Abstract
The rationalization of working procedures during difficult market conditions is gaining increasing importance. For rational production, it is necessary to always be aware of what and how much to invest in the business process to obtain the desired products or services without economic loss. This article presents a tool for the assessment of costs in forest wood supply chains. WoodChainManager is a Web-based tool composed of three user modules intended for the assessment of material costs of individual machines or the total costs of all selected machines in a forest harvesting system. Users can test the impact of individual technologies on the total material costs of the harvesting system and thus optimize operation processes. The basic tool for describing harvesting systems is the matrix, which visualizes cutting and hauling from the standing tree in the stand to the forest products at the end user. The tool has built-in algorithms that prevent the selection of an illogical harvesting system. The selected method for calculating costs for individual machines is simple, but still reflects the state of the actually incurred costs. WoodChainManager offers cost calculations for a wide range of technologies, machines and appurtenant attachments. The authors of this paper wish to increase awareness and understanding of cost calculations and to offer the possibility to directly compare different harvesting systems.
Highlights
Forestry as a branch of industry is not intended to be an end in itself, but regarded as one of the links in the complex forest wood supply chain
Is an example of WCM cost calculations
One should again refer to the cost calculations in order to select the most economically efficient harvesting system
Summary
Forestry as a branch of industry is not intended to be an end in itself, but regarded as one of the links in the complex forest wood supply chain. The forestry links of the forest wood supply chain are made up of a series of production processes through which the natural resources from forests are transformed into products and services (Triplat et al 2013). Similar to all other branches of industry, the objective of timber production is to select the most rational working techniques and procedures and the most comprehensive technological solutions. The cost of labour per unit time and productivity determine the price, which is the basis for comparison of different harvesting systems (Krč and Košir 2004). Calculations enable the comparison of individual and total costs between products or services
