The present invention relates to a process management analysis system and a process management analysis method, and more particularly, to a process management analysis system and a process management analysis method for calculating a time required to produce an electronic product and displaying them in graphs and tables on a screen in real time. It is about.

In general, a variety of processes are required to produce electronic products such as set-top boxes, digital versatile disk (DVD) players, and combos. That is, the assembly process of assembling electronic products, the adjusting process to match the characteristics of the assembled electronic products, the inspection process of inspecting the image and sound output from the electronic products with matching characteristics, and the inspection of the appearance of the finished electronic products. Appearance process must be followed.

Recently, more and more companies are producing electronic products by performing each process through a cell production method. The cell production method here is a self-contained production method in which the operator takes responsibility from the first to the final process without the conveyor line, which is considered a symbol of mass division production.

This cell production method is a one-person method in which one worker is responsible for and completes all processes from the first process to the final process in one cell according to the type of work. It is divided into three types: the circuit way to complete the process, and the divided way to complete the whole work process.

The cell production method is suitable for mass production of various kinds of products because the work can be performed in different cells for various order products. In addition, work efficiency increases as a small number of people are responsible for the entire process in one cell. In addition, in the existing mass production method, it is difficult to identify the responsible material for the defective stock, but in the cell production method, not only the responsibility is easily identified but also the learning effect is high.

Due to these advantages, an increasing number of companies are applying cell production methods to electronic product production. Accordingly, a process management analysis system suitable for cell production methods is required. That is, a process management analysis system is needed to monitor the process status in each cell to evaluate the overall process efficiency of each worker, to identify problems occurring in the process, and then to take measures and improve them to improve productivity.

And calculating at least one time required to produce the electronic product using the second detection signal to generate at least one of a graph and a table.

The computing device may further include a time required for each process of producing the electronic product, a total time required to produce the electronic product, an average time required to produce a plurality of electronic products, and the respective processes. At least one of the neck time, which is the time required for the most time-consuming process, is calculated to generate at least one of a graph and a table.

On the other hand, the process management analysis method according to the present invention comprises the steps of detecting the presence of the electronic product, transmitting and receiving a detection signal corresponding to the presence or absence of the electronic product in a Bluetooth (Blue Tooth) method, by using the detection signal Calculating a time required to produce the electronic product, and outputting the result of calculating the time required to produce the electronic product on at least one of a graph and a table.
