Most production environments face random, unexpected events such as machine failure, uncertain processing times, the arrival of new jobs, and cancellation jobs. For reduction undesirable side effects an disruption, initial schedule needs to be reformed partially or entirely. In this paper, a mathematical model is presented address integrated cell formation cellular rescheduling problems in manu...

Cellular Manufacturing System (CMS), an application of group technology philosophy, is a recent technological innovation that can be used to improve both productivity and flexibility in modern manufacturing environments (Signh, 93; Sarker and Xu, 1998). In practice, the essence of CMS is to decompose a manufacturing system into manageable autonomous subsystems (called manufacturing cells) so as...

Nowadays, in highly competitive global markets and constant pressure to reduce total costs, enterprises consider group technology and Supply Chain Management (SCM) accordingly and usually separately as the key elements for intra and inter facilities improvement. Simultaneous consideration of the elements of these two disciplines in an integrated design can result in higher efficiency and ...

In manufacturing systems, different types of disturbances influence system’s performance, cellular manufacturing has been proposed as an approach to cope with the uncertainty characteristic of customer driven markets. However, even cellular manufacturing systems are prone to the effects of varying demand patterns. In this study, the effects of some aspects related to demand variation such as th...

Reconfigurable Manufacturing Systems (RMS) bring new possibilities toward meeting demand fluctuations while, at the same time, challenges scheduling efficiency. This paper presents a novel approach that, for problem of RMS on multiple products, finds dynamic control policy via group deep reinforcement learning agents. These teamed agents, embedded with shared value decomposition network, aim mi...

This paper presents a new, bi-criteria mixed-integer programming model for scheduling cells and pieces within each cell in manufacturing cellular system. The objective of this is to minimize the makespan inter-cell movements simultaneously, while considering sequence-dependent setup times. In CMS design planning, three main steps must be considered, namely formation (i.e., piece families machin...
