abstract = "The objective of the project was to develop the long-distance transportation of forest chips by means of better transport economy and control of logistics activities. Different loading methods were tested to make the load sufficiently compact and to intensify the use of load space of the chip trucks. The usability of mobile positioning devices was tested in the operational environment of forest chips procurement. The arrivals and inbound logistics activities of power plant were modeled by aid of simulation model to estimate the queuing time of chip trucks with alternative course of action. According to the follow-up study of chip trucks and simulation of receiving activities substantial developing potential was found to decrease the terminal times of trucks both in loading stage at forest terminal and unloading stage at power plant receiving area. By trucks with interchangeable containers terminal times can be decreased by developing the logistics of production chain for example by means of the pilot production control system evaluated in the project or by dimensioning the capacity of whole chain to match better for prevailing operational environment. With shorter distances the number of containers or the trailer size can be designed for smaller volume whereas with longer distances the transport economy will be emphasized. The capacity of weight limited the load size except for summer period alongside with dry forest chips. Instead of maximize the load volume, more essential will be to decrease the unloaded weight and effectiveness of loading and unloading stage. Loading method, where belt conveyor was equipped with mechanical ejector, compressed the load some 15% compared with blowing device. The energy consumption was also essentially lower. The pilot-period of production control system showed that the mobile positioning devices and digital maps will improve the planning and control activities of forest chip production. When the procurement amounts of forest chips will increase, the advantage of utilization of such systems will be greater.",
