Arranging tasks of the laser cutter using the dynamic classification in conditions of unit and small batch production

In conditions of unit and small batch production a very important role is played by time of product availability for the customer. Despite using modern management techniques setup time still play an important role in the production cycle time. In the examined companies the relation between rearmament times to processing times is still high. The above researches inspired the author to prepare the method of setup times’ reduction through proper arrangement of tasks in the operational production plan. Optimization of the daily production plans is based on two-level division of scheduling and arranging tasks. The method was validated in conditions of the production practice for unit and small batch manufacturing. An example of arranging tasks for the laser cutter was given. The presented method is one of elements of the computer aided expert system for SME.
