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,...

The introduction of Cyber-Physical Systems, the implementation of machine learning, and the proposal of other technologies are some of the main features of Industry 4.0, which aims to change the way of production by introducing more flexibility and more autonomous decision-making by machines....

With the development and changes of industry and market demand, the personalized customization production mode with small batch and multiple batches has gradually become a new production mode. This makes production environment become more complex and dynamic. However, traditional production...

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...

The flexible job-shop scheduling problem (FJSP) is a typical mixed-integer linear programming problem, which plays an important role in operation research. A variable neighborhood search (VNS) enhance genetic algorithm (VNSeGA) is presented to minimize makespan of FJSP in this paper. In VNSeGA,...

With the continuous upgrading of industrial technology and information technology, consumers can deeply participate in the whole life cycle of products and realize customized production. These unprecedented changes have brought consumers and manufacturers closer together, resulting in the...

In this study, the problem of scheduling a set of jobs and one uncertain maintenance activity on a single machine, with the objective of minimizing the makespan is addressed. The maintenance activity has a given duration and must be executed within a given time window. Furthermore, duration and...

The problem of scheduling jobs on parallel machines (identical, uniform, or unrelated), under incompatibility relation modeled as a block graph, under the makespan optimality criterion, is considered in this paper. No two jobs that are in the relation (equivalently in the same block) may be...

Over recent years, a fairly large number of project scheduling problems have been focused on maximizing the Net Present Value (NPV) of cash flows during the project. From the contractor's point of view, cash inflows generally represent their revenues, and cash outflows are expenditures. In most...

A manufacturing company's production-related decision-making is to a large extent characterized by machine scheduling and support device operations management. All these industrial equipment types consume energy, often in the form of electricity. This electricity is more and more provided by...
