A shorter version of this paper is being submitted to a journal.

We describe an emerging problem in manufacturing and its potential solution. The problem deals with the optimi-

zation of manufacturing supply networks, as opposed to the optimization of individual company manufacturing

facilities. The opportunity for cost savings is great, but the need to preserve confidentiality of each company?s data

presents a major impediment. Just-Enough-Information (JEI) is a new paradigm for production scheduling, based

on exchange of minimal proprietary data among companies. We describe a specific new algorithm to implement

JEI, based on exchange of Demand-Availability-Order (DAO) data. Evidence from simulation studies indicates

that this methodology is highly promising. Practical application depends on generalizing DAO and on complement-

ing it with a broad range of related systems, including real time coarse capacity management. The paper also

addresses these comprehensive requirements
