The main directions of logistics activities are considered to be the pursuit of improving efficiency and reducing company costs. To achieve these goals, it is necessary to increase resource management efficiency, improve the company’s transport system, rationally use inventories, and increase the efficiency of logistics processes. These actions are essential for a company to compete efficiently and effectively in the market.
Measurement model for preparation and operational times
The presented model can be used in the analysis of both preparation times and the times of individual operations. It should be noted that depending on the machine, device, and process, it can be flexibly adapted.
Application of the SMED method for the analysis of the preparation time of a selected logistics process
In the case of using a measurement model for the analysis of preparation times in the studied logistics process, the SMED (Single Minute Exchange of Die) method can be applied, which verifies the preparation time, guaranteeing, while maintaining the aforementioned measurement model, an increase in the efficiency of its operation. The goal is to perform as many activities as possible while the process is still being carried out.
- Preparation time is the sum of times spent on external and internal activities.
- External time / activities are those that can be performed while the process is being carried out.
- Internal time, on the other hand, consists of activities that can only be performed when the process is not being carried out.
- The SMED method allows for distinguishing external time from internal time and for converting some preparation activities from internal to external.
According to the literature on the subject, the SMED method is used for changeover time, which is defined as the time between the last product on machine A and the start of work / operation on machine B.
