In this paper, a new mathematical model for the problem of job scheduling in virtual manufacturing cells (VMC) is presented to minimizing the completion time of all jobs. Sequence dependent setup times of machines is considered and lot-streaming is possible. In Virtual manufactur
a knowledge-based nsga-ii approach for scheduling in virtual manufacturing cells
this paper considers the job scheduling problem in virtual manufacturing cells (vmcs) with the goal of minimizing two objectives namely, makespan and total travelling distance. to solve this problem two algorithms are proposed: traditional non-dominated sorting genetic algorithm

Virtual Manufacturing Cell Formation Problem (vmcfp) in a Distributed Layout
There are essentially two ways to implement a Cellular Manufacturing System (CMS): physical and logical. In the first case, the machines are laid out in the floor space in dedicated manufacturing cells to exploit flow shop efficiency in processing part families, whereas in the se
Modeling Agile Manufacturing Cell using Object-Oriented Timed Petri net
An Object-Oriented Timed Petri-net (OOTPN) is proposed for modeling agile manufacturing cell (AMC). It consists of four phases: (1) grouping manufacturing resources into classes; (2) constructing general OOTPN block for each manufacturing resource class; (3) defining joint transi
Dynamic construction of virtual manufacturing cell considering workload balancing and machine failure
Machine is the key element in manufacturing system. failure will lead to order delivery delay and production cost rise. Aiming at random disturbance of equipment failure, a dynamic non-linear programming model virtual cell (VMC) established, which aims minimize cost, logistics tr
Possibilities of Ga in Optimization of Manufacturing Cell Formation
Optimization of manufacturing cell formation includes a whole virtual cell formation procedure and has NP-hard complexity. In the last decades, evolutionary algorithms have been widely applied to real-world optimization including to manufacturing cell formation problems. Genetic
Using CORBA to integrate manufacturing cells to a virtual enterprise
It is critical in today’s enterprises that manufacturing facilities are not isolated from design, planning, and other business activities and that information flows easily and bidirectionally between these activities. It is also important and cost-effective that COTS (commercial-
Manufacturing Cell Monitoring Process
This paper describes all the manufacturing cell monitoring process particularities, and its several features. It is also done a brief presentation of the data structure used to monitor the manufacturing cell status, and it is explained its achievement and its philosophy by a comp
Remote Robot Vision Control of a Flexible Manufacturing Cell
In a robotized flexible manufacturing cell, robot (-vision) controllers are masters over local workstations or cells, because robot manipulators connect two important material flows: the processing flow and the transportation flow. One solution to integrate these two flows with o
