A Distributed Order Promise and Planning System for the Virtual Enterprise

Abstract

This paper describes an «Order Promise» system to support decision making in the planning processes of Virtual Enterprises, viewed as networks of different units, namely plants, logistic centres and storage facilities. The system aims at improving customer due date calculation, and is intended to be a multi-site planning tool to co-ordinate local activities across the Virtual Enterprise network. It is based on the use of aggregate information and on a set of local rough capacity models. This work is part of a broader project with a particular focus on the microelectronics industry. Companies of this industry are a good example of Virtual Enterprises, where a quick response to the customers needs and to unpredictable changes in production conditions is considered a major factor for success.
