Meeting customer demands requires a high degree of flexibility as well as abilities to reconfigure operations for new demands. Based on literature review, various types of flexibilities are presented with a view to clarify their correspondence. This paper highlighted the merits, demerits and applications of RMS and FMS. Different technique of RMS and FMS are overviewed. The recent researches in...

In the recent years, batch process optimization has made significant advances. The efforts that went into the development of ISA-S88/IEC 61512 batch control standard has helped us in this direction. However, in today’s highly competitive environment, optimization of individual manufacturing plants is not enough. In order to maximize the return on investments, control engineers must turn their a...

In order to solve the flexible job shop scheduling problem with variable batches, we propose an improved multi-objective optimization algorithm, which combines idea of inverse scheduling. First, a batches model is formulated. Second, batch algorithm in size adjusted by dynamic feedback adjusting method. Moreover, increase diversity population, two methods are developed. One threshold control ne...

This paper presents industrial experience with a resource-constrained batch process scheduling program. The batch process representation is loosely based on the ISA S88 batch process standard. This representation allows the import of batch process information from other software, e.g. batch process simulators. The scheduling algorithm is a non-optimization approach that proceeds in two steps. F...

To better understand future needs in manufacturing and their enabling technologies, a survey of experts in manufacturing has been conducted. The survey instrument (i.e., questionnaire) tries to assess the experience to date with the use of flexible manufacturing systems (FMS) and to examine the potential roles and enabling technologies for reconfigurable manufacturing systems (RMS). The results...

Starting from a comparative analysis of used algorithms in fabrication processes scheduling, this paper presents the advantages and efficient uses of genetic algorithms. In the case of technological processes of machining a flexible batch of marks, the structure of a scheduling optimization algorithm is presented, by the mean of different technical and economical priority rules. The paper outli...

The manufacturing of microsystems such as micromotors and micropumps among other examples is a very important emerging market. One big challenge in microproduction is mass customization, that is, the automated production of a large variety of products that are highly adapted to special customer needs in small batch sizes. These requirements call for a highly flexible manufacturing system. This ...

The production planning problem of flexible manufacturing system (FMS) concerns with decisions that have to be made before an FMS begins to produce parts according to a given production plan during an upcoming planning horizon. The main aspect of production planning deals with machine loading problem in which selection of a subset of jobs to be manufactured and assignment of their operations to...

Deadlock-free operation of flexible manufacturing systems (FMSs) is an important goal of manufacturing systems control research. In this work, we develop the criteria that real-time FMS deadlock-handling strategies must satisfy. These criteria are based on a digraph representation of the FMS state space. Control policies for deadlock-free operation are characterized as partitioning cuts on this...
