This is because of its inherent capacity of improving productivity and customer satisfaction in terms of prompt service delivery. The manual approach to the arrival to this decision has become laborious in recent time due to the growing complexity of production processes particularly in the small scale industry. Hence, this paper presents the CAE (Computer Aided Engineering) approach to arriving at PPC decision in a small scale bottled water industry in Nigeria. The paper shows software development for PPC in small scale bottled water industry using Visual Basic.6.0 2006 environment and Microsoft Office Access 2007 with mathematical models. Simulation of the developed system shows the vantage of software development in handling predominant manual engineering task such PPC in such industry. As a result, software development for handling various engineering tasks (process planning, quality assurance for example) for different small scale industry in Nigeria is highly recommended. This will not only improve productivity, but also create employment and increase the GDP (Gross Domestic Product) of such industry in the country.

Introduction Production is the process whereby an input (raw material) is transformed into an output (product). The process is value adding and the added value can measured by the difference in the value of the output compared to the input. The main objective of production is to produce a customer demanded goods and services efficiently and economically. One of the managerial responsibilities in any production industry is production planning. The control of the plan is to ensure compliance with the set plan through daily monitoring of the production towards the attainment of the set production quantity. It is reported that PPC (Production Planning and Control) can be referred to as coordinating system of the production operation. It function is to efficiently utilize the available material resources, people and facility in any enterprise through planning, coordinating and controlling the production activities that transform the raw material into finished products or components in most favourable manner [1]. Planning problem begins with a specification of customer demand that is to be met by the production plan. Control of production plan becomes inevitable due to the fact that production planning is potentially active and always remains in dynamic status as plans may have to be modified in agreement to changes in circumstances [2]. Practically, production planning presents propose daily plan for production activities within a time frame usually referred to as planning horizon. The control is the daily actual performance comparison and calculation of deviation from the proposed plan within the horizon. This deviation from the plan in terms of produced quantity shortfall is ploughed back into the demand for the remaining period of the horizon and a new plan is generated. PPC requires analytical skills and understanding of production process [1]. The complexity of modern day production industry as therefore made the manual approach mentally difficult. Hence, the introduction of the computer aided engineering approach become appropriate.
