H I S new series is intended to review published d a t a and techniques for estimating chemical engineeiing capital investment, manufacturing cost, and profitability. An almost complete seriea of bibliographies, for both chemical manufacturing and petroleum refining, covers publications through 1954 (1L, ZL, 5L, 6 L ) . Reprinted compilations of articles ( 2 K , SIC, 6 K ) are also available with some of the basic publications in this relatively young field. T h e attached bibliography is annotated briefly t o supplement this section of discussion, and an alphabetic subject index is also provided. TTOcomplete texts on different phases of chemical engineeiing economics ( l K , 7 K ) and several books containing relevant sections (lOD, 4K, 5K, 8 K ) appeared during the year. Certainly the outstanding addition was by Schn-eyer (7K)-the first booklength study for chemical engineers of engineering economics. Mechanical and industrial engineers have long since had texts available, with examples in their own field, describing the principles of economy, interest, economic balance, break-even charts, and manufacturing cost relationships. T h e Schweyer text is generally good, b u t somewhat ambiguous on profitability. It first properly relates rate of return on investment to interest earning r a t e b u t then introduces less exact measuies (p. 164) which are called acceptable, although their answers a l e shown t o be in error. Aries and Newton ( 1 K ) offer an extensive compilation of d a t a on capital investment required for a x i d e range of equipment. T h e possible range of error resulting from use of their graphs should have been indicated more clearly. V i t h o u t more details on t h e source year for each d a t a point as 17-ell as d a t a on the cost index used to bring them to 1954 prices, t h e compilation can only b e used for very rough estimating. The section on piofitability suffers by comparison n i t h many of t h e discussions reviex-ed here. T h e y d o n o t insist t h a t working capital b r considered vvith fixed investment in such analysis. Other important contributions in book form weie t h e chapters in Ireson and G r a n t ( 5 K ) on “managerial economics” by Joel Dean and “engineering economy” by Paul Norton; the sections on (‘the time factor in costs and plofits,” and ”control of operations and investment” in Fiske and Beckett (4K);a revised printing of Grant’s fine text on depreciation ( 1 O D ) ; and t h e fourth edition of a pamphlet on engineering economy intended to assist chemical and other engineers seeking t o pass the New York professional engineering examination (8K). PROFITABILITY

very specific techniques, each Kith its persuasive adherents, have, continued t o appear in the periodical literature. The timehonored DLIPont system has been described again (IF)and seems instancae still to be in wide use by estimators in general-for (25E,41G, 1 5 N ) . Other systems non- being proposed have ~ I I common t h e advantage of taking into account t h e effect of tho time value of money. T h e “investor’s’’ or “discounted cash flow” method, 17-hich uses, as a measure of rate of return, the compound interest earning r a t e of t h e project, turned up in notably dissimilar publicatione ($?F,9F, IOF). Happel’s “ventureworth” method ( S F , @‘) and a related proposal (88‘)measure profitability as t h e present value in dollars of t,he lifetime earnings of t h e project after cost of capital as an interest rate has been applied. Scheuble ( 1 1 F ) presents a nomograph for equipnient replaccment which interrelates earnings, investment, minimum desired return on investment (interest rate). and cash-recovery period (pay-out time) for investment, plus interest’. YanagisaTYa (1BF) presents a nomograph for pay-out time including interest. T h e “capitalized cost’, system, well recognized in noncheniical texts on engineering economy, has been related to chemical eiigineering ( 6 F , 6 F ) . T h e system has also been compared with the “annual cost” method ( i F ) . i i n interesting discussion has arisen as to whether, in these techniques, annually compounded interest should be applied a t the beginning or the end of the year (6F). This difficulty might be avoided by continuous compounding, as recommended for other systems (WF:QF, IOF). Such application of continuous int’erest also better approximates the continuous influx and outflow of moneys t o and from a business enterprise. TECHNIQUES AND MISCELLANEOUS

h

fell- discussions of general estimating techniques and their usefulness are st’ill appearing (10E, 14E, IgE-WOE, %E, S2E, B M , 1 6 M ) ,along with studies of such familiar aids as breakeven charts (R?E pro, 2223 con), nomographs (16E), and statistical analysis ( I S E , %$E,31E). A number of new techniques have also been described. T h e operations-research t’echnique of h e x programing is apparently useful to estimators ( l E , 333). Smith and Dresser (29E)develop the applicability of incremental costs in estimat,es. Punched-card compilation of equipment. cost d a t a has been used to advantage (623, 8E). Other approaches should improve insight into run length ( J E ) , replacement to minimize cost ( 9 E ) ,penalty for partial capacity operation (I‘?‘E), and reduction of intangibles to numerical values ($023). Gitzendanner (11E, 1ZE) has proposed a novel method for analyzing the risks of various alternatives in order to minimize probable cost. T h e graphs are apparently printed incorrectly, b u t the approach is said to have merit (2E, Z S E ) .

