Abstract

One of the most important decisions that a surveyor has to make before embarking on a given surveying project is the selection of the instrument. Where there are number of choices, a decision by way of selection has to be made. The selection can be based on a number of criteria, for instance, accuracy, cost, user friendly, size of project, user knowledge and experience, project type and duration. The need to have the best equipment for the right job cannot be overemphasized. This requires that the surveyor should select the equipment to be used in an objective way, taking into cognizance all factors and their priorities. The aim of this paper is to demonstrate the use of the Analytical Hierarchy Process (AHP) as a form of decision-making methodology in the selection of equipment for a surveying project. Priority weights for each factor controlling the choice are also determined. 3 instruments were considered for selection – Total station, DGPS and theodolite and 7 elements used in the instrument selection - accuracy, cost, user friendly, size of project, experience/ knowledge, project type and duration. The accuracy of the equipment appears to be the element with the highest importance. While experience and knowledge accounted for the next element on the level of importance. The element with the least importance user friendly element.
