The study is based on a literature work in the field of logistics by using books, articles and the Internet. The report also studied whether there are differences between terms within third-party logistics from 1980-90s and today. In third-party logistics it is emphasize to there is focus on using a logistics company as a good alternative for the companies who aren´t able to have a high quantity in their own vehicle. The purpose with route planning is to use the availability in the vehicle and try to have as high filling degree as possible. The filling degree is usually calculated on how much of the total area, volume or weight that is used.

Since the origin of the term third-party logistics in the 80-90s, the positive and negative aspects have been the same. But during the years more positive aspects have appeared. There are more positive aspects about third-party logistics than negative. Companies’ use and dependence of what third-party logistics can offer, have provided the companies with mostly positive aspects.

The logistics concept is more complex today that it was at its origin and it includes more activities. In the 90s, the concept forwarder was used to describe a person who coordinated the transports while the transporter was the one who executed the transports. By looking at outdated literature, we can presume that the future will bring more changes and that the role of respective parties will become even more unclear than they are today.

From the theory a deeper analysis was done in form of interviews with four third-logistics companies, to find out how transports work out in real life. The questions were classified in three groups; routes, filling degree and environment. The four companies worked constantly to improve the filling degree by different types of coordination and better loading, but also to by having goods in the return transport. Three of four companies thought that the transports were too cheap. A large number of goods are transported long distances back and forth. The logistics companies tried to offer their customers good customers service with cheap, fast and close transports in order to be competitive. We think that the logistics companies must take more responsibility and shouldn’t drive empty trucks, no matter the price they get. By a high filling rate the environments can be saved, because it will take fewer transports and it improves the company’s economy. The logistics companies of tomorrow have big challenges to overcome if they should continue a sustainable development that benefits their economic situation and the environment.