COST ESTIMATION REVIEW Research and pilot plant economics and their relation to estimating have been analyzed from several points of view ( 6 M , 7 M , I J M , 1 9 M ) . T h e various methods for analyzing profitability prospects of research projects have been reviewed ( 1 6 M ) . Estimates are at times purposely made conservative; they may include n o t only contingency items but safety factors. Butler ( S M ) discusses t h e superiority of truly realistic appraisals. Productivity ( 8 M , I S M ) , sources of capital (9M,W O M ) , and price as a function of national product volume (ZTM, 2 I M ) have also been discussed. T h e choice of making or buying chemical ingredients has been reviewed ( 6 M ) . A new quarterly publication ( Z d M ) , though aimed at general engineering economic studies rather t h a n chemical engineering alone, should provide a valuable forum for publication and critical review. Cost indexes have been kept up to date (Section J of bibliography), and Kelson ( 5 J ) has reviewed the base costs on which his series of indexes ( 4 J ) are compiled. Nelson, one of t h e most prolific contributors t o t h e field of cost estimation ( 6 K ) ,has also started a new “cost-imating” series (35A-37A), so far devoted to equipment costs.

MANUFACTURING COST ESTIMATION

Two U. S. Government publications ( 2 0 , S D ) can assist in estimation of wages for areas of t h e country where t h e estimator’s company has no experience. Fringe benefits are largely a matter of company policy, b u t some available figures for t h e industry ( 6 D , 1.90) are useful guideposts. New d a t a also appeared which should assist in estimating: maintenance (5D, 9D,180, $ID), packaging (14D),materials handling (5B, 16D), chemical freight ( l l D , 19D, WSD), and administrative expense (WWD). The many references indexed under depreciation swell further the flow of books and articles on this subject since the revision of the 1954 tax laws. Estimation of depreciation costs often appears deceptively simple, since a company can establish a rigid project-life assumption with which all projects are compared for profitability. However, the actual depreciation allowance for tax purposes, t h e method of calculating depreciation by straightline or other methods, the expected process obsolescence, and the degree of specialization of t h e equipment involved will all affect the timing of a company’s earnings on a given product or process. Such relationships should be clear before a project is undertaken so t h a t the most profitable course, based on all available data, can be chosen.

PRODUCT COST DATA INVESTMENT D4TA

Considerable d a t a has appeared on investment and manufacturing costs for chemical and petroleum products (Sections G, H ) . Assumptions on which costs are based are usually stated in enough detail t o allow conversion to different utility costs, estimated plant life, etc., for use in varying circumstances. Konperiodical literature provided two significant contributions to the d a t a available on petrochemical costs (SG, SWG). As shown by the index, these cover in some detail a wide range of petrochemical products. It is interesting t h a t they are published, respectively, by a state and the National Government. T h e latter introduces a concept, not used in previous literature, relating labor requirement on a plant to the size of the plant. T h e “six-tenths factor” is >>-ellestablished for relating capital costs roughly to t h e ratio of capacities raised to t h e 0.6 or 0.7 power (dttE,bK). This new concept relates labor cost in dollars per year t o the ratio of capacities raised to fractional powers between 0.15 and 0.5. No substantiating d a t a for this technique is presented. The tendency is continuing, particularly in t h e petroleum journals, to publish d a t a t h a t have already appeared elsewhere (for instance, S1A-33AJ ZSG, i4G, 7”-9H). Better service might be provided by some sort of cross indexing or abstracting service which could in one journal summarize the contents of other journals each month and make unnecessary the regular reading of all of them.

Section A of the bibliography covers processing equipment; Section B covers auxiliary equipment such as piping, blowers, and instruments; Section C covers off-sitefacilities including utilities. Few of these items need to be discussed here in detail, since the index and t h e bibliography annotations are self-explanatory, Rauman’s (2C) comprehensive analyses of utility and off-site facilities, investment, and operating costs are worthy of special mention as a workmanlike compilation of d a t a from his company files. His work offers real assistance t o this country’s estimators. Many of our larger chemical and engineering companies must have considerable d a t a which, if correlated and published in this manner, would significantly improve t h e accuracy of estimations based on information from t h e literature. Some of the basic sources in t h e literature appeared in 1947-for instance, Chilton in (dK)-and reliability depends now on accurate choice of cost indexes as well as a n assumption of little technological advance in the last nine years. Faasen (10E) and Gore ( I S E ) have both referred t o the availability in company files of certain correlated equipment and plant cost d a t a which, either because of a restrictive company policy or because no author has volunteered his services, have never been published. Gore’s system for statistical analysis of past investment-cost d a t a allows preliminary investment estimation with a

JAMES BELLAMY WEAVER, 2nd, a chemical engineer, has chosen to specialize in a relatively new field-the economic phases of chemical engineering-and currently utilizes this experience as senior engineer in the Economics Evaluations Department of Atlas Powder Co. Weaver attended the Massachusetts Institute of Technology, receiving his B.S.Ch.E. there in 1944 and M.S. in 1947. From 1945 to 1950 Weaver served as an assistant to the director of research, Godfrey L. Cabot Co., and then before joining Atlas in 1954 was a techno-economist with the staff services research group of Olin Industries. Although chemical engineering economics has provided the material for most of his published papers, Weaver has also coauthored articles on soil chemistry. He is a registered professional engineer in Delaware and is active in the affairs of the ACS, AIChE, ASEE, and the Chemical Marketing Research Association. May 1956
