Abstract As markets demand targeted products for highly differentiated use cases, the number of variants in production increases, whilst volume per variant decreases. Different product result differences work content on workstation level which cause takt time losses and a poor utilization. In this context, matrix-structured systems with neither temporal nor spacial linkage emerged to reduce eff...

Scheduling for job shop is very important in both fields of production management and combinatorial op-timization. However, it is quite difficult to achieve an optimal solution to this problem with traditional opti-mization approaches owing to the high computational complexity. The combination of several optimization criteria induces additional complexity and new problems. In this paper, we pro...

this paper deals with a bi-objective hybrid no-wait flowshop scheduling problem minimizing the makespan and total weighted tardiness, in which we consider transportation times between stages. obtaining an optimal solution for this type of complex, large-sized problem in reasonable computational time by using traditional approaches and optimization tools is extremely difficult. this paper presen...

the aim of a multi-mode resource-constrained project scheduling problem (mrcpsp) is to assign resource(s) with the restricted capacity to an execution mode of activities by considering relationship constraints, to achieve pre-determined objective(s). these goals vary with managers or decision makers of any organization who should determine suitable objective(s) considering organization strategi...

During material handling processes, automated guided vehicles (AGVs) pose a path conflict problem. To solve this problem, we proposed multi-objective scheduling model based on total driving distance and waiting time, used the A* planning algorithm to search shortest of AGV. By using speed control strategy, were able detect overlap time. Additionally, adopted an efficient MapReduce framework imp...

We present a bi-objective parallel machine scheduling problem with and job sequence dependent setup times, the additional consideration of resources needed during setups. The availability such is limited. This models many practical situations where times imply, for example, cleaning and/or reconfiguration productive equipment. These setups are performed by personnel, who course limited in numbe...

The optimization of bus scheduling is a key method to improve service. So, the purpose this paper address regional public transportation dispatching problem, while taking into account association between departure time buses and waiting passengers. A bi-objective model for established minimize total cost passengers maximize comprehensive service rate buses. Moreover, NSGA-II algorithm with adap...
