Accordingly, the product should be compatible with the standard specifications within manufacturing stages to ensure acceptable quality. This research paper focuses on creating a system that monitors and records daily readings of cement physical tests at quality laboratories of cement factory and accordingly the control charts for each test were established. The importance of control charts for the variables lies in the expression of the system status (inside or outside the control limits); normally the points which are located outside the borders indicate that the system is out of control. But in some cases, the points are within the control limits but took an abnormal distribution. First, the system determines the style of pattern type, analyzes and then finds out the expected causes and suggests the solutions. The system was tested by inserting different records in different intervals of time; the results obtained were reasonable and had explained the effectiveness of the system. Keywords—Quality control; Control charts; patterns; cement laboratory. I. INTRODUCTION Recently, the River Nile State had witnessed a great leap in cement industry due to the fact that all production elements were available; raw materials (lime stone), which is available in most areas extending from Atbara to Abu Hammad[1]. Moreover, the availability of transport means (paved roads and railway tracks) linking production sites with national markets and ports of export, in addition to the availability of power sources and skilled labors [2]. Based on the above-mentioned reasons, the policy of supply and demand overshadows the local and regional market, making these companies at a big challenge to obtain the trust and the customer satisfaction[3]. Due to an increasing competition in products, consumers have become more critical in choosing products[4]. The quality of products has become more important. Statistical process control (SPC) is usually used to improve the quality of products and reduce rework and scrap so that the quality expectation can be attained. II. PROBLEM STATEMENT All the industries and institutions are keen to optimize the profit, and to be friendly with environment[5]. This will help these companies to keep its position and status within the market, such process will be maintained by developing and promoting the manufacturing systems as well as applying the total quality control principles[6][7]. Control charts are the most popular charts widely used in industry to detect abnormal process behavior[8]. The most typical form of control charts consists of a central line and two control limits representing the specifications of the product and the variant range limits[9]. This provides a useful method for monitoring variations in the product manufacturing process[10]. However, these control charts do not provide pattern-related information because they focus only on the latest plotted data points. There are five cement factories in River Nile State; all these factories are highly recommending improving their quality control system (mainly the physics lab) to be within the present international market competition. The process is applied through monitoring and documenting the results of different trails, analysis and decision making. III. THE OBJECTIVES The purpose of this research is to develop a quality control system of cement manufacturing using software technique, which is aiming to achieve the following objectives:- To record daily results for various physical tests. To draw control charts for variables (average, X), (range, R) for any period of time required. To find different patterns, then analyze and identify corrective action accordingly for each pattern. To Display the results of all tests at any time and obtain respective reports. IV. METHODOLOGY General information about the system, which includes machines, production stages, and sequence of operations etc, were gathered. Historical data of previous physical test results were collected, and the causes of poor quality were analyzed. Computer program created by using Visual Basic language will be used to control the quality and to evaluate and indicate the subgroup pattern and its analysis.
