Assessment of Costs in Harvesting Systems Using WoodChainManager Web-based Tool

volume: 41, issue: 1

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

A System for Quality Assessment of Forestry Contractors

volume: 42, issue:

Skilled contractors are needed to meet the increased demand for wood and to maintain a competitive edge in forestry. The structure of the forest industry has changed significantly. Today’s situation favours smaller contractors that are more flexible. Worldwide contractors are important for forest operations, but there is often limited knowledge about how well they fulfil demands about resource efficiency, social responsibility and environmental protection. The aim of this paper is to present the guidelines for the assessment of forestry contractors following sustainability principles and to present a recently developed system. In addition to the requirements for professional competences and legislative obligations, the system proposes a number of additional requirements such as corporate social responsibility, participation in the local community and greater environmental responsibility. The forestry contractor and the certification body sign a cooperation agreement to obtain the expert assessment. The expert assessment is performed by an evaluator authorised by a certification body. A web service has been introduced with the purpose of serving as a communication tool between professional evaluators and forestry contractors, as well as providing a new possibility for forest owners to get direct contact with forestry contractors. The system enables its users to exert influence on the assessment of forestry contractors by assessing the quality of their services. Private forests would greatly benefit from customer feedback information on the service quality. By now, 1584 forest contractors have registered in Slovenia, where 67% provide the service of cutting and skidding, 8% provide woodchipper service, 7% transport of round wood, 5% cable crane yarding and 4% fully mechanised harvesting. Until June 2020, 142 forest contractors have gone through the process of quality assessment.
