Automation and flexibility are often mentioned as key concepts in modern production industry. To increase the level of flexibility, deterministic finite automata (DFA) can be used to model, specify and verify the production systems. Often, it is also desirable to optimize some production criteria, such as for example the cycle time of a manufacturing cell. In this paper, a method for automatic ...

The recent manufacturing environment is characterized as having diverse products due to mass customization, short production lead-time, and unstable customer demand. Today, the need for flexibility, quick responsiveness, and robustness to system uncertainties in production scheduling decisions has increased significantly. In traditional job shops, tooling is usually assumed as a fixed resource....

Assessing the quality of a weld in the steelmaking industry is a complex task. The level of complexity increases when the assessment is based on non-destructive tests. Skilled technicians are often required to make a decision based on automatic assessments of welds. Technicians consider the results of the automatic assessments and use their expert knowledge in order to make a final decision abo...

The simulation of the process planning is a decisive stage in the manufacturing process of a set of parts. This simulation is generally carried out by the calculation of the working dimensions (WD) according to the blueprint dimensions (BPD), to the means of production and to the machining process. The calculation and the generating of the working dimensions can be done by using different metho...

Purpose: Analysis is made of requirements posed by tasks of agents operating in the intelligent manufacturing systems and their resulting architecture is presented. Design/methodology/approach: Architecture of agent systems for industrial environment is presented, making it possible to generate the particular agents customised for the specific tasks, based on the automatic analysis of its requi...

1. Necessity of an Automatic Simulation System For the realization of today's miniaturization and low voltage drive of ULSIs, it has become much more important to understand and predict the effect of process variations on device performance. Predicting the quantitative effect of every process variation o n device characteristics has following advantages: In designing, required performance range...

Purpose: The aim of the current study was to investigate the effectiveness of schema therapy and mindfulness based cognitive therapy on the rate of using negative automatic thoughts in women with major depression in Mashhad. Participants were 36 depressed women clients, randomly selected and randomly designated to 3 groups (two experimental group and control group). Materials and method: This s...

Abrasive waterjet cutting nowadays represents cold precise, computer controlled shape cutting without any strain [1, 2]. These attributes pose this technology to the position of permanent use in the future, that represents excellent perspective for expansion in volume sectors, especially there, where the materials with excellent utility properties are used [3, 4]. The AWJ technology is, under e...

The integrated circuit (IC) manufacturing industry is one of the biggest output industries in this century. The 300mm wafer fabs is the major fab size of this industry. The automatic material handling system (AMHS) has become one of the most concerned issues among semiconductor manufacturers. The major lot delivery of 300mm fabs is used overhead hoist transport (OHT). The traffic jams are happe...
