Item Open Access A comparative analysis of productivity and fare variations of Nigerian Airlines(U. P., 2017) Ejem, E. A.; Ekeugo, D. N.; Dike, C. U.; Chukwu, O.; Igboanusi, C. C.; Erumaka, O.This paper examined productivity variations occurring among different airlines In the study, quantitative techniques such as The pair-wise t-test was utilized in the analysis of the available seat kilometrage (ASK) performed by the various airlines within the study period. The study shows that, there were significant relationships between aircraft utilization, passengers operation and airline productivity, at 0.05 level. The relationship between fare and productivity was statistically insignificant at 0.05 level. There were also productivity variations occurring between different airlines selected for the study. We recommend that efforts should be made to quicken the time spent on the ground by aircrafts of various airlines operating in Nigeria, as less time spent by aircraft on the ground enhances aircraft utilization, which will in the main, boast productivity.Item Open Access Analysis of air traffic capacity in Nigrian airports(KY, 2017) Ejem, E. A.; Ibe, C. C.; Dike, D. N.; Chikwendu, D. U.; Igboanusi, C. C.; Chukwu, O. E.The paper is aimed at determining the capability of the airside facilities to accommodate aviation operational demand. The USA FAA methodology was utilized for the measurement of airfield capacity in this study. In consideration of the existing runway configuration, runway utilization patterns and 52506 operation counts, Lagos airport domestic wing Nigeria has been determined to have a daily demand ratio (D) of 240 operations and an hourly demand ratio (H) of 20 operations, and thus, an ASV of approximately 63006 operations. Capacity calculations indicated that a Nigerian runway configuration accommodates an ASV of 247, 123 annual operations. Based on the aircraft fleet mix currently utilizing Nigerian airports, this ASV seems appropriate through the planning period. The ASV during the period under study was highest at the domestic wing of Lagos Airport followed International wing of the same airport. Abuja domestic wing was next followed by Port Harcourt domestic wing. It is considered, therefore, that no significant increase to existing peak-hour runway capacity may be possible in the short term although there is spare capacity during the off-peak (shoulder) periods. Nigeria has, in theory, the option of having two additional runways available, to enhance the overall runway capacity of the airport. In practical terms, simultaneous operational use of these runways is unlikely to provide significant and consistent capacity benefits.Item Open Access Analysis of factors of delay in road construction and other projects in Imo State(U. P., 2017) Ejem, E. A.; Dike, D. N.; Njoku, L. C.; Onwuka, U.; Igboanusi, C. C.; Moneke, U. N.This paper is aimed at identifying various factors responsible for road construction delays. From literature 165 common factors causing delays were identified. A survey were carried out amongst selected experienced personnel for expert opinion to identify the significant factors causing road construction and other projects delays in Imo State, Nigeria. 436 responses were collected from each of the respondents groups including client, consultant and contractor covering the Senatorial zones of Imo State. The questionnaire responses were analyzed by exploratory factor analysis method, which resulted in identification of 58 common factors causing road construction delays. Results show that that Poor site practices exhibits the highest rotated loading factor 0.950, followed by Contractor selection method of 0.964, Delays in contractor’s progress payment by owner of 0.878, Excessive overtime of 0.959, Design changes by owner or his agent during road construction of 0.867, Uncooperative owners of 0.913, Weather effect of 0.869, Equipment failure of 0.861, Building permits approval process of 0.871, Materials changes in types and specifications during road construction of 0.803 and Transportation delays of 0.892 factor loading in technical, quality management, financing, human resources, changes, contractual relationships, environment, equipment, rules and regulations, materials and scheduling and control factors respectively.Item Open Access Exploratory factors analysis of human resources management strategies in the Nigerian Airline Industry(U. P., 2017) Ejem, E. A.; Dike, D. N.; Okoroji, L. I.; Igboanusi, C.t - The aftermath of liberalisation of the Nigerian aviation sector reveals itself in increasing demand for airline services at the Nigerian air terminals. The new competitive regime is seemingly a corollary of policy intervention to induce growth in quondam public dominated sub sector. Such impact will no doubt attract passenger services variance levels. The study examined factors which describe the critical variables that impinge on human resource management in a typical airline. To achieve some reduction in the categorical data points to deal with, while also investigating the structure of the data, we carried out an exploratory factor analysis. The analysis also serve the purpose of streamlining the study by removing highly correlated variables from the data set. The Principal Component Analysis (PCA) was the extraction method used under the IBM SPSS 19.0 system. The result of the Principal Component Analysis seemed somewhat reasonable in the absence of a clear idea of the nature of the distribution of airlines personnel interviewed in the study; that is, since we could not tell whether the data was generally normally distributed or significantly normal. The numbers of factors retained following the analysis were five including: supervision of staff performance; effect of good interpersonal relationship; effect of provision of working equipment/facilities; reward for excellence in performance and the need for credit on staff performance. The critical variables that motivates employees of the airlines is the provision of working equipment and facilities. This is closely followed by need for labour pressure group to protect the interest of the staff. The next prime motivator of the workforce is provision of adequate reward system for excellence in workers’ performance of their task. From the communalities recorded in the analysis, where it is shown that the two variables with the lowest values scored 0.610 and 0.654 respectively. One may therefore summarize that the analysis has unraveled the structure of the factors used to represent human resource management strategies.Item Open Access Passengers demand model for domestic airline in Nigeria: A case study of Airk Air(U. P., 2017) Ejem, E. A.; Ibe, C. C.; Okeudo, G. N.; Dike, D. N.; Ikeogu, C. C.; Igboanusi, C. C.In this paper, a passenger demand model for domestic was built. This model considers roles of airline service variables such as; service frequency, aircraft size, ticket price, flight distance, and number of airports in the route. It takes into account the influence of originating passengers in the metropolitan areas. The airport capacity, which has significant impact on service quality in airport and in the airline network, is considered. Researchers confirm importance of originating passengers, finds that, interestingly, airlines’ services in first flight leg are more important, and attracting passengers than those in the second flight leg. Based on study data, it was discovered that DIST, ORIG, DOMI and CAPA has positive individual elasticities of 0.027, 0.654, 0.558 and 1.137 with respect to passenger demand in airline route. This implies that 1% increase in each variable will increase passenger flow by 0.2%, 6.5%, 5.6% and 11.4% respectively in airline routes under study. These findings are helpful for airlines to understand effects of changing services, and also useful for us to quantify benefits of airport expansion projects.
