App Inventory Management

App Inventory Management

The application is intended to create model for inventory management.. The models of inventory management can be of various kinds. With the present model are supported information for: Current stock, Ordering cost, Lead time (days), Holding cost per unit, Annual demand mean, Annual demand standard deviation and Service level Z. The structure of the data and algorithms are borrowed by MS Copilot.

Each of theses terms describes a different part of how an inventory system behaves. Together, they determine how much you should order, when you should order, and how expensive it is to hold or replenish stock. Understanding them clearly makes EOQ, ROP, and Monte Carlo simulation much easier to interpret.

The data for inventory elements of the app are stored in Data Base(DB) of the type SQLite with name inventory.db. The start screen of the app MainActivity include functions: Add Items Activity, Dashboard Activity and Dashboard Custom List Activity. Additionally through the menu items are included functions Copy DB, Import DB and Init DB. Copy DB copies the data base to a selected directory on the device , Import DB restores DB from old copy, and Init DB restores DB from example copy made by developers.

Add Items Activity

It has functions for creating the data of a new inventory element(button New) , edit selected element( ListView with inventory elements data: ID , Name, Current stock, saved in DB and calculated EOQ, ROP are showing in it( button Edit), delete selected element( button Delete), showing Dashbord with calculating data and simulated by MonteCarlo results. When creating or edining inventory element together with the data template you can show help for each feature. When editing or deleting entered data for an item, first select the item from this list and press the button to execute the corresponding function.

Dashboard Activity

Shows the result data for each inventory element in the list of consistent text.

Dashboard Custom List Activity

Shows the result data for each inventory elements in table. The data from the table can be printed( menu element Print) as file with the name AppInventoryManagementFile.txt The folder where to store this file are selected from activity Export DB/ Save file. From activity Export DB/ Save file may be executed feature for showing content of this file
