Garment Manufacturing

In recent years, the way of competition has changed in terms of garment manufacturing. Quality and scale competition gradually turn into speed competition. Garment manufacturers need to shorten the production cycle to win development opportunities. This paper takes a garment manufacturing factory as the research object, and innovatively uses the MOST method and Em-Plant simulation to improve the efficiency of its production line. According to each activity, operation time and worker assignment of the garment manufacturing process, the corresponding simulation model based on Em-Plant software is created to reveal the current problems existing in the manufacturing process. By analyzing these results, the bottlenecks in the process are found out. Applying theoretical knowledge such as production line balancing, lean production, motion study and time analysis, the improvement two plans are put forward, and the corresponding simulation results are given subsequently. Finally, a relatively better improvement plan is determined, which can better achieve the goal of balancing production line, improving efficiency, and reducing cost.

On The Road

If an incident occurs on the road, the normal flow of traffic stream is interrupted and the road capacity reduces. This thus leads to huge social, economical losses, such as traffic congestion, air pollution, etc. This study was conducted to examine an effect on an incident management system by carrying out an simulation analysis and an social cost analysis. For the simulation analysis, incidents in a normal situation were compared with those in an incidental situation and thus travel time, queue length, and accident duration were selected as an evaluation indicator. It was analyzed that after an incident situation occurs, the length of vehicle in waiting rapidly increases and thus travel time also largely increases. To make an social cost analysis, vehicle operation cost (VOC) and vehicle operation time (VOT) were used an index. The results showed that travel time cost per driver and vehicle in an incidental situation all increased, compared with that in a normal situation. It was also observed that the longer the lasting hours are, the higher the travel time increases.

The current trend of the final product quality increasing is affected by time analysis of the entire manufacturing process The primary requirement of manufacturing is to produce as many products as soon as possible, at the lowest possible cost, but of course with the highest quality. Such requirements may be satisfied only if all the elements entering and affecting the production cycle are in a fully functional condition. These elements consist of sensory equipment and intelligent control elements that are essential for building intelligent manufacturing systems. Intelligent manufacturing system itself should be a system that can flexibly respond to changes in entering and exiting the process in interaction with the surroundings. Philosophy that we apply to solve the problem rise from intelligent assembly cell by building on our institute of manufacturing systems and applied mechanics Essential philosophy is integrate of interconnection between palletizing- depalletizing robot and Intelligent assembly system by the means mobile robot Robotino.

Microfluidic chips have a great prospect in the field of biochemical analysis with advantages of fast processes, high flux and low consumption. Molding and bonding are separated by the conventional procedure of hot embossing and bonding, resulting in low automation and long production cycle. In order to reduce cycle time and achieve mass production, this paper proposed In-mold Bonding technology with precisely controlled bonding pressure by injection molding machine’s movement of core-pulling. So simulation analysis for bonding process of PMMA microfluidic chip was carried out using finite element software to study microchannel distortion at different bonding temperature and pressure. The results show that, at a certain bonding pressure, when bonding temperature was lower than glass transition temperature(Tg), microchannel distortion didn’t change significantly, when bonding temperature was higher than Tg, microchannel deformation increases with increasing temperature. Small microchannel distortion was obtained at a temperature of 108°C,which was recommended as the suitable bonding temperature.

The existence of operational balance in each production lines may decrease the idle time; it shows that the productivity is increasing therefore it increases the production rate. The issues existed in the production process of hollow Dakota 1730 in PT. XYZ were 3 departments, from the result of the first observation, there was a bottleneck from each department and each production did not achieve the required target. Therefore, this research would fix the production line. The method used was ranked /positional weight. Based on the data processing by the ranked positional weight method, gained the total of work station in the production process of hollow Dakota 1730 by the number of 2 work stations. From the result of efficiency balancing, gained 62.5% and balance delay value was 37.5%. it shows that the balance performance between each department increases significantly.
