input linkages is germane to planning for coal mine capacity expansions. Zimmerman (1979) suggests a probabilistic approach to measure underground coal mine productivity. Output per section is to be explained by seam thickness and the number of working sections. The seam thickness itself is assumed to follow a lognormal probability distribution.
