MS Access with Visual Basic Tutoring

Alexandros won this contract as an access specialist because of an online challenge. Unfortunately, he already wanted 3/5 of the budget for the first small sub-task :-( That might have been ok. But his VBA code didn't work in Access DB. He couldn't handle my criticism and canceled the order instead of talking to me...

I was looking for someone to help me longterm with my Access DB and VBA. I had received many offers and decided to organize a small online challenge. The winner based on time and quality should get the contract. Alexandros was the only one who was willing to do this at short notice and has mastered the task with flying colors and thus won the main contract. I consider Alexandros to be completely capable and trustworthy.

Development of an IT Application for Online Statistical Surveys

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.
