Optimization of tasks in an operational production plan 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. To counterbalance fluctuations and inaccuracy of operational planning it is necessary to introduce the positive feed-back into the system in a form of registering of operations implementation.
