The combined application of quality function deployment and pareto analysis for hotel services improvement
(Inderscience Enterprise Limited, 2008) Oke, S. A.; Ofiabulu, C. E.; Banjo, A. A.; Akanbi, O. G.; Oyawale, F. A.
This paper discusses the combined application of Quality Function Deployment (QFD) and Pareto Analysis (PA) to hotel services. This paper improves the current quality management practices in a case study hotel. This results into increased customer patronage and improved hotel profit margin. PA is applied as a prioritisation tool for the purpose of financial investment decision. The study may be applicable to other hotels. It could also significantly affect the goodwill of the organisation as well as its profit margin. This paper is new, in that it appears to be the first application of Pareto cum QFD principles in hotel services, and a new way of prioritisation and quality improvement in hotels systems
Mathematical modelling of lead assimilation by printing press operators in a poor indoor air quality environment
(Inderscience Enterprise Limited, 2008) Oke, S. A.; Ahmed, A. O.; Akanbi, O. G.; Oyawale, F. A.; Ofiabulu, C. E.
Most printing presses in developing countries are located in buildings with inadequate natural and mechanical ventilation such that the press operators work for major hours in poor indoor air quality buildings, which expose them to a wide range of health hazards such as lead poisoning. Understanding how poor air quality affects the operator's body system is studied using a methodology involving the principle of diffusion and the law of mass action. A hypothetical press in Nigeria is used as a case study to illustrate the workability of the model which may be of value to health inspectors to printing presses.
Mathematical modelling of the traffic congestion problem at a University campus
(2008-04) Oke, S. A.; Lofinmakin, O. O.; Salau, T. A. O.; Akanbi, O. G.; Ofiabulu, C. E.
"The traffic situation at many university campuses in developing countries has been a source of concern to both the school authority and the campus populace. This may be largely due to the increasing enrolment level for university admissions since most employers are certificate-biased instead of skill rewarding. The roads are often congested during the day thereby causing inconveniences to everyone. During the ""peak period"" when vehicular traffic is beyond what the road can contain conveniently, traffic jams occur, which accounts for a great amount of time wastage by commuters. This paper deals with the traffic congestion problem in a university in a developing country. The approach employs mathematical modeling to solve the problem. The principles of flow in fluid mechanics are interpreted at a macro level to the flow of traffic. The model describes the traffic situation, explains the causes and periods of congestion, and proffers a solution to the problem. "
Occupational lead exposure in printing presses: an analytical approach
(Akamai University, 2008) Oke, S. A.; Phillips, T. E; Kolawole, A.; Ofiabulu, C. E.; Adeyeye, D. A.
Lead absorption poses a great threat to the health of workers in printing presses where commercial publishing is done. A case example is the commercial printing operations in Lagos, Nigeria. Since regular exposure to lead dusts could result in lead poisoning, complications that could cause death of victims, monitoring and controlling lead absorption of operators is essential for the maintenance of workers’ health and for the avoidance of the risk of incurring heavy losses due to litigation. The purpose of this paper is to model the process, rate, and quantity of lead absorption in operators of printing presses. Measurements of lead absorption are made and compared to standards in individuals for control purposes. Two approaches are used. The first shows the risk of being poisoned by lead. The second approach relates lead poisoning to the rates of intake of lead into the body and its elimination out of the body. This model viewed the absorption of lead as a cycle and applied the continuity equation to this cycle.
