Log cost allocation for multiple mill merchandising systems

Creator:: Leatherman, Louis M.
Abstract:: Co-located mills that share a log resource through a single merchandising facility are challenged with the task of allocating the costs of joint-products in order to determine log cost for each mill during a given period. While allocating joint-costs is inherently arbitrary, some allocation must be made to include raw...
