توسعه یک ماتریس خطر برای ارزیابی تامین کنندگان تعمیر و نگهداری: مطالعه بر اساس دانش تجربی

The machinery maintenance plays a significant role achieving the final quality characteristics of the manufactured products. As the concept of quality covers tangible (e.g. dimensional tolerances) and intangible (e.g. lead-time), the assessment of maintenance suppliers is vital in maintaining the quality of a manufactured product at an anticipated level. As the maintenance suppliers play a significant role in the context of the availability of spare parts and other materials needed for the effective realization of the maintenance process in order to assure the overall quality of the manufactured products, it is vital to achieve the aforementioned via minimization of machinery down time and maintenance backlogs. This paper illustrates the adaptation of empirical-knowledge-based development for the assessment of spare parts and maintenance related other material suppliers. That development has been used only in the manufacturing material suppliers’ assessment so far. The criteria used in the case study manufacturing firm for the material suppliers’ assessment, as well as other relevant criteria published in the literature, are taken into consideration in the current study. The paper also presents a development of a risk matrix for the assessment of maintenance suppliers, which is the core for the risk based assessments, prioritization and control process.
