    Capacity Planning and System Utilization in the Management of Queues in Selected Banking Hall in Ilorin Metropolis
    (College of Management Sciences, Al-Hikmah University, Ilorin, Nigeria., 2012-06) Mustapha, A. M.; Aremu, M. A.; Fakokunde, T. O.
    Capacity planning and system utilization have become critical issues because most banks operate their facilities at a rate less than installed capacity. Experts have traced this development to deficiency in capacity planning and system utilization in the management of queues in the banking halls. The main objective of this study is to determine the relative adequacy of capacity planning and system utilization in the management of queues in the banking hall. The study utilized arrival and departure data of customers into the bank through direct observation. Inter-arrival period of 15 minutes was used. The cost function of the bank was also used to determine whether the present system can be improved upon or not. Findings revealed that there were more inflow of customers than expected at a given time interval resulting in pressure on the existing capacity. The paper recommends that management should make a contingency plan to respond to any unusual crowd that may arise during those periods when queues are noticed to be more..

    Modeling Finite and Infinite Queuing Processes
    (Cosmic Journals India, 2013) Mustapha, A. M.; Oyeyemi, G. M.
    This paper considers an infinite queue where the arrival of future customers is not affected by the numbers of customers already on the queue and a finite queue where customers attempting to enter when people are already present are denied entry, or blocked. In particular, we analyze the problem based on the assumption that one or more elements of the queuing system can be expressed only in probabilistic terms. To study the effect of blocking arriving customers, we first establish some stochastic comparison of the performance measure formulas that permit us to compare the different operating policies. These comparisons show that in M/M/I queuing model, there is an infinite room to hold arrivals waiting for service. M/M/K/F queuing model has a limited capacity.

    Simulating Demand for Rice in Owode Market, Offa L.G.A Kwara State
    (Pakistan Society for Business and Management Research, 2013) Mustapha, A. M.; Oyeyemi, G. M.
    Estimating the optimal weekly demand (purchase) of rice in any market is one of the fundamental tasks in determining how much product should be purchased weekly and the expected value. Rice, one of the foods consumed which used to be a food of the highly privileged one before but occasionally consumed during important festivals by the less privileged ones some years ago has become a stable food that is consumed by almost all the households in Nigeria today. Its consumption is so high to the extent that the locally produced ones cannot meet the demand of the teeming population. Reports have it that the country spent a lot of its hard earned foreign reserves to import rice in order to meet the increasing domestic demands for it. Nigeria consumes 5.4 million MT of rice annually with #600 billions of which 1.6 Million MTS are imported. Nigeria is the largest importation of rice in the world, buying at least 2 million metric tones per year from exporting countries like China and Thailand, yet Nigeria fertile land and rich agro climate conditions could easily produce rice to feed the entire country and generate surplus for the region (USAID). According to This Day News Paper of 17th December, 2012, the Federal Government disclosed that $150 billion will be spent to meet Nigerians annual demand by 2050. The amount spent has been so colossal and alarming that there is a need to stimulate the demand for rice over certain periods of time to confirm the government assertion and claims, hence, this study. Specifically, the objectives of this paper are to generate a demand pattern for 25 weeks in Owode market, Offa Local Government, Kwara State, and estimate optimal weekly demand for rice and determine the expected value. The analytical tool used in this study is Monte-Carlo simulation model. Findings revealed that on the average, 523.6 bags of rice were demanded per week, and the expected value puts at 521.9 bags. The paper recommends and concludes that drastic and urgent action should be taken by the government to encourage locally produced rice in order to safe the country from spending so much foreign reserves on importation of rice.
