ABSTRACT:
The project shows how the statistical process control charts were capable of tracking the forecast values that were in control and out of control . Additionally, the project shows the benefits of tracking the differences of forecast and sales order to avoid customer order shortages or production write offs. Finally ,the study addresses the importance of statistical process control application & its benefits in other companies ,products . Leading manufacturers take a proactive approach to quality by incorporating tried and true SPC solutions into auditing applications as well as production. They evolve defect detection processes and after‐the‐fact analytical tools into standard practices that reduce variability. Applying SPC techniques to the line tightens the tolerance on variability, resulting in far more efficient raw material utilization, fewer out of spec parts, and less scrap and rework. As a consequence, the end product is of higher quality, customers are happier, costs are lower, and profits are up.

Keywords: Average or Mean (X-bar) , Range (R), Standard Deviation or Sigma (6), Process Spread (P.S.), Cp, Process Mean, Variance, Skew ness, Kurtosis.
Features
In statistical process control, one or more control variables of the observed characteristic are selected and determined by taking samples from the process at set time intervals if possible. These statistics are

    The objective of a process control system is to provide a statistical signal when assignable causes of variation are present “ if you can’t describe and measure it the you can’t control or improve it.” SPC a process used to monitor standards by taking measurements and corrective action as a product or service is being produced. Control chart a graphical presentation of process data over time. A process is said to be orperating in SC when only source of variation is common(natural) causes. The process must first be brought in statistical control by dectecting and elimination special(assignable) causes of variation. The objective of Process Control Sysytem is to provide a statistical signal when assignable causes of variation are present. Natural variation variability that affects every production process to some degree and is to be expected also known as common cause. Control charts for the mean x or x-bar and the range R are used to monitor processes that have variables (continuous dimensions). X-chart tells us whether changes have occurred in the central tendency(the mean) of a process. The R-chart values indicate that a gain or loss in dispersion has occurred. The theoretical foundation for x-charts is the central limit theorem which states that regardless of the distribution of the population of all parts or services, the distribution of x’s tends to follow a normal curve as the number of samples increases. 95.45 % +/- 2 std dev. 99.73% +/- 3 std dev. Attributes are typically classified as defective or nondefective. 2 attribute charts p-chart measure the percent defective in a sample and c-chart count the number of defects in a sample. Acceptance sampling method of measuring random samples of lots or batches of products against predetermined standards.…

    ¨Statistical process control (SPC) involves using statistical techniques to measure and analyze the variation in processes. Most often used for manufacturing processes, the intent of SPC is to monitor product quality and maintain processes to fixed targets. Statistical quality control refers to using statistical techniques for measuring and improving the quality of processes and includes SPC in addition to other techniques, such as sampling plans, experimental design, variation reduction, process capability analysis, and process improvement plans.¨(reliability.sandia.gov, Statistical Process Control)…

    Control limits help measure statistical differences easily for an individual (Godfrey, Stephens, Wadsworth, 2002). The control limits in the process will be 15 below the average amount it will take for the entire process. The average time was 55 minutes, so therefore the process should take 45 minutes or less to be efficient, and discover if the improvement actually helped the process. The standard deviation in the process will be five to ten; so it will be correct in the process.…
