Application of Taguchi Approach to Forecast the Wages of Persian Silk Carpet Weavers
One of the remarkable phenomena in recent years is the growing trend of globalization. Iran is also seeking to join the World Trade Organization (WTO) to expand non-oil exports and presence in global markets, and is currently a member of the organization's oversight body. Handmade industries such as hand woven carpet are one of the important trades that can be studied for this purpose. Exports of handmade carpets have fluctuated over different time periods. Despite maintaining its international position as the rank of the largest exporter of handmade carpets, the export position of handmade carpets is decreasing as compared to other Iranian exports. Handmade carpet craftsmanship is a complementary activity of agricultural and rural businesses, but due to the considerable number of workers and the small share of carpet value added in the national economy, it does not have a suitable condition. Other influential parameters such as rivals (e.g., China, India, Pakistan, and Turkey), etc. have caused the economic conditions of this industry to be unstable. In this regard, one of the best and most appropriate ways to compete with other countries is to reduce production costs and, consequently, reduce product prices. This factor includes various variables, including weavers' wages. Unfortunately, there is no definite and elaborate program for determining the wages of handmade silk carpet weavers in Iran according to the standard. In fact, in some cities, the weavers' wages determine based on the texture conditions, texture parameters, economic conditions of the country, and other parameters by carpet wage boards that consist of several carpet experts. In this way, there is the possibility of mistakes and the loss of the rights of weavers or producers due to the entry of personal opinion and the failure to classify the effect of different parameters on the final point.
The main purpose of this study is to collect various parameters affecting the wages of handmade carpet weavers in Iran. According to a collection of statistical data obtained from the country's most popular producers, the effects of different parameters were investigated through the Design of Experiment (DOE). Finally, the effect of each parameter was expressed as a percentage using Taguchi Approach (TA). The most important achievement of this research is that the obtained results can be used to prevent the loss of rights of the people by providing an appropriate formula and detail table.
