چکیده

آنالیز فرآیند ارتباط تنگاتنگی با بهینه‌سازی فرایند دارد ودرآن بحث منابع نقش اصلی دارد. ازآنجا که مجموعه‌ی بهینه منابع به ویژه درشرایط رخداد حوادث غیر منتظره دارای اثرات متغیر در ریسک، عملکرد فرآیند و بازدهی آن است می‌تواند مشابه مدل انتخاب سبد بهینه سهام تعریف شود. هدف این مقاله، ارائه مدلی ریاضی برای تخصیص منابع انسانی بااستفاده از مدل مارکویتز براساس مهارت‌ها و هزینه‌ها و باهدف مینیمم کردن ریسک و ماکسیمم کردن بازده منابع است. مدل ارائه شده شامل ترکیبی از ارزیابی ریسک وبازده جهت پیدا کردن بهترین سبد ترکیب منابع در شرایط بحرانی است و روش حل محدودیت اپسیلون است. ازجمله نوآوری‌ها، مدل مارکوئیتز برای بهینه‌سازی تخصیص منابع و تخصیص مبتنی بر ریسک منابع است. مدل پیشنهادی در مطالعه موردی واحد اورولوژی یک مرکز فوق‌تخصصی کلیه استفاده شده است. نتایج نشاندهنده تخصیص منابع با بازده وریسک بهینه و بیشترین میزان خروجی در شرایط بحرانی باشد.

چکیده [English]

Process analysis is closely related to process optimization and in the optimization, the discussion of resources plays a major role. Since the optimal set of resources, especially in the event of unexpected events will have variable effects on risk, process performance and efficiency can be similar to the optimal stock portfolio selection model. The purpose of this paper is to provide a mathematical model for allocating human resources using the Markowitz model to the days of the week based on skills and costs, which the objective function minimizes the risk and maximizes the efficiency of resources. The proposed model includes a combination of risk and return assessments to find the best resource portfolio in critical situations. The study also used the Epsilon constraint method. The innovations of this research is the application of Markowitz model to optimize resource allocation and risk-based allocation of resources in the process. The proposed model has been used in a case study of a urology subspecialty kidney center. Numerical results show that using the designed model, resources can be allocated in such a way that it has optimal returns and risk, in order to produce the maximum amount of output in critical situations.
