LSI-11/23 PERT General Calculating Program

This paper describes the realization of PERT general calculahing pragram in FORTRAN languege on an LSI-11/23 computer. It discusses how to find the key line of the PERT, computing the time parameter for different engineering peried, and the distribution table of realizable probability for different overall periods. In addition, a practical example of calculation is given and tentative improvement in five aspects are proposed.
