| Popis: | 105 As of July 2016, the total number of convenience stores in Taiwan has exceeded 10,000. The total population of Taiwan's population, with an average population of about 2,300 people, has a convenience store with a density of the world's highest. If the annual electricity costs of about 500,000 yuan per shop, the average price of 3.5 yuan / kWh, the current Taiwan region about more than 10,000 calculations, energy costs will be as high as about 50 billion yuan, power consumption of about 1.5 billion kWh. Convenience store is not like the department store or supermarket has a large store, so the density of electricity is quite high, this study case to facilitate the store as the object of study, the application of six standard deviation DMAIC method to improve the strategy and the use of management tools, combined with quality Expand the key factor to collect the convenience store 104 annual electricity situation and analysis of electricity data collected time load curve, the situation to improve the program. This study improved the manual improvement, improved after the implementation of a year in 105 years, compared with the results of the number of visitors and the results did not decline after the improvement, the verification results compared to 104 annual electricity costs by 20.51%, and provide contract capacity Change can save 20% of electricity costs, so for convenience stores is not only cost savings, but also reduce the consumption of the Earth's resources, to further achieve the effect of energy saving and carbon reduction. |
