A Review Analytical Quality Control and Methodology in Internal Quality Contr...ijtsrd
Analysis quality control, often abbreviated in AQC, refers to all those processes and processes designed to ensure that the results of laboratory analysis are consistent, comparable, accurate and within certain limits of accuracy. The components submitted to the analysis laboratory must be accurately described to avoid misinterpretations, assumptions, or incorrect results. Quality data and quantity produced in the laboratory may be used for decision making. In the chemical sense, quantitative analysis refers to the quantitative or concentration of an element or chemical compound in a matrix that differs in element or compound. Fields such as industry, pharmaceuticals, and law enforcement can use AQC. The first important factor in setting up the internal quality control IQC of a clinical laboratory evaluation process is to select the appropriate IQC procedure to be used, i.e. to select the mathematical method or control rules, and the number of control measures, depending on quality. required for methodological evaluation and performance. Then the appropriate IQC process should be used correctly. This review focuses on strategies for planning and implementing IQC processes to improve IQC quality. The plural editing process is defined which can be used with image tools such as dynamic work or critical graphs and performance specification charts. Finally, a comprehensive QC strategy is developed to reduce costs and increase quality. The standard IQC implementation strategy is recommended to use a three phase design where the first phase provides high error detection, the second phase low false rejection and the third phase defines the duration of the analytical implementation, using an algorithm that integrates data from normal patient data.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

Abstract
In this report we will discuss that how statistics use in industrial processes or chemical
companies or even in our daily life, and what are the application and benefits of is. So,
because of that we need a good quality control system that component in the production of
good clothes. we will learn that the quality means money.
5. APPLIED OF STATISTICS IN CHEMICAL INDUSTRY QUALITY CONTROL 2
1. Introduction
This science can assist us in comprehending our history and making future forecasts.
We may use statistics to examine data in many domains to track evolving trends, then utilize
the results to develop conclusions and projections. Statistics entails a significant volume of
data. Or, to put it another way, the collaborative study of massive data gathering, processing,
interpretation, and display. The study of successful data collecting, data summarization, and
inference making procedures in a framework that clearly recognizes the reality of nonnegligible
variance in real-world processes and measurements is known as statistics. For more effective
information flow management, statistical approaches are used in chemical research for data
gathering and analysis of chemical substances. [1]
The current market is quite competitive. As a result, producers must ensure that their
products are of consistent quality. They must inspect each and every product they manufacture
in order to assure and maintain consistent quality. However, due to the huge volume of
manufacturing, this is not practical. As a result, they must understand statistical quality control
in order to ensure constant and uniform product quality. [2]
SQC assesses the quality of premium goods and services using a variety of statistical
approaches. Walter A. Shewhart proposed the core principles for statistical quality control in
1924, and since then, the field of SQC has been built on the work of many scholars, quality
control philosophers, and statisticians. [3]

2. What is the Statistics?
2.1 Definitions and Concepts
Statistics is the study of data, which includes characterizing data attributes and deriving
inferences about a population based on data from a sample. A crucial idea in inferential
statistics is the separation between a population and its parameters and a sample and its
statistics. The two primary disciplines of statistics are descriptive statistics and inferential
statistics. Descriptive statistics are used to characterize a group of people. [4]
2.1.1 What is a descriptive statistic
The goal of descriptive statistics is to analyze data without reaching any conclusions.
The data is presented in the form of tables and graphs. The characteristics of the data are
discussed in simple words. Accidents, commodity price, business, earnings, sicknesses, sports
data, and demographic information are just a few of the events that are handled. [5]
Fig. 2: Descriptive statistics and inferential statistics are the two main areas of statistics.
7. APPLIED OF STATISTICS IN CHEMICAL INDUSTRY QUALITY CONTROL 4
2.1.2 What is an inferential statistic
The goal of inferential statistics is to come up with a population claim. In most cases,
however, because surveying the whole population is practically impossible, a sample, or a
small data set taken from the population, is used. [5]
2.1.3 Example of descriptive and inferential statistics:
Let's say we wish to describe the exam results for a class of 30 pupils. We keep track
of all of the test results, compute summary statistics, and create graphics. Here is the CSV data
file: [6]
Fig. 4: These results indicate that the mean score of this class is 79.18. The scores range from
66.21 to 96.53, and the distribution is symmetrically centered around the mean. A score of at
least 70 on the test is acceptable. The data show that 86.7% of the students have acceptable scores.
Fig. 3: Process of the Inferential Statistics.
8. APPLIED OF STATISTICS IN CHEMICAL INDUSTRY QUALITY CONTROL 5
2.1.4 Example of inferential statistics
For this example, assume we did our research on test results for a particular class, as I
described in the descriptive statistics section. For the identical test, we'd like to do inferential
statistics research. Assume it's a statewide standardized test. I can show you how applying the
same test with the objective of making conclusions about a population impacts the way we
perform the study and the findings we report. [6]
3. What is the Statistical Quality Control (SQC)?
3.1 Overview
Statistical Quality Control is the use of statistical methods in the monitoring and
maintaining of the quality of products and services. When a choice must be made to accept or
reject a set of parts or products based on the quality observed in a sample, acceptance sampling
is one approach that may be employed. A second approach, known as statistical process control,
employs control charts to assess if a process should be continued or altered to attain the target
quality. [7]
3.2 Typical Workflow for Performing Statistical Quality Control (SQC)
The procedure for many statistical quality control methodologies is the same. For
instance, fine-tuning the filling operations for food, drinks, and cosmetics, as well as evaluating
the weight fluctuation in medicinal tablets (uniformity of dosage units). The maker must decide
the proper sampling quantity and frequency based on the criticality of the application. [8]
Fig. 5: Typical Pathway of SQC Process
9. APPLIED OF STATISTICS IN CHEMICAL INDUSTRY QUALITY CONTROL 6
Here are the steps to follow:
1. Select a pre-defined number of specimens from the production batch.
2. Weigh each item individually.
3. Calculate the statistical values and compare them with the predefined tolerances.
4. If within tolerance, the batch is released.
5. If out-of-tolerance, repeat the sampling and testing procedures.
6. If out-of-tolerance again, corrective measures must be taken.
7. Print results and statistics. [8]
3.3 Statistical Quality Control Techniques in chemical industries
The techniques of the control product & process quality involve:
3.3.1 Statistical Process Control
Statistical process control (SPC): is defined as the use of statistical techniques to
control a process or production method. SPC tools and methods can aid in the monitoring of
process behavior, the discovery of internal system faults, and the resolution of production
problems. Statistical process control and statistical quality control are often used

