| Tiivistelmä: | Recent work on validation has demonstrated the paucity of validation in operational research projects. The processes of mathematical model-building and validation are considered as a function of the level of contact between the modeller and the decision-maker. The contention is that different levels of contact require emphasis on different types of validation. Examples, mainly from case studies involving linear programming, are used to reinforce the statements. The form taken by the validation processes may be considered as a series of questions that the user of the model should address to the appropriate intermediary or modeller. In addition, it is shown that new modelling software tools coming onto the market alter the way of validation. |
