Background and Purpose: The potential impact that climate change may have on fire regime in ecosystems that are not fire-dependent emerges from fires that are nowadays spreading over higher altitudes and northern latitudes. The effects of fire occurrence in high elevation forests of Greece became apparent during the last few years when a number of large forest fires burned a significant number ...

This paper describes operational research (OR) contributions in forestry over the past 50 years, based on scientific pathways along which authors have traveled. We draw our personal experiences and recall how use of OR has evolved from early linear programming Canadian forest products industry 1950s strategic management planning by U.S. Forest Service 1960s. describe widespread many aspects a 5...

In this paper, we present a mathematical programming model based on a timespace network representation for solving real-time transportation problems in forestry. We cover a wide range of unforeseen events that may disrupt the planned transportation operations (e.g., delays, changes in the demand and changes in the topology of the transportation network). Although each of these events has differ...
