Robust Data Mapping Spreadsheet Developmentriptionstantial prowess in mapping data fields across multiple applications. The job will entail constructing

Alex is in Greece, while I'm based in the U.S. He has strong English communication skills was always available when we needed to speak. He is methodical, timely and very detail oriented. He built relationship tables across my apps as well as schemas for each application. The goal of all of this was to help me understand how our data manifest itself across various systems with an eye to building a method to manage master data in the future. I'm very happy with the outcome.

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...

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.
