In recent years, the process of cellular manufacturing and group technology have received a lot of attention and popularity in many developed countries. By applying Group Technology (GT), many benefits of flow-line production can be attained in a batch production system. GT improves material handling significantly by reducing material flow time, distance, and setup times. In this paper, an earnest investigative attempt was made to provide valuable information regarding the use of Group Technology by applying to a real world jobshop system. The proposed GT model has the flexibility of choosing the number of cells required, which is very useful in examining different manufacturing cell configurations; or in case the workshop or factory prefers a certain number of work cells. The GT model results were found satisfactory and superior to other techniques in some cases.

Urgency of the research. Cell production has become one of the most important studies of the arrangement of production systems. This production philosophy is based on the fact that the products are similar in shape and production processes. This allows parts to be grouped into groups that they share during their processing, ensuring an economic effect.Target setting. Automated production systems are built with large investments. The result is small-scale production automation cells, including industrial robots, including handling automation. These automation islands did not meet expectations in terms of costs, commissioning dates, meeting production deadlines, achieving planned performances, so attention must be paid to integrated production. Actual scientific researches and issues analysis. Integrated production reduces material handling and transport time. By making the product more time on the machinery and less time on the road. Because the parts move in the chamber and not in the entire factory, travel time and distance are reduced, leading to a reduction in material handling costs, which represents between 20 and 50 % of the total operating costs. Uninvestigated parts of general matters defining. Most articles and other publications on the problem of modeling integrated manufacturing alleviate the problem of modeling a specific cell. In my article I will solve a production cell in general without specific properties. The research objective This paper focuses on the integrated and logistic of the style of material flow, suitable for realization manufacturing and logistics network. Solution base is defining of mission, objectives and goal integrated of the style of material flow. The core of solution is analysis of strategy on integrated. The result of solution is to define tools integrated and formation evolution profile of the style of material flow. The statement of basic materials.In general, the key to building integrated production is group technology based on the principle of material flow analysis. The problem of modeling integrated production points to possible variants of solutions based on the analysis of material flows. However, considering only this criterion is insufficient for practice, because it does not consider e.g. about the number of pieces. Conclusions. These relationships are representative of some approaching the importance of parameterization, which remains open and accessible to address other tasks to optimize the production system.

Ergonomic improvement in assembly line is the thing which the term generally refers to the scientific method of creating a favorable work and work space which demands to the ability of the workers. Ergonomic configuration is important to guarantee high efficiency, keep away from alignment and damage, and lift fulfillment and confidence among the workforce. More than satisfied and fulfilled workforce, work cells made of ergonomic structure offer noteworthy incentive to producers in terms of lesser output and worker compensation premiums. The system will be reactive or proactive when applying ergonomics. In reactive ergonomics, identifying current problems and take measures to correct them. In proactive ergonomics, seeing areas that can be improved and fix the issues before they become large problems. Each organization ensures the safety and comfortable environment of their workers, in turn they believe in increased quality and in performance ergonomically designed work cells and working equipments are the key area to be concentrated. In this study the problem is analyzed through pareto chart and cause and effect diagram one issue is taken as pallet transfer manual because of this manual pallet transferring workers facing issue like back pain and for this is a solution of ergonomically designed trolley to reduce worker fatigue and the productivity was improved by using major problem solving tools.

The streamline method was used to investigate the plastic strain rate in machining. The streamline function presented in this paper is a general equation with three parameters controlling the complex variation of flow line shape. Velocity and deformation field were obtained by streamline analysis. The validation of this model was conducted by comparing with other experimental results published. It shows that the streamline model presented in the paper can be applied to the evaluation of strain rate in machining.

In order to achieve the supply of materials on the concrete mixer assembly line timely and accurately, in this paper, the process, production features and actuality of materials supply on the concrete mixer assembly line were analyzed, the stations of the assembly was combined, and function mode of the storage was changed to active distribution. Then the material handling process was optimized using material handling design system. Finally, the effective implementation of material distribution was ensured based on the on-site management.
