Telecommunication and mobile phone usage for that matter have assumed a centre stage in the Ghanaian economy like any other economy the world over to a degree that its possession is increasingly becoming a necessity. The objectives of this thesis are to model the selection of the best telecom network as a decision problem as well as identify the best telecommunication network out of five available telecom networks in the Greater Accra region. These five networks are represented as: A1, A2, A3, A4, and A5. The model used to represent this problem is the decision model and the method employed is the PROMETHEE method. The National Communications Authority (NCA) has provided four major criteria for measuring the performance of the various networks. They include: Call Setup Time; Call Completion Rate; Call Congestion Rate and Call Drop Rate. Using the PROMETHEE methodology as a multiple criteria optimization technique, the five mentioned alternative networks are analyzed based on the above mentioned four criteria. However, a simple illustration of the single criterion optimization technique on this multicriteria decision problem is made to expose the inefficiency of the approach in solving such a multicriteria decision problem. The generalized preference function that is chosen for this study is the Gaussian preference function. Through this, partial and complete ranking of the alternatives are made to depict their performance from best to worst. Finally, upon the outcome of the analysis, the ranking is as follows: A2, A4, A5, A1, and A3. Hence, the best network is A2 and the worst is A3.
