This study investigates the use of Analytic Hierarchy Process (AHP) in customer retention decisions in the Nigerian telecommunication industry using a cross-sectional survey design. Primary data were obtained through questionnaires administered to 480 mobile telecommunications subscribers in six tertiary institutions located in Lagos State, Nigeria. These educational institutions were chosen using a multistage sampling technique. Of 438 questionnaires received from subscribers, 408 were valid. Based on this sample data an AHP model was built to assess the determinants of customer retention decisions. Next, eigen values, an eigen vector and maximum lambda (λMax) were obtained using the AHP analysis for the matrices. This analysis shows that customers considered call quality as the important in the retention decision. We conclude that AHP is a meaningful tool for determining what motivates retention decisions, that can help network operators formulate effective customer retention strategies.

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.
- ItemOpen AccessAssessment of Knowledge Sharing Factors among Academic staff in Nigerian Universities(Journal on Efficiency and Responsibility in Education and Science, 2019) Oyenuga, O.G.; Adebiyi, S.O.; Mustapha, D.O.; Abimbola, B.O.As a core process to knowledge management that aids innovation and regeneration of knowledge among individuals within institutions, knowledge sharing cannot be overemphasized owing to its importance in gaining a competitive edge and sustaining competitive advantage. Therefore, as the citadel of learning, academic institutions need to measure the factors that influence knowledge sharing among their scholars using approved multi-criteria models such as the analytic network process (ANP) in order to formulate and implement research-driven strategies for sharing knowledge in a way that global competitiveness will be enhanced. The research design is quantitative and analytical in nature through a survey of experts (Lecturers) with the usage of a pairwise comparison questionnaire. The sample was drawn through a multi-stage sampling procedure and 102 copies of questionnaires were retrieved and found fit for analysis. In addition, Ardichvili’s framework of factors contributing to knowledge sharing was adapted within the Nigerian cultural setting in order to widen the scope of knowledge. Data collected were modelled into clusters in line with the ANP technique. The results show that respondents believe that institutional norms factors were better motivators for knowledge sharing of which institutional culture stand out. In spite of the available organizational barriers, academia believes that individual barriers are disastrous to knowledge sharing.

This study examines the use of a multi-criteria decision-making method using the analytic network process (ANP) to estimate how supply chain activities of the selected manufacturing firms’ influences its firm performance in other to enhance the satisfaction of customers. The population of the study is the manufacturing firms quoted in the Nigeria stock exchange. An ANP-based questionnaire was administered to Managers of selected manufacturing firms for pairwise comparison of supply chain factors relative influences and dependencies on their customers. A nonlinear network model was built to capture all the factors of supply chain practices and firms performance into clusters, nodes and dependences for the purpose of estimating various influences of supply chain practices on the performance of the various companies studied. Data collected were analysed using the software of Super decision 3.0version. The results revealed factors of supply chain practices that have a great connection with one another and strong relationship indicating that without the implementation of the key factors of the supply chain there would not be a significant improvement in the performance of the organisation which will also affect the desire of the customers. The ANP model has helped to show the interdependencies and feedback among the various factors of practices of the supply chain to augment the level of performance of the firms.
- ItemOpen AccessPrioritisation of Ferry Commuters' needs in Lagos Metropolis: An Analytical Hierarchical Process Approach(Scientific Journal of Silesian University of Technology, Series Transport, 2020) Hart, E. C.; Adebiyi, S.O.; Oyenuga, O.G.Understanding the needs of ferry service commuters cannot be overemphasis, considering the fact that the survival of any business largely depends on the volume of its customer base, and how well they are satisfied with the level of services received. More so, owing to the high population of Lagos state and usual traffic congestion across main roads during the peak periods, water transportation via ferries undoubtedly becomes a viable alternative to ensure stakeholders satisfaction in urban planning for a city majorly surrounded by water providers. Thus, this study employs the analytical hierarchy process (AHP) to prioritise the ferry services needs of commuters to make effective managerial decisions that will aid efficiency in their operations, thereby, increasing the market penetration, competitive edge and commuter satisfaction. A sample size of two hundred and four was computed through purposive sampling procedure. The data retrieved were analysed using pairwise comparison in line with AHP methodology. The study found out that among the criteria measured, comfort was perceived more important to commuters compared to its pairs. In addition, recreational facilities, ease of online payment, regular maintenance of waterways and seating with good legroom were ranked high by the commuters. Therefore, to ensure a sustainable competitive advantage over other modes of transportation, these indicators need to be effectively considered in water transportation policy.
