ABSTRACT
Logistics Supply Management System is movement of products from production area to warehouse. Warehouse is the way through which one can manage all these features easily and effectively. So it is necessary to manage all the warehouses which can hold products.
To develop an automated system that keeps the track of various products, articles present in the warehouse with a standard communication system. It is developed for a complete solution that is GUI based user-friendly system where even layman can use the system. A warehouse can store various products grouped under various category wise and it delivers the products according to the order. For the warehouse there is warehouse in-charge who is responsible for all process done at the warehouse.
The administrator controls all the warehouses and he has rights to perform any modification concern with any warehouse that are located all over the country. These entire warehouses are access by their warehouse-id. The warehouse administrator requests to the main authority to add new warehouse. There is a minimum stock level in each warehouse. If the product ordered by the customer is above the stock available than warehouse in-charge does not process the order and it is unavailable. If stock is available as per the demand than status of order appears in following state pending/process/delivered.

UTL has country wide presence to provide its customers timely & personalized services. UTL also has overseas presence is selected countries.
Need of Warehouse
Not every warehouse needs a WMS. Certainly any warehouse could benefit from some of the functionality but is the benefit great enough to justify the initial and ongoing costs associated with WMS. Warehouse Management Systems are big, complex, data intensive, and applications. They tend to require a lot of initial setup, a lot of system resources to run, and a lot of ongoing data management to continue to run. That’s right, you need to "manage" your warehouse "management" system. Often times, large operations will end up creating a new are department with the sole responsibility of managing the WMS
SOFTWARE REQUIREMENT SPECIFICATION
Software requirement specification (SRS) is a technical specification of requirements for the software product. SRS represents an overview of products, features and summaries the processing environments for development operation and maintenance of the product. The goal of the requirement specification phase is to produce the software specification document also called requirement document
External Interface Requirements
This system can be used very friendly, because any end user can use this software and get on his way very easily provided he must have some basic knowledge of the computer system and how to operate the system. Since every thing that will be provided will be fully graphically interfaced we can get step by step process with full details about what the process will do, so that the user can get used to it very well.
DESIGN
The purpose of the design phase is to plan a solution of the problem specified by the requirement of the problem specified by the requirement document. This phase is the first step in moving from the problem domain to the solution domain. In other words, starting with what is needed, design takes us towards how to satisfy the needs. The design of system is the most critical factor affecting the quality of the software and has major impact on testing and maintenance. The output of this phase is the design document
Logical and Output Design
The logical design of an information system is analogous to an engineering blue print of an automobile. It shows the major features and how they are related to one another. The detailed specification for the new system was drawn on the basis of user’s requirement data. The outputs inputs and databases are designed in this phase.
Output design is one of the most important features of the information system. When the output is not of good quality the user will be averse to use the newly designed system and may not use the system. There are many types of output, all of which can be either highly useful or can be critical to the users, depending on the manner and degree to which they are used.
Outputs from computer system are required primarily to communicate the results of processing to users, They are also used to provide a permanent hard copy of these results for later consultation. Various types of outputs required can be listed as below:
7.3 Table Design
A relational database consists of collection of attributes, each of which is assigned a unique name. A row in a table represents a relationship among a set of values. Since a table is a set of such relationships, there is a close correspondence between the concept of the table and the mathematical concept of relation .The global relational database is to generate a set of relations, which allows sorting information without redundancy and also allows us to store and retrieve information with ease.
IMPLEMENTATION
Once the design is complete, most of the major decisions about the system have been made. The goal of coding phase is to translate the design of the system into code in a given programming language. For a given design, the aim in this phase is to implement the design in the best possible manner.
The coding phase affects both testing and maintenance profoundly. A well-written code can reduce the testing and maintenance effort. Since the testing and maintenance costs of software are much higher than the coding cost, the goal of coding should be to reduce the testing and maintenance effort. Hence, during coding the focus should be on developing programs that are easy to read and understand, and not simply on developing programs that are easy to write. An important concept that helps the understandability of programs is structured programming.
TESTING
Testing is the major quality control that can be used during software development. Its basic function is to detect the errors in the software. During requirement analysis and design, the output is a document that is usually textual and non-executable. After the coding phase, computer program is available that can be executed for testing purposes. This implies that testing not only has to uncover errors introduced during coding, but also errors introduced during previous phases. Thus the goal of the testing is to uncover requirement, design and coding errors in the program.
An elaborate testing of data is prepared and the system is tested using that test date. Errors noted and corrections made during the testing. The corrections are also noted for future use. The users are trained to operate the developed system. Both hardware and software securities are made to run the developed system successfully in future.
System testing is the stage of implementation, which is aimed at ensuring that the system works accurately before live operation commences. Testing is vital to the success of any system. System testing makes a logical assumption that if all the parts of the system are correct, the goal will be successfully achieved.
CONCLUSION
In the past, the employees of the Warehouse have been associated with performing organizational function, such as order tracking, stock maintenance and products category management in accordance with policies that have been established in conjunction with organization.
The project deals with various operations and transactions that are carried out in the different levels of Logistics Supply Management System. Waterfall model is adopted for the development of the project
The developed system is user friendly and the changes can be made easily as and when required. Hence the system can be maintained successfully without much rework.
The Logistics supply management System thus developed provides highly coordinated and collaborative means for managing the sales and inventory activities in the organization. It serves, as a gateway for the accurate tracking of customer needs. It helps to track the project execution between the organizations. The features incorporated in the system such as
