Excel Spreadsheet for Tracking Stock Price with Buy and Sell Signals with Color Symbols Using Custom Formatting

Excel Spreadsheet for the Stock Market

Pallets are loaded from a fully Automated Handling System.
The Robot places the Items on the Pallet and the Automation System updates the Database.
Whith the use of Table Triggers (SQL code that fires when we have a Insert/Update/Delete event in the table).

Pallets Movement System

Production Weighing System

With use of Heursitic Algorithms the system is trying to find the best area match of Rolls (max rolls) on a Pallet.
The algorithm finds all possible solutions. And suggests for the Optimal solution.
Full parametrical with different:

- Material thickness (affects roll diameter)
- Core diameters (affects roll diameter)
- Role Length (affects roll diameter)
- Pallet types (different pallet sizes)

Orders Loading and Release in Flow Shops including Outsourcing Networks

January 2006IFIP International Federation for Information Processing 257:75-92

Purpose of this paper is to analyse and compare the behavior of workload control models in flow shops of both the MTO (Make-To-Order) and MTS (Make-To-Stock) classes. A simulation model has been built, where a manufacturing cell is loaded through an input control mechanism with shop orders coming from a pool. The pool itself is fed with planned orders coming from an MRP system.

A methodology and Simulation of Workload Control in Cellular Manufacturing

APMS’93

In this paper, a new approach of Workload Control of a Manufacturing Cell is presented. An effort is made to develop a model, using a computer simulation language, to extract conclusions about the application of workload control methodology in cellular manufacturing environment. The manufacturing cell is loaded with work orders using an input control mechanism 'the pool' that is also loaded by planned orders from an MRP system.
