“…By utilizing domain properties, the authors presented an exact algorithm and a hybrid genetic metaheuristic. Zhou and Peng 11 addressed a combined routing and loading problem of a single machine in an assembly system. The schedule was to specify the destination station and part quantity within each delivery for minimizing line-side inventories.…”

With increasing product customization, just-in-time part replenishment has become a significant scheduling problem in the automobile assembly system. This paper investigates a new unrelated parallel machine scheduling problem of an assembly line, where machines are employed to deliver material boxes from an in-house warehouse to workstations. The schedule is to appropriately specify the assignment and sequence of material boxes on each machine for minimizing line-side inventories under no stock-out constraints. By taking advantages of domain properties, an exact algorithm is developed to cope up with small-scale instances. In terms of real-world scale instances, a hybrid teaching–learning-based optimization metaheuristic is established by integrating teaching–learning-based optimization with a beam search technique. Experimental results indicate that the scheduling algorithms are effective and efficient in solving the proposed unrelated parallel machine scheduling.

“…The authors mentioned that expensive line shutdowns represent a cause of this type of issue. In another case, Zhou and Peng [6] mentioned that the mixed-model assembly lines are extensively adopted in the current automobile production to satisfy the ongoing customization, however, material shortages are not allowed, as it would be extremely expensive due to the production line shutdowns. Finally, Zhao et al [7] presented a case study of delay-time-based preventive maintenance (PM) modelling for a production plant system in a steel mill.…”

“…Specifically, production line balancing is a traditional production strategy that helps decrease bottlenecks. As for shutdowns, they may be responsible for production losses [4] and increasing costs [5,6], especially when they occur unexpectedly and affect subsequent operations [14]. In particular, according to Hossen et al [15], idling and major stoppages and breakdown losses account for 89.3% of total stoppage losses.…”

This paper reports a case study using a standardization process for increasing efficiency and a better optimization of resources in a printing company with 150 operators having manual and mechanical tasks in the box assembly department along with four production lines. The current capacity is 350 boxes per day, while the demand is 650 units, where the company is expected to pay large sums for overtime. Using work standardization, studying worker movements, timing, and workstations redesign, the main goal was to increase the efficiency and productivity indexes. After applying those tools, the inefficient movements in operators decreased from 230 to 78, eliminating 66% of the unnecessary movements, as well as the standard time in a workstation decreased from 244 to 199 s (18.44%) per each assembled box, and the production rate increased by 63.2%, that is, 229 units per assembly line a day, where overtime was reduced to zero.

“…Apparel companies hope that materials can be distributed in a timely manner and reduce distribution costs, thereby improving production efficiency, and increasing corporate profits. Just-in-time distribution aims to accurately deliver materials to the required workstations at the right time and in the right way [12]. Therefore, the material distribution route and personnel should be reasonably planned to achieve on-time distribution for the purpose of high efficiency of material distribution.…”

Low-carbon production has become one of the top management objectives for every industry. In garment manufacturing, the material distribution process always generates high carbon emissions. In order to reduce carbon emissions and the number of operators to meet enterprises’ requirements to control the cost of production and protect the environment, the paths of material distribution were analyzed to find the optimal solution. In this paper, the model of material distribution to obtain minimum carbon emissions and vehicles (operators) was established to optimize the multi-target management in three different production lines (multi-line, U-shape two-line, and U-shape three-line), while the workstations were organized in three ways: in the order of processes, in the type of machines, and in the components of garment. The NSGA-II algorithm (non-dominated sorting genetic algorithm-II) was applied to obtain the results of this model. The feasibility of the model and algorithm was verified by the practice of men’s shirts manufacture. It could be found that material distribution of multi-line layout produced the least carbon emissions when the machines were arranged in the group of type.
