Abstract
The manufacturing industry undoubtedly has immeasurable impart on countries
worldwide. It has opened up business opportunities, create jobs, and improved
quality of life. It thus improves the socio-economic development of nations.
For instance, in 2012, the manufacturing industry contributed $1.87 trillion to
the united states’ economy. This was 11.9% of the united United States’ total
GDP(Gross Domestic Product). In the same way, in Ghana, it accounted for
27.6% of GDP in 2011. The pivotal role of the manufacturing industry to the
global economy is therefore not in doubt. The main objectives of this study
among others were to establish a good production schedule that will satisfy future
demand for the manufacturing industry, determine how to optimize a production
scheduling using transportation model and establish schedule formulation and
analyze using MATLAB software. The study modeled the production problem as
a transportation problem which involve determine how to optimally transport
goods.In a balanced transportation problem, the supply must be equal to
the demand. The initial basic feasible solution is found using the Vogel’s
Approximation Method and to iterate to optimality, the Modified Distribution
Method (MODI) is used. A twelve month data on production capacity at
Everpure Ghana Limited is collected for the study. The methods used have
proven appropriate in obtaining the optimum schedule. From the result, it is
clear that efficient scheduling could reduce production and inventory cost whilst
satisfying customer demand.
