| چکیده | ||
| فرآیند توسعه محصول دارای پیچیدگی خاص خود می باشد. این پیچیدگی هم می تواند ناشی از همپوشانی و هم به دلیل وابستگی متقابل (مزدوج بودن) بین فعالیت های موجود در یک فرایند توسعه محصول باشد. همپوشانی از یک طرف ممکن است مدت زمان یک پروژه را کاهش دهد اما از طرف دیگر خطر دوباره کاری را ایجاد می کند. علاوه بر این مزدوج بودن فعالیت ها نیز یکی دیگر از دلایل دوباره کاری محسوب می شود. این تکرار و دوباره کاری ناشی از همپوشانی و مزدوج بودن فعالیت ها منجر به افزایش زمان و هزینه پروژه می گردد. در این تحقیق برای بررسی ویژگی های فرایند توسعه محصول و همچنین ایجاد تعادل بین مدت زمان و هزینه اجرای یک پروژه توسعه محصول، یک مدل ریاضی ارائه گردیده است. با توجه به همپوشانی و میزان وابستگی متقابل بین فعالیت ها چهار نوع از حالت های زمانی مدل شده است. در ادامه به منظور راستی آزمایی، مدل فوق در نرم افزار متلب پیاده سازی شده و یک مثال نمونه حل گردیده و مشاهده می شود که مدل ارائه شده به سادگی قادر به محاسبه زمان و هزینه فرایند در حالات چهارگانه می باشد. | ||

| چکیده [English] | ||
| Product development process has its specific complexity. This complexity can also be due to overlapping and dependent relationships (coupling) amongst activities in a product development process. On one hand overlapping may reduce duration of a project on the other, it engenders rework risk. In addition, coupled activities are another reason for rework risk too. This iteration and rework caused by overlapping and coupling of activities results in increasing time and cost of the project. In this article, a mathematical model is presented to study the characteristics of the product development process and also to balance the duration and cost of it. According to the overlapping and the amount of dependent relationships among activities, four types of time models have been formulated. Furthermore to verify the process, the model has been implemented in MATLAB and an example has been solved. It is observed that the proposed model is easily able to calculate the time and cost of the process in all four types. | ||
