Constraint programming model for resource-constrained assembly line balancing problem

13th International Conference on Natural Computation, Fuzzy Systems and Knowledge Discovery (ICNC-FSKD) -- JUL 29-31, 2017 -- Guilin, PEOPLES R CHINAWOS: 000530043200044The literature studies assume that resources used to be perform the tasks are certain and homogenous in any assembly line. However, tasks may need to be processed by general resource requirements in real life. These general resources could be classified by usage of resources such as simple or multiple, alternative and concurrent. The problem which is related to assignment of the task to any workstation and assignment of resources needed by the task simultaneously is defined as resource-constrained assembly line balancing problems (RCALBPs). In this study, a multiobjective model with minimization of cycle time and resource usage for a given number of stations is modeled to solve the RCALBP for the first time. Alternative and general resource types for tasks and using more than two resource type requirements are also considered. A constraint programming model is developed and solved to find the optimal solutions of these problems. The proposed models are tested with sample scenarios to show the effectiveness of the model.IEEE, IEEE Circuits & Syst Soc, Guilin Univ Elect Technol, Hunan Univ, Guilin Univ Technol, Guilin Univ Aerosp Techno
