Flexible manufacturing Systems are automated manufacturing systems which have job shop flexibility and flow shop efficiency. One of the major concerns in Flexible Manufacturing System (FMS) is the minimization of the total flow of material through the system. Facility layout design deals with the arrangement of machines, in order to minimise the total flow of parts in the system. The commonly u...

In pursuit of flexible and agile automation within the domain of discrete manufacturing, a paint-shop with its surrounding logistics and handling processes is under construction as a laboratory prototype application. Holonic Manufacturing is argued to be a promising strategic paradigm and architecture to use for a system characterized by flexible production logistics and control. This paper des...

During last decades, developing multi-objective evolutionary algorithms for optimization problems has found considerable attention. Flexible job shop scheduling problem, as an important scheduling optimization problem, has found this attention too. However, most of the multi-objective algorithms that are developed for this problem use nonprofessional approaches. In another words, most of them c...

This paper deals with the cyclic scheduling of flexible job-shop with time window constraints and resource capacity constraints. For time window constraints, the duration for processing products on machines and the duration for translating products from one machine to another by transfers are taken into account; for the resource capacity constraints, the confined operation space of machines and...

background: in children, inappropriate treatment of open femoral fractures may induce several complications. a few studies have compared the external fixator with flexible intramedullary nails in high-grade open femoral fractures of children. the present study aims at comparing results of these two treatment methods in open femoral fractures. methods: in this descriptive analytical study, 27 pa...

In the United States, right‐to‐work (RTW) laws impose open shop on labour unions. I test whether RTW affects frequency and outcomes of union representation petitions. Quasi‐experimental tests reveal no association between law volume certification petitions filed that fewer are withdrawn under RTW. Thus, unions do not appear to retreat from new member organizing law. Moreover, correlates with a ...
