Process Inventory Management in a Production Company

This paper analyses the economics of material management in the 7up Bottling Company, Benin for the duration (2011 – 2015) with a view of designing a process inventory. The specific objectives were to determine the level of efficiency and product improvement in material management, investigate whether the material management practice permit high stock turnover validation and to proffer useful suggestions on how to effectively manage the company materials. The variance analysis and Economic Order Quantity (EOQ) model were used to analyse the data collected. The results showed that the company spent a total of 118.8 million naira for production process and made a total sale of 395.84 million naira. This implies that the company optimises production by adopting the EOQ model into their production process and management. Based on these findings, the study recommends that optimal quantity and timing of material ordering in production process is a key to profit maximisation

Prospects of the Nigeria Brewery Industry

This study analyses the economics and determinants of a brewery industry (Guinness Nigeria Limited) with a view of establishing the future of breweries in Nigeria. The specific objectives were to estimate the factors influencing products production and determine the viability of products manufactured by the company. Multiple regression and the ordinary least square techniques were used to analyse the long-term (2006 - 2015) annual time series data observed for the study. The results showed that the major determinant of Stout, Harp and Malt production is demanded. As a significant input, it positively influences product production. The observed values of regression coefficients (R2) are 0.99349 (for Stout), 0.90981 (for Harp), and 0.99498 (for Malt), which indicates that they are reliable for determining the future of Guinness Nigeria Ltd. The results also showed that logarithm of demand for Stout production (LstoutD) of 13.5277, LharpD of 21.8439 and LmaltD of 12.2653 were projected respectively up to the year 2025, an indication that brewery production in the state is viable and that future is bright

Quality Maintenance of Production Equipment: A Case Study of Bendel Feeds and Mills, Ewu, Edo State

This paper analyses the quality maintenance in Bendel Feeds and Mills, Ewu, Edo State, with a view of designing a robust maintenance process and schedule to enhance production equipment in the company. The specific objectives were to determine the failure rate in the company production equipment, establish the appropriate maintenance process needed to reduce failure rate, investigate whether the current material handling methods and practices permit high maintenance turnover and to proffer useful suggestions and ideas on how to effectively maintain production equipment in the company. Data obtained were used to analyse the materials handling equipment failure rate, MTTR, MTBF, availability, failure mode and work station. The results showed that the failure rate is more in bucket elevator equipment than other materials handling equipment. It was observed that the plant organisational structure is area controlled instead of centre controlled organisation, which is one of the problems of the plant maintenance policy adopted by the company. Maintenance of materials handling equipment of the plant can be better achieved through modified planned preventive maintenance, condition base maintenance (predictive) and equipment inspection. This analysis will be of tremendous help to practicing maintenance engineering

Design and Development of Beans (Phaseolus Vulgaris) Shelling Machine

The design and construction of a beans shelling machine, using locally available materials is presented. A detailed design of the various machine components was done, and the appropriate engineering materials were selected for various parts of the machine. A working drawing, detailing the machine components was done for the shop floor fabrication of the machine. The results of the performance evaluation carried out, showed that a shelling efficiency of 81.3% was obtained. The machine has a capacity of 100kg/hr of unshelled beans and a production cost of forty-one thousand, one hundred and fifty naira (N41,150). Keywords: Beans, Shelling Machine, Efficiency, Vibration

Robust Stabilisation of Reformer Coupled Tanks

Diesel plays a significant role in the energy consumption in most developing countries. It serves as a source of power for the transportation, agricultural and industrial sectors. Diesel is one of the product of the petroleum, being utilised in all types of compression ignition engines as fuel. Hence, the need for reformer tank to manage proper waste is needed to avoid economical loss and environmental damage. The utilisation of reformer tanks in the management of waste energy is of economic and environmental advantage to the nation. This paper presents the use of feedback linearization and back-stepping methods to control the nonlinear reformers tanks in order to achieve robust control and stabilisation of the diesel. The model was transformed to a motion control model and the efficiency of the suggested algorithm was tested. The result showed that the back-stepping controller design is satisfactory not only for the tracking performance but also for the determination of the stability region
