摘要:

AbstractA ship fleet management problem is described which concerns the phasing out of a fleet of general cargo ships over a 10-year period with the possibility of premature sale and temporary replacement by charter ships. The objective is to determine a sale and replacement policy which maximizes long term company assets. The problem is tackled by selecting a priority order for sale and determining the optimal rate of replacement by dynamic programming. The method has been programmed and demonstrated good returns and is in current use by a shipping company for a variety of management functions.

摘要:

AbstractA procedure is described for investigating optimum running conditions for a thermal power station.The solution was obtained by the application of mixed integer programming: by the same method, various possible extensions to capacity were examined which involved evaluating twenty additional combinations of boilers and turbines.

摘要:

AbstractA method is proposed for calculating the number of Near Mid-Air Collisions to be expected in a volume of airspace about which the traffic patterns are known. Whilst not providing absolute predictions, because of the difficulty of modelling the human elements in such a system, the technique does enable those areas of particular air traffic control complexity to be highlighted.

摘要:

AbstractThis paper contributes to the literature on the problem of allocation of resources to a set of risky investments. Our objective is to develop the ideas in the context of a research and development laboratory. A mathematical programming approach to the resource allocation problem is taken, and various forms for an objective function under risk are discussed. A probabilistic objective function appropriate to R&D is isolated and tested on a small hypothetical example. Parametric linear programming is used to yield a near-optimum allocation.

摘要:

AbstractA programming model of project selection is extended to include the issue of new equity as one of the activities.This allows the marginal cost of capital, in each year up to a planning horizon, to be determined within the model.It also allows pre-horizon decisions to be uncoupled, under plausible assumptions, from the consideration of post-horizon opportunities.The model is used to specify optimal joint strategies for financing and investment, and to analyse complex projects-e.g. acquisitions-which affect both financial structure and the supply of profitable opportunities. Interactions between project selection, financing policy and dividend policy are illustrated and the results are contrasted with those derived from familiar decision-rules.
