This report, Volume 8 of the 11-volume report on the master design simulator (MDS), describes the cost subsystem. This subsystem provides for the projection of costs and investment of operations over time using data generated by the MDS subsystems and data libraries. This model incorporates a direct costing feature for use in conjunction with the MDS, and considers labor, capital, and operating costs. While the model is capable of independent use, the direct costing of supplies and other operating elements are sacrificed in the absence of the MDS. The model generates cost reports covering each shift of operation for each mining section. Optionally, cost summaries are generated for each day, each month, and each year of operation. Finally, a discounted cash flow analysis is performed to determine the selling price of the coal mines. The report includes detailed instructions for operating the model and a program listing.
