Thus the need for operations research model (AHP) to evaluate customer preference of their mobile telecommunication attributes so as to direct policy and strategies at what is/are important to subscribers whom were the essence of business activities. The paper built hierarchical model for choice/determinant of subscribers' preference for mobile telecommunication attributes in Nigeria as the goal, using seven main attributes as the criteria for evaluation, while the four main players in the GSM market (MTN, Airtel, Glo and Etisalat) are the alternatives. An AHP based questionnaires was administered and distributed among student of tertiary institutions in Lagos. Out of the four hundred questionnaires distributed, only three hundred and eighty six were duly filled, returned and found suitable for the analysis. The data was analyzed, considering the set of evaluation criteria (service attributes), and a set of alternative (network providers) scenarios among which the best decision is to be made. We generated a weight for each evaluation criterion and scenario according to the information provided by the decision makers (stakeholders). AHP was used to combine the objective and scenario evaluations to determine the ranking for scenarios. The result reveals that an average student preferred network providers with low rates (affordable) follow by quality of connections and reliable data plan for internet service. The priority was done for the criteria to direct strategic decisions in the telecommunication industry towards meeting subscribers' needs. Coverage was not given significant priority as the respondents assumed that all providers have similar coverage. This result of this study will assist at improving the quality of decision making of stakeholders.

Nigeria Ports are characterized with incessant congestion problem in the recent past. This has resulted in diversion of ships scheduled for Nigeria Ports to other neighbouring country ports which has caused the country to lose a lot of revenue. The effectiveness of a Port is contingent upon loading and unloading of ships. The traffic movement through a port is a complex phenomenon because of the random nature of the arrival and service time of the ships. This requires a systematic approach in port planning and management. Queuing model was applied to the arrival and services pattern which causes the problems of congestion and proffer solutions to the problem areas. It is also used to predict the average arrival rate of ships to Tin Can Island Port and the average service rate per ship in a month. The study to found out the number of berth in Nigeria port is adequate for the traffic intensity of vessels but other factors leading to port congestion were identified through the content analysis of the interview conducted with stakeholders at the port. Policy recommendations that could make Nigerian ports to be cost effective, more attractive and enhance quick turnaround of vessels at the ports were made.
