During the past half century, market competition has been very intense and production companies have been trying to find more efficient ways to manufacture their products. While during the period 1960 to 1970 manufacturing cost was the primary concern, later it was followed by product quality and delivery speed. New strategies had to be formulated by companies to adapt to the environment in whi...

With the growing use of flexible manufacturing systems (FMSs), it became more important to optimize them. Scheduling is one critical problems in FMS optimization. This study presents a new application multi-criterion decision-making (MCDM) methods for scheduling automated guided vehicles (AGVs). The problem addressed this research refers situation, which several orders from different job statio...

Symmetric mathematical programming is used to analyze the optimality of balancing workloads t~ maximize the expected production in a single-serve~closed queuing network model of a flexible manufacturing system (FMS). In particular, using generalized concavity we prove that, even though the production function is not concave, balancing workloads maximizes the expected production in certain types...

The paper presents a model of designing of machine layout in flexible manufacturing system (FMS). Evolutionary computation, particularly genetic algorithms (GAs) proved to be successful in search of optimal solution for this type of problems. To achieve high productivity in a flexible manufacturing system (FMS), an efficient layout arrangement and material flow path design are important due to ...

This paper describes multi-objective evolutionary optimization of process planning in flexible manufacturing systems (FMSs). FMS can be described as an integrated manufacturing system consisting of machines, computers, robots, and automated guided vehicles (AGVs). While FMSs give great advantages through the flexibility, FMSs pose complex problems on multi-objective process planning. An evoluti...

Scheduling in a manufacturing system is currently a research hotspot. This paper proposes a flexible, single-operation, serial-batch scheduling problem with mold constraints that arise from injection molding production. In such a scheduling problem, three decision problems exist: product batch splitting, sequencing, and resource selection. A divide-and-conquer framework is introduced to solve t...

Society, POM-2001, March 30-April2, 2001, Orlando Fl. Batch Sizes in Push Manufacturing Operations Planning, Scheduling and Control Track Abstract: Isn't Push manufacturing dead and 1 the best batch size? Many manufacturing companies still use a Push system and they do so with batches of more than 1! They need to produce with little risk of late completion. To reflect this need, a new measureme...

In this study, we have done the scheduling of FMS using fuzzy logic approach. It has been applied by many researchers to various manufacturing problems. With the help of fuzzy logic, we can incorporate both numerical and linguistic variables. The advantage of fuzzy logic is that it has the ability to consider multiple criteria and can deal with uncertain or incomplete information. Scheduling of...
