نمذجة خدمات التجارة الإلكترونية بالإعتماد على شبكات بتري الملونة
Abstract
دراسة وتحليل أداء خدمات التجارة الالكترونية عن طريق النمذجة هام للتثبت من اعتماد صحتها وإزالة الحالات غير المرغوبة منها، إذ أن ذلك يمكّن المصممين من استعراض واختبار سلوك الأنظمة قبل تطبيقهاـ وبالتالي فإن تقديم هذه الخدمات بالطريقة المثلى يمكن من تلبية احتياجات العملاء حيث يلعب الزمن دوراً هاماً.
نقدم في هذه الورقة حلولاً لبعض مشاكل نمذجة خدمات التجارة الالكترونية بالاعتماد على شبكات بتري الملونة، والتي كان من الصعب تحقيقها بالاعتماد على شبكات بتري غير الملونة، والفرضية الأساسية للعمل المطروح هي أنه بإمكاننا من خلال هذه النمذجة تحليل كفاءة أداء خدمات التجارة الالكترونية، وبالتالي تصحيح الأخطاء فيها إن وجدت ومن ثم تطوير هذه الخدمات نحو الأفضل بما يساهم في تطوير أداء خدمات نظم التجارة الالكترونية في القطر العربي السوري.
وقد تمت مقارنة طريقة النمذجة المقترحة مع الطرق الأخرى التي استخدمت لنمذجة خدمات التجارة الالكترونية. وقد تم انجاز ما أشرنا إليه من خلال تمثيل النظام ومحاكاته باستخدام المحاكي (CPN نسخة 3.0.2 كانون الثاني 2011).
Studying and analyzing E-commerce services are important to know their reliability and removing the undesirable cases in order to enable designers to browse and test the systems behavior before application. Thus, introducing these services in the best way contributes to providing all the clients' needs, with which time plays a major role. We present, throughout this paper, solutions to some of e-commerce services modeling problems depending on colored Petri net, especially those which cannot be solved depending on Petri nets. The basic thesis for the proposed idea is that we are able, through this modeling, to analyze the quality of the performance of e-commerce services, thus correcting the mistakes, if there are any. Developing these services contribute to developing e-commerce services performance in the Syrian Arab Republic. The proposed modeling method is being compared with other methods which have been used to simulate e-commerce services. All the above-mentioned can be done through representing and modeling the system, using colored Petri nets simulator (CPN version 3.0.2, January 2011).
