In this paper, we describe PLUTO, an chemical Plant scheduling expert, system building Tool. PLUTO provides a framework to build scheduling systems for daily operation schedule of the facilities and personnel involved in the manufacturing process. PLUTO is exclusively designed for pipe connected plants with severe sanitary conditions, such as manufacturing of medical supplies, chemical and food products. Scheduling problems in these domains are difficult to formalize and solve with a general problem solver, as the conditions lead to complex constraints among tasks, facilities, personnel and materials. Scheduling systems built on PLUTO is able to generate schedules in a considerably short amount of time, by computing in a combination of heuristic search and constraint propagation and reducing the search space. In one such problem we have been able to reduce one third of the scheduling cost.
