To solve the real-time material delivery problems from the warehouse to workstations for the mixed model automotive assembly line in accordance with the production cycle, the dynamic material delivery method based on internet of things has been developed. The material flow and production characteristic of automotive assembly was analyzed in order to feed material properly & timely. The monitoring...
In this paper we study the possibility to use a transverse flux linear generator (TFG) because transverse flux technology presents the highest force density per volume index among the iron based electrical machines. This paper is organized as follows an introduction to describe “state of the art”of WEC's and TFG, in the Section II we find a summary description of the marine condition of the chosen...
Additive Manufacturing (AM) has a profound impact on the mass customization of consumer products. To take advantage of this new manufacturing resource we need to incorporate AM into existing design methodologies. In this paper, we address this need by proposing an AM resource process model for product family design. The proposed model captures the ability of AM to produce arbitrary complex structures...
To solving the real-time material delivery problems from the warehouse to workstations of the mixed model automotive assembly line in accordance with the production cycle. The material flow of automotive assembly, type of material and the production characteristic were analyzed in order to feed material timely & properly. The material real-time delivery system based on field bus has been developed...
This article demonstrates the ability of on-line optimization of cone crushers, specifically maximization of the total throughput of the crusher by adjusting the eccentric speed (ω). The on-line optimization was based on the Extremum-Seeking Control (ESC) approach, which is advantageous when optimizing systems with unknown time varying characteristics. Two types of gradient based approaches are tested...
In this paper, an electronic components inventory model with fuzzy multi-parameters is considered. Economic order quantity (EOQ) is developed for optimal order quantity with all parameters assumed to be exact or crisp. Actually these parameters are not precise while varying over a range. In such case fuzzy set theory is applied to electronic components inventory planning and control problems. With...
This paper attempts to highlight shortcomings in the concept of sustainability and ways to make the concept more workable by presenting the development of an Environmental Management Information System (EMIS) as a combination of discrete event simulation and ecological material flow analysis for production processes. The motivation behind the focus on simulation techniques on one hand and on production...
On one hand, the integration of ecological industry chain in mining area is affected by technology development level, market demand, industrial policy and the use of products, by-products and wastes. On the other hand, it is also limited by the optimal production scale, the inflows and outflows of the resources of industry units. Therefore, through the integration of optimal production scale of industry...
Evaluation and selection of green sustainable development (GSD) strategies is a critical but difficult process involving many uncertain factors and affected by dynamic conditions. The decision problem is essentially multi-objective. This research proposed a simulation based method that uses simulation to capture the complicated process flow and decision logic involved, and interface the simulation...
In order to simplify the optimization on workshop facility layout, a new approach is proposed in this paper by dividing the facilities in workshop to several rectangular production cells and introducing the concept of central point of material handling. Based on this idea, the objective function in aiming to minimize the cost of material handling is established and genetic algorithm method is applied...
For a lot of producers have never saved materials of their products for aims of economizing their time and saving costs, but when they have received orders, they will start from their locations with their production lines travel first to the material supply regions, second to the ordered regions, and product their products on the travelling time. Here, we consider their minimum travelling time routing...
According to requirements for grading and characteristics, mathematical model of linear vibrating screen with the pursuit of minimum power consumption per productive is established. By means of MATLAB optimization technology, the best design is acquired. The results show that power consumption per productive obtained from optimization is decreased significantly compared with empirical design.

This paper proposes a new control structure for automatic production lines. To handle the production lines flexibility and to solve the optimal control problem a new methodology is suggested. In our approach the production line workstations are connected sequential, coordinated and controlled with individual (industrial) Personal Computers (PCs) interconnected in grid. These computers are able to...
Material flow analysis (MFA) becomes more and more an important instrument to support environmental protection and sustainable development. Often, a special approach, life-cycle assessment (LCA), is put on the same level with material flow analysis. Based on the industrial ecology or industrial metabolism paradigm (Fischer-Kowalski 1998, Fischer-Kowalski and Hu??ttler 1999), we interpret material...
The keywords Green IT and Green Computing indicate a paradigm shift of computing. Development of existing and new technology should no longer proceed at the expense of environment. This is also true for automation. Nowadays, one important goal of automation is to optimize the complete work and material flow under the essential constraints of energy consumption, quality and throughput. As a matter...
Based on the characteristics that the agent system technology can divide the system into agent with independence and independent function, achieve the higher level system function, the new idea was put forward, which is merging the existing information system and new system developed and constructed in the future, solving the ubiquitous problem of "detached island of information", realizing...
The current business challenge and solution supported by EERP (End-to-End Resource Planning) is presented in this paper. An approach based on SOA and component technology for EERP has been proposed and applied, which can help to realize business-goal-driven dynamic semantic integration of the web services. After analyzing the profit points and service requirements in the refinery enterprise production...
The transport system with storage bin is widely used in mines, power plants, port terminals; material yards; grain depot, and etc. Theoretically storage bin have many virtues, such as reducing the interacting of links ahead and behind bin, buffering different transporting flows, adjusting and processing materials. In practical application, bin capacity size has great influence on reliability and production...
A multi-stage, multi-product, multi-constraint, and mixed continuous/batch plants planning problem is abstracted from production of diaphragm caustic soda, and the problem is formulated as a mathematic optimization model based on the objective to maximize the total profit with constraints involved resources, work manufacture processes and production capacity etc. An approach based on particle swarm...
