In order to improve the loading/unloading operation efficiency of single-shuttle AS/RS under dynamic working conditions， a simulation optimization model was established for the job integrated optimization problem of AS/RS. The model considered the weight of goods and the frequency of entering and leaving the warehouse to divide the rack area. To minimize the running time of single-shuttle stacker in the instruction， a two-stage wolf pack algorithm was designed. The algorithm used the wolf pack algorithm to optimize the storage location assignment and job scheduling， and the solution processes reflected the mutual connection and feedback between the two optimization problems. The experimental results show that under different order sizes， the two-stage wolf pack algorithm may obtain satisfactory solutions and effectively shorten the operation time of AS/RS， compared with other optimization methods.

Focus on an information and part flow hybrid driven asynchronous serial production systems（HASPS） with a rework loop， the impacts of processing and information control parameters to the steady-state performance of a complex production system were analyzed with the consideration of random breakdown of manufacturing devices and information control devices. Based on the interactive relationship between part flows and information flows， the HASPS with a rework loop was split into various hybrid driven sub-assembly systems and sub-disassembly systems by overlapping decomposition approach. A forward- and backward recursive algorithm was proposed to estimate system steady-state throughput. Numerical experiments and acase for digital production systems of industrial sewing machines verified the efficiency of the recursive algorithm in identifying the bottlenecks and estimating the steady-state performance.
