AbstractIf a linear programming problem involves two objective functions, it is desirable to learn all solutions depending on the relative weight attached to the two functions. This paper presents details of an algorithm which finds these solutions systematically.

摘要:

AbstractThe general problem of a marksman versus a mobile target, with a time lag in the gunner's information as to the target's position, appears in many guises in many situations. It is a classic military problem. Formulated in terms of game theory, the desiderata are: How should the target best maneuver to confound prediction of his positions How and when should the marksman make this prediction? What hit probability is to be expected when both participants behave optimally?This paper discusses this general class of problems and then settles on one which seems to be the simplest possible example that is not trivial. Nevertheless it is difficult. In two previous papers devoted to it, the evader's best strategy and value of the game were given. Here the emphasis is on the marksman. He has no optimal strategy, but does have an ideal strategy with the property that every near optimal strategy is close to it. He also has a class of passive ε‐strategies such that if and only if he obeys their dictates will he either come within ε of the best hit probability or else always remain in a position where it is possible to do

摘要:

AbstractThis is a mathematical and statistical study of the supply operations at a typical Air Force base. The objective of the study is to determine the effect upon support cost of different logistics policies, involving changes in safety level and requisitioning frequency. This effect is found to vary according to the price and demand rate of the item being considered, and the study indicates that large monetary savings can be realized by adopting different stocking and requiritioning policies dependent upon item demand and price. Thus, the study indicates that it is more economical to have items costing under $10 requisitioned from the depot every three or six months, rather than every month, even if obsolescence charges on base stocks are as high as 50 per cent per year. The study has also indicated that standby stockage of cheap (under $10), low demand items is desirable because the cost of such stockage tends to be less than the costs incurred by premium supply action when a demand for such an item ariees.

摘要:

AbstractAssuming that numerical scores are available for the performance of each of n persons on each of n jobs, the “assignment problem” is the quest for an assignment of persons to jobs so that the sum of the n scores so obtained is as large as possible. It is shown that ideas latent in the work of two Hungarian mathematicians may be exploited to yield a new method of solving this prob

摘要:

AbstractIf money is spent too fast while stockpiling for a contingency, production may be highly inefficient. If it is spent too slowly, there may be too little stockpile when the contingency comes. The problem of finding an optimum spending rate in one of these situations is discussed.

摘要:

AbstractA study of cargo handling methods required a re‐evaluation of a standard work sampling technique. The most interesting conclusion can be qualitatively summarized as follows: if there is evidence that the process lacks any prominent periodic component, then it is better to sample at fixed periods than at rando
