Abstract

Today, transportation network optimization has become one of the significant aspects of supply
chain planning, and even a slight rise in productivity can significantly reduce costs of
distribution of wood in the transportation network. In the forest based industry, given that
transportation is the main cost of raw wood supply, using transportation planning, distribution
should be done in a way so as to minimize the overall wood displacement. Such planning
must meet the needs of all demand centers and the distribution supplier points must be used
to their full capacity. Accordingly, the present study strived to find an optimal solution for
transportation and distribution of raw wood from the main supplier points to small and large
centers of wood and paper industries in Iran. This optimization simultaneously focuses on
several products and is at the macroeconomic level of the country wood market. To achieve
this goal, linear programming – Transportation Simplex Algorithm was used. The results
show a significant fall in transportation costs and a more organized wood distribution network
than the current situation. This cost reduction can be attributed to decisions about the optimal
distribution of wood types, determining transport routes, and opting for the right type of truck
supplier based on load tonnage and distance. This plummet in transportation costs plunges
the cost of wood and wood products, which will surge competition in the business and will be
of interest to manufacturers, distributors, customers and stakeholders in general.
