Computer Science Project Material with Source Code Included


This research work was on automated price adjustment system, a case study of NTEPS supermarket, Ikot Ekpene. Supermarket managers are constantly in the business of buying and re-selling. However, the challenge remains that it takes time to manually compute and adjust the price of the item such that they will still make profit. Usually, this is determined from the cost price of the product. To facilitate the easy adjustment of the price of products sold in the supermarket, an automated system is needed to carry out the computation. The result can be saved to a database so that it can be confirmed whenever sales is to be made and also aiding easy adjustment of the price of items in the supermarket. The programming language used is Visual BASIC 6.0.

1.0 Introduction

The phenomenon of price adjustment is central in economics for several reasons. First, at the microeconomic level, since price adjustment is considered the main market clearing mechanism, whether prices adjust or not can have important implications for the efficiency of resulting allocations. Therefore, having a better understanding of the price change process can provide insights on issues like: how rigid are prices of individual products; how fast are costs passed-through onto prices; how long it takes prices to adjust to changes in market conditions such as changes in supply and demand, etc. Second, at the managerial level of an individual business, pricing and price adjustment play a critical role as it determines the bottom line profitability. For example, questions such as: how to adjust prices of individual products in response to temporary cost increases, how to adjust prices to competitors’ price changes, how to adjust prices of sale and non-sale items, how frequently to change prices, etc., are all questions pricing managers and retail sellers face on a daily basis. Third, there are variety of markets (e.g. different types of auction markets, non-auction markets such as markets with posted prices, etc.), and understanding the specific characteristics of these institutions may help us better understand and predict the outcomes observed at these markets. Given the importance of the price adjustment mechanism, it is not surprising that the issue has received considerable theoretical as well as empirical attention.

1.1 Theoretical Background

The introduction of computerized technology into the retail environment over the past two decades has resulted in new opportunities for retailer managers. For example, demand based management uses statistical models to predict consumer price response using historical information. The most prevalent type of information in retail markets is transaction data collected using optical bar code scanners which track every item purchased by a consumer at the point-of-sale. This data could potentially contain a wealth of information about how consumers respond to price and promotions. A price adjustment management system is a computerized system that aids in adjusting the price of products based on different variables such as cost price, transportation, taxes and commissions on products and competitors prices. This is done such that an optimal price is ascertained that still brings about a certain percentage of profit.

Most supermarket chains carry thousands of items in different categories, operate scores of stores, constantly adjust prices on a weekly basis due to changes in demand, supply, and competition, and may manage wholesale and retail operations. Price adjustment systems are meant to help managers make decisions, but they also serve to help automate decision making. Pricing specialists agree that businesses should price products based on value. Yet, many companies set prices based on the cost of their product (Ulaga, 2001; Hinterhuber, 2008). Alternatively, they set prices based on the prices of competing products, without fully accounting for the worth of performance differences between their product and the reference products.

In a research study aimed at identifying specific obstacles that prevent companies from implementing value-based pricing strategies Hinterhuber (2008) found that the number one obstacle was the ability to conduct an accurate value assessment. One respondent commented that his business team just did not have the tools to attach a financial value to their differentiated product.

1.2 Statement of Problem

Many supermarket owners do not have an effective method of adjusting price tags such that they increase their revenue and attract customers. There are many competitors in the market place and this influences the level of patronage especially if they are good in managing prices. In addition, the situation of charging higher than normal may also reduce demand and consequently bring about loss. This situation brings about the need for a price adjustment software system that can enable the adjustment of price of each product such that there is no loss or excess profit and also to provide avenue for updating price of items.

1.3 Aim and Objectives of the Study

The aim of the study is to develop an automated price adjustment system for supermarket. The following are the specific objectives:

  1. To develop an automated price adjustment system that can aid in the adjustment of prices of products.
  2. To develop a system that will allow the easy storage, retrieval and updating of prices of each registered product.
  3. To develop a system that will replace the manual way of managing prices of products
  4. To implement a system that the database can be queried easily.

1.4 Scope of the Study

This study covers automated price adjustment system for supermarket, a case study of NTEPS supermarket.

1.5 Significance of the Study

The significance of the study is that it will provide solution to the problem of adjusting price of products in NTEPS supermarket, it will serve as a management information system for super market owners. The study will also serve as a useful reference material to other researchers seeking information on the subject.

Summary, Conclusion and Recommendation

5.0 Introduction

This chapter presents the summary, conclusion, constraints of the study and offers useful recommendations.

5.1 Constraints of the Study

In carrying out the research work, some challenges were faced that limited the study such as:


The time given for the completion of the research work was too short hence the researcher had speed up the research work to meet up and this has an impact on the study.

Limited Materials:

Few materials were found pertaining to the research area and this limited the bulk of the literature review.


The high cost of textbooks, internet browsing and transportation to different libraries to gather materials stood as a constraint to the research work.

5.2 Summary

A price adjustment system is an automated system that facilitates the easy adjustment of price of products in a store or supermarket such that it will be easy to confirm the price of any registered product. It is easier than the manual way of printing price tag stickers and placing them on each product.

5.3 Conclusion

A price adjustment system is a very important system. It will aid easy management of the price of products and eliminate the process involved in manually adjusting the price of products.

5.4 Recommendation

  1. It is recommended that price adjustment software be implemented in supermarkets.
  2. Computer programmers should be contracted or employed to develop and manage a price adjustment system.
  3. More research should be encouraged and conducted in the area of price adjustment management system
