Multiple Project Portfolio Scheduling Subject to Mass Customized Service

Declarative framework enabling to determine conditions as well as to develop a decision making software supporting small and medium size enterprises aimed at unique, multi project-like and mass customized oriented production is discussed. The set of unique production orders grouped into portfolio orders is considered. To each production order treated as an activity network common shared resources operation times of which are known in advance are allotted. The problem concerns of scheduling of a newly inserted projects portfolio subject to constraints imposed by a multi-project environment The answer sought is: Whether a given portfolio can be completed within assumed time period in a manufacturing system in hand? The goal is to provide a declarative model enabling to state a constraint satisfaction problem aimed at multi project-like and mass customized oriented production scheduling. The attached calculation example illustrates the computational efficiency of the proposed solution.
