Purpose: Assembly Line Balancing (ALB) is critical to manufacturing efficiency and productivity. It involves assigning tasks to workstations to optimise performance while satisfying task priority and cycle time constraints. The Simple ALBP (SALBP) is a simplified version of the general problem...

Long-term throughput, as a key performance indicator of a stochastic flow line, is affected by numerous parameters describing the features of the flow line, such as processing time and buffer size. Fast and accurate evaluation methods for a given set of values for those parameters are a...

This study presents an integrated supply chain network with suppliers, manufacturers, assemblers, and customers. The proposed model considers a U-shaped assembly line with three sustainability objective functions. We consider assumptions considering different types of raw materials, multiple...

A classic production line for mixed models with a fixed cycle time is transformed into a flow shop by removing the time restrictions at the work stations. In the new production line, the Heijunka concept of Just in Time manufacturing is applied, imposing on the sequences of products that they...

A typical Assembly Line Balancing (ALB) Problem aims to optimize the mass production process by assigning the tasks to stations. To deal with the high product variety and short product life cycles, robots are utilized in many production lines. Humans and collaborative robots share the same...

The Sequence-dependent Cost-oriented Assembly Line Balancing (SDCALB) problem is a challenging optimization problem that belongs to the NP-hard class. To solve this problem, a position based mathematical model is formulated and then the Pure Bender's Decomposition (PBD) algorithm is proposed....

In this work, we consider a scheduling problem faced by a company involved in the production of off-road vehicles using a three-level assembly process, subject to precedence, machines, and resource constraints. This problem has multiple characteristics shared with other scheduling problems,...

Rapid product changes and fierce global competition force companies to react quickly to market changes associated with dynamic capacity. This paper investigates how to design and reconfigure configurations of the single-product scalable reconfigurable robotic assembly line (RAL) over multiple...

Despite the various industrial applications integrating inbound transportation, production, and inventory, only single-product studies have been conducted addressing the related production and inventory routing problems simultaneously. To meet the optimization requirements of many-to-one...

Companies must establish a profitable system to ensure their survival. Due to increased competition, businesses must now make sacrifices on the sales price of the product or service produced in order to remain competitive. Station opening costs play a significant role in assembly line...

Understanding how skilled workers interact with assistance systems in manufacturing and how they experience the factory environment is fundamental to modeling human interaction and optimizing the processes correctly. This paper investigates humans’ behaviors and perceived experiences while...

The geographical dispersion of collaborative factories may provide the cost-saving potential for manufacturers and lead them to easier fit the global markets. On the other hand, in such networks of factories, coordination is very important for the just-in-time delivery of orders. This study...

Products cannot be produced as perfect as nominal values due to errors in manufacturing and assembly processes. These complex errors eventually affect the function and performance of the finished products. This paper deals with how to minimize the overall errors when assembling each part which...

This paper analyses the production planning for the multi mixed-model assembly lines (MMMAL) for building elements prefabrication. Industrialised housebuilding (IHB) prefabrication plants struggle with increasing the productivity of existing prefabrication equipment through the application of...

Currently, advanced production systems enable fast and flexible capacity planning and production scheduling connected to the existing enterprise resource planning (ERP) system. In this paper, a comprehensive optimization problem is developed for a composite of an assembly line balancing problem...

It is important to increase the efficiency of assembly lines to use production resources correctly and effectively. There are many studies in the literature for this purpose. For assembly lines, the most important production resource is the worker, and workers are affected by ergonomic factors...

Rosling (1989), one of the classic papers in inventory theory, studies an assembly system with stochastic demand. Under the condition that the initial state of the system possesses a certain property referred to as "long-run balance," the optimal policy is characterized as a balanced echelon...

This article focuses on the Mixed-Model Assembly Line Balancing single-target problem of type 2 with single-sided linear assembly line configurations, which is common in the industrial environment of small and medium-sized enterprises (SMEs). The main objective is to achieve Algorithmic...

In MMP-elections (Mixed Member Proportional representation), a QP-ballot contains a first-vote for party Q’s candidate in a single-seat constituency and a second-vote for a list of candidates from party P in one common tally. In split ballots P≠Q. Traditional accounting (e.g. in Bundestag...
