The CALCULATION and economic interpretation of alternative solutions and sub‐optimal solutions to the transportation problem of linear programming are discussed and illustrated with particular reference to their application in the Soviet wood‐processing industry.

This paper investigates a specific problem, namely the ability of Soviet regional timber resources, p a r t i c u l w o s e of Northern European Russia and Siberia, to sustain the demands expected to be placed on them by world and domestic markets in 1990, the final year of the fifteen-year intermediate-future planning or forecasting period now guiding much of the national and spatial development of the Soviet economy. Contrary to the findings of other studies, this analysis suggests that the Soviet forest resource has sufficient potential to satisfy all planned domestic requirements and a large share of foreign demand in 1990, and in the years immediately following that date, if technological improvements in the comprehensive use of roundwood continue to be made in the Soviet wood-processing industry. When expected 1990 Soviet timber exports are compared to the United Nation's estimate of world demand for Soviet timber in the year 2000, the USSR appears able to fulfill but not to overwhelm most potential world demand for its timber although world markets will likely continue to secure a significant portion of their coniferous timber needs from North American, especially Canadian, forests.

Cet article analyse un problème particulier, celui de la capacité des Sovietiques en ressources locales de bois de charpente, en particulier en Russie d'Europe du Nord et en Siberie, pouvant repondre à la demande mondiale et à leurs propres besoins en 1990, dernière année d'un plan à quinze ans, à moyen terme et d'une pèriode de previsions interessant une bonne partie du developpement de I'économie Sovietique. Contrairement aux idées géneralement admises, cette analyse suggère que les ressources forestières Sovietiques ont un potentiel suffisant pour satisfaire à tous les besoins interieurs prévisibles à une bonne partie de la demande étrangère en 1990 et dans les années immediatement à venir, si l'industrie Sovietique du bois continue à réaliser des améliorations technologiques dans l'utilisation à bon escient du bois en rondin. La comparaison des exportirtions Soviétiques previsibles, en bois de charpente avec l'estimation des "Nations Unies," de la demande mondiale en bois de charpente Sovietique en l'an 2000, permet de pense que l'U.R.S.S. parait capable de faire face, mais pas beaucoup plus, à une grande partie de la demande mondiale en bois de charpente alors que les marchés mondiaux continueront vraisemblablement à garantir une partie significative de leurs besoins en bois de conifère, à partir des forets nord Américaines et specialement du Canada.

This paper evaluates nine elements, comprised of 233 entrepreneurs' locational attitudes in two Canadian metropolitan centers, for evidence that perception of the same region differs according to metropolitan location, and that locational images are related to specific types of manufacturing activity. Hierarchical cluster analysis is used to group attitudes that entrepreneurs hold toward their regional economic environments into patterns of similarity, and to provide visual and quantitative evidence for the level at which various firms enter a group, and the number of alternative groupings which are undertaken before any two firms comprise the same group. The paper concludes that a single ‘regional economic milieu’ does not exist for all entrepreneurs inhabiting the same regional location, that entrepreneurs' attitudes differ between and within the region's two metropolitan centers, and that decisionmakers perceive regional location opportunities as individuals, according to their personal needs and those of their firm (but not of their industry).
