چکیده

یکی از بخش‌های جدایی‌ناپذیر هر صنعت، سیستم نگهداری و تعمیرات (نت) آن است؛ ارتباط این بخش با دیگر بخش‌ها، دارای پویایی‌ها و بازخوردهای فراوانی است. ازاین‌رو پویایی‌شناسی سیستم‌ها، ابزار مناسبی است که می‌توان از آن برای تجزیه‌وتحلیل این بخش استفاده کرد. در این مقاله، نحوۀ تأثیر و تأثر سیستم نت و سایر بخش‌ها برای یک شرکت تولیدکنندۀ سیم و کابل، مدل‌سازی شده و در ادامه، پس از ایجاد نمودار جریان-انباشت، اعتبار مدل با سه آزمون بازسازی رفتار مرجع، رفتار حدی و حساسیت ارزیابی شده است. همچنین پس از اعتبارسنجی، اثر تغییر رویکرد فعلی شرکت در قبال سیستم نت، از نت اصلاحی به‌سمت نت پیشگیرانه، بررسی شده است. نتایج نشان می‌دهد تغییر این رویکرد از جنبه‌های مختلف به‌نفع شرکت است و سبب افزایش فروش و تعداد مشتریان شرکت می‌شود و مدیران باید توجه بیشتری به نت پیشگیرانه نشان دهند.

چکیده [English]

Maintenance is one of the Inseparable parts of each Industry and relations between this part and others consist of many dynamics and feedbacks. By this regard systems dynamic is a tool that can be used to analyze this part. In this paper for a company that produces Wire and cable, cause and effect (feedbacks) between maintenance and others part are modeled. After creating stock-flow diagram, model validation analyzed with Behavior Reproduction, Extreme Condition, and Sensitivity test. Also after model validation, effect of changing companies attitude from corrective maintenance to preventive maintenance, discussed. Results show this shifting is beneficial for company from different views and increase sales and customers. By this regard company managers should increase their Attention to preventive maintenance.
