Abstract
Nowadays, outsourcing is considered one of the most critical strategies across various industries and sectors. A proper selection of activities for outsourcing results in organizational efficiency and focusing ability on competitive advantages, while an improper choice can lead to significant challenges. In this research, a comprehensive model is proposed for ranking outsourcing options in the service sector. The model calculates the weights of evaluation criteria based on different domains and can be applied across various job sectors.
Initially, 285 outsourcing decision-making criteria were identified. Using a structured questionnaire and the Lawshe method, these criteria were reduced to 25 key indicators, and their content validity was confirmed. Subsequently, the finalized criteria were categorized into the four perspectives of the Balanced Scorecard (BSC) using a fuzzy questionnaire. The criteria were then weighted using the Fuzzy SWARA method, and finally, the outsourcing alternatives in the case study, Amir al-Momenin Hospital, were ranked using the fuzzy RAS tool. were ranked using the Fuzzy ARAS method.
The results showed that restaurant, pharmacy, IT and technical support, and finance and accounting activities are prioritized for outsourcing with a desirability of 96%, 82%, 63%, and 36%, respectively. By providing a scientific and flexible approach, this model helps decision-makers in the service sector to make effective decisions for outsourcing by considering comprehensive indicators and appropriate weighting, thereby improving organizational productivity.
