This paper proposes a dynamic modeling of transportation systems in semiconductor manufacturing. Utilizing our modeling method, we consider an optimal scheduling problem of AGV (automatic guided vehicle) system transfer problem, which is to control the AGV congestion on the junctions of the transportation road in this paper. The problem is recast as an ILP (Integer Linear Programming) problem within...
This paper presents a method to solve the optimal scheduling problem of Automated Guided Vehicles (AGVs). The problem is formulated into an integer programming problem by focusing a summation of idling time when an AGV does not operate any dispatching commands of transportation. However, there remains undecided constants exist in some constraints. Therefore, we propose a multistep algorithm to solve...
