Manual Assembly Line Balancing Problem with Constraint COVID 19: (SALBCOVID19P)

The COVID-19 pandemic has had an extraordinary impact on global supply networks, particularly at the level of the manufacturing system. In this context, a new conceptual framework of assembly line balancing problem called SALBCOVID19P is presented in this paper. The whole product manufacturing workload is distributed among the stations throughout the manufacturing line in an ALBP. Previous research has concentrated on finding efficient and quick solutions for simple assembly line balancing problems (SALBP) and its numerous extensions. Several real-life applications and the necessity to solve exact practical difficulties drive each extension have occurred in the literature. In this article, a new extension of SALBP-1 with constraints related to the COVID 19 pandemic is focused. A mathematical model for Simple Assembly Line Problem Type 1 (SALBP-1) is exhibit with proposed constraints; workstations and workers. The new model of SALBP-1 assumes that each workstation has a minimum length and it exists a minimum distance between two operators. This new extension has been applied to an industrial case.
