Development of a knowledge-based system for maintenance problem solving of split-type air conditioner : a case study of an air conditioner manufacturer
Abstract:
Air conditioner is one of primary facilities in most kind of buildings. Not only the price
and quality of product, the after-sales service is the essential issues to buy the product.
This study focuses on the after-sales service system, including the maintenance services, of
a case study company. According to the historical data, it shows the number of
unsuccessful services is 17.5%. These unsuccessful services affect the confidence and
satisfaction of customer. Moreover, it does increase the, service costs and time losses. This
study therefore proposes A Knowledge-Basedsystem for maintenance problem solving of
split-type air conditioner. A relational database management system is developed in orderto
store and share knowledge created by the after-sales service section. The system collects
the product data, problems, problem-solving methods, and also the relative information as
cases in order to be retrieved when a new problem occurred. The implementation of this
study enhances the accuracy of problem solving and reduces the number of unsuccessful
cases down to 10.7 %. In addition, it can reduce the service costs and time losses due to
unsuccessful services.
