This study developed a single resource-based virtual cell layout model constrained. Development of the model is intended to combine trade off between process layouts and cellular layouts so that the machine can be grouped into certain cells without physical transfer. The study was conducted without considering the factor of workers by grouping the component family continued with the determination of composition components and machines in each cell. Numerical examples in this study indicate that the results of virtual cell drafts can increase system productivity and minimize the overall lead time. Of the two computations carried out, there are 35 types of machines that are not allocated to any cell because they are not used to process the components studied. With the condition of the engine and workers who can work in parallel, it can be concluded that the process machining carried out by each worker does not exceed the planning period during 2 years (8064 hours). Therefore, the production of all component requests during the planning period can be fulfilled. The number of workers needed was 55 people. Real condition shows the existence of excess workers, where there are currently 150 people.
Application of writing
The problem of the machine layout, especially for conditions where the engine cannot be moved Physically can be solved by developing a virtual cell layout approach. This study proposes a model design of Maya Maya cell layout. Model input data In the form of processing processes of each component, the time of setup each family and data. Model produce output in the form of a number of virtual cells and the allocation of components processed at each Maya cells. The trial in a case study showed that the Maya cell formation was able The same setup activity into one cell so the total lead time decreases.
