Tab titleAny project consists of a set of interconnected and interrelated activities in a specific order that are carried out at a specific time. The size of the projects, their high costs, and the complexity of their activities made it necessary to make a careful and prior planning. From here came the idea of business networks, where scientific analysis was adopted for project planning, scheduling and reviewing by representing these projects with a network that shows the sequence of their activities at appropriate costs and times. Since such networks need time and effort to implement, the researcher used one of the smart techniques (the weed algorithm) and applied it to some business network issues that require great time and effort that increase as the size of the project increases. By applying the algorithm to some of these issues, it succeeded in achieving the required results in a record time (a few minutes) and according to the size of the issue, and hardly a little effort, in the first issue, the results (the expected time for each activity, determining the critical path, calculating the time needed to complete the critical path) achieved results in approximately one minute, and the second issue took less than two minutes. As for the third issue, the results were given in approximately two and a half minutes. Thus this smart technology has achieved the desired results in the least possible time and effort. Such a technique can be used and implemented on problems in different fields due to its accuracy, efficiency and speed in solving problems. Keywords: Invasive Weed Optimization Algorithm; Network Analysis; (PERT) method.

يتكون أي مشروع من مجموعة من الأنشطة المتداخلة والمترابطة وفق ترتيب معين والتي تنفذ في وقت محدد. حجم المشاريع وارتفاع تكاليفها وتعقيدات نشاطاتها جعلها بحاجة إلى تخطيط مسبق ودقيق. من هنا جاءت فكرة شبكات الأعمال حيث اعتمد التحليل العلمي لتخطيط المشاريع وجدولتها ومراجعتها من خلال تمثيل هذه المشاريع بشبكة توضح تسلسل انشطتها بتكاليف واوقات مناسبة. وتحتاج مثل هذه الشبكات إلى وقت وجهد لتنفيذها من هنا جاءت فكرة البحث حيث قامت الباحثة باستخدام احدى التقنيات الذكائية (خوارزمية الأعشاب الضارة) وتطبيقها على بعض مسائل شبكات الأعمال التي تتطلب وقتا وجهدا كبيرين يكبران كلما كبر حجم المشروع , من خلال تطبيق الخوارزمية على بعض هذه المسائل نجحت في تحقيق النتائج المطلوبة في وقت قياسي (دقائق معدودة) وحسب حجم المسالة, وجهد لا يكاد يذكر, ففي المسالة الأولى حققت النتائج (الوقت المتوقع لكل نشاط, تحديد المسار الحرج, حساب الوقت اللازم لإنجاز المسار الحرج) في دقيقة تقريبا والمسالة الثانية في دقيقتين الا بضع ثوان اما الثالثة فلقد اعطت النتائج لها في دقيقتين ونصف تقريبا, وبهذا تكون هذه التقنية الذكائية قد حققت النتائج المطلوبة بأقل وقت وجهد ممكنين يمكن استخدام مثل هذه التقنية وتنفيذها على مسائل في مجالات مختلفة لما لهذه التقنية من دقة وكفاءة وسرعة في حل المسائل. الكلمات المفتاحية: خوارزمية الأعشاب الضارة، شبكات الأعمال، طريقة بيرت.
