Abstract    The decision making on selection of improvement solutions was one of the obstacles hampering the success of process improvement. This paper presents the House of Improvement (HOI) model as a guideline to link decision criteria for the prioritisation of improvement solutions. Three phases in the HOI are applied to facilitate selection and to ensure that suitable and value-added solutions are chosen. Each phase includes procedures for identifying, evaluating, and analysing the elements by establishing a relationship matrix. The reliability of each relationship matrix will be tested in order to proceed to the next phase. The adopted matrices in the HOI serve as decision-making tools for analysing potential and critical problems in the production line, evaluating possible effects of the critical problems, and innovating on the necessary actions for the solution. Using a real-life case study, this paper demonstrates the applicability and suitability of the HOI model in providing prioritised solutions for production problems experienced by small and medium enterprises.

چکیده    یکی‌ از موانع پیش روی موفقیت در فرایند بهسازی، تصمیم گیری برای گزینش روش مناسب می‌باشد. این مقاله، یک مدل مجموعه بهسازی به عنوان راهنمایهایی برای اولویت بندی شاخصهای تصمیم گیری گزینه‌های بهسازی ارائه میدهد. برای این منظور، از سه‌ فاز در مجموعه مدلسازی برای تسهیل انتخاب گزینه مناسب بهسازی و راه حل‌های با ارزش افزوده استفاده میشود. هر فاز شامل شناسایی، ارزیابی و تحلیل المانها از طریقه ساختن یک ماتریس وابستگی آجزا می‌باشد. میزان اطمینان پذیری هر ماتریس وابستگی به منظور اجرای فاز بعدی امتحان میگردد. ماتریس‌های اتخاذ شده در مجموعه بهسازی به عنوان یک ابزار تصمیم گیری برای تحلیل پتانسیلها و مسائل بحرانی در خطوط تولید، ارزیابی اثرات محتمل و نوآوری به منظور اقدام ضروری برای هر راه حل بکار برده میشود. این مقاله، قابلیت کاربرد و مناسب بودن مدل در آولویت بندی راه حلها برای مشکلاتی که کارآفرینان کوچک و بزرگ ایجاد میشود با استفاده از یک مورد مطالعاتی حقیقی‌ نشان میدهد.
