Performance evaluation is a systematic way for companies to analyze their current status and progress to reach their goals. Companies constantly evaluate their processes in research and development, purchasing, production, sales and marketing departments in order to determine new ways to improve their capabilities. In this study, the authors proposed an evaluation model to evaluate the performance of small and medium enterprises (SME) which play a major role in country's economy under given high attention to “Production Process.” In the proposed model, Fuzzy Decision Making Trial and Evaluation Laboratory (F-DEMATEL) and Fuzzy Analytic Network Process (F-ANP) methods were used to calculate the weights of performance criteria. A case study has been conducted in a manufacturing SME for empirical evidence. The results from this study indicate that C5.1 (new processes on the current or new products are developed and applied expeditiously), C3.3 (products are delivered on time) and C5.3 (products are appropriate to environment, health, safety and regulatory policies) are the most important criteria for the company to which the model was applied. “C5 Process Management” and “C3 Production Planning” are declared as two important main criteria relevance to others.
