    ENGLISH ABSTRACT: In order to do proper long-term planning for major capital projects which are funded collectively by a central body (e.g. the government), input is required from strategic level as well as from project managers at tactical level to ensure that planning requirements are included from all levels of management. This input is processed by means of a heuristic capital planning and decision support model so that the results, which comply with most of the given constraints, can indicate financial and other impacts on all role players during the execution of the capital project. Through this, good decisions can be made with regard to the projects and investments. At strategic level, budgets, requirements· and priorities of the various projects are taken into consideration, while at tactical level, schedules, project and subproject cash flow predictions are calculated. With this a chosen schedule can be formulated. The impact of the chosen schedule on human resources and various engineering functions can be evaluated, after which sensitivity analyses are conducted. After the completion of sensitivity analyses, decision makers at strategic level can accept an appropriate near optimal macro schedule. Hereafter the final results are made available to decision makers and executors at tactical level. Insight into long-term cash flow requirements can be derived from the available information. All the major capital projects can be scheduled and the requirements in terms of high-level manpower can be determined so that strategic decisions can be made. Owing to the complexity of the model, which results from the many possible combinations that may occur, a heuristic approach is proposed for doing the capital planning. The impact on various factors, for example the impact on human resources, is determined from the schedule results. Any changes that might be necessitated by the schedule results can be negotiated with the role players, based on the output of the programme.
