Abstract - Supply chain management is an essential feature of conducting any business operations This system manages a network of interconnected companies that are responsible for providing end users with product and service bundles It includes all raw material, work-in-process inventory, and finished goods movement and storage from point of origin to point of consumption It is primarily intended for the manufacturing industry, and it provides knowledge about product releases to the company's clients and distributors

Keywords: Java Servlet, Model-View-Controller, Web Applications

A INTRODUCTION

Ten years ago, the word “Supply chain” or “Supply chain management” rarely appeared in the work of managers They just use the terms “logistic” or “load” to describe the flow of goods However, in recent years, this term has become popular, even becoming a major that attracts many students from a myriad of Universities So, what is supply chain management? We can find various definitions in google but by common definition, Supply chain management is the coordination of production, inventory, location and transportation among departments in the supply chain to quickly and efficiently respond to the market need

To gain a specific understanding about the huge roles of supply chain management, our group decided to create a website “Supply chain management system” The system's primary goal is

to streamline contact between the organization's administrators, customers, and suppliers This project keeps track of details about the company's clients and distributors in relation to its product launch This will also keep track of sales and suppliers The website includes five main functions: Inventory management, Inventory management, Logistics and shipping status, Forecasting, Return management This report will provide the outline of the requirement, overview of the characteristics and constraints of the system

B MAIN CONTENT

This application is designed to run on any computer Java software must be installed on the client side computer The person who registers for the application has the ability to apply his registration form and then determine the conditions based on his classification This document plays a vital role in businesses that are the priorities of the Supply Chain Management Tool As a result, it is anticipated that the firm will communicate specifically with each of its clients when it comes to product details It satisfies a variety of customer specifications The system's primary goal is to automate coordination between the organization's management (Admin), customers, and dealers

I DEVELOPMENT

1 Model View Controller ( MVC)

In the project, to build the website, we follow MVC design pattern, Model DAO resource, JSP (Java Server Pages) works as View and Servlet works as Controller Frontend

we use React, Backend is Servlet and MySql to design databases Additionally, we use Data

Transfer Object Pattern (Entity, DTO, DAO) to transfer data between Client and Server

2 Analysis

Database is absolutely an integral part of software systems To fully utilize ER Diagram

in database engineering guarantees you to produce high-quality database design to use in database creation, management, and maintenance An ER model also provides a means for communication

3 Design

4.1 Database design & Design Pattern

Database design : Layered Architecture Style

In this setup, you have the presentation or GUI tier, the data layer, and the application logic tier

● The application logic tier The application logic tier is where all of the "thinking" takes place, and it knows what the application allows and what it can do, as well as making other decisions This logic tier also writes and reads data to and from the data tier

● The data tier All of the data used in your application is stored in the data tier This tier allows you to safely store data, perform transactions, and even browse through massive amounts of data in a matter of seconds.In data tier, the database is MySQL database

● The presentation tier The user interface is the presentation tier This is the interface through which the app user communicates This is where they input the necessary data This tier also serves as a conduit between the data and the user, relaying the user's various behaviors to the logic tier The presentation tier is the Web application that you see It's shown in a Web browser on your computer, and it includes CSS, JavaScript, and HTML codes that help you understand the Web application The presentation tier will show you boxes for username, password, and a submit button if you need to log in All of this will be passed on to the logic tier after you fill out and apply the form

● The logic tier will have the JSP, Java Servlets The logic tier would be run on a Web server

Design Pattern: Mediator Design Pattern

Mediator is a behavioral design pattern that allows you to reduce the chaos of object dependencies The pattern prevents the objects from communicating directly with each other, forcing them to collaborate only via a mediator entity

This project follows the Agile model and each module is independent to avoid tons of code repeats In the code base, the database layer should be reusable, models should be reusable

According to the Mediator pattern, you can stop all direct contact between the components you want to be independent of one another Instead, these components must work together via a specific mediator object, which guides calls to the relevant components As a result, instead of being linked to hundreds of colleagues, the components are only reliant on a single mediator class I create an auto table link class in code that is supported by the model classes To get the data from the table I, all I have to do is define the model class when doing database interaction

4.2 Backend Design

JDBC is a set of specifications that defines how a program written in java can communicate and interact with a database It provides a vehicle for the exchange of SQL

between java applications and databases Programs developed with Java and the JDBC are platform independent and vendor independent

Servlets and Java Server Pages are complementary APIs, both providing a means for generating dynamic Web content A servlet is a Java class implementing the javax.servlet.Servlet interface that runs within a Web or application server's servlet engine, servicing client requests forwarded to it through the server A Java Server Page is a slightly more complicated beast JSP pages contain a mixture of HTML, Java scripts (not to be confused with JavaScript), JSP elements, and JSP directives The elements in a Java Server Page will generally be compiled by the JSP engine into a servlet, but the JSP specification only requires that the JSP page execution entity follows the Servlet Protocol

4.3 Frontend Design and Customer Interface

The frontend server uses React for flexibility and maintenance due to its modular structure

JSP (Java Server Pages) technology allows designers to easily create Web content that has both static and dynamic components JSP technology projects all the dynamic capabilities

of Java Servlet technology but provides a more natural approach to creating static content CSS, HTML and Bootstrap libraries for responsive design were also used to improve user experience

JavaScript enables Web authors to write small scripts that execute on the users’ browsers rather than on the server An application that collects data from a form and then posts it to the server can validate the data for completeness and correctness, for example,

before sending it to the server This can greatly improve the performance of the browsing session because users don’t have to send data to the server until it has been verified as correct

To access the web application, we access http://localhost:5000/ While the page is being

loaded, the presentation server makes requests to the application server by fetching localhost:8080 using the node-fetch library to get data from MySQL database

Figure 6 - Supply Chain Management System Homepage access the web application by http://localhost:5000/

It is the management of flow of products and services with other functions

Figure 13 – Order Management

In this view the administrator can: Add a new product, Update or delete existing products, manage data for inventories, manage data, and Automatically get latest data

Figure 14 - Inventory Management

Some errors in product cause “FAILED” status The manager can change status from PENDING to SHIPPING so the order displayed in order management once upon

Figure 16 – Change Status in Return Management

5 Implementation

In this module Administrator can check the availability of the product, the new launched product information It also checks the delivery of product to the clients request and filters the products which are not being ordered by the clients

Whenever the Admin login into the system, it first checks the client requirements and then contacts the various dealers depending upon the requirements specified by the client

II Evaluation

1 Advantages

It will be easy for the user to become familiar with and competent in using the user interface on the first contact with because the website have friendly customer interface as well as view the web clearly Coupled with 5 main functions( Inventory management; order management, logistics and shopping status; forecasting; return management) , users will quickly achieve their objective through using the website

2 Limitations

Topic Supply chain management is a broad topic so we just focus on some main aspects Coupled with, this topic is hard to study, so it is time-consuming to plan, discuss, assign tasks and build this web

3 Future Improvement

Our project’s delivery dates and times are not stated, but they can be added as a future improvement We will complete this web for the manager in charge of all functions At any given time, only one report is produced We will make improvements to make it possible to generate more reports and maintain the daily schedule as part of the project's potential improvements Furthermore the authentications may also be obtained by the vendor during

C Conclusion

We have created this site with great potential and it can be easily integrated in the future The website will help customers save time and travel expenses, customers can easily order at home with just a few clicks Furthermore, our project is created with the aim of meeting the needs of the general consumer to the greatest extent possible We hope that you will see all the features and benefits that this website has to offer
