Identifying the key factors for chiller system collaborative service design

This paper applies the Analytical Hierarchy Process (AHP) in calculating the weights and uses Cause–Effect Grey Relational Analysis (CEGRA) to rank system performance based on multiple criteria evaluation. AHP is compared with CEGRA in ranking the alternatives, thus achieving improved environmentally friendly system performance. This paper uses the TFT-LCD chiller in Taiwan to measure the model's reliability and validity through comparison with the traditional strengths and weaknesses assessment. Businesses should cooperate with collaborative vendors and apply the service science management concept to improve performance and reduce energy waste.
