One of the most critical pillars of Industry 4.0 (I4.0) is Additive Manufacturing (AM) or 3D Printing technology. This transformative technology has garnered substantial attention due to its capacity to streamline processes, save time, and enhance product quality. Simultaneously, environmental concerns are mounting, with the growing accumulation of...

Conventional parallel cooling channels introduce some challenges that would reduce cooling channel performance. So, presenting novel ideas is to improve the cooling channel performance and determine which parameters play a vital role in this flow field. In this study, the thermal performance of a conventional polymer fuel cell (PEM) parallel coolin...

This paper deals with optimizing the multi-door cross-docking scheduling problem for incoming and outgoing trucks. Contrary to previous studies, it first considers the simultaneous effects of learning and deteriorating on loading and unloading the jobs. A mixed-integer linear programming (MILP) model is developed for this problem, in which the basi...

ABS T R A C T Nowadays, one of the major goals of the distribution environment is to reduce lead times and inventories. Cross-docking is a logistics technique which removes the storage and picking up the functions of a warehouse. The term cross-docking refers to moving products directly from incoming to outgoing trailers with little or no storage i...

This paper investigates the effect of inflation and time value of money on an economic production quantity (EPQ) model in the single product system while the shortage of inventory is not allowed and production of defective parts during the production process and also setup time for reworking have been considered that can be non-zero. Studies show t...

This article considers a three-stage assembly flowshop scheduling problem minimizing the weighted sum of mean completion time and makespan with sequence-dependent setup times at the first stage and blocking times between each stage. To tackle such an NP-hard, two meta-heuristic algorithms are presented. The novelty of our approach is to develop a v...

This paper presents a new mathematical model for a two-stage assembly flowshop scheduling problem that minimizes the mean tardiness and earliness penalties. This problem is an extension of the assembly flow shop problem with simultaneous operations in the first stage and a single assembly operation in the second stage. The problem is known to be NP...

An assembly line is a flow-oriented production system in which the productive units performing the operations, referred to as stations, are aligned in a serial manner. The simple assembly line balancing problem (SALBP) is a fundamental version of the general problem which has attracted attention of researchers and practitioners of operations resear...

This paper considers a three-stage assembly flowshop scheduling problem with sequence-dependent setup times at the first stage and blocking times between each stage in such a way that the weighted mean completion time and makespan are minimized. Obtaining an optimal solution for this type of complex, large-sized problem in reasonable computational...

Over the past three decades considerable amount of research work has been reported in the literature of Group Technology (GT). Cellular Manufacturing System-an important application of Group Technology (GT) - has been recognized as an effective way to enhance the productivity in a factory. Cellular manufacturing is one of the most powerful manageme...
