MRP Inventory System Mobile

I developed a mobile app that takes bill of material and the gross requirements of the end item along with the stock, scheduled receipt, arrival on week, lead time and lot sizing rule information of the subcomponents to create MRP records for all parts and components of the snow shovel.

Product Structure

Consider the product structure that belongs to a snow shovel. The demand and the inventory data provided below:

System Operation

There are 3 buttons in the application. These are "Order Item", "Reset Order" and "Update Inventory" buttons.

"Order Item" button

1. User enters the id of the item he wants to order in the "Item id" section.
2. The user writes down how many pieces he wants for the weeks he wants to order.
3. The user presses the "order item" button.
4. If the selected item exists in the system, the item entered as input is assigned as the current item. If there are no items in the system, the 1st stage will be returned.
5. Calculations for the entered item are returned.
6. Calculations are printed on the screen in tabular form.
7. Sub-item test is made for the current item, if there are subitems, calculations are made for the subitems and printed on the screen.

"Reset Order" button

After ordering the item, it deletes the tables printed on the screen.

"Update Inventory" button

When the button is pressed, you can see the current inventory status.

Saving data to inventory has been added with SharedPreferences.
