Distribution of agricultural produce is undertaken to bridge the gap between production and consumption arising due to spatial separation between areas of surplus and deficit. An investigation of primal-dual links to spatial equilibrium model and integration of palm oil markets in Nigeria was carried out using transportation model. Two-stage sampling technique was used to collect data from 3 markets and 276 distributors. Data were analyzed using linear programing model. Average cost of transportation per mode was bus (N17,173), truck (N10,357) and lorry (N5,831) respectively. Total transportation cost of N347,809,600.6k was observed compared to a minimized objective cost of N142,536,800.30k produced by the program. Highest optimal allocation to the destination markets using the different mode of transportation were Port Harcourt–Lagos by lorry (103,200 MT), Owerri–Maiduguri by truck (21,200 MT) and Ondo–Lagos by bus (19,800 MT) respectively. Subsidized cost of public transport facilities will reduce high cost of transportation.

The poor quality of transportation infrastructure in Nigeria impacts negatively on the competitiveness of palm oil. This leads to increased inter-regional transportation cost, delayed time of arrival to the destination and lowered transaction efficiencies in the distribution chains. Primary and secondary data were used. Random sampling technique was used to collect data from 276 distributors in main palm oil markets. Data were analyzed using linear programming and Ravallion model at 0.05 a-level. Results of the data analyzes show that average cost of transporting palm oil from the production market to the consumption market was N5,831.9 per MT. Observed transportation cost was N60,724,830.5 while the optimal cost was N44,003,500.30 indicating a 38.0% reduction in total cost of transportation. Highest optimal allocations to the destination markets were Owerri-Jos (133,500 MT), Ondo-Lagos (107,200 MT) and Port Harcourt-Kano (82,000 MT) at minimum transportation cost of N5,750, N4000.7and N6500.0 per MT respectively. Two lag periods were identified signifying that it takes about 1-2 months for price information to spread across the markets by the model. Six of the 27 market pairs exhibited high short-run market integration for both lag periods with Port Harcourt-Abuja market pair indicating the highest (0.1 and 0.004). The lowest short-run market integration was recorded in Ondo-Minna market pair indicated by 1.4 and 17.4 respectively. Policies that will enhance redistribution of palm oil supply between producing and consuming regions should be pursued.

The study examined the factors influencing economic performance of palm oil production in Abak Local Government Area of Akwa-Ibom State, Nigeria. The study was based on primary data collected with the aid of pre-tested questionnaire from 120 respondents using multistage sampling technique in the study area. Descriptive statistics and multiple regression analysis were used for data analysis. Results revealed that majority (78%) of the palm oil producers were female with a mean age of about 50 years. The costs and returns analysis indicated that palm oil production was a profitable enterprise with a rate of return of 1.17. The result of the regression analysis revealed that age (p<0.05), education (p<0.01), membership of cooperative society (p<0.05), cost of equipment (p<0.05) and cost of labour were the significant factors influencing economic performance of palm oil producers in the study area. The major constraints faced by the producers were inadequate capital, lack of credit facilities, lack of access to improved inputs and technology, price fluctuation among others. The study recommended that, government, both at the federal and state levels should make credit facilities available and accessible to the palm oil producers at low interest rate in order to sustain and invigorate their economic performance.

This paper researching on vehicle collaboration distribution of TPL alliance, discussing the solution to the arrangement of vehicle routing problem which is base on “multi-deport” vehicle distribution of the triangle network. As for the key situation of vehicle distribution, clusters the supply and demand nodes into sliced area in order to constrain triangle distribution model and realize the triangle closed-loop route of vehicle distribution in both pickup and delivering. By comparing relative advantages of the traditional distribution model and the triangle distribution model on many code aspects; then stimulate the problem with improved ant-algorithm; finally analyzes the results of stimulation. The results imply that the triangle network of vehicle distribution can reduce unload ratio and the cost of transportation, can improve full-load ratio and can achieve the optimal allocation of transport resources.

Service Quality Dimensions

This study analysed cargo airline services and cargo delivery in Nigeria. The focus was on identifying the disparity between expected and perceived airline service quality on cargo delivery. This study was carried out in Lagos State, Nigeria. Random sampling technique was used to select 239 freight forwarders agents that operate in the Cargo Terminal of Muritatal Muhammed International Airport, Lagos State. SERVQUAL model and t-test were used to analyse the disparity between expectations and perceptions of airline service quality. SERVQUAL model average gap score is -0.126 which implies that customers are not satisfied with cargo airline service quality. Moreover, the findings revealed that there is a negative disparity between customer expectations and perceptions of airline service quality on air cargo delivery with Reliability having the lowest negative t-value of (-34.409), followed by Tangibles with a t-value of (-23.300), Responsiveness has a t-value of (-12.910), Assurance followed with t-value of (-13.572) while Empathy has a t-value of (-10.165). Conclusion is drawn that cargo airline customers' expectations about their service quality are more than they really perceived. Recommendation was made that cargo airline should make an assessment of service quality dimensions (Tangibles, Reliability, Responsiveness, Assurance and Empathy) and provide a means to improve upon them.

AbstractThis paper explores the goals, nature and results of government interventions into the rice and palm oil markets of Malyasia since independence. Its purpose is to compare the relatively successful way in which the government has promoted the palm oil industry with the failure of interventions in the rice market. The historical comparison of public efforts in these two industries points up the importance of setting consistent goals, of encouraging crops which match the natural resource endowment of the country, of having a private sector which is capable of responding to production incentives, and of letting supply and demand determine prices when designing a strategy of market intervention. Above all, it is important to distinguish programs of intervention based primarily on efficiency criteria from those which seek to perform social welfare (e.g. income support) and political (e.g. food security) functions as well.
