| Popis: | 99 The purpose of is balancing assembly lines is to maximize the proficiency of productions and assign the least possible operators and operation stands to balance the burden of every working part. In general, the more assembly lines are balanced, the higher their production efficiency is. However, if we take the cost of operating assembly lines into consideration, we find out that higher balance rates of the assembly line do not entail higher revenues. This is because there is no absolute correlation between the opportunity cost of imbalanced assembly lines and the overall cost. In real life, revenues are the most important issues for enterprises. Therefore, companies have to take the cost of balancing assembly lines into consideration in order to get the highest revenue possible. To determine the minimum cost for balancing assembly lines and understand the impact of output, usage rates and the overall cost on the maximum seconds provided before setting up operation stands, the research uses JAVA language and the rank positional weight method to balance the assembly line of the T company to figure out the overall cost under all the balanced assembly lines by considering its cost. To simulate actual productions, the research utilizes eM-Plant to imitate assembly lines in real situations to get its output, usage rate and overall cost in real life circumstance. The research concludes that when a company gets deals, it should choose the least proposed output to get the minimum production cost if it could present the products on time. It could get the minimum production cost by this means. Also, when it comes to arranging operation stands, it should assign an appropriate cycle time, neither too long nor too short. Otherwise, even if outputs or usage rates increase, the overall cost would increase, too. |
