Developing planning models

Mr. Holloway joined the Gulf Oil Corporation in 1939. His previous publications are in the fields of chemical engineering, statistics and computing.He is now the Senior Adviser on Planning Systems and member of Gulf's European Planning Council.The paper presents the author's view that linear programming is an efficient vehicle for long range planning, that it is more comprehensive and when properly structured requires no more computer time than the perhaps more conventional simulation models.Further, that it has the great advantage that the planner himself can control not only the data content of his model, but can also control the way in which the data is treated within the model even to the extent of making drastic matrix changes.
