Extended models for TSALBP with ergonomic risk constraints

In this paper, we present an extension to the TSALB problem (Time and Space constrained Assembly Line Balancing) with ergonomic risk restrictions. This ergonomic risk is defined from the task durations and their categories regarding to the risk factor for the workers. A study is presented through a case linked to an engine assembly line in the Automobile industry, considering variable demand.

Solving a Mixed-Model Sequencing Problem with production mix restriction by Bounded Dynamic Programming

In this article, we propose a hybrid procedure based on bounded dynamic programming (BDP) assisted by linear programming to solve the mixed-model sequencing problem with workload minimization (MMSP-W) with serial workstations, free interruption of the operations and with production mix restrictions. We performed a computational experiment with 23 instances related to a case study of the Nissan powertrain plant located in Barcelona. The results of our proposal are compared with those obtained by the Gurobi solver and previous procedures. MSC:90C39, 90B35

Hybrid procedure based on Bounded Dynamic Programming and Linear Programming for solving a variant of the MMSP-W

In this paper, we propose a hybrid procedure based on Bounded Dynamic Programming (BDP) and linear programming to solve the Mixed-Model Sequencing Problem with Workload Minimization (MMSP-W), with serial workstations, free interruption of the operations and production mix restrictions. We performed a computational experiment with 225 instances from the literature. The results of our proposal are compared with those obtained through the Gurobi solver and previous procedures.
