Discussion of problems, techniques, trends, and possibilities of incentive contracting, with application to specific aerospace projects. It is stated that it is difficult to draw conclusions about a new and, in a sense, exploding development such as the one treated. The work undertaken to date by the DOD, NASA, and segments of industry promises future benefits. More and more sizable incentive contracts, with greater profit/loss possibilities, are certain. And the planning and execution of these contracts will demand a growing percentage of management's attention. It is noted that lack of sufficient management attention to incentives will preclude successful incentive contracting and thwart the benefits potentially obtainable.

VALUE ENGINEERING IN PROGRAM CONTRACTS.

S. Robinson (Radio Corporation of America, Missile and Surface Radar Div., Moorestown, N. J.).

Journal of Value Engineering, vol. 2, May 15, 1964, p. 61-66. Discussion of the Project Definition Phase (PDP) method of contracting, considered in a sense as an intensive value study conducted by all project activities. A significant aspect of PDP is the concept of system trade-offs among cost, performance, and schedules. A realistic and practical approach is to maximize capability for a specified cost or to minimize cost for a specified capability. The establishment of the PDP system is considered to have put value engineering into official government contracting policy. Various aspects of the problems involved are treated in detail.

ANCILLARY BENEFITS OF AN AUTOMATED R&D RESOURCES
ALLOCATION SYSTEM.

Ambrose B. Nutt (USAF, Systems Command, Research and Technology Div., Flight Dynamics Laboratory, Wright-Patterson AFB, Ohio).

American Society of Mechanical Engineers, Winter Annual Meeting and Energy Systems Exposition, New York, N. Y., Nov. 27-Dec. 1, 1966, Paper 66-WA/MGT-18. 9 p.

Members, $0.75; nonmembers, $1.50.

The ancillary benefits derived from use of an automated R and D resources allocation system are described, prefaced by a brief description of the system itself. The use of the system as an aid to management of a large Air Force R and D laboratory with a wide range of technical responsibilities is outlined. The several resultant benefits, exclusive of those related to resources allocation, are delineated and are shown to range from technical program data retrieval to vastly more knowledgeable planning at the task engineer level. These side benefits are concluded to be equally as useful to management as the basic system itself, which was designed originally only to be an aid to resources allocation. (Author)

Review of the current approach to selling research and development (R and D) and an attempt to relate it to the workings of related marketing areas. Some fundamental shortcomings of the current practice are pointed out, and a new approach is suggested to the problem. A new concept is introduced in the approach to marketing R and D capabilities to the defense/space market which is based primarily on establishing capability managers as the focal point of the managing function. It is suggested that this is only one of the several new concepts that are needed to meet the challenges of marketing. B. B.

RESEARCH PROJECT SELECTION TESTING A MODEL IN THE FIELD.

William H. Pound (Northwestern University, Technological Institute, Dept. of Industrial Engineering and Management Science, Evanston, Il.).

IEEE Transactions on Engineering Management, vol. EM-11, Mar. 1964, p. 16-22. 7 refs.

Results of a field test of a procedure for evaluating research projects. The procedure, based on what is termed an expectedvalue model, considers the following decision elements: (1) the environment of the problem, (2) the decision maker, (3) his objectives, and (4) his alternatives. The decision maker's alternatives, in this case a number of potential research projects, are evaluated in the light of his objectives. The result of the procedure is a ranking of potential projects in terms of their expected values.

This procedure was tested in a research laboratory by having four decision makers evaluate a selected list of research projects. The resulting ranking of the projects was found to agree with an intuitive evaluation by the decision makers of the same list of projects. This gives an indication that the expected-value model may be useful in the complex area of research project selection.

Presentation and test of a model designed to explain the research and development investment decision of firms. An attempt

is made to explain the role of certain variables after isolating other variables that are not specified in the model. Estimates are made of the departure from the desired level of research and development expenditure and the coefficients of important variables that cause deviations from the level. The main variables discussed are profits, sales changes, expected sales changes, and expected capacity changes. The statistical method used to estimate the parameters of the variables is multiple regression analysis. On the basis of the analysis, several hypotheses are proposed and discussed in relation to alternative hypotheses.

