Administrative transportation: En route to cost, quality and convenience
James Campbell and Alberto Canen This article is concerned with the study of administrative transportation for a large Brazilian industrial company. The problem context is discussed together with the present approach and the conflicts that arose during the development of this research. A description is also given of the various OR methodologies used to reach the final recommendations.
Throughout the past fourteen years the company has been dependent upon the supply of drivers, buses and maintenance crews from a single transport contractor. Responsibility for the construction of the company's
present routing strategy rested with the transport contractor who dictated the precise routes and

The analysis involved three broad steps. The first of these involved interviewing the client group (senior managers of the company's Administrative Department), in order to define the problem context. The second step involved cognitive mapping to express and explore argumentation underlying the problem. Finally, the third step was to carry out a data analysis aimed at identifying the areas for improvement. For presentation purposes the above three steps are presented in order, but in practice work tended to switch more freely between one activity and another, in a fluid and adaptive way.