Here are 4 steps to develop a quality control technique:
a. Set your quality standards.
b. Decide which quality standards to focus on.
c. Create operational processes to deliver quality.
d. Review your results. [9]

3.3.2 Statistical Product Control
Controlling the quality of a product through careful examination and sampling
inspection programs is referred to as product control. Product Control seeks to ensure that a
specific level of quality is provided to customers. It makes an effort to verify that the offered
product does not contain a big number of faulty products. As a result, it is concerned with the
categorization of raw materials, semi-finished items, and final goods as acceptable or
rejectable. [10]

3.4 Principles of Applied Statistics
Because of the wide range of applications, it is difficult to offer a straightforward
summary of the essential concepts of applied statistics. Statistical data analysis is not a highly
specialized topic of study. The following principles as the most important:
1. Formulating and explaining specific research questions relevant to the subject
2. Creating solutions that provide a secure answer and open up new possibilities.
3. Development of efficient and reliable measurement procedures
4. Development of analytical methods with suitable software following the primary research
problem
5. Effective presentation and visualization of conclusions
6. Structured analysis to facilitate their interpretation in terms of subjects and their
relationship to the knowledge base of the field.
The main goal of applied statistics is to develop suitable concepts and methods that will
help in solving the tasks listed above. [11]

3.5 How the Chemicals Industries Can Use Statistics
Stan Higgins, a chemical industry pioneer, is aware of the projections and sees potential
for analytics to add value. Higgins, the former CEO of the North East of England Process
Industry Cluster, is now a non-executive director of Industrial Technology Systems and a
senior consultant to Tradable, a waste management and speciality chemical firm, and JMP, a
statistical analysis software supplier. He was made an Officer of the Order of the British Empire
in January 2018 for his efforts to promote the UK's chemical process manufacturing industry.

3.6 Application of Statistics In the chemical industry (chemical engineering)
Applied statistics is the foundation of data analysis, and it entails examining data to
assist define and identify organizational requirements. Applied statistics may now be found in
a variety of sectors, including medical, information technology, engineering, finance,
marketing, accounting, and business. [11]
3.7 Statistical Process Control Applied in the Chemical and Food Industry
The theoretical foundations of Statistical Process Control and the unit operations of
industrial processes are the focus of the theoretical foundations. In the process industry,
statistics tries to develop probabilistic and statistical techniques for data analysis and
interpretation from a collection of elements known as industrial statistics, which aids in the
control of industrial processes. This is how we employ measures of central tendency in
industrial processes for data management and interpretation, and statistical tools for process
control, particularly control charts, for decision-making process management. Certain
statistical methodologies govern the statistical management of industrial process data. [13]

publishes a report with oil and gas statistics on a regular basis. Data can be downloaded
dating back to 1965. One of the biggest oil firms, BP, publishes a report with oil and gas
statistics on a regular basis. Data can be downloaded dating back to 1965.
• Energy Statistics United Nations Statistics Division (UNSD) External: It collects and
disseminates international energy statistics in its flagship product, the Energy Statistics
Yearbook, which includes core data as well as aggregated tables, energy balances, and

power profiles. A link to the Energy Statistics Database, which covers the years 1950 to
2016, is also available on this page.
• EIA International: The Energy Information Administration of the United States
Department of Energy provides a country-by-country energy situation summary, as well as
global oil market and environmental data on energy production and use.

4. Conclusion
In this report we talked about the statistics generally and its techniques which very
useful in our applications in the industrial processes, So, by applying statistical process control
methods to the analysis of adverse events, we have showed how this allows us to determine if
a process is stable, whether an intervention is required, and if quality improvement efforts have
the desired effect.
