Abstract:  To solve a scheduling problem of manufacturing cells with robot restricted processing (RRP), a scheduling strategy based on time constraints was proposed. Firstly, a nonfree robotic process was formally described by introducing novel concepts of internal and external residencies and fundamental period. A mathematical programming model considering characteristics of the nonfree robotic process, resources and residency constraints was established to minimize the average manufacturing cycle time. To optimize robotarm movements, a tabu circulatory time point searching algorithm was constructed.Finally, analysis of simulation experiments was implemented. Results indicate that the proposed algorithm is valid and feasible.

Key words:  robot restricted processing, manufacturing cells, residency constraint, time constraints, scheduling algorithm