IN: Science, Technology, and Management. New York, McGrawHill Book Co., Inc., 1963, p. 49-60.

Presentation of information concerning the current conduct of DOD research and engineering activities. Management of research in the defense establishment is studied. It is shown that management provides the broad environmental influences wherein scientific programs can take place and technical decisions can be made which

culminate in major scientific breakthroughs. It is suggested that management should not restrict creative ideas in the initial stages of a program, but should provide wide latitude for research and experimentation. However, it is pointed out that this process of maintaining flexibility and a number of avenues cannot continue through the later processes of engineering and development. At these stages, objectives have to be clearly defined and parameters established; the decision-making process is then more clearly defined. The current problems of the DOD in performing its functions are reviewed, and the actual management of the Office of Defense Research and Engineering program is discussed in detail.

VALUE ANALYSIS AS A WORKING TOOL.

H. Davies (Thiokol Chemical Corp., Reaction Motors Div., Denville, N. J.).

Chartered Mechanical Engineer, vol. 13, Feb. 1966, p. 60-64. 7 refs. Review of value analysis as a management technique that results in cost reduction. The example discussed is the application of the technique to the production of the Bullpup A and B missiles, both of which were already in service when the technique was applied. It is shown that in the case of production programs which are contracted out on a successive basis, value analysis provides an effective tool for improving competitive efficiency. The manner of organization of the value analysis technique with respect to existing company structure and departments is explained. The importance of supplier participation is emphasized. Two small components a pintle (used as a flame holder and turbulence increasing device in the injector area of the combustion chamber) and a small plug are cited as specific examples where the technique permitted significant cost reductions. A check on production records shows that value analysis reduces cost without causing any reduction in quality and reliability.

The Engineer, vol. 221, Jan. 28, 1966, p. 170-172.

Discussion of the relatively simple basic principles of simulation which can represent an extremely complex, managing policy. It is noted that a simulation imitates an industrial situation by converting it into a mathematical model and that, whereas it is usually impos sible to experiment with an actual situation, to see for example the effect on costs of varying production rates or the effect on stock levels of varying ordering policies, it is possible to experiment as one wishes with a mathematical model, once it has been proved to be an accurate simulation, and arrive at an optimum policy. It is pointed out that one of the most remarkable examples of simulations from industry concerned a textile mill in which the highly complex rules that governed the running of the mill, many of which had become buried in the subconscious minds of the heads of the departments, were converted to a mathematical simulation model which so impressed the managers with its faithful reproduction of policy that they arranged to use it for the basis of their weekly planning meeting.

A description of the techniques applicable to the construction of models in linear programing, with particular application to management and social science. The need for distinguishing between a problem and the way it might be modeled is stressed, as, for example, in the search for intersections between the wanted solutions of a nonlinear problem and a linear model constructed to deal with it. Model equivalents that can be obtained by effecting various transformations are discussed. These transformations, together with the properties of a constrained optimization, can be used to obtain still further extensions - for example, when obtaining the replacement of a compound objective with a simpler objective, in order to deal with a larger problem in engineering design. Techniques for characterizing the rank of a matrix, applying duality to linear programing, using constrained regressions for algorithmic completion, and extending the simplex method to algorithmic alterations are described.

Discussion of the role of the government laboratory in the Program Definition Phase (PDP) environment. Emphasis is placed on the dual task of defining the technical boundaries of the problem, and evaluating the PDP reports to select the most acceptable engineering approach. The problem of accomplishing a detailed technical evaluation of several proposed approaches in a short time frame is examined, with the result that a requirement for a better "yardstick" is established. Design decisions leading to the final specification of such a yardstick - the Tactical Avionics System Simulator (TASS) and a summary of its anticipated capabilities are presented. (Author) V.P.
