An automated Economic Analysis Model computer program designed to aid equipment procurement decisions is described in this report. Net present value, equivalent uniform annual cost, break even points, and savings to investment ratio output are presented in graphical form. Sensitivity analyses presented include lease vs. procurement, varying recurring costs, and varying differential inflation rates. The program was originally developed in China Lake, California on a UNIVAC computer, but was converted by DTNSRDC to run on its Burroughs B7700 computer. Only the converted version is described in this report. Included, are references to the documentation of the original UNIVAC version of the program. Although the program was originally designed for equipment procurement, it was successfully used for an economic analysis of an automated data processing system. (Author)

This thesis discusses the modification of aid additions to an existing Optimal Systems Control FORTE AN Program (OPTSYS) originally obtained from Professor Arthur E. Bryson of Stanford University and subsequently redesigned to run interactively on the IBM 33 33 VVCMS by Lieutenant Commander John G. Hoden of the Naval Postgraduate School (NPS). The modified FOBTEAN program (OPTSYSX) and the additional FOETEAN Programs (OPTCALC) and (OPTPLOT) are now designed to run interactively under VM/CMS on the IBM 3033 utilizing a library double precision numerical integration subroutine and high resolution precision plotting software to provide the user with a highly accurate time response of a system which has been designed on the OPTSYSX Program. This series of programs permits the user to rapidly design, analyze and test all types of Optimal Systems Co ntrol problems. Examples of the various types of problems are worked through to illustrate all of the capabilities available., http://archive.org/details/developmentofgra1094519259, Commander, United States Navy, Approved for public release; distribution is unlimited.
