During the 1970s and 1980s, Sitka spruce (Picea sitchensis, Bong. Carr. ) was planted extensively on northern Vancouver Island (B. C., Canada) to regenerate slashburned clearcuts previously occupied by old-growth Thuja p1icata, Donn, Tsuga heterophy11a, Raf. Sarg., and an ericaceous unders tory shrub salal (Gaul ther ia sha11on, Pursh CH sites 1 ) . The planted Sitka spruce grew well initially on these sites, but experienced nutritional stress and reduced growth 8 to 14 yr after planting (Germain, 1985; Weetman et a1., 1990a, b). Accompanying the onset of the nutritional stress was the...

A central problem of prescriptive decision making is the mismatch between the elegant formal models of decision theory and the less elegant, informal thinking of decision makers, especially when dealing with ill-structured situations. This problem has been a central concern of the authors and their colleagues over the past two decades. They have wisely (to my mind) realized that any viable solution must be informed by a deep understanding of both the structural properties of alternative formalisms and the cognitive demands that they impose on decision makers. Considering the two in parallel...

1 Facility Location Problems The location problem has been with humans for all of their history. In the past, many rulers had the decision of locating their capital.

The development of industry involved location problems for production facilities and trade outlets. Obvious th criteria for location ofbusiness facilities includedprofit impact. In the 19 century, there seemed to be a focus on the cost of transporting raw materials versus the cost of transporting goods to...
